A website displays attachments(files) either as pdf, XMl (XRBL) . I want to see info in XRBL files the same way as i see pdf and not the actual text

A website display attachments(files) as either as pdf , XMl (XRBL) . I want to see info in XRBL files the same way as i see pdf and not the actual. Is there any chrome extension for the same. Ideally I want to click on it and when it open it in browser,some way in the browswer itself so that I can make sense from it. If not possible in browser then how best to see the contents in a visual format rather than as text.

Detecting .NET8 with Inno Setup and InnoDependenciyInstaller

I am looking at using InnoDependencyInstaller and it has a function that it uses under the hood:


Dependency_AddDotNet80
procedure Dependency_AddDotNet80;
begin

To detect .NET 8 using Inno Setup, you can use a combination of registry checks and custom code execution. Here's a basic example of how you can achieve this:

1. **Registry Check**: Check the registry to see if .NET 8 is installed. .NET 8 would be installed under a registry key specific to its version.

2. **Custom Code Execution**: If the registry check indicates .NET 8 is not installed, you can prompt the user to install it. You can execute custom code to check for the presence of .NET 8 assemblies or use InnoDependencyInstaller to install .NET 8 automatically.

Below is a sample script demonstrating how you can accomplish this:

```pascal

[Setup]

AppName=MyApp

AppVersion=1.0

DefaultDirName={pf}\MyApp

[Code]

function IsDotNet8Installed: Boolean;

var

  regKey: string;

begin

  // Check the registry to see if .NET 8 is installed

  regKey := 'Software\Microsoft\NET Framework Setup\NDP\v8\Full';

  Result := RegKeyExists(HKLM, regKey) or RegKeyExists(HKCU, regKey);

end;

procedure InstallDotNet8;

begin

  // Custom code to install .NET 8 or use InnoDependencyInstaller

  // Example:

  // ShellExec('open', 'https://dotnet.microsoft.com/download/dotnet/8.0', '', '', SW_SHOWNORMAL, ewNoWait, ErrorCode);

end;

function InitializeSetup: Boolean;

begin

  // Check if .NET 8 is installed

  if not IsDotNet8Installed then

  begin

    // Prompt the user to install .NET 8

    if MsgBox('This application requires .NET 8. Would you like to install it now?', mbConfirmation, MB_YESNO) = IDYES then

    begin

      InstallDotNet8;

      Result := False; // Abort setup

      Exit;

    end

    else

    begin

      // .NET 8 not installed and user declined installation

      MsgBox('.NET 8 is required to install this application. Setup will now exit.', mbError, MB_OK);

      Result := False; // Abort setup

      Exit;

    end;

  end;

  // .NET 8 is installed, continue setup

  Result := True;

end;

```

In this script:

- `IsDotNet8Installed` function checks the registry to see if .NET 8 is installed.

- `InstallDotNet8` procedure executes custom code to install .NET 8 or launches a browser to download it.

- `InitializeSetup` function is called before the setup begins. It checks if .NET 8 is installed. If not, it prompts the user to install it.

You may need to adjust the registry key path based on the specific registry location where .NET 8 is installed on your system. Additionally, replace the `InstallDotNet8` procedure with the appropriate code to install .NET 8 or utilize InnoDependencyInstaller to handle the installation automatically.

Enabling authentication in swagger

I created a asp.net core empty project running on .net6. I am coming across an issue when I am trying to enable authentication in swagger. Swagger UI runs as expected, the only issue is whenever I click on the Authorize green button on the swagger UI it will pop up but say Unknown Security definition type and give me two options Authorize and Close. It does not show under Available authorizations Bearer(http,Bearer) and allow me to enter a jwt value. I ran into this article that goes over bearer authentication but it isn't much help for me. Am I missing something in the .AddSwaggerGen()?



builder.Services.AddAuthorization();

builder.Services.AddSwaggerGen(options =>
{
options.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme
{
Scheme = "Bearer",
BearerFormat = "JWT",
In = ParameterLocation.Header,
Name = "Authorization",
Description = "Bearer Authentication with JWT Token",
Type = SecuritySchemeType.Http

{
new OpenApiSecurityScheme
{
Reference = new OpenApiReference

Symfony custom field type with data transformer not working properly when in an embedded collection form

I am having a problem in Symfony with a custom data transformer on a custom form field - but only when this is used in a collection/embedded form within my main form. If I use the same custom field type and transformer for field directly in the main form, then it works perfectly.
Basically I have an app that is a database of all of my music/films/etc. Each item is stored in an entity called AVItem. For each of these items I can have zero or more tracks and I do this with a CollectionType. Within this embedded form/collection I have simple text fields and also a Collection of EntityType and they all work perfectly when submitting the main form; however, only the one field that uses my custom field type and transformer does not.
My custom field is for a "duration". In the database I save any lengths of time purely as an integer of seconds; however, I display it and want it entered as a string in the form [HH:]mm:ss. When displaying, the custom field and transformer works, it reads the number of seconds from the entity and then the "transform" method correctly displays that as HH:mm:ss. However, when I submit the main form and one of those tracks has something entered into it, when the "reverseTransform" method is called, the value it receives is always null!
However, in my main entity, where I also have a filled called "totalRunningTime" which also uses the same custom field type and transformer, the transform and reverseTransform always work perfectly.
This seems to be an issue purely within the Collection/embedded form.
Does anyone have an ideas?
Here are some code snippets.


This is my custom data transformer:
class TimeDurationTransformer implements DataTransformerInterface
{
private ?string $invalidMessage = null;

public function __construct( ?string $invalidMessage = null )
{
$this->invalidMessage = $invalidMessage;
}

/**
* Transform an integer (number of seconds) into a string of the form HH:mm:ss.
*
* @param mixed $value
* @return mixed
*/
public function transform( mixed $value ) : mixed
{
if ( ( null === $value ) || ( intval( $value ) == 0 ) ):
return null;
endif;

return sprintf( '%02d:%02d:%02d', ( $value/ 3600 ), ( $value / 60 % 60 ), ( $value% 60 ) );
}

/**
* Transform a string of the form HH:mm:ss into a number of seconds as an integer.
*
* @param mixed $value
* @return mixed
*/
public function reverseTransform( mixed $value ) : mixed
{
if ( ( null === $value ) || empty( $value ) || ( strlen( $value ) < 1 ) ) :
return null;
endif;

$matchResult = preg_match( pattern: '/^((\d{1,3}):)?(\d{1,2}):(\d{1,2})$/', subject: $value, matches: $matches, flags: PREG_UNMATCHED_AS_NULL );
// If the string entered does not match the pattern, throw an exception
if ( ( false === $matchResult) || ( 0 === $matchResult ) ) :
throw new TransformationFailedException( message: $this->invalidMessage, invalidMessage: $this->invalidMessage );
else:
if ( $matchResult === 1 && ( count( $matches ) == 5 ) ) :
if ( round( $matches[4] ) != null ):
return( round( $matches[4] ) + ( $matches[3] ? ( $matches[3] * 60 ) : 0 ) + ( $matches[3] ? ( $matches[2] * 3600 ) : 0 ) );
endif;
endif;
throw new TransformationFailedException( message: $this->invalidMessage, invalidMessage: $this->invalidMessage );
endif;
}
}



This is my custom field type:
class TimeDurationType extends AbstractType
{
private $translator;

public function __construct( TranslatorInterface $translator ) {
$this->translator = $translator;
}

public function buildForm( FormBuilderInterface $builder, array $options ) : void
{
$builder->addModelTransformer( new StuggiBearTimeDurationTransformer( invalidMessage: $options[ 'invalid_message' ] ) );
}

public function configureOptions( OptionsResolver $resolver ): void
{
$resolver->setDefaults( [
'data_class' => null,
'required' => false,
'constraints' => [
new PositiveOrZero(),
],
'invalid_message' => $this->translator->trans( 'message.assert.time_duration_format' ),
'attr' => [
'placeholer' => '',
],
] );
}

public function getParent(): string
{
return TextType::class;
}
}



Within my main form for my entity AVItem, I have one field that uses this custom field type - and it works fine:
public function buildForm( FormBuilderInterface $builder, array $options ): void
{
$this->editType = $options['edit_type'];
$this->isWishlistItem = $options[ 'isWishlistItem' ];

$builder
...
->add( 'totalRunningTime', TimeDurationType::class, [
'required' => false,
'label' => $this->translator->trans( 'form.field.label.total_running_time' ),
'label_html' => true,
'attr' => [
'placeholder' => 'HH:mm:ss',
],
'empty_data' => null,
] )
...



Within this form I then have the collection of Tracks:
$builder
...

->add( 'tracks', CollectionType::class, [
'label' => $this->translator->trans( 'form.field.label.tracks' ),
'label_html' => true,
'entry_type' => TrackEmbeddedFormType::class,
'entry_options' => [
'label' => false,
],
'allow_add' => true,
'allow_delete' => true,
'by_reference' => false,
'empty_data' => [],
] )
...



...and then the embedded form type for the tracks:
$builder
->add( 'seriesEpisodeNumber', null, [
'required' => false,
'label' => $this->translator->trans( 'form.field.label.atce_series_episode_number' ),
] )
->add( 'title', null, [
'required' => ( $this->editType == FormEditType::SEARCH ) ? false : true,
'label' => $this->translator->trans( 'form.field.label.atce_title' ),
'label_html' => true,
] )
->add( 'additionalArtistsActors', EntityType::class, [
'required' => false,
'label' => $this->translator->trans( 'form.field.label.atce_additional_artists_actors' ),
'mapped' => true,
'class' => PersonGroup::class,
'by_reference' => true,
'multiple' => true,
'expanded' => false,
'choices' => [],
] )
->add( 'comment', null, [
'required' => false,
'mapped' => true,
'label' => $this->translator->trans( 'form.field.label.atce_comment' ),
'label_html' => true,
] )
->add( 'trackChapterNumber', null, [
'required' => true,
'label' => $this->translator->trans( 'form.field.label.atce_number' ),
'label_html' => true,
] )
->add( 'duration', TimeDurationType::class, [
'required' => false,
'label' => $this->translator->trans( 'form.field.label.atce_duration' ),
'label_html' => true,
'attr' => [
'placeholder' => 'HH:mm:ss',
],
'empty_data' => null,
] );
...



So, as I mentioned, the field "totalRunningTime" works perfectly with the data transformer, converting between integer seconds and a HH:mm:ss string and back.
However, the "duration" field within my collection/embedded tracks form only works reading from the database (the "transform" function works), but when I go to submit the form, the "reverseTransform" function always receives null.


If I change this field to be one of the standard types such as TextType or the like, then the value from the field seems to get passed.


Any help would be greatly appreciated.

I need help beefing up my A/B testing package

I developed a A/B testing package for laravel a while back ago and I'm bringing it back.
https://github.com/pivotalso/laravel-ab

Eventually I want to beef it up to back it with a SaaS, but I'd really like more laravel devs to test drive it so I can make sure large issues are handled.

I also plan on beefing it up into feature flagging/user flagging, but I want to make sure this package is useful before I dev it further.

There are examples on how to use it here

https://docs.pivotal.so/docs/ab/laravel/installation/

Please ignore images on the site, it's still all under development.
AND if you decide to try the reporting saas, ignore the payment stuff, I havent done payment and wont until I feel comfortable enough the project is worth something. submitted by /u/IAmRules

consume COM library from C# to rust

Question




I want to rewrite my project from C# to rust.
But I stuck in Segmentation Fault situation.
I think I misunderstood something, or meet crate limitation, hope for some help.


Rust Code






* find interface UUID
regedit capture

* find CLSID
regedit capture

* other id (I'm not sure shall we need it)
regedit capture



use windows::core::{GUID, HRESULT, IUnknown, IUnknown_Vtbl, interface};
use windows::Win32::System::Com::{
COINIT_APARTMENTTHREADED,
CLSCTX_ALL,
CoInitializeEx,
CoCreateInstance};

// define interface
#[interface("288EFDEC-3CF0-4F6C-8473-4E4CD47A93C7")]
unsafe trait Inhicshisx: IUnknown {
fn VPNGetRandomX(&self) -> HRESULT;
}

fn run() -> Result {
unsafe {
// 2F5AECD5-B5CD-41E1-8265-E2F6AA4548CB
const CLSID: GUID = GUID {
data1: 0x2F5AECD5,
data2: 0xB5CD,
data3: 0x41E1,
data4: [0x82, 0x65, 0xE2, 0xF6, 0xAA, 0x45, 0x48, 0xCB],
};

// initialize runtime
CoInitializeEx(Some(ptr::null_mut() as *mut c_void), COINIT_APARTMENTTHREADED)?;

// create COM object
let hisx: Inhicshisx = CoCreateInstance(&CLSID, None, CLSCTX_ALL)?;

// call object function
let value = hisx.VPNGetRandomX();
}

Ok(())
}



C# Part






* add a reference
regedit capture
* call function




using CSHISXLib;
string MyStr0;
CSHISXLib.Inhicshisx CSHISXLibObj = new CSHISXLib.nhicshisx();
MyStr0 = CSHISXLibObj.VPNGetRandomX();
Console.WriteLine(MyStr0);




* It works.






Update information




According to @IInspectable help, I can generate interface by oleview.exe tool.



* generated interface




[
odl,
uuid(288EFDEC-3CF0-4F6C-8473-4E4CD47A93C7),
helpstring("Inhicshisx Interface"),
dual,
oleautomation
]
interface Inhicshisx : IDispatch {
[id(0x00000001), helpstring("method VPNGetRandomX")]
HRESULT VPNGetRandomX([out, retval] BSTR* strRandom);
[id(0x00000002), helpstring("method VPNH_SignX")]
HRESULT VPNH_SignX(
[in] BSTR strRandom,
[in, optional, defaultvalue("")] BSTR strCardType,
[in, optional, defaultvalue("")] BSTR strServiceType,
[out, retval] BSTR* strRet);
}




* Rust code change




use windows::core::BSTR;

#[interface("288EFDEC-3CF0-4F6C-8473-4E4CD47A93C7")]
unsafe trait Inhicshisx: IDispatch {
fn VPNGetRandomX(&self) -> BSTR;
fn VPNH_SignX(&self, *mut BSTR, *mut BSTR, *mut BSTR) -> BSTR;
}



But it still cause Segmentation Fault, hope some advice 🙏

Check if value exists in enum in TypeScript

I receive a number type = 3 and have to check if it exists in this enum:
export const MESSAGE_TYPE = {
INFO: 1,
SUCCESS: 2,
WARNING: 3,
ERROR: 4,
};



The best way I found is by getting all Enum Values as an array and using indexOf on it. But the resulting code isn't very legible:
if( -1 < _.values( MESSAGE_TYPE ).indexOf( _.toInteger( type ) ) ) {
// do stuff ...
}



Is there a simpler way of doing this?

Why can I not see any of my points when adding them to my scene?

I have created a program for java fx to enter points in for an array. The points are to be shown with a line drawn between the maximal points. Also if you left mouse click it adds a point and recalculates the maximal points. If you right click it removes the point from the display. The problem I am running into is I am reading in a file with the points but nothing is showing in my display. I have even tried to manually add points and still nothing shows in the display. What am I missing?


I have tried everything I can to understand why no points are showing and am at a loss. I know it is something simple, but I cannot figure it out.
The points that should be added from the text file are

This is what it should look like when initially ran

This is what it actually looks like

I have corrected the mouse event so if I click in the upper left it will add points

Get absolute x,y of a child from the relative x,y of the parent

Note the following structure:


HTML:










CSS:
body {
padding: 100px;
background: aqua;
}

.container {
position: relative;
padding: 0 !important;
touch-action: none;
-webkit-user-select: none;
user-select: none;
width: 400px;
height: 400px;
border: 2px solid black;
}

.wrapper {
position: relative;
z-index: 1;
width: 100%;
height: 100%;
padding: 0 !important;
overflow: hidden;
background-color: black;
}

.image {
position: relative;
max-width: none !important;
max-height: none !important;
pointer-events: none;
width: 100%;
height: 100%;
transform: translate(var(--translate-x, 0px), var(--translate-y, 0px)) scale(var(--scale, 0));
--scale: 2;
--translate-x: 170px;
--translate-y: -100px;
}

img {
width: 100%;
height: 100%;
object-fit: cover;
object-position: center;
background: red;
}



If you prefer, here is the JSFiddle link.


When I click on the parent (.wrapper element) I will get an x,y. Let's suppose I click on the top right corner (in the example it would be close to the dog's eye). The value I should get relative to this element is something close to (x: 300, y: 0).


However, if we consider the real image (which has dimensions 1000x500) we know that this click region (the dog's left eye) corresponds to x:505 and y:205 (approximately).


What I want is precisely that. From the 5 variables:



* X of the click (relative to parent)

* Y of the click (relative to parent);

* CSS attribute --scale;

* CSS attribute --translate-x;

* CSS attribute --translate-y;






Get the absolute x, y of the image (considering its real size).


Comments:




The image can be moved within the container. For this I am using the Zoomist plugin. It was the only plugin I found that did this behavior of being able to zoom and move the image within a container of a pre-fixed size.


If there is another solution (another plugin for example) that would be better for my purpose, it would be welcome. Basically it all comes down to being able to zoom and move an image within a region and when clicking on a region (that is part of the image) I get its real x,y.

Step-by-step guide to linking gnuplot to Octave within Virtual Studio Code (VSC)

I am aware of a number of previous questions (here, here and here for example) pointing out to the need to modify a file named .octaverc.


Now, there are different files with that name (here). In Windows 11 and Octave 8.3.0 keeps two files in here:





I tried opening them with Notepad, and inserting the phrase graphics_toolkit("gnuplot") at the end, but I haven't been able to later save the file in any form due to lack of admin privileges even in my own laptop at home and logging in as admin (going to cmd line and setting up an admin profile just for this with net user administrator /active:yes).


Unfortunately, the extensions for Octave in VSC do not have too many preference options to link to gnuplot.


I am not sure how to set up a new .octaverc file in the working directory. Would it be for each folder? Would it be a text file? Would I find the wd from inside VSC? Would it also have to have the . of hidden file in the name? Would it bear an extension, such as .txt?


So I am lost and wasting a ton of time on an issue that is probably easy to solve with some more detailed steps.

Best Authentication Practice for Next.js (app router) with Laravel API

Hey everyone! I recently switched my frontend to Next.js (using the app router) while keeping Laravel for the API. What's the best way to handle user authentication now? I know Laravel recommends Sanctum with cookie-based sessions, but since Next's app router isn't a SPA, what are you all using? Cookies with Sanctum, tokens, or something else? Thanks for the insights! submitted by /u/Derperderpington

Using Timeframe parameters Pinescript indicator

I'm trying to create an indicator that uses the "Auto Fibo Retracement" technical indicator, but I want the timeframe on which the indicator is based not to be the one on the chart, but one to be selected in the indicator parameters.
I don't know what is the exact function to use and where into to code ?


Here is the code that I use :

I made this code, but I am not understanding how JavaScript is handling the swapping??? (I have seen this before in an article but didnt explain)

What is the name or official term of what I want to understand below in JavaScript??


I have never been able to find a clear article explanation of what arrays do behind the scenes when swapping numbers (I think this is a short way of replacing values, if im not wrong).




const swapNumbers = (numbers: number[]) => {
const swap = numbers.map((x: number, index: number) =>
index % 2 !== 0 ? numbers[index - 1] : index === numbers.length - 1 && numbers.length % 2 !== 0 ? numbers[index] : numbers[index + 1]);

console.log(swap);
};

swapNumbers([1, 2, 3, 4]);
swapNumbers([1, 2, 5, 6, 8]);





I want to understand what this is exactly doing (I want to understand the long way)... is this numbers[index + 1] (short way, which is placing the next number in line) the same as this (long way) numbers[index + 1] = numbers[index] or numbers[index + 1] = x?


What is the condition to be able to do this? (is it only in maps and other es6 functions? or can I use this in a regular for loop e.g. numbers[index - 1];?)

After upgrade to V11 from V10, all routes disappeared and no images are shown

Hi,

as i wrote in the title, after upgraded to V11, all my routes disappeared and no images are shown.
It seems like the framework cannot get the right path...

I am testing it on wamp, another project didn't have this issue.
I have installed (and use) spatie permission plugin, but even if i disable it, nothing changes.

Anybody had this problem? submitted by /u/djsnake81

Different types of Integer division in Python

In terms of the resulting value (ignoring the resulting data type), are the following the same in Python if x and y are both numbers?
int(x / y)

x // y



If so, which is better to use in real application? And why?


P.S. Are there any other methods in Python that achieve similar result but more suitable in different use cases? For example, if y is 2^n, then we can do bitwise shifting - that's all I know.

possible to delete a mongodb catch block

I have updated my mongodb driver which forces me to use two completion blocks: .then() .catch() instead of a single callback. The consequence of this is that any error in my stack down the line will jump back up to the mongodb .catch() and potentially cascade processes all over again. Any 'done' block should only be called once. Code that was once easily traceable and was called only once has lost it's simplicity and coherence when migrating from a single callback to two blocks: then() and catch().
DB.insertOne(something).then( (r) =>
{
done({success:true});
}).catch( (e) =>
{
done({success:false, message:e.code});
});



My question - is it possible to delete the catch block, once the insert command has successfully completed? I want to do this because I do not want the mongodb .catch() block executing when irrelevant and unrelated events crash occur down the line. I am looking for something like this.
DB.insertOne(something).then( (r) =>
{
delete this.catch;//does not work
done({success:true});
}).catch( (e) =>
{
done({success:false, message:e.code});
});



note also that I do need the catch block in general. I need the catch block to execute once - for example if the insert command were to return an error for attempting to insert the same document with the same ._id (for example).

Predicting on new data using locally weighted regression (LOESS/LOWESS)

How to fit a locally weighted regression in python so that it can be used to predict on new data?



There is statsmodels.nonparametric.smoothers_lowess.lowess, but it returns the estimates only for the original data set; so it seems to only do fit and predict together, rather than separately as I expected.



scikit-learn always has a fit method that allows the object to be used later on new data with predict; but it doesn't implement lowess.

Creating Your Own PHP Helpers in a Laravel Project

---



Laravel provides many excellent helper functions that are convenient for doing things like working with arrays, file paths, strings, and routes, among other things like the beloved dd() function.


You can also define your own set of helper functions for your Laravel applications and PHP packages, by using Composer to import them automatically.


If you are new to Laravel or PHP, let’s walk through how you might go about creating your own helper functions that automatically get loaded by Laravel.


Creating a Helpers file in a Laravel App




The first scenario you might want to include your helper functions is within the context of a Laravel application. Depending on your preference, you can organize the location of your helper file(s) however you want, however, here are a few suggested locations:




*
app/helpers.php


*
app/Http/helpers.php






I prefer to keep mine in app/helpers.php in the root of the application namespace.


Autoloading




To use your PHP helper functions, you need to load them into your program at runtime. In the early days of my career, it wasn’t uncommon to see this kind of code at the top of a file:
require_once ROOT . '/helpers.php';




PHP functions cannot be autoloaded. However, we have a much better solution through Composer than using require or require_once.


If you create a new Laravel project, you will see an autoload and autoload-dev keys in the composer.json file:
"autoload": {
"classmap": [
"database/seeds",
"database/factories"
],
"psr-4": {
"App\\": "app/"
}
},
"autoload-dev": {
"psr-4": {
"Tests\\": "tests/"
}
},




If you want to add a helpers file, composer has a files key (which is an array of file paths) that you can define inside of autoload:
"autoload": {
"files": [
"app/helpers.php"
],
"classmap": [
"database/seeds",
"database/factories"
],
"psr-4": {
"App\\": "app/"
}
},




Once you add a new path to the files array, you need to dump the autoloader:
composer dump-autoload



Now on every request the helpers.php file will be loaded automatically because Laravel requires Composer’s autoloader in public/index.php:
require __DIR__.'/../vendor/autoload.php';



Defining Functions




Defining functions in your helpers class is the easy part, although, there are a few caveats. All of the Laravel helper files are wrapped in a check to avoid function definition collisions:
if (! function_exists('env')) {
function env($key, $default = null) {
// ...
}
}




This can get tricky, because you can run into situations where you are using a function definition that you did not expect based on which one was defined first.


I prefer to use function_exists checks in my application helpers, but if you are defining helpers within the context of your application, you could forgo the function_exists check.


By skipping the check, you’d see collisions any time your helpers are redefining functions, which could be useful.


In practice, collisions don’t tend to happen as often as you’d think, and you should make sure you’re defining function names that aren’t overly generic. You can also prefix your function names to make them less likely to collide with other dependencies.


Helper Example




I like the Rails path and URL helpers that you get for free when defining a resourceful route. For example, a photos resource route would expose route helpers like new_photo_path, edit_photo_path`, etc.


When I use resource routing in Laravel, I like to add a few helper functions that make defining routes in my templates easier. In my implementation, I like to have a URL helper function that I can pass an Eloquent model and get a resource route back using conventions that I define, such as:
create_route($model);
edit_route($model);
show_route($model);
destroy_route($model);



Here’s how you might define a show_route in your app/helpers.php file (the others would look similar):
if (! function_exists('show_route')) {
function show_route($model, $resource = null)
{
$resource = $resource ?? plural_from_model($model);

return route("{$resource}.show", $model);
}
}

if (! function_exists('plural_from_model')) {
function plural_from_model($model)
{
$plural = Str::plural(class_basename($model));

return Str::kebab($plural);
}
}




The plural_from_model() function is just some reusable code that the helper route functions use to predict the route resource name based on a naming convention that I prefer, which is a kebab-case plural of a model.


For example, here’s an example of the resource name derived from the model:
$model = new App\LineItem;
plural_from_model($model);
// => line-items

plural_from_model(new App\User);
// => users




Using this convention you’d define the resource route like so in routes/web.php:
Route::resource('line-items', 'LineItemsController');
Route::resource('users', 'UsersController');



And then in your blade templates, you could do the following:

{{ $lineItem->name }}




Which would produce something like the following HTML:

Line Item #1




Packages




Your Composer packages can also use a helpers file for any helper functions you want to make available to projects consuming your package.


You will take the same approach in the package’s composer.json file, defining a files key with an array of your helper files.


It’s imperative that you add function_exists() checks around your helper functions so that projects using your code don’t break due to naming collisions.


You should choose proper function names that are unique to your package, and consider using a short prefix if you are afraid your function name is too generic.
