Mute and Unmute Model Observers With Unobserve

 

Unobserve is a Laravel package by Stephen Lewis to mute and unmute observers at will.

When testing Laravel applications, we frequently need to “silence” events, so as not to trigger additional side-effects. Laravel’s Event::fake method is useful, but muting a specific model observer is still problematic.

Unobserve takes care of that, making it easy to mute and unmute an observer at will.

The usage of this package is simple: you use the package’s CanMute trait on model observers:

namespace App\Observers;

use Monooso\Unobserve\CanMute;

class UserObserver
{
    use CanMute;
}

With the trait in place, you can now mute and unmute your observer:

UserObserver::mute();

UserObserver::unmute();

Useful Laravel Validation Rule Packages

Laravel Validation Rules is a GitHub organization containing a collection of useful validation rules that you can pull into any project quickly and not have to write them yourself. At the time of writing here’s the list of validation rule packages:

• Colour (currently supports hex)
• Country Codes
• Credit Card
• IP
• Phone
• Subdomain
• Timezone
• US States and CA Provinces

Here’s an example from the documentation using the US states validation package:

use LVR\State\Abbr;
use LVR\State\Full;

# Abbreviation vs Full
$request->validate(['test' => 'UT'], ['test' => new Abbr]); // Pass!
$request->validate(['test' => 'BC'], ['test' => new Abbr); // Pass!
$request->validate(['test' => 'Utah'], ['test' => new Full]); // Pass!
$request->validate(['test' => 'Alberta'], ['test' => new Full]); // Pass!

# Abbreviation - USA vs Canada
$request->validate(['test' => 'UT'], ['test' => new Abbr]); // Pass!
$request->validate(['test' => 'UT'], ['test' => new Abbr('US')]); // Pass!
$request->validate(['test' => 'BC'], ['test' => new Abbr('CA')); // Pass!

# Full - USA vs Canada
$request->validate(['test' => 'Utah'], ['test' => new Full('US')]); // Pass!
$request->validate(['test' => 'Alberta'], ['test' => new Full('CA')]); // Pass!
