Update
1 2 3 4 5 | ->update(array('email' => 'john@example.com'))->update(array('column' => DB::raw('NULL')))->increment('column')->decrement('column')->touch() //update timestamp |
Delete
1 2 3 4 | ->delete()->forceDelete() // when softdeletes enabled->destroy($ids) // delete by array of primary keys->roles()->detach() //delete from pivot table: associated by 'belongsToMany' |
Getters
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | ->find($id)->find($id, array('col1','col2'))->findOrFail($id)->findMany($ids, $columns)->first(array('col1','col2'))->firstOrFail()->all()->get()->get(array('col1','col2')) ->getFresh() // no caching->getCached() // get cached result->chunk(1000, function($rows){ $rows->each(function($row){ });})->lists('column') // numeric index->lists('column','id') // 'id' column as index->lists('column')->implode('column', ',') // comma separated values of a column->pluck('column') //Pluck a single column's value from the first result of a query.->value('column') //Get a single column's value from the first result of a query. |
Paginated results
1 2 3 4 | ->paginate(10)->paginate(10, array('col1','col2'))->simplePaginate(10)->getPaginationCount() //get total no of records |
Aggregate
1 2 3 4 5 6 7 8 | ->count()->count('column')->count(DB::raw('distinct column'))->max('rating')->min('rating')->sum('rating')->avg('rating')->aggregate('sum', array('rating')) // use of aggregate functions |
Others
1 2 3 | ->toSql() // output sql query->exists() // check if any row exists->fresh() // Return a fresh data for current model from database |
Object methods
1 2 3 4 5 6 | ->toArray() //->toJson()->relationsToArray() //Get the model's relationships in array form.->implode('column', ',') // comma separated values of a column->isDirty()->getDirty() //Get the attributes that have been changed but not saved to DB |
Debugging
1 2 3 | DB::enableQueryLog();DB::getQueryLog();Model::where()->toSql() // output sql query |
