/**
|
|
* This trait allows for cleaner searching of models,
|
|
* moving from complex queries to an easier declarative syntax.
|
|
*
|
|
* This handles all the out of the box advanced search stuff (using the "advanced search" bootstrap table plugin),
|
|
* allowing you to just define which attributes and relations should be searched, and then it does the rest.
|
|
*
|
|
* You can override these trait methods (for example, advancedSearch) if you need different behavior, but this really
|
|
* should cover most of the use cases, and allows you to easily add searching to your models without having to
|
|
* write complex queries.
|
|
*
|
|
* To use this:
|
|
*
|
|
* 1. Make sure the model has $searchableAttributes and $searchableRelations set
|
|
* 2. Make sure you import the App\Models\Traits\Searchable trait and use Searchable in the model
|
|
* 3. Make sure you check the request for the request input filter or search and then invoke the TextSearch scope, like:
|
|
*
|
|
* if ($request->filled('filter') || $request->filled('search')) {
|
|
* $whateverModel->TextSearch($request->input('filter') ? $request->input('filter') : $request->input('search'));
|
|
* }
|
|
* 4. Set the "data-advanced-search="true" in the
