Query

# Request

It is often necessary to initially change the resource's queries all to the database.
You can easily override query builder in a resource. 

namespace App\MoonShine\Resources;
 
use App\Models\Post;
use Illuminate\Contracts\Database\Eloquent\Builder;
use MoonShine\Resources\ModelResource;
 
class PostResource extends ModelResource
{
    protected string $model = Post::class;
 
    protected string $title = 'Posts';
 
    //...
 
    public function query(): Builder 
    {
        return parent::query()
            ->where('active', true);
    } 
 
    //...
}

# Receiving a record

The resolveItemQuery() method is used, if you need to change the query to get a record from the database. 

namespace App\MoonShine\Resources;
 
use App\Models\Post;
use Illuminate\Contracts\Database\Eloquent\Builder;
use MoonShine\Resources\ModelResource;
 
class PostResource extends ModelResource
{
    protected string $model = Post::class;
 
    protected string $title = 'Posts';
 
    //...
 
    public function resolveItemQuery(): Builder 
    {
        return parent::resolveItemQuery()
            ->withTrashed();
    } 
 
    //...
}

# Search

The searchQuery() method allows you to change the query when searching for records. 

namespace App\MoonShine\Resources;
 
use App\Models\Post;
use Illuminate\Contracts\Database\Eloquent\Builder;
use MoonShine\Resources\ModelResource;
 
class PostResource extends ModelResource
{
    protected string $model = Post::class;
 
    protected string $title = 'Posts';
 
    //...
 
    public function searchQuery(): Builder 
    {
        return parent::searchQuery()
            ->withTrashed();
    } 
 
    //...
}

# Sorting

By overriding the resolveOrder() method, you can customize the records sorting. 

namespace App\MoonShine\Resources;
 
use App\Models\Post;
use MoonShine\Resources\ModelResource;
 
class PostResource extends ModelResource
{
    protected string $model = Post::class;
 
    protected string $title = 'Posts';
 
    //...
 
    protected function resolveOrder(): static 
    {
        if (($sort = request('sort')) && is_string($sort)) {
            $column = ltrim($sort, '-');
            $direction = str_starts_with($sort, '-') ? 'desc' : 'asc';
 
            if ($column === 'author') {
                $this->query()
                    ->select('posts.*')
                    ->leftJoin('users', 'users.id', '=', 'posts.author_id')
                    ->orderBy('users.name', $direction);
 
                return $this;
            }
        }
 
        return parent::resolveOrder();
    } 
 
    //...
}
