ModelResource

Queries

Queries

It is often necessary to initially modify all resource queries to the database. You can easily override the QueryBuilder in the resource.

 namespaces
namespace App\MoonShine\Resources;
 
use Illuminate\Contracts\Database\Eloquent\Builder;
use MoonShine\Laravel\Resources\ModelResource;
 
class PostResource extends ModelResource
{
    // ...
 
    protected function modifyQueryBuilder(Builder $builder): Builder
    {
        return $builder->where('active', true);
    }
}

If you need to completely override the Builder, you can override the resource method newQuery().

Receiving a Record

The modifyItemQueryBuilder() method is used if you need to modify the query for retrieving a record from the database.

 namespaces
namespace App\MoonShine\Resources;
 
use Illuminate\Contracts\Database\Eloquent\Builder;
use MoonShine\Laravel\Resources\ModelResource;
 
class PostResource extends ModelResource
{
    // ...
 
    protected function modifyItemQueryBuilder(Builder $builder): Builder
    {
        return $builder->withTrashed();
    }
}

If you need to completely override the Builder for retrieving a record, you can override the resource method findItem().

Eager Load

 namespaces
namespace App\MoonShine\Resources;
 
use MoonShine\Laravel\Resources\ModelResource;
 
class PostResource extends ModelResource
{
    protected array $with = ['user', 'categories'];
 
    // ...
}

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

 namespaces
namespace App\MoonShine\Resources;
 
use MoonShine\Laravel\Resources\ModelResource;
 
class PostResource extends ModelResource
{
    // ...
 
    protected function searchQuery(string $terms): void
    {
        $this->newQuery()->where(function (Builder $builder) use ($terms): void {
            // Your logic
        });
    }
}

If you only want to expand the query, you need to call the parent method.

 namespaces
namespace App\MoonShine\Resources;
 
use MoonShine\Laravel\Resources\ModelResource;
 
class PostResource extends ModelResource
{
    // ...
 
    protected function searchQuery(string $terms): void
    {
        parent::searchQuery($terms);
 
        $this->newQuery()->where(function (Builder $builder) use ($terms): void {
            // Your logic
        });
    }
}
 
You can also completely override the logic, including full-text search.
 
```php
protected function resolveSearch(string $terms, ?iterable $fullTextColumns = null): static
{
  // Your logic
 
  return $this;
}

Sorting

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

 namespaces
namespace App\MoonShine\Resources;
 
use MoonShine\Laravel\Resources\ModelResource;
 
class PostResource extends ModelResource
{
    // ...
 
    protected function resolveOrder(string $column, string $direction, ?Closure $callback): static
    {
        if ($callback instanceof Closure) {
            $callback($this->newQuery(), $column, $direction);
        } else {
            $this->newQuery()->orderBy($column, $direction);
        }
 
        return $this;
    }
}
