Registering Filters

To register a filter option use the filter method.

protected function configure(): void
{
    ...
    $this->filter('name');
    ...
}

The filter will be performed by applying a where on a column with the same name.

{info} A request which tries to apply a filter which is not configured results in a 422 error response.

Custom Filters

When you want to add a custom filter to your Jory API you can add it as a second parameter. This class must implement the JosKolenberg\LaravelJory\Scopes\FilterScope interface.
FullNameFilter.php

use JosKolenberg\LaravelJory\Scopes\FilterScope;

class FullNameFilter implements FilterScope
{
    public function apply($builder, string $operator = null, $data = null): void
    {
        $builder->where('first_name', $operator, $data);
        $builder->orWhere('last_name', $operator, $data);
    }
}

MusicianJoryResource.php

protected function configure(): void
{
    ...
    // Search for musicians with a first or last name matching the search criteria
    $this->filter('full_name', new FullNameFilter);
    ...
}

{info} All filters are scoped, so any orWhere in a custom filter won't affect the rest of the query.

Filtering on Relations

Filtering on a relation's field doesn't require a custom FilterScope class, all registered filters in dot notation will automatically be translated into a filter on the relation using Laravel's whereHas.
MusicianJoryResource.php

protected function configure(): void
{
    ...
    // Search for musicians playing in a band which has an album with a name matching the search criteria
    $this->filter('band.albums.name');
    ...
}

Available Operators

The following operators are available for any filter: =, !=, <>, >, >=, <, <=, <=>, like, not_like, is_null, not_null, in and not_in.
Use the operators method if you want to change the operators for a filter.

protected function configure(): void
{
    ...
    $this->filter('number_of_albums_in_year', new NumberOfAlbumsInYearFilter)->operators(['=', '>', '<']);
    ...
}

{info} A request which tries to apply an operator which is not available results in a 422 error response.

Registering on a Field

If you want to register a field and a filter on the same column in one go you could use the filterable helper method when configuring a field.

protected function configure(): void
{
    ...
    $this->field('name')->filterable();
    ...
}

A callback can be added to set additional options.

protected function configure(): void
{
    ...
    $this->field('name')->filterable(function ($filter){
            $filter->scope(new CustomNameFilter);
            $filter->operators(['=', 'like']);
        });
    ...
}
