Relation Fields
In this section, we're going to talk about how Framework\Crud can help you handle relation fields.
Filtering by Relation
First, you need to define the relation in your model:
use Illuminate\Database\Eloquent\Relations\HasMany;
class Post extends Model
{
use Filterable;
public function tags(): HasMany
{
return $this->hasMany(Tag::class);
}
}
class Tags extends Model
{
use Filterable;
protected $filterFields = [
'title',
];
}
Now you're all set to apply relation filtering! You can find some examples on the filter examples page.
Sorting by Relation
Framework\Crud supports sorting by the following relationship types:
One to One
One to Many
Many to Many
Just like with filtering, you'll need to define the return type of the relations in your model:
use Illuminate\Database\Eloquent\Relations\HasMany;
class Post extends Model
{
use Sortable;
public function tags(): HasMany
{
return $this->hasMany(Tag::class);
}
}
Check out the sort examples page for some examples.
