Eager Loading Relationships(THIS WILL WORK JUST UNDERSTAND THIS)

DataTables support searching and sorting of eager loaded relationships when using Eloquent. this example will show you how to setup a eager loading search using Eloquent Engine.

To enable search, we need to eager load the relationship we intend to use using Laravel's User::with('posts') api.

use DataTables;

Route::get('user-data', function() {
$model = App\User::with('posts');

return DataTables::eloquent($model)
            ->addColumn('posts', function (User $user) {
                return $user->posts->map(function($post) {
                    return str_limit($post->title, 30, '...');
                })->implode('
');
            })
            ->toJson();
});

To trigger search on posts relationship, we need to specify the relation.column_name as the name attribute in our javascript appropriately.

Looking at {data: 'posts', name: 'posts.title'},:

data: posts represents the data key (data.posts) that we are going to display on our table. name: posts.title represents the User model relationship (posts) and the column we are going to perform our search (title).
