Hiding pivot attribute

Question

I know you can hide an entire pivot table as such

protected $hidden = ['pivot'];

How do you hide a specific field within pivot table, like

protected $hidden = ['pivot.created_at'];

The above does not work from what I've tested

Answer 1

After so much trying and looking into source of Laravel Model, i finally got it achieved.

Please put following method at your Model.

/**
 * Convert the model instance to an array.
 *
 * @return array
 */
public function toArray()
{
    $attributes = $this->attributesToArray();
    $attributes = array_merge($attributes, $this->relationsToArray());
    unset($attributes['pivot']['created_at']);
    return $attributes;
}

This solves the purpose.
