Transform Laravel Eloquent result - laravel

Question

When I execute this in my Controller
$data = User::with('teams')->find(2);
return response(['data' => $data]);
I get this as result
{
"id": 2,
"country_id": 1,
"first_name": "John",
"last_name": "Doe",
"created_at": "-0001-11-30 00:00:00",
"updated_at": "2015-02-02 23:08:21",
"full_name": "John Doe",
"teams": [
{
"id": 1,
"name": "Helpdesk medewerker",
"description": ""
},
{
"id": 2,
"name": "Retentie",
"description": ""
}
]
}
Im not interested in the full teams data, but only interested in the teamNames of the user.
I've done this by adding this
$data->each(function($user) {
$user->team_names = $user->teams->lists('name');
unset($user->teams);
});
I was wondering if this is the correct way of modifying the Eloquent result.

Answer 1

You can use an attribute accessor for that. Add this to your model:
protected $hidden = ['teams']; // hide teams relation in JSON output
protected $appends = ['team_names']; // add custom attribute to JSON output
public function getTeamNamesAttribute(){
return $this->teams->lists('name');
}
To change hidden and appends dynamically you can use the setter methods:
$data = User::with('teams')->find(2);
$data->setHidden(['teams']);

Answer 2

Filter out the columns you want in your first build.
$data = User::with(['teams' => function($query){
return $query->select('name');
}])->find(2);
Will output:
{
...
"teams": [
{
"name": "Helpdesk medewerker"
},
{
"name": "Retentie"
}
]
}
You can also use the lists method.
$data = User::with(['teams' => function($query){
return $query->lists('name');
}])->find(2);
Will output:
{
...
"teams": ["Helpdesk medewerker", "Retentie"]
}
