Laravel Eloquent: How to get only certain columns from joined tables

Question

I have got 2 joined tables in Eloquent namely themes and users.

theme model:

public function user() {
  return $this->belongs_to(         


        

Answer 1

This Way:

Post::with(array('user'=>function($query){
    $query->select('id','username');
}))->get();

Answer 2

I know, you ask for Eloquent but you can do it with Fluent Query Builder

$data = DB::table('themes')
    ->join('users', 'users.id', '=', 'themes.user_id')
    ->get(array('themes.*', 'users.username'));

Answer 3

I know that this is an old question, but if you are building an API, as the author of the question does, use output transformers to perform such tasks.

Transofrmer is a layer between your actual database query result and a controller. It allows to easily control and modify what is going to be output to a user or an API consumer.

I recommend Fractal as a solid foundation of your output transformation layer. You can read the documentation here.

Answer 4

In Laravel 4 you can hide certain fields from being returned by adding the following in your model.

protected $hidden = array('password','secret_field');

Answer 5

You can supply an array of fields in the get parameter like so:

return Response::eloquent(Theme::with('user')->get(array('user.username'));

UPDATE (for Laravel 5.2) From the docs, you can do this:

$response = DB::table('themes')
    ->select('themes.*', 'users.username')
    ->join('users', 'users.id', '=', 'themes.user_id')
    ->get();

Answer 6

If I good understood this what is returned is fine except you want to see only one column. If so this below should be much simpler:

return Response::eloquent(Theme::with('user')->get(['username']));
