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

On Laravel 5.5, the cleanest way to do this is:

Theme::with('user:userid,name,address')->get()

You add a colon and the fields you wish to select separated by a comma and without a space between them.

Answer 2

Check out, http://laravel.com/docs/database/eloquent#to-array

You should be able to define which columns you do not want displayed in your api.

Answer 3

Using with pagination

$data = DB::table('themes')
->join('users', 'users.id', '=', 'themes.user_id')
->select('themes.*', 'users.username')
->paginate(6);

Answer 4

Using Model:

Model::where('column','value')->get(['column1','column2','column3',...]);

Using Query Builder:

DB::table('table_name')->where('column','value')->get(['column1','column2','column3',...]);

Answer 5

Change your model to specify what columns you want selected:

public function user() {
  return $this->belongs_to('User')->select(array('id', 'username'));
}

And don't forget to include the column you're joining on.

Answer 6

user2317976 has introduced a great static way of selecting related tables' columns.

Here is a dynamic trick I've found so you can get whatever you want when using the model:

return Response::eloquent(Theme::with(array('user' => function ($q) {
    $q->addSelect(array('id','username'))
}))->get();

I just found this trick also works well with load() too. This is very convenient.

$queriedTheme->load(array('user'=>function($q){$q->addSelect(..)});

Make sure you also include target table's key otherwise it won't be able to find it.
