Eloquent column list by key with array as values?

So I can do this with Eloquent:

$roles = DB::table('roles')->lists('title', 'name');

But is there a way to make Eloquent fetch an array of values for each distinct key instead of just one column?

For instance, something like the following:

$roles = DB::table('roles')->lists(['*', DB:raw('COALESCE(value, default_value)')], 'name');

Solution 1:

You can use the keyBy method:

$roles = Role::all()->keyBy('name');

If you're not using Eloquent, you can create a collection on your own:

$roles = collect(DB::table('roles')->get())->keyBy('name');

If you're using Laravel 5.3+, the query builder now actually returns a collection, so there's no need to manually wrap it in a collection again:

$roles = DB::table('roles')->get()->keyBy('name');

Solution 2:

If you need a key/value array, since Laravel 5.1 you can use pluck. This way you can indicate which attributes you want to use as a value and as a key.

$plucked = MyModel::all()->pluck(
  'MyNameAttribute', 
  'MyIDAttribute'
);

return $plucked->all();

You will get an array as follow:

array:3 [▼
   1 => "My MyNameAttribute value"
   2 => "Lalalala"
   3 => "Oh!"
]
