Translating raw SQL to Eloquent

Question

Help me please with this query.

SELECT d.date, d.id, d.message, u.username 
FROM dialogs d JOIN users u ON d.user_id = u.id 
AND d.is_deleted = 0 
WHERE d.id > ? ORDER BY d.id DESC LIMIT 30

There are messages with authors. Now I'm using DB::select for this query, but want something like:

Dialog::all(['date', 'id', 'message'])
            ->where('is_deleted', '=', 0)
            ->with('user')
            ->idDescending()
            ->take(30)
            ->get();

Laravel 4.2

Little adition. Works only if list of selected fields contains both local and foreign keys.

Dialog::with('user') ->where('is_deleted', '=', 0) ->orderBy('id', 'desc') ->take(30) ->get(['date', 'id', 'message', 'user_id']);

public function user() { return $this->belongsTo('User')->select(['username', 'id']); }

If there no keys, user is null.

If you have your relation setup correctly this should be good:

$rows = Dialog::with('user') ->where('is_deleted', '=', 0) ->orderBy('id', 'desc') ->take(30) ->get(['date', 'id', 'message'])

You should be able to access the user with

foreach($rows as $row){ $row->user->username; }
