• user avatar_name
• user avatar_filetype
• complete conversation_messages<

Answer 1

Take a look at this example of trying to join three tables staffs, customers and bookings(pivot table).

 $bookings = \DB::table('bookings')
        ->join('staffs', 'staffs.id' , '=', 'bookings.staff_id')
        ->join('customers', 'customers.id' , '=', 'bookings.customer_id')
        ->select('bookings.id', 'bookings.start_time',  'bookings.end_time', 'bookings.service', 'staffs.name as Staff-Name',  'customers.name as Customer-Name')
        ->orderBy('customers.name', 'desc')
        ->get();
    return view('booking.index')
            ->with('bookings', $bookings);

Answer 2

I had the following problem, simplified example:

$result = Donation::join('user', 'user.id', '=', 'donation.user_id')->where('user.email', 'hello@papabello.com')->first();

$result is a collection of Donation models. BUT CAREFUL:

both tables, have a 'created_at' column. Now which created_at is displayed when doing $result->created_at ? i don't know. It seems that eloquent is doing an implicit select * when doing a join, returning models Donation but with additional attributes. created_at seems random. So what I really wanted, is a return of all Donation models of the user with email hello@papabello.com

solution is this:

$result = Donation::select('donation.*')->join('user', 'user.id', '=', 'donation.user_id')->where('user.email', 'hello@papabello.com')->first();

Answer 3

Yeah, simply rename the column on either table and it should work. Also what you can do is, rename the user.name column to anything, also rename sender column of conversation_messages to id and perform a natural join.

Answer 4

Meh okay.. i've found a simple solution here

->select('users.name as userName', 'conversation_messages.*', 'user_avatars.name as avatarName', 'user_avatars.filetype')

As you can mention I've added the requested "as-Feature" next to the table.columnName
