->select('content','name','to_id')
->where('to_id','=',auth()->user()->id)

return view('conversations/show',compact('users','user','messages'));
}

Answer 1

You need to join the tables based on a foreign key. Like:
->join('users', 'users.id', '=', 'message.user_id')
and you need to specify the table in "select" and "where" after joining. Like:
->select('message.content','users.name','messages.to_id')
->where('message.to_id', auth()->user()->id)
and instead of:
->join('users', 'users.id','=', $user->id)
do this after joining:
->where('users.id', $user->id)

Answer 2

You need to correct your join clause in messages query.
$messages = DB::table('message')
->join('users', function($join) use($user) {
$join->('users.id', '=', 'messages.user_id')
->where('users.id', '=', $user->id)
})
->select('content','name','to_id')
->where('to_id','=',auth()->user()->id)
->get();
