rawColumns doesen't work with relation columns

[chojnicki]

Summary of problem or feature request

Hi. I cannot make datatables to work with columns in blade views. All works ok for regular columns, but not for relations. All these columns will print "[object Object]" in table ({} in json return). This happens only with blade files like "columns.user.login". In all files I have only "test" text (I can put exact same path in every column, and it will be error only in these with relation in it anyway).

If I remove rawColumns() or escapeColumns([]) then all works OK (but without rendering HTML of course).

What is weird - if I replace 'columns.user.login' with 'test' then again it works. Only not with separate blade files. Why?

I found similar problem here: #1151 It should be fixed, but no :(

I tried to test this with my old Laravel 5.5 instalation and datatables 8, and also same problem.

Is this bug? Any ideas? I

Code snippet of problem

$query = Video::select('id', 'title', 'user_id', 'created_at', 'updated_at')
   ->with('user:id,login');

return DataTables::eloquent($query)
   ->editColumn('title', 'columns.video.title') // works
   ->editColumn('user.login', 'columns.user.login') // nope
   ->addColumn('actions', 'columns.video.actions') // works
   //->escapeColumns([])
   ->rawColumns(['title', 'user.login', 'actions'])
   ->make();
