Datatables using laravel-datatables-oracle getting Ajax error - laravel

Question

I am using http://datatables.net/and https://github.com/yajra/laravel-datatables-oracle. When I try search I get a popup with an "Ajax error" I seemed to have narrowed it down to being an issue when ever there is a join in the query.
Here is method used for the Ajax request (removed fields for simplicity):
$leads = Lead::leftJoin('lead_status', 'leads.status', '=', 'lead_status.id')
->select('leads.id', 'leads.email', 'lead_status.status');
This works fine as I said it is only when I try search do I get the error, I don't get it when sorting or paging through results.
When there is no join in the query then I don't get any issues.
Been on this for a while now and not sure what to do..

Answer 1

When using a join statement, you have to specify in js the fully qualified name of field. You should use table.column pattern. See example code below:
$('#posts-table').DataTable({
processing: true,
serverSide: true,
ajax: 'joins-data',
columns: [
{data: 'id', name: 'posts.id'},
{data: 'title', name: 'posts.title'},
{data: 'name', name: 'users.name'},
{data: 'created_at', name: 'posts.created_at'},
{data: 'updated_at', name: 'posts.updated_at'}
]
});
And on your controller
public function getJoinsData()
{
$posts = Post::join('users', 'posts.user_id', '=', 'users.id')
->select(['posts.id', 'posts.title', 'users.name', 'users.email', 'posts.created_at', 'posts.updated_at']);
return Datatables::of($posts)
->editColumn('title', '{!! str_limit($title, 60) !!}')
->editColumn('name', function ($model) {
return \HTML::mailto($model->email, $model->name);
})
->make(true);
}
