Database [] not configured Laravel 5

Question

I create new db in phpmyadmin and new tables.

Then i do

    public function next(Request $request){
    $langs = DB::connection(\'mydb\')->select(         


        

Answer 1

In my case I used 2 db connections and the second added was not cached, the command call: php artisan config:cache did the trick.

To see what's going on it was sufficient to output the $connections variable in DatabaseManager->configure method.
