</div>

by default, it is loaded when specifying the address of the basket, an error is detected,
despite the fact that I wrote the name of the controller and the method correctly, still an error

Answer 1

Your controller can't find the view. Did you read the exception text? There, even the paths are written where the view should lie.

No, well, I understand, there were times when you had to take a form in one building, fill it out, hand it in in another building, the next day receive punched cards and carry them to the EC in another building, and the next day receive a printout ... But now F9-F10 is the happiness of step-by-step debugging right on the go...
