How to display error messages in a template?

Question

Django

I'm trying to write a registration on the site based on the built-in UserCreationForm. I want to do such an obvious thing as displaying a message to the user that the passwords do not match. And I don't understand how to do it. There, in this case, a ValidationError is raised in the form, and I don’t understand what to do with it.
I looked in Google, in the documentation, but I can not find anything. I probably don't look there. Even annoying, like some kind of nonsense.
I'm just starting to learn django if that :)

Answer 1

There is a standard battery, by default it is already connected django.contrib.message
You
can collect errors in the view in message.error
and display in the template as message.error

Answer 2

Validation on the server is fundamental?
Why drive data to the server and back, if this is how you can do everything quickly and cheaply on the frontend.
