การลงทะเบียนด้วย UserCreationForm

Login assumes accounts already exist. To let visitors create their own, you need a registration view backed by a sign-up form. ✍️

Django gives you UserCreationForm, a ready form with username and two password fields that creates a User on save.

The form confirms the two passwords match and runs Django's strength validators, so weak or mismatched passwords are rejected automatically.

On a GET request, create an empty form and render it. This is the blank sign-up page the visitor first sees.

On a POST, build the form with request.POST so it holds the submitted values, ready to validate.

Call is_valid(); if it passes, form.save() inserts the new user with a properly hashed password. One line creates the account.

A smooth flow signs the user in immediately after sign-up. Call login() with the saved user so they skip a second step.

When validation fails, just render the same form again. It carries error messages that tell the user exactly what to fix.

Your template wraps the form in a POST and adds csrf_token. Output the fields and a submit button to finish the page.

Need an email field? Subclass UserCreationForm and add it. The built-in form keeps things minimal until you ask for more.

Finish by sending the new user somewhere useful with a redirect, like their dashboard, instead of re-rendering the form.

What does UserCreationForm verify about the password automatically?

You used UserCreationForm to validate sign-ups, saved the new user with a hashed password, and logged them in right away. ✅
