Django Allauth适配器无效：添加适配器后登录界面仍显示

Let's break down what's happening here and get your setup working as intended:

First, a quick clarification: Your NoNewUsersAccountAdapter with is_open_for_signup(self, request): return False does correctly block new user registrations—if someone tries to visit the /signup URL directly, they'll be denied access. However, this setting doesn't automatically remove registration links from the login page, nor does it hide the login interface itself (that's not what this adapter method is designed for).

Here's how to address the common issues you might be facing:

1. Double-Check Your Adapter Configuration #

First, make sure your setup is properly wired up—typos or missing app registrations are frequent culprits:

• Confirm the accounts app is listed in INSTALLED_APPS in your settings.py:

  INSTALLED_APPS = [
      # ... your other apps
      'accounts',
      'allauth',
      'allauth.account',
      'allauth.socialaccount',
  ]
  

• Verify your ACCOUNT_ADAPTER path is 100% accurate:

  ACCOUNT_ADAPTER = 'accounts.adapter.NoNewUsersAccountAdapter'
  

• Restart your Django server—adapter changes often don't take effect until you restart the process.

2. Remove Registration Links from the Login Template #

Allauth's default login template still displays signup links even when registration is disabled. To clean this up, override the template:

1. Create a templates/account folder inside your accounts app.
2. Copy the original login.html template from Allauth's package (you'll find this in your Python site-packages under allauth/templates/account/login.html) into this new folder.
3. Edit the copied template and delete or comment out the signup link section. Look for code like this:

   <p>{% trans "Don't have an account?" %} <a href="{{ signup_url }}">{% trans "Sign Up" %}</a></p>
   

3. Redirect Users Who Try to Access Signup Directly #

If you want to send users straight to the login page when they try to visit /signup, update your adapter with a redirect method:

from allauth.account.adapter import DefaultAccountAdapter
from django.shortcuts import redirect

class NoNewUsersAccountAdapter(DefaultAccountAdapter):
    def is_open_for_signup(self, request):
        return False

    def get_signup_redirect_url(self, request):
        # Send users to the login page instead of allowing signup
        return self.get_login_url(request)

4. If You Actually Want to Hide the Login Interface (Not Just Signup) #

If your goal was to disable login entirely (rather than just blocking new registrations), this adapter approach isn't the right tool. Instead, you'd need to:

• Use Django's permission system or middleware to restrict access to the login URL.
• Remove all login links from your site's templates.
• Adjust LOGIN_URL settings if needed to redirect unauthenticated users appropriately.
