Django: all auth create account with email - unique constraint failed. Display message instead of giving an error

问题

I am using djnago all-auth to create custom user accounts. When creating an account with email and password, if account with a email already exits it gives an error (UNIQUE constraint failed: account_emailaddress.email) but I would like to display message that an account with this email already exists instead of throwing an error. What is the best way to handle this? In general I would use AJAX to verify and display message for my own views but I do not know how to deal here with django all-auth package.

回答1:

I'll suggest that you should override the signup/login form in order to manage this error. Have you checked the documentation? https://django-allauth.readthedocs.io/en/latest/forms.html

I think this answer is related to your question.

A relatively similar approach is given in this answer:

1. Create your custom view that inherits SignupView and overrides the form class
2. Create a custom form that inherits from SignupForm and overrides the email validation message
3. In your own urls.py add the following after include('allauth.urls') to override the account_signup url
