Get "this field is required" in django-auth-registration

What I want to do

Make a user to register to django Authentication

Version

django : 3.1

djangorestframework:3.11.1

python : 3.7.6

django-allauth : 0.42.0

django-rest-auth : 0.9.5

Situation

I entered a registration page that django provides by accessing to localhost:8000/rest-auth/registration/. In order to register to the site, I entered username, password1 and password2 in fields. However, every time I sent POST request, I got an error and that says it below.

{
    "password1": [
        "This field is required"
    ],
    "password2": [
        "This field is required"
    ]
}

I absolutely typed exact same passwords in these fields. And, I do really not know why I get this error although I surely entered passwords.

How could I fix it out? I would like you to teach me how to do that.

Thank you very much.enter image description here

I recreated my django project and create a new User model by extending User which Django originally provides with us like above. However I still have the same issue.

Solution

  • Finally, I figured it out. I edited RegisterSerializer then it worked.
