The issue is that you have:

which is extending this from the base UserAdmin class:

    add_fieldsets = (
        (
            None,
            {
                "classes": ("wide",),
                "fields": ("username", "usable_password", "password1", "password2"),
            },
        ),
    )

You can see the usable_password field defined in the add_fieldsets attribute.

Your CustomUserAdmin, which is inheriting from UserAdmin, defines add_form = CustomUserCreationForm. Your CustomUserCreationForm inherits from UserCreationForm.

However, if you look at the UserAdmin class definition, you’ll see that it defines add_form = AdminUserCreationForm.

It looks to me that you’re probably creating your CustomUserCreationForm as inheriting from the wrong class.

Then what to do next? Which class to inherit?

What form class does the UserAdmin class use for the add_form attribute?

If you’re going to inherit from AbstractUser and modify its behavior, you’re going to want to parallel its settings precisely.

but nothing to change bro

What did you change here? If you fixed your CustomUserCreationForm, please post the new version.

class CustomUserCreationForm(UserCreationForm):
    class Meta(UserCreationForm):
        model = CustomUser
        fields = ('username', 'first_name', 'last_name', 'email',)

you said that

What class did I say the UserAdmin class uses for the add_form attribute?

Instead of extending the add_fieldsets from the UserAdmin, rather override the add_fieldsets attribute.
The UserAdmin class inbuilt into django ships with a usable_password attribute which your customuser does not have. So you override that attribute with your own custom fields that does not include usable_password.

add_fieldsets = (
(
None,
{
“classes”: (“wide”,),
“fields”: (“username”,“email”,“age”, “password1”, “password2”),
},
),
)
This should fix it.
