Register your models here.

class CustomUserAdmin(BaseUserAdmin):
    form = UserCreationForm
    add_form = UserChangeForm
    # The fields to be used in displaying the User model.
    # These override the definitions on the base UserAdmin

        ('Permissions', {'fields': ('is_admin','is_active',)}),
    )
    # add_fieldsets is not a standard ModelAdmin attribute. UserAdmin
    # overrides get_fieldsets to use this attribute when creating a user.
    add_fieldsets = (
        (None, {
            'classes': ('wide',),

admin.site.register(CustomUser, CustomUserAdmin)
admin.site.unregister(Group)

Please anyone try to let me know where am I missing something, I can't solve this, I also tried overriding the UserCreationForm for both Password1 and Password2 fields again to see if it works, but no luck. Seems it's the same

Answer 1

In your CustomUserAdmin try switching form and add_form values

Try:

class CustomUserAdmin(BaseUserAdmin):
    form = UserChangeForm
    add_form = UserCreationForm

add_form for creation of new users. form for editing

I hope this will help.
