why can't I log in into any account until I reset its password in django admin?

Question

I have a Profile model that has a one to one relationship with the User model from django.contrib.auth.models , when I add a new profile from the admin panel I noticed that the password field is not transformed into dots when typing , it shows the actual password , that's not the issue though , the issue is , when ever I create a new profile which in turns creates a new User , and mark the is staff attribute as true, I can't log in into the admin panel with that created account, unless I reset the password manually with

python manage.py changepassword the-user-name

after I have reset the password and only then even with the same password, I can log in into the account normally, does anybody know why is that happening ? I made sure it's not a mistake in typing the password and I tried it several times until I made sure that this is what is actually happening

Update

when I enter the Users model from the Authentication and Authorization section opposed to entering it from the app name, I find that written besides the password section

Invalid password format or unknown hashing algorithm

how can I fix it ?

I forgot to say that I am using an UpdateView from generic views , and using the model Profile as the the model attribute set on that view

the code of my update view

class ProfileUpdate(UpdateView):
    model = Profile
    fields= [
        'username',
        'bio',
        'avatar_thumbnail',
        'location',
        'tags',
        'contact_information'
        ]
    def get_object(self):
        return Profile.objects.get(pk = self.kwargs.get('user_pk'))

    def get_queryset(self):
        base_qs = super(ProfileUpdate, self).get_queryset()
        return base_qs.filter(username=self.request.user.username)

Answer 1

That would inherit from ModelAdmin instead of UserAdmin in your admin.py.

Can you instead try this:

from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.models import User
from app.models import Profile

class ProfileAdmin(UserAdmin):

   def __init__(self, *args, **kwargs):
      super(UserAdmin,self).__init__(*args, **kwargs)
      UserAdmin.fieldsets += (('profile', {'fields': ('attr1', 'attr2')}),)

admin.site.unregister(User)    
admin.site.register(Profile, ProfileAdmin)

Explanation

When you registered the Profile admin like so, admin.site.register(models.Profile), internally it was inheriting from ModelAdmin class which is perfect for all other classes. But for User we need hashing for saving the passwrd field, so there is a separate class UserAdmin that must be inherited from.

Once you inherited, the password issue was resolved but since the base model was UserAdmin, only user related fields were showing. We needed to append the profile fields for which we added the __init__ method and appended the profile fields to the admin section.
