I can't Login to my django admin panel with my staff user

[mirolim-dev]

Note! I'm entering exact data belong to that user and I already set AUTH_USER_MODEL in my settings.py file

Extra description:

_I got Custom User model I'm changing user's staff_status by django signal after Adminstrator, Boss and Teacher models Created_

Finaly I solved this isue

I did it by changing my admin.py I gave form to add and change CustomUser. Because when I add new user by admin dashboard the old one wasn't save the password by hashing . That's whay The error was occuring while unhashing password and I wasn't be able to login to my Admin dashboard by staff user

Before I solve the isue CustomUser's admin form was like this 👇👇👇

from django.contrib import admin
from .models import CustomUser, Subject, Room

class UserAdmin(admin.ModelAdmin):
    list_display = ['id', 'username', 'first_name', 'last_name', 'email', 'is_active', 'is_staff', 'is_superuser']
admin.site.register(CustomUser, UserAdmin)    

I was be able to solve this isue by changing it to this 👇👇👇 After chaning

from django.contrib import admin
from .models import CustomUser, Subject, Room
from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.forms import UserCreationForm, UserChangeForm

# Register your models here.

class CustomUserAdmin(UserAdmin):
    fieldsets = (
        (None, {'fields': ('email', 'password')}),
        ('Personal info', {'fields': ('username', 'first_name', 'last_name', 'phone')}),
        ('Permissions', {'fields': ('is_active', 'is_staff', 'is_superuser', 'groups', 'user_permissions')}),
        ('Important dates', {'fields': ('last_login',)}),
    )
    add_fieldsets = (
        (None, {
            'classes': ('wide',),
            'fields': ('email', 'username', 'password1', 'password2'),
        }),
    )
    add_form = UserCreationForm
    form = UserChangeForm
    model = CustomUser
    list_display = ('email', 'username', 'is_staff', 'is_superuser')
    list_filter = ('is_staff', 'is_superuser', 'is_active', 'groups')
    search_fields = ('email', 'username', 'first_name', 'last_name')
    ordering = ('email',)

admin.site.register(CustomUser, CustomUserAdmin)
