In my django app, I've created a custom User model which extends AbstractUser. I updated the AUTH_USER_MODEL and registered it under the admin like so
admin.site.register(MyUser, UserAdmin)
I ran the migrations and then went under my admin page and saw it listed under the app's models. But when I tried created a new user from that page, it gave me this error.
User class in models.py:
class MyUser(AbstractUser): id = models.CharField(primary_key = True, unique = True, max_length = 50) Any ideas? Edit: updated to include main urls.py
from django.conf.urls import url, include from django.contrib import admin urlpatterns = [ url(r'^admin/', include(admin.site.urls)), url(r'^api/', include('api.urls')) ] Edit 2: updated to include stacktrace

You've replaced your primary key with a CharField but you're still using Django's UserAdmin ModelAdmin. Django's UserAdmin doesn't ask for the ID – it's defaulting to an empty string. (You can verify this by checking for the empty string in the arguments from the NoReverseMatch Exception.)
You need to create a ModelAdmin that allows you to specify the ID so it doesn't end up as an empty string. The following admin.py will allow you to specify the ID thus getting rid of your NoReverseMatch exception.
# -*- coding: utf-8 -*- from __future__ import unicode_literals from django.contrib import admin from django.contrib.auth.admin import UserAdmin from .models import MyUser class MyUserAdmin(UserAdmin): add_fieldsets = ( (None, { 'fields': ('id', 'username', 'password1', 'password2'), }), ) # Register your models here. admin.site.register(MyUser, MyUserAdmin) Answers 2
you'd have register your model in admin site
from django.contrib import admin from django.contrib.auth.admin import UserAdmin from .models import User admin.site.register(User, UserAdmin) also you must have your model with id with integer number
class MyUser(AbstractUser): pass Answers 3
The error message shows the url as /myuser/add and your urls say it only have the /myuser/change/ defined. Define the /myuser/add class/function view or update the url to point to the add class/function view.
