Register User with custom fields in Djoser and Rest Framework - django

Question

I'm trying to use the "register" endpoint from Djoser. It works properly, but I need more fields than just "username", "email" and "password".
I've seen this question and indeed I can see the fields I wanted (in the browsable API). But when I try to post it, I get this error
ImproperlyConfigured at /account/register/ Could not resolve URL
for hyperlinked relationship using view name "user-detail". You may
have failed to include the related model in your API, or incorrectly
configured the lookup_field attribute on this field.
And I don't have idea what's going wrong.
My models.py looks so:
from django.db import models
class User(models.Model):
created = models.DateTimeField(auto_now_add=True)
email = models.CharField(max_length=100, blank=False)
name = models.CharField(max_length=100, blank=False)
last_name = models.CharField(max_length=100, blank=False)
birthday = models.CharField(max_length=15, blank=False)
password = models.CharField(max_length=100, blank=False)
class Meta:
ordering = ('created',)
the serializers.py
from rest_framework import serializers
from users.models import User
class UserSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = User
fields = ('url', 'id', 'email', 'name', 'last_name', 'birthday', 'password')
my views.py
from users.models import User
from users.serializers import UserSerializer
from rest_framework import viewsets
class UserViewSet(viewsets.ModelViewSet):
queryset = User.objects.all()
serializer_class = UserSerializer
and in the settings.py I added:
DJOSER = {
...
'SERIALIZERS': {
'user_registration': 'users.serializers.UserSerializer',
},
}
EDIT
App/urls.py
from django.conf.urls import url, include
from users import views
from rest_framework.routers import DefaultRouter
from rest_framework.schemas import get_schema_view
# Create a router and register our viewsets with it.
router = DefaultRouter()
router.register(r'users', views.UserViewSet)
schema_view = get_schema_view(title='Pastebin API')
# The API URLs are now determined automatically by the router.
# Additionally, we include the login URLs for the browsable API.
urlpatterns = [
url(r'^', include(router.urls)),
url('^schema/$', schema_view),
url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]
api/urls.py
from django.conf.urls import url, include
from django.contrib import admin
from rest_framework_jwt import views as jwt_views
from rest_framework import routers
router = routers.DefaultRouter()
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^', include(router.urls)),
url(r'^account/', include('djoser.urls')),
url(r'^auth/login/', jwt_views.obtain_jwt_token, name='auth'),
]
Does someone have an idea?

Answer 1

You can create a Custom User in django 2.0 using djoser by inheriting with AbstractUser, which creates a new user model with respect to your app like this:
from django.contrib.auth.models import AbstractUser
class User(AbstractUser):
FUNCTION = 1
VIEWER = 2
TECHNICIAN = 3
ROLE_CHOICES = (
(FUNCTION, 'Functional'),
(VIEWER, 'Viewer'),
(TECHNICIAN, 'Technician'),
)
role = models.PositiveSmallIntegerField(choices=ROLE_CHOICES, null=True, blank=True)
REQUIRED_FIELDS = ["email", "role"]
and then defined user new User class in settings.py:
AUTH_USER_MODEL = 'app_name.User'
Please note that here I have defined my REQUIRED_FIELDS. So when I use the djoser API /me/, it will give me all the required fields.

The exception is clear: Django cannot resolve URL by user-detail name. It tries to do so because you've made an extended serializer from serializers.HyperlinkedModelSerializer with a url field, which should contain a link to your specific user object.
The problem I see is that your main urls.py does not include api urls, and they all duplicated and wired up kinda strange. I would rewrite it as follows (assuming you also have user app):
Root urls.py:
from django.conf.urls import url, include
from django.contrib import admin
from rest_framework.schemas import get_schema_view
from rest_framework_jwt import views as jwt_views
schema_view = get_schema_view(title='Pastebin API')
urlpatterns = [
url('^schema/$', schema_view),
url(r'^admin/', admin.site.urls),
url(r'^user/', include('user.urls')),
url(r'^account/', include('djoser.urls')),
# Not sure if you need both:
url(r'^auth/login/', jwt_views.obtain_jwt_token, name='auth'),
url(
r'^api-auth/',
include('rest_framework.urls', namespace='rest_framework')),
]
User app urls.py:
from django.conf.urls import url, include
from rest_framework.routers import DefaultRouter
from .views import UserViewSet
router = DefaultRouter()
router.register(r'users', UserViewSet)
urlpatterns = [
url(r'^', include(router.urls)),
]
And I'm not sure why you need another app called api though.
If it doesn't help, try examining this article on namespacing the router.
