Django how to reverse to autocreated page - django

Question

I have a CustomUser model and a UserProfile model. The UserProfile is linked to the CustomUser via a foreign key. A new UserProfile is auto created whenever a new CustomUser is created.
After a new CustomUser is added, I want to land on the UserProfile page so the person adding the user can also edit the profile. I have not been able to figure out how to specify the UserProfile id in the view for adding the new user.
The models:
class UserProfile(models.Model):
user = models.OneToOneField(CustomUser, null=True, on_delete=models.CASCADE)
preferred_name = models.CharField(null=True, blank=True, max_length= 75)
pronouns = models.CharField(null=True, blank=True, max_length= 40)
phone = PhoneField(blank=True, help_text='Contact phone number')
job_title = models.CharField(null=True, blank=True, max_length= 75)
birthdate = models.DateField(null=True, blank=True)
bio = tinymce_models.HTMLField(null=True, blank=True)
profile_image = ConstrainedFileField(
null=True,
blank=True,
upload_to='projects/employee_profiles',
content_types=['image/png', 'image/jpg', 'image/jpeg', 'image/gif'],
max_upload_size=2097152,
)
def create_user_profile(sender, instance, created, **kwargs):
if created:
UserProfile.objects.create(user=instance)
post_save.connect(create_user_profile, sender=CustomUser)
class CustomUser(AbstractUser):
full_name = models.CharField(max_length=250, null=True)
age = models.PositiveIntegerField(null=True, blank=True)
employee_type = models.ForeignKey(Group, null=True, on_delete=models.SET_NULL, default=1)
is_active = models.BooleanField(null=False, default=True)
The view:
class AddCompanyEmployee(CreateView):
model = CustomUser
template_name = 'manage/add_employee.html'
form_class = AddCompanyEmployeeForm
def get_success_url(self):
return reverse('userprofile_detail', args=[self.kwargs.get('userprofile_pk')])
The form:
class AddCompanyEmployeeForm(UserCreationForm):
class Meta:
model = CustomUser
fields = UserCreationForm.Meta.fields + ('email', 'full_name', 'age',)
The UserProfile URL:
from django.urls import path
from .views import EmployeeDirectory, UserProfileDetailView
urlpatterns = [
path('', EmployeeDirectory.as_view(), name='directory'),
path('profile/<int:pk>', UserProfileDetailView.as_view(), name='userprofile_detail'),
]
This is the error I get when I add a new user:
NoReverseMatch at /manage/add_employee/
Reverse for 'userprofile_detail' with arguments '(None,)' not found. 2 pattern(s) tried: ['user\\-profiles/profile/(?P<pk>[0-9]+)\\Z', 'directory/profile/(?P<pk>[0-9]+)\\Z']

You can work with:
class AddCompanyEmployee(CreateView):
model = CustomUser
template_name = 'manage/add_employee.html'
form_class = AddCompanyEmployeeForm
def get_success_url(self):
return reverse(
'userprofile_detail', kwargs={'pk': self.object.userprofile.pk}
)
It will look for the OneToOneField in reverse, and thus obtain the .pk of the related UserProfile.
That being said it is quite strange that you use both a CustomUser and UserProfile. Usually if you implement your own user model, that is to add fields that you would otherwise store in a UserProfile, and thus to prevent having to work with two models.
