How to resolve conflict between user slug and service slug?

Question

Django

Hello!

urlpatterns = [
    url(r'^register/$', UserSignup.as_view(), name='signup'),
    url(r'^login/$', UserLogin.as_view(), name='login'),
    url(r'^logout/$', UserLogout.as_view(), name='logout'),
    url(r'^edit/$', UserSettings.as_view(), name='settings'),
    url(r'^feedback/$', Feedback.as_view(), name='feedback'),
    url(r'^(?P<slug>[-_\w]+)/$', UserDetail.as_view(), name='user_detail'),
]

If the user fills in the servants with one of the service names (for example: feedback) , then he will no longer get on his profile!
Doing url(r'^ user/ (?P[-_\w]+)/$', UserDetail.as_view(), name='user_detail') is somehow not very nice.
Do some extra validation on the form to check if the slug matches?
What do you advise? Thank you!

There was a similar situation. We check the user's slug field for matches with prohibited names in the user registration form:

class UserRegForm(AuthentificationForm):
...
    def clean_slug(self):
        slug = self.cleaned_data.get('slug')
        if slug in settings.PROHIBITED_NAMES:
            raise forms.ValidationError(u'Данное название уже было зарезервировано')
        return slug

In settings or in any other place, we store a list of prohibited slugs (look in your url pattern):

PROHIBITED_NAMES = ('article', 'accounts', 'admin', 'ckeditor',....)
