Best way to make admin site work in apps where USERNAME_FIELD is email?
I'm writing a Django app where users sign up and login with their emails rather than usernames. At first, I just changed the USERNAME_FIELD and set username=None on the Custom User Model. But then I noticed that this broke createsuperuser, and thus made the admin feature useless. What would be the best way around this? Should I still keep the username field and use it for the admin site, or should I just drop it and find a workaround? -

Matching either pattern with re_path in Django 3.0
I'm struggling to figure out how to use a regex with re_path in Django to match either of a set of patterns. I want to match /bucket/, /buckets/, /pail/, or /pails to a single view. In my primary urls file I've got: from bucket import urls as bucket_urls urlpatterns = [ re_path(r'^(?:bucket)s?/', include(bucket_urls)) ] and in the bucket.urls module I have: urlpatterns = [ path("new", views.BucketCreate.as_view(), name="create_bucket"), ... path('', BucketList.as_view(selection="recent"), name="buckets") ] This works for /bucket/ and /buckets/, as well as /bucket/new/ and /buckets/new/ as well as other urls extended from bucket(s). If I change it to '^(?:bucket|pail)s?/' none of the bucket(s) or pail(s) urls work. If I change it to '^(bucket)s?/' none of the bucket(s) urls work. If I understand correctly, this is because the () is capturing the bucket part and the ?: stops that? trying this works urlpatterns = [ re_path(r'^buckets?/', include(bucket_urls)), re_path(r'^pails?/', include(bucket_urls)), ] but gives this warning: ?: (urls.W005) URL namespace 'bucket' isn't unique. You may not be able to reverse all URLs in this namespace Should I worry about that warning? Any pointers on how I can match /bucket/, /buckets/, /pail/, or /pails/ with a single regex so I don't get the warning? -

Django queryset for intersecting ManyToMany relations fields
I have a difficult problem, I'm trying to select models related to each other with ManyToMany relations, depending on the intersection of the models present on each ManyToMany fields. I tried to achieve this with F() but without success, I don't think I'm skilled enough about DB/ORM to solve this. Here is a example: class Event(models.Model): want_private = models.ManyToManyField('User') class User(AbstractUser): events = models.ManyToManyField(Event, related_name='users') First I'd like to select events from a set of users, e.g. those starting with "a": users_a = User.objects.filter(username_startswith="a") So the queryset should be: Event.objects.filter(users=users_a) When it gets complicated is that I would like to: exclude events where a user is at the same time in the users field of the event, in the want_private field of the event, and in the users_a queryset. include events where a user is in at the same time in users field of the event, not in the want_private field of the event, and in the users_a queryset. Do anyone by any chance have an idea to solve this? Thank you very much, Camille. -
