ERR_EMPTY_RESPONSE - Docker-Compose - Windows -Django
I just recently moved to windows 10 from linux and am now trying to run a dockerized django web-application but with no success.

Django form regrouping - How can I regroup a field form queryset like I would do in a template?

Django Model Property in Async Function Called from Sync View
I need to convert some of my Django views to work with async functions that query data sources. I'm experiencing big performance issues as those queries are executed one by one in series.

How to disable django-admin's change password, for users who signed up via LDAP server
We have an application where users can be uploaded via GUI. Other users of the application can come from a LDAP server. LDAP Server-backed users must not be able to change their django-admin password. The best, if they don't even have one. I know that there is a possibility to disable their password: user.set_unusable_password() Now the thing is that I must not disable the passwords for the GUI-uploaded users, only for those who came from a LDAP-server (because only LDAP-server backed users can access the application anyways). What is the best place and way to distinguish between the two? I've overridden create_user() in managers.py: class CustomUserManager(BaseUserManager): """ Custom user model manager where email is the unique identifiers for authentication instead of usernames. """ def create_user(self, email, password, **extra_fields): """ Create and save a User with the given email and password.

Do using queryset.count() caches the queryset?
