Django & GDAL - Could not find the GDAL library
I have a macbook with the M1 Chip and I'm trying to set up a django project. The project works with Geospatial libraries gdal. I installed gdal with homebrew on version 3.3.1_3 and inside my virtual env version 3.3.1 If I type python manage.py migrate I get an error: django.core.exceptions.ImproperlyConfigured: Cloud not find the GDAL library (tried "gdal", "GDAL", "gdal3.1.0", "gdal3.0.0", "gdal2.4.0", "gdal2.3.0", "gdal2.2.0", "gdal2.1.0"). Is GDAL installed? If it is, try settings GDAL_LIBRARY_PATH in your settings. By pip list shows me GDAL at version 3.1.0. The Django Docs say version 3.3.x is not supported but I cant install a specific gdal version with homebrew. Is there a different solution to get the django project up and running? -

Django file runs from shell but not run but on own
When trying to running a file inside my project, I get the error: django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured.

How to make a POST request inside Django's Test.py with an authenticated user?
I'm trying to find a way to test a POST-request which need an authenticated user in Django. I'm using the login-option as described in the docs here: https://docs.djangoproject.com/en/3.2/topics/testing/tools/#django.test.Client.login And I'm using the client.post method as described here: https://docs.djangoproject.com/en/3.2/topics/testing/tools/#django.test.Client.post However, my response prints as "None" and I'm getting a 403, rather than a 200 as my view should return.

Django admin add entry to specific groups
Hej! I'm looking for a possibility to add entries by different users and groups. In my app there are different users and different groups where one user can belong to multiple groups. The goal is that some of the groups have sensitive data so I only want members of this group to be able to read the entries but some data should be available in multiple groups. It should also be possible to only see some information. (e.g. See the name but not the address) For now I have the decorator @login_required for all my views and @permission_required for a persons_view. Therefore you have to be a registered user to see anything, which is great but not quite enough. I also created groups (via the admin area) but can't filter the data for each model/view. The group either sees the data or they don't. The registration of users is connceted to an already existing ldap system (where those groups are pre-defined. Would be great to use those!) Is there a possibility to add entries only for a special group and view only some of the given information? Thanks for the help! -

Create Django abstract child model refering to the table of the parent model
I have a model (Parent) that has a table in the database (table app1_parent) in a first app (app1). In another app (app2), I would like to add functionnality to this Parent model, but still refer to the existing Parent table (table app1_parent), which is part of the other app (app1). If I create in app2 the Child model that simply inherite from Parent, I end up with two different tables: app1_parent and app2_child I'd like to know if I can create an (abstract ?) child model (Child) that refers to the table of the Parent model, without adding additional field, but adding new methods and properties. (Basically I would want to do the contrary of what abstract tables have been built to do) class Parent(models.Model): my_field = models.CharField(max_length=255) class Child(Parent): def my_method(self): return 'done' class Meta: abstract = True Is there another way to achieve my result? PS: of course, the objective would be not to modify the app1.Parent model and app1.parent table -
