Unable to create a custom admin template url, getting errors Template errors & creating custom admin site errors
I am using this blog: https://medium.com/@adriennedomingus/adding-custom-views-or-templates-to-django-admin-740640cc6d42 Unable to make a custom template view in the Django Admin.

Django Makemigrations returns ModuleNotFoundError: with module name suffixed by 'django'
I've been following the Python Crash Course 2e tutorial. I encountered a problem with makemigrations function from Django chapter(18). I created first app using startapp, and then tried to call makemigrations. It returns ModuleNotFoundError but it gives an app name suffixed by 'django'. What I did was: python -m venv ll_env ll_env\Scripts\activate pip install django (installed asgiref-3.2.3 django-3.0.3 pytz-2019.3 sqlparse-0.3.1) django-admin startproject learning_log . python manage.py migrate python manage.py runserver This part runs smoothly, webserver works, everything is great. Then I opened another terminal(on project level), and typed: ll_env\Scripts\activate python manage.py startapp learning_logs <edited settings.py to include 'learning_logs'> python manage.py makemigrations learning_logs As a result makemigrations returns this traceback: Traceback (most recent call last): File "manage.py", line 21, in <module> main() File "manage.py", line 17, in main execute_from_command_line(sys.argv) File "C:\Users\Admin\PycharmProjects\djangoproj\ll_env\lib\site-packages\django\core\management\__init__.py", line 401, in execute_from_command_line utility.execute() File "C:\Users\Admin\PycharmProjects\djangoproj\ll_env\lib\site-packages\django\core\management\__init__.py", line 377, in execute django.setup() File "C:\Users\Admin\PycharmProjects\djangoproj\ll_env\lib\site-packages\django\__init__.py", line 24, in setup apps.populate(settings.INSTALLED_APPS) File "C:\Users\Admin\PycharmProjects\djangoproj\ll_env\lib\site-packages\django\apps\registry.py", line 91, in populate app_config = AppConfig.create(entry) File "C:\Users\Admin\PycharmProjects\djangoproj\ll_env\lib\site-packages\django\apps\config.py", line 116, in create mod = import_module(mod_path) File "C:\Users\Admin\AppData\Local\Programs\Python\Python38-32\lib\importlib\__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1014, in _gcd_import File "<frozen importlib._bootstrap>", line 991, in _find_and_load File "<frozen importlib._bootstrap>", line 961, in _find_and_load_unlocked File "<frozen … -

Django Rest Framework: Pickle Response
What I'm trying to do is build a custom version of cache_page where I have more control over the cache key, but I'm getting stuck with even the basic caching of my response: from django.core.cache import cache class BaseViewSet(viewsets.GenericViewSet): queryset = models.Items.objects.all() def get_queryset(self): return models.Items.objects.all() def list(self, request, **kwargs): response = Response({}) cache.set('test', response, 10) return response Where the relevant parts of my settings.py are setup as: REST_FRAMEWORK = { 'DEFAULT_RENDERER_CLASSES': [ 'rest_framework.renderers.JSONRenderer', ], 'DEFAULT_VERSIONING_CLASS': 'rest_framework.versioning.NamespaceVersioning' } CACHES = { "default": { "BACKEND": "django_redis.cache.RedisCache", "LOCATION": f"redis://127.0.0.1:6729/1", }, } When I try to call the endpoint I get: django.template.response.ContentNotRenderedError: The response content must be rendered before it can be pickled. Then if I change the line to: cache.set('test', response.render(), 10) I get: AssertionError: .accepted_renderer not set on Response Despite the fact that the API call itself works fine without the caching. cache_page actually works fine, so I know it's possible to cache the response, but I can't figure out what I'm missing. -

Django - Correct method of consuming my own REST API internally in the views.py?
I created a Django REST API using serializers, viewsets and routers.

I can get my items using: Item.objects.filter(available=True) Which gives me the result pretty much instantly but I'm writing all the queries twice (once in my API and once in my views.py) Is there a better way of doing this like calling the viewset class directly and getting … -

How to set boolean fields of all but one from the multiple Django formset rows during save
I am updating multiple records from a single form using Django inline formset factory. Multiple number of rows of data are expected to be created by users at once. My model is: class Tariff(models.Model): tariff_item = models.AutoField(primary_key=True, verbose_name='Tariff Item') eff_date = models.DateField(null=True, verbose_name='Eff date') tariff_rate = models.DecimalField(max_digits=7, decimal_places=2, null=True, blank=True, default=0.00, ...) tariff_is_past = models.BooleanField(default=False) As stated above there can be more than one formset row when the user saves it. The only caveat being: All the rows with data MUST be marked with BOOLEAN FIELD "tariff_is_past" to True, except the last. Presently the boolean fields are being marked manually. As the rows are as yet not part of the table I can not run a query on the rows and set the boolean field to True. Can the scenario be addressed? Can I set Boolean field "tariff_is_past" for all but the last (ordered on the date field "eff_date") row?
