Django " ImproperlyConfigured:"
I have created a blog with django by following some book. The django website works but the terminal keeps on showing this message if i try to interpret the code on spyder(setting.py, models.py) ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. Here ImproperlyConfigured: You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings the solution which was given for this was: set DJANGO_SETTINGS_MODULE=mysite.settings as in the documentation for django. However if i stop the server and restart it after running the code i am still getting the same error. Could you please advise what setting it is referring to which are not configured? This is perticularly odd because it prints out the same error message if I run this help(models.DateTimeField) -

Display SQL table with primary key pair in Django admin
How can I display an SQL table that has a primary key pair as an unmanaged table in Django admin? More details: I have a Django project running in docker that is sharing a Postgresql DB with another program in another docker container.

How to create a Django dropdown form using forms.py without a model?

Getting Field 'None' expected a number but got 'update'. when using UpdateView in Django
I am using UpdateView for my update page, but I get this error: Field 'None' expected a number but got 'update'. my urls.py looks like this: path('post/<pk>/update/', PostUpdateView.as_view(), name='post_update'), Everything works fine if I change my update URL to anything other than "post". For example, this works fine: path('abcxyz/<pk>/update/', PostUpdateView.as_view(), name='post_update'), I would like to use the word "post" in URL, because i also use it in the other URLs and they work just fine (except for delete view, which gives me the same error). Is there any way to fix this error without changing the URL? Note: It has worked before, but it broke at some point when I was trying to use django-PWA. I'm not sure if this is related though. Thank you for your help! -

Best way to design API with Django rest framework working asynchronously
