Django: AuthStateMissing at /oauth/complete/google-oauth2/
I am using social-auth-app-django for GoogleOauth2 authentication. It works fine for all users but in case of django admin it gives me following error: AuthStateMissing at /oauth/complete/google-oauth2/ Session value state missing.

How do I pass URLs from my Django rest API to the Flutter front-end
I am very new to Django REST framework and Flutter so if the solution to this is very simple I apologies. I am trying to pass the URLs from my Django back-end to the Flutter front-end. I feel like the solution is a urls.dart file where I can store all the URLs from Django. However, I have no idea what the code for this file would look like. Here are the URLs that I need passed over urlpatterns = [ path('', views.getRoutes), path('notes/',views.getNotes), path('notes/create/', views.createNote), path('notes/<str:pk>/update/', views.updateNote), path('notes/<str:pk>/delete/', views.deleteNote), path('notes/<str:pk>/',views.getNote), ] It is not deployed so I am using localhost. When I implement the URLs into the flutter code I want them to look something like this: .put(updateUrl(widget.id), body: {'body': controller.text}); widget.client.post(createUrl, body: {'body': controller.text}); Any help would be much appreciated. -

How to access a field from a ForeignKey on a Queryset in django?
This is my models.py: class Computer(models.Model): name = models.CharField(max_length=40) ip = models.GenericIPAddressField(blank=True, null=True, unique=True) class Template(models.Model): data = models.JSONField(...) computer = models.ForeignKey(Computer,on_delete=models.CASCADE) When I delete a template object, from django admin, I need to make an API request, so I edited the delete() method. That works fine. But this doesn't work for the multiple delete option in django admin. I already know that I have to edit the delete_queryset() in admin.py. What I need to know is how to get the field IP from Computer from the queryset that the delete_queryset() method returns. When I do the following in admin.py: class TemplateAdmin(admin.ModelAdmin): def delete_queryset(self,request,queryset): print(queryset) print(queryset.values('computer')) ... And I try to delete multiple template objects (A,B and C) I get the following response: <QuerySet [<Template: A>, Template: B>, Template: C>]> <QuerySet [{'computer': 22}, {'computer': 21}, {'computer': 21}]> 22 and 21 are the computer_id referenced by the ForeignKey in A,B and C. The question is, how do I access the IP field from those computers so that I can make the API request in the delete_queryset() method? -

Picking database in django
I am developing a patient tracking system. to summarize. I need a database in the backend where we create a flexible schema (will evolve over time) for keeping track of health related data. I have some of the fields I want in it now. also i will develop front-end portal that people can access themselves or be access by an admin where we will ask questions that fill those fields. That front-end will also display to the user or the admin a summary of those datapoints. Can anyone tell me does postgresql can solve this problem or should i choose mongoDB? i am so sorry for posting without code, actually i tried of making decision which one should i choose. -

Async Class Based Views in Django

Should I a create a separated model/table to organize info?
Supposing that I have a group of data, such as Payment data, like status, amount, external id and etc, and the actual model that this data is related: Order, should I create one model for each, such as: class Product external_id = models.IntegerField() ... class Order payment = models.ForeignKey(Product) Or should I just put the Product data directly into Order fields, to avoid a new table creation? Note: the example is in django, but I think that it should apply for all database designing cases. -

How to have a Python Django map with a satellite view using from django.contrib.gis.db import models?

Django Templates vs React - Already started down the templates route
I'm currently in the process of learning Django to make a web application for my workplace. I initially had the thought of just learning Django first to get the hang of it, then once I had the core logic in place I would then move over to a React for the UI (also need to learn how to use React), instead of templates. I'm now at the point where I could switch, but I've now only just discovered that I should be developing the backend with the Django REST framework to provide APIs for React (and other front ends). Is this something I can easily transfer to? Or is there a way to use React with my existing Django setup? I'm on a slightly tight timeframe and don't exactly need the core features of React right now. Is it better to get the main web application online sooner with Templates (continuing development down that route) or transition now to React and the REST API and finish the rest of the features after? Will it become too big of a task down the track to transition? -
