Getting an invalid JWT token when I try to register a django user

Get image full url on Django Channel Response
I have created a socket with Django channels that return the serialized data of Category Object. But in the response, there is no full URL(the IP address is not there). This problem is similar to this question Django serializer Imagefield to get full URL. The difference is that I am calling the Serializer from a Consumer(Django Channels). Whereas in the link, Serializer is called from a View. In a Consumer, there is no request object as mentioned in the solution. The Django Channels says that scope in Consumers is similar to request in Views. So how can I get the full image url in this case? -

Django base.models.Post.DoesNotExist
I am very new to django. I have followed the steps from a video on youtube on how to create a simple blog. Basically, I have a portfolio main page that displays several things including the latest blogs. It all works well. I can see the latest posts on the main page. I can also click in each of them and they open up fine. However, now, I want to create a new page (blog.html) that will hold all the posts. I created a blog.html and did the necessary settings in views.py and urls.py. However, for some reason I get an error when trying to access localhost/blog/ This is my urls.py: urlpatterns = [ path('', views.home, name='home'), path('work/', views.work, name='work'), path('<slug:slug>/', views.post_detail, name='post_detail'), path('blog/', views.blog, name='blog'), ] Here views.py: def home(request): posts = Post.objects.all() return render(request, 'home.html', {'posts': posts}) def post_detail(request, slug): post = Post.objects.get(slug=slug) return render(request, 'post_detail.html', {'post': post}) def blog(request): posts = Post.objects.all() return render(request, 'blog.html', {'posts': posts}) And lastly the error: Internal Server Error: /blog/ Traceback (most recent call last): File "C:\Users\frank\Anaconda3\envs\djangoenv\lib\site-packages\django\core\handlers\exception.py", line 34, in inner response = get_response(request) File "C:\Users\frank\Anaconda3\envs\djangoenv\lib\site-packages\django\core\handlers\base.py", line 115, in _get_response response = self.process_exception_by_middleware(e, request) File "C:\Users\frank\Anaconda3\envs\djangoenv\lib\site-packages\django\core\handlers\base.py", line 113, in _get_response response = … -
Translate many-to-many relationship in database ER diagram to Django model
I want to represent users and teams in Django application. Each user can be member of zero or more teams. This is ER diagram of database that I came up with: Following this design, I'd like to implement Django models: class Team(models.Model): name = models.CharField() created_at = models.DateTimeField(auto_now_add=True) class UserIsMemmberOfTeam(models.model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) team = models.ForeignKey(Team, on_delete=models.CASCADE) But this aproach feels not fitted for Django ORM. I've also thought about: from django.db import models from django.conf import settings class Team(models.Model): name = models.CharField() created_at = models.DateTimeField(auto_now_add=True) members = models.ManyToManyField(settings.AUTH_USER_MODEL) There is new field members, but I think, under the hood, database looks similar to the diagram above. Which aproach is better? Maybe each of them has its own perks? But what if: I'd like to assign each team member some role(s) in given team. In ER diagram, I would design it like that: How should I represent it in Django? This time it looks like I can't use the second approach from above, because there is no model representing member. Should I make MemberHasRole model, or should I make Member model that has roles (many-to-many) field? -
