Django Admin wont allow me to allocate permissions to Users or Groups
I am using django 1.8.6 and have a new application created in a virtualenv using python manage.py startproject. I have set up my INSTALLED APPS and my database settings (postgresql) and I have run migrate to create the backend. So far all seems fine. I then created a superuser using the createsuperuser command and that all seemed to go fine too. My admin.py file is in place and the content of which is as follows: from django.contrib import admin from django.contrib.admin import AdminSite from myapp.models import mymodel Class mymodelAdmin(admin.ModelAdmin): list_display = {col1, col2, col3} admin.site.register(mymodel, mymodelAdmin) All what appears to be fairly simple standard stuff, so far so good. I'm using apache to render my webpages and having configured my virtualhost stuff I can happily log in to my admin page and see everything I have registered plus the default django admin stuff. I can create a new user with no problem and I can create a new Group with no problem. Where I am running into trouble is I ma not able to assign any standard permissions to with my new user or my group. I can see the list of permissions from my database with no problem but … -

Correctly wiring volumes for serving static files using nginx and Django
I am having issues correctly linking up the different parts of the application to correctly serve static files to users. This is the scenario: I have an existing Django website that I want to "dockerize". My problem is probably that I'm very confused as to how volumes/containers work, and I've tried to read up about it but I cannot get it working. I have created the following directory structure: project/ nginx/ Dockerfile nginx.conf web/ << django website >> Dockerfile docker-compose.yml project/docker-compose.yml deploys the Django application and, via Gunicorn, makes it available at 0.0.0.0:8080, albeit without being able to load static files. The project/web/Dockerfile runs a collectstatic operation on the Django app and collects all static files in /usr/src/app/static_files. By running a bash shell on the web container I have confirmed that these files are indeed here. version: '3.3' services: web: restart: always build: ./web expose: - "8080" ports: - "8080:8080" volumes: ## something goes here? command: /usr/local/bin/gunicorn wsgi:application --workers 2 --bind 0.0.0.0:8080 depends_on: - postgres nginx: restart: always build: ./nginx ports: - "80:80" volumes: ### something goes here? depends_on: - web postgres: image: postgres:9.2 restart: always volumes: - pgdata:/var/lib/postgresql/data ports: - "5432:5432" volumes: pgdata: How do I modify the docker-compose … -
creating relationship between two apps in django
I have a post and a category app in my django project. I have user authentication and users can create categories as well as posts. I am at a point where I am out of ideas and help would be appreciated. I want users to be able to reference only their own category and create posts in their categories not in another persons own. That is if a user creates more that one category he should be able to select from the list of his created category and not see another persons own. category model class Category(models.Model): name = models.CharField(max_length = 120) slug = models.SlugField(unique= True) timestamp = models.DateTimeField(auto_now=False, auto_now_add=True) post model class Post(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, default=1,related_name='posts_created') #blank=True, null=True) title = models.CharField(max_length = 120) slug = models.SlugField(unique= True) category = models.ForeignKey(Category, on_delete=models.CASCADE, related_name='category_created', null= True) addition codes would be provided immediately on request.

Tables referencing each other with One-To-Many relationship

Django Rest Framework JWT "Authentication credentials were not provided."}
I am trying to write a simple API that uses JWT tokens to authenticate. My settings.py: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'rest_framework', ] REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.IsAuthenticated', 'rest_framework.permissions.IsAdminUser' ), 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework_jwt.authentication.JSONWebTokenAuthentication', 'rest_framework.authentication.SessionAuthentication', 'rest_framework.authentication.BasicAuthentication', ), 'PAGE_SIZE': 10 } And my View looks like this: class ExampleView(APIView): permission_classes = (IsAuthenticated,) authentication_classes = (JSONWebTokenAuthentication,) def get(self, request, format=None): return JsonResponse({"username":str(request.user)}) Which really does nothing, but I don't even get there. I have registered the JWT Token provider as in the documentation with url(r'^api-token-auth/', obtain_jwt_token) and I receive a token when I call this endpoint. However, when I then make a request against my APIView (which contains the header Authorization: JWT <my_token> I always receive the following error: [Response]: 403 [Data]: {"detail":"Authentication credentials were not provided."} What am I missing?
