python django webapp packaging sdist
When I run python setup.py sdist in my project directory and check the contents with tar --list -f .\dist\my_project_name-1.0.tar.gz I see one important python file (manage.py) and a couple of directories templates, which contains .html files, and static, containing .css files, are missing. I've looked at many questions: Q1 Q2 Q3 Q4 but adding a MANIFEST.in or adding the following lines to my setup.py didn't change anything. And what about my manage.py? Shouldn't python files be included by default with sdist? include_package_data=True, data_files=[('templates','my_app/templates/my_app/*.html']), ('static', ['my_app/static/my_app/static/css/*.css'])] Also, I get the same exact result with python setup.py sdist bdist_wheel (although I'm not sure what's the difference with the two commands). -
flow of code from view to serializer class in django rest framework
I am trying to understand the code flow in Django rest framework from view class to serializer class. Like we know if we create an object of a class, the class gets instantiate with that object. And if there are other functions inside that class, we can call that function using the object we just created followed by dot and that function name. It looks something like this. class Person: def __init__(self, name, address): self.name = name self.address = address def details(self): print (f"My name is {self.name} and I live in {self.address}") obj1 = Person("John","London") obj1.details() For example in the above code, when we run obj1= .... , the person class will instantiate with values name and address. And then we can call the details function using the class object that we just created obj1. Now in Django Rest, class LeadsView(APIView): permission_classes = [IsAuthenticated] def put(self, request, pk=None, *args, **kwargs): id = pk abc = Lead.objects.get(id=id) print("before serializer") serializer = LeadSerializer(abc,data=request.data) if serializer.is_valid(): print("after serializer validation") serializer.save() print("after save") return Response({ "message": "Coupon hase been updated", "data": serializer.data }, status=status.HTTP_200_OK) return Response(serializer.data) class Leadserializer(serializers.ModelSerializer): class Meta: model = Lead fields = 'all' def update(self,instance,validated_data): .......... print("iam inside the serializer class") … -
How to fix "assess has been blocked by CORS policy: No 'Access-Control-Allow-Origin' in react
I have a web application with react frontend and django backend. Some of the APIs from the backend are being blocked by cors policy whereas others are not. For example, The API to fetch blog posts const res = await axios.get(`${process.env.REACT_APP_API_URL}/blog/posts`) is returning data but the API for individual posts const res = await axios.get(`${process.env.REACT_APP_API_URL}/blog/${slug}`); is blocked. The register and login APIs are blocked too. I have added the domain to the list of allowed url in settings.py but that didn't solve the issue. The error I'm getting in the detail page is: undefined:1 Access to XMLHttpRequest at 'https://.api.example.co/blog/undefined' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. When I use Postman to test the API's everything works properly. But In react app it's only the API that list posts or items that are returning data, others are blocked. Why such behaviour, and how do I fix it? -

Unable to do migrations using docker.yml file- django+postgres
I get the following error while I try to run my django project on docker. relation "DBTable" does not exist at character 218 I figured out it was because the migrations weren't being applied. So I changed my Dockerfile as follows to make migrations before starting the server: FROM python:3.7 WORKDIR /ServerCode2/ COPY . /ServerCode2/ RUN pip install -r req.txt EXPOSE 8000 CMD ["python", "manage.py", "makemigrations" ] CMD ["python", "manage.py", "migrate" ] CMD ["python", "manage.py", "runserver", "--noreload" ] Below is my docker-compose.yml file version: '3.7' services: server: build: context: ./Appname dockerfile: Dockerfile image: serverimgtest1 container_name: servercontest1 ports: - 8000:8000 links: - db:db depends_on: - db db: image: postgres environment: POSTGRES_DB: "DBname" POSTGRES_HOST_AUTH_METHOD: "trust" ports: - 5432:5432 client: build: context: ./appfrontend dockerfile: Dockerfile image: clientimgtest1 container_name: clientcontest1 depends_on: - server ports: - 3000:3000 However, I still see the error which says the relation does not exist.

I've a problem with django admin login with abstract superuser
I am developing a separate author abstract model for my blog site. The authors in this abstract model connect to my post application, another application of mine, with a foreign key and create the author-post relationship.

Directly render html page on specific element without scroll (Django/JavaScript)
My question is about controlling page scrolling/anchor targets while using Django and Bootstrap. I have a Django project styled using Bootstrap. Information is rendered sequentially on a page. New information is added to the bottom of the page each time a user presses a button. This is achieved through loading all the information into a dictionary, but only rendering specific sections of it depending on a variable count which stores how far the user is through the case. When the button is pressed, information is passed to a view which checks its integrity and if acceptable increments a count variable and redirects the user back to the original page. The original page now shows new information because of the incremented count variable. I am trying to use anchors with the URL redirect to ensure the page loads on the new information. These anchors work, but the page is loading from the top each time a user presses the button to advance and then the page scrolls down. Ideally the page would load directly on the new information or reload where the user clicked submit and then scroll to the new information. A section of the view to demonstrate the current … -

Access content for Anonymous and logedIn User
How best can I access content while the user is not logged in. For example, I have the View which handles both Listing and posting blog posts , though I want someone to access content even without being logged In, though the person shouldn't create a blog post, unless logged In. Below is my current implementation : class PostList(generics.ListCreateAPIView): """Blog post lists""" queryset = Post.objects.all() serializer_class = serializers.PostSerializer authentication_classes = (JWTAuthentication,) permission_classes = [permissions.IsAuthenticatedOrReadOnly] def post(self, request, *args, **kwargs): serializer = self.serializer_class(data=request.data, context=request) if serializer.is_valid(): serializer.save() return response.Response(serializer.data, status=status.HTTP_201_CREATED, ) return response.Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) So how best can I play with these lines : authentication_classes = (JWTAuthentication,) permission_classes = [permissions.IsAuthenticatedOrReadOnly] because when I remove this line : authentication_classes = (JWTAuthentication,) I can access the lists of blogs, though I will need an endpoint of creating a blog posts to be protected, how best can this be achieved -

Extra tables in Django's admin group permission list
I have run a few fake migrations yesterday and also renamed a few tables of my database direcly yesterday due to foreign key constraints and other similar errors Django kept throwing at me after renaming some models. I know this is not standard procedure and it's prone to messing up things. It did solve everything for me though, without the need of wiping out the database, as I was almost resolved to do. Anyway, as I said, all is working great, expect for the list shown in the 'available permissions' in the Group management. The following (and other) tables are not in the database, and indeed are not even prepended with the applications's name: Where are those sourced from? How can I get rid of them? -

Using a model as a source for a PK for diffrent model?
So if I have a simple model that I want as a source of my PK like so: class PostCreation(models.Model): pk = models.AutoField(primary_key=True) post = models.OneToOneField(Post, on_delete=models.CASCADE) What I want to do is create a PK of a blog post before the post has been created. My reasoning is I want the images/files I upload to be in a format of /media/blogPK/files So my Post will have a id/PK field set from the PostCreation class above And the Pseudo code is below: id = PostCreation() FileField(upload_to='{}{}{}'.format(id, '/', files)) But how can I create the PK first and then pass it to my Post model and then set the Post is/pk to that of PostCreation? I's going to be using ModelForm to output the fields for the Post content, Description/Date etc so when I goto visit that view I want the pk/id already made even if the user does submit the content of the Post model. How can I do this? Is it possible? Thx -
