Django CBVs: get_queryset() and get_context_data()?
What is the difference between get_queryset() and get_context_data() in a ListView (and what is their relationship). And what gets passed as **kwargs in get_context_data(self, **kwargs) for example in path(' ', SomeViewList.as_view())?

How to reload url in Django to the same page to the same point
I am a beginner in Django and I have been trying to make a social media app where a Post gets a like or a from any other user . Each time when a user adds a comment or likes a post I used forms to change the data in the database. I want the page to reload the fresh data i.e a comment or a like on the post but due to the redirect function the whole page is reloading interrupting my user experience . In simpler terms there are 2 users x and y . y made a 1000 posts and all the posts are available on the profile page of y . x is critic and y asks x to comment the quality of the post for each and every one of the 1000 posts. According to what I wrote in views.py whenever x comments on a post I made a form that takes the content and stores it to the database but because of the redirect after each time he adds a comment on a post the web page is refreshed to the top of the page making x to scroll down all the posts to … -

Duplicate images on docker-compose build. How to properly push two services of docker-compose.yml to Docker hub registry?
I have a docker-compose.yml defined as follows with two services (the database and the app): version: '3' services: db: build: . image: postgres environment: - POSTGRES_DB=postgres - POSTGRES_USER=(adminname) - POSTGRES_PASSWORD=(adminpassword) - CLOUDINARY_URL=(cloudinarykey) app: build: . ports: - "8000:8000" depends_on: - db The reason I have build: . in both services is due to how you can't do docker-compose push unless you have a build in all services. However, this means that both services are referring to the same Dockerfile, which builds the entire app. So after I run docker-compose build and look at the images available I see this: $ docker images REPOSITORY TAG IMAGE ID CREATED SIZE mellon_app latest XXXXXXXXXXXX 27 seconds ago 1.14GB postgres latest XXXXXXXXXXXX 27 seconds ago 1.14GB The IMAGE_ID is the exact same for both images, the size is exactly the same for both images. This makes me think I've definitely done some unnecessary duplication as they're both just running the same Dockerfile. I don't want to take up any unnecessary space, how do I do this properly? This is my Dockerfile: FROM (MY FRIENDS ACCOUNT)/django-npm:latest RUN mkdir usr/src/mprova WORKDIR /usr/src/mprova COPY frontend ./frontend COPY backend ./backend WORKDIR /usr/src/mprova/frontend RUN npm install RUN npm run … -
Apache2 shows default page when I visit the site without 'www' on an android device, but works fine with 'www'
I deployed Django website: www.alahaberry.com on Linode Ubuntu 20.04 LTS. Whenever I try to access it with my computer, it works just fine whether I add www or not. Today my friend tried to check it out from his android device and the apache2 default page appeared. This only happened on android device (or maybe all mobile). I tried with BlueStacks too the same. Without www it shows default apache2 page. Please what could be wrong. I really need your help. Thanks advance. I used letsencrypt to get SSL on it.

Using Django-filter with DRF
I am trying to use django-filter with DRF.

Pip not found in Vagrant's VM with VSCode
I am running a VM with Vagrant to run a basic Django REST API project. I initially created a venv at the VM's home directory at ~/venv, then I installed Django and started the project. All the files and folders are inside /vagrant/ in the VM. It looks something like this when in /: (venv) vagrant@ubuntu-bionic:$ ls / bin dev home initrd.img.old lib64 media opt root sbin srv tmp vagrant vmlinuz boot etc initrd.img lib lost+found mnt proc run snap sys usr var vmlinuz.old Now I have added my a remote via SSH to my VSCode but it initializes in home/vagrant/' which is different than my /vagrant/ folder. Is there a way to change this? Then I also have to select Python interpreter and install pylint but when I try to install it I get: There is no Pip installer available in the selected environment., even though I have pip installed. I am a little confused about how to properly set up the remote on VSCode to run smoothly with a proper interpreter, pylint and everything just as my local machine. Also, I am running python 3.8.3 on my local machine but the remote on VSCode only allows me to … -

With django update a user every second that they are logged in
I'm building a website that will have users that can login and do stuff. But every second that they are logged in I want to decrement a value that is associated to that user(called time_left). Right now I'm thinking of calling a method when logging in that then keeps running continuously till the user logs out. So I call a method in login view called time_update: def login(request): """ View function. In case it is a POST request, the user login form is created and is checked if valid. If it is valid, it is processed checked if user can log in. Otherwise a response with the form is sent. """ if request.user.is_authenticated: return redirect('home-page') if request.method == "POST": form = UserLoginForm(request, data=request.POST) if form.is_valid(): email = form.cleaned_data.get('email') password = form.cleaned_data.get('password') user = authenticate(email=email, password=password) if user is not None: if user.is_active: auth_login(request, user) time_update(user.email) else: print("user is not authenticated") return redirect('home-page') # user is redirected to dashboard else: form = UserLoginForm() return render(request, 'users/login.html', {'form': form}) But I'm kinda stuck on what to with this time_update method that should decrement the time_left value every second. Especially for multiple users that are logged in at the same time. Anyone any … -
