Data that's been sent from client is not valid for my django-rest api
Here is what React client is using to send user sign-up data(to be stored in the database): fetch('http://127.0.0.1:8000/api/user', { 'method': 'POST', 'headers': { 'Accept': 'application/json', 'Content-Type': 'application/json', 'X-CSRF-TOKEN': csrfToken, }, 'body': JSON.stringify(data), }) Here is the data that is being sent: username: ["palash"] contact: ["singhpalash0@example.com"] dob: ["2021-04-08"] password: ["password"] Here is the response I'm getting back from the server(along with a status code of 400) contact: ["Not a valid string."] dob: ["date has wrong format.

user not staying logged in after changes to user password and username
I have made a django view and form to update username and password and it does what it's meant to do, but I have trouble with the user staying logged in after the changes are done: Here's my view logic: class UserUpdateView(LoginRequiredMixin, UpdateView): model = User form_class = UserUpdateForm template_name = 'todo_list/userupdate.html' success_url = reverse_lazy("tasks") def get_object(self, queryset=None): return self.request.user def form_valid(self, form): user = form.save() if user is not None: login(self.request, user) return super(UserUpdateView, self).form_valid(form) As you can see the idea is for the user to be logged in after the changes are made, which doesn't happen. The user is automatically logged out and I don't know why. Any help is much appreciated. -

Access via URL instead IP address to local dockerized Django project
I got a small django project wich runs within a docker container and is locally only (no need to expose it to the whole internet, just my office), but since it's a coporate project I want to give the persons who use it the possibility to access it using an URL (maybe something like "projectName.corporateWhereIWork.org") instead host machine ip address:port. Being honest, I have already read and search about terms like "reverse-proxy", "companion", "ACME", "DNS" but these are concepts that are very difficult for me to understand and I don't know how to configure nginx properly. This is my nginx config file (see it's a very simple configuration): client_max_body_size 10M; upstream project { ip_hash; server project:8000; } server { location /static/ { autoindex on; alias /src/static/; } location /media/ { autoindex on; alias /src/media/; } location / { proxy_pass http://project/; } listen 8000; server_name localhost; } And my django image entry point: CMD ["sh", "-c", "python manage.py collectstatic --no-input; python manage.py migrate; gunicorn project.wsgi -b 0.0.0.0:8000"] Both containers expose to same port. -
Why my website is rendered correctly on some phones and on others not, using the same browser?
I am trying to build my first webiste and I encountered a big problem with the rendering on different devices. I used Django framework Here is my website, deployed on pythonanywhere. It is a basic one, for educational purposes. http://tudorilade.pythonanywhere.com/ When I try to access it from a Xiaomi phone, for instance on Chrome, I have rendering problems. My website does not want to apply the CSS to the page. I sent my website to different friends, and they opened it with Chrome: 1/3 of them had rendering problems. However, if I use other Browser, or I open it, using the default browser provided by facebook messenger, it looks just fine. I cannot understand why some can have an user-friendly navigation on my website, and others not. I think that it is a phone problem, and my media query does not find the width of the used device. NOTE: if I use inspect element on the browser and I try different sizes in the range of 280px - 726 px, it looks good. @media screen and (max-width:726px) { ...... all the responsive CSS code } And this I have on index page: <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> If somebody … -

Is python multiprocessing( not multi-threading ) possible with Django running on Windows
For python multiprocessing, you have to enter a if __name__ == '__main__' check for reasons well explained elsewhere on stackoverflow when running on Windows. How do you overcome this limitation in Django where you are several layers away from the __main__ module. e.g. To run and execute my own command, the flow is: manage.py --> calls mycommand.py --> calls function in anothermodule.py( which carries out the actual work - this is where the code for multiprocessing should go). Neither mycommand.py or anothermodule.py will ever test true for if __name__ == '__main__; it will only be true in manage.py. So is multiprocessing simply not a viable option in Django? How do others get around this limitation? -

Django Python annotate ManyToMany Relationship with additional information
my problem is the following. I have two models in the database, which I link together using a ManyToMany relationship. For the admin page I currently use "admin.TabularInline" to bind different objects to one via the graphic. I still want to specify an order in the connections, preferably numbers which represent an order for processing. A bit more figuratively described I have the model "Survey" and the model "SurveyQuestion". So I connect many SurveyQuestions with the Survey. But I can't specify an order, because I don't have an additional field for it. It is not known before how many questions will be in a survey. Nor is it known which questions will be inserted. Usually they are built during the compilation of the survey and may be used later for another survey. I am grateful for every tip! -
