Django's m2m_changed signal on User's groups is not triggered
I created an m2m_changed signal to automatically set is_staff attribute of users when they join/leave a specific group, but the signal is never fired.

I want to show JSON data in my Django template when Django's URL is roaded
I want to show JSON data in my Django template when Django's URL is roaded.

How to import images from media_url to template.html in Django?
Well I am encountering a strange issue in my Django app. My app (in a loop) import an image into the media_url and then it goes to the next page and shows the image and goes back to first page. This was working very well yesterday. Today when I restart the server, the image goes to the media_url as before, but what I see in the next page is not what it is on the media_url and actually it is a picture that was imported before. here is the important part of the code: settings.py: MEDIA_ROOT = 'media//' # I test the MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = 'media//' views.py: def scraping(request): .... template_name = "scraping.html" response2 = {'media_root': Config.MEDIA_ROOT, 'media_url': Config.MEDIA_URL} return render(request, template_name, response2) scraping.html <img src='{{media_url}}/pic.jpg//'> # I also tried {{media_url}}pic.jpg {{media_url}}/pic.jpg/ {{media_url}}//pic.jpg// ... It is surprisingly showing different images for each line Can you help me please? It seems that maybe! the media_url is not updating after each loop. I have no idea! -

Django // How do I need to setup user data management?
I'm working on a pwa with django and I almost done all the front/backend and I'm now facing which might be the last part to put in place (I believe and hope so !) : User Data Management I already had a look at Django's documentation regarding user/group management and I think it is quite logical and understandable however I'm really stuck on how should I implement all of this according to my project ? And especially how should I manage user's data ? Today, the development part is already setup with models/data saving/editing. But there's no user dimension for now, everything created and stored in the database is "general" (I'm using SQLite3 mainly because it was easier to deal with for development and testing but I'm clearly not fixed to it and I can easily readapt parts of the code based on the chosen database and how it work, even more if other database are better adapted to what I am looking for). To give you a bit of context the application should allow anyone to create an account to access the app. When he user is logged on, he/she will be able to arrive on an interface with … -
Optimal Way to Add Dynamic Fields or Preload Initial Values for Django Models
So... I'm working on Django Project in which a question form will be presented to the user. The questions are all yes or no so it will be easy to do that on a database. NOT! for me at least. I've been scouring Google, Django Docs, et al. looking for an answer to this however the only answer I can think of is the one I will be presenting below. GOAL: Make a model class named EmployeeMedicalQuestions in which I will store all the responses sent by a user referencing a One-to-One Relationship with EmployeeProfile. PROBLEM: I have realized that to ask the same questions for all the users, I need to reinitialize the questions for each of them because of the One-to-One Relationship. With my novice experience in Django and Python, I really don't have any idea how to do this 'programmatically'. I also don't want to hard-code the questions (because they might change) as model.BooleanField() one-by-one because I'm too lazy to do that and defeats the purpose of 'dynamic' content. And it's boring. OPTIMAL SOLUTION: I have created a way to overcome this, though by programmatically creating multiple model.BooleanField() variables. Take a look at the code below: models.py … -

I'm having an issue trying to send data with fetch to DJANGO. I want to send some data to django through fetch but when I debug I receive nothing in the post value, do you know what could be happening? This is my fetch call: const defaults = { 'method': 'POST', 'credentials': 'include', 'headers': new Headers({ 'X-CSRFToken': csrf_token, 'Content-Type': 'application/json', 'X-Requested-With': 'XMLHttpRequest' }), data:{'name':'A name'}, dataType:'json' } const response = await fetch (url, defaults) When I debug I get an empty querydict in the request.POST What am I doing wrong?
