Django and MongoDB Error - REALLY WANT TO KNOW
This is a problem with Django connecting to MongoDB I'm building a Django project. And I want to connect my project to MongoDB. But I have some problem. It is really stressful.

How to fetch data at the moment the database updates, without refreshing the page, in Django?
In a web application that I'm building using Django, there is a filed in the main page that fetches a price float from the database and shows it, and I need it to be updated every time that the source price (in the database) gets updated, or within some seconds. And I need that to be without refreshing the page, kind of live you can say. Is there any possible way to reach this without using Django channels, e.g. by using JavaScript or anything else? -

Why changes made in Wagtail's Editor only appear with a delay in the backend (although can be seen in front tend)?
For several months now, when I edit a Page in the Editor of Wagtail and the click "Save", these changes sometimes (often at certain times) disappear fron the Editor. I can see it because when I edit content, I immediately go check the result in frontend and go back to the Editor to edit mistakes for example. In thoses situations, I can see the right content in front end, but not in the back end. I eventually discovered that I need to wait, and after a few minutes at most, the changes appear back in the Editor. Sometimes, if I make successive editions, some of them will appear first, and then the other. Simple example : I add a picture in a blog post, click Save or Publish. I can see the picture in front end, but when I come back to edit this page in back end, the picture is not there anymore. If I wait a little (either come back or just wait and refreh the page in the Editor), the picture will (re)appear in the Editor. Note that the CMS seems to really save the changes because I can see them in front end and in the … -
Django 4.2: Formset "This field is required"
Basic idea: Have a custom database table with only 2 text fields. It will never be updated by the user! Allow the user to select records via checkboxes. The selected records only influence the file that is being served later by the server. This is my models.py: class Person(models.Model): first_name = models.CharField(max_length=200) last_name = models.CharField(max_length=200) I've created a custom non-model-form, derived from forms.Form only, because I will never use the user input to update the database table. All I need is some boolean information from the user. Here's forms.py: class PersonForm(forms.Form): first_name = forms.CharField() last_name = forms.CharField() selected = forms.BooleanField() PersonFormset = forms.formset_factory(PersonForm, extra=0) When the user calls the GET-view, he will see all people in the table and can select some via the checkboxes (notice: form has an additional boolean field). This is the GET-part of my views.py: obj = Person.objects.all().values() forms = PersonFormset(initial=obj) return render(request, 'myapp/mytemplate.html', {'formset': forms}) Everything works fine and displays correctly inside my HTML table. But then the POST fails. Here's the POST-part of my views.py: forms = PersonFormset(request.POST) The forms.is_valid() function returns false and all the error messages state 'This field is required' for all fields of all forms. For example forms[0]['first_name'].value() is None … -

next-auth and django rest framework - how should I fetch user data after JWT authentication?
I'm building an app that uses django rest framework and simplejwt to authorize the users. I'm having trouble understanding what should be the optimal way of fetching user data after the user logs in and JWT is provided. Let's say I'd want to display the user name and email on the navigation bar. Should I: a) add the user name and email to the JWT response (not encoded)? b) after getting the JWT, use it to fetch the user data? As of now, my JWT (/api/auth/) endpoint response looks something like this: { "refresh": "refresh_token", "access": "access_token" } And here's an example of the decoded access token: decoded access token I thought that perhaps next-auth decodes the JWT response and pulls the user data from there. -

How do I stop Django from logging PermissionDenied exceptions?
My custom middleware raises a PermissionDenied exception in certain cases to return a 403 response to the client. I believe this is the "correct" way to do this. Unfortunately it also logs the exception with a traceback every time this happens, even with DEBUG set to False. 2023-05-08 10:27:25,293 WARNING django.request Forbidden (Permission denied): / Traceback (most recent call last): File "/opt/project/env/lib/python3.9/site-packages/django/core/handlers/exception.py", line 55, in inner response = get_response(request) File "/opt/project/myapp/middleware.py", line 112, in call raise PermissionDenied django.core.exceptions.PermissionDenied I don't care about these exceptions.

Django template variables rendered after 403
I have an HTML template which will render button depending on context variable. <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <form method="post"> {% csrf_token %} <button type="submit">{{ number }}</button> </form> </body> </html> After passing "if" check for numbers greater than 400, the function should return response 403 and stop. But in my case it only ignores a template and still renders a context variable. def run_script(request, number): if number > 400: return HttpResponseForbidden() context = {'number': number} return render(request, "mainapp/number.html", context) The only solution I found is so set the rendered value to null in the "if" statement if number > 400: number = None return HttpResponseForbidden() This way I get proper response 403, but I dont like this method since it requires changing every variable, when multiple provided and doesn't look like a proper implementation. Any suggestion how to properly stop execution on response 403? -
