How To Host Multiple Vite Apps in One Django Project?
Problem How would I host multiple vite applications built on different architectures (vanilla and react) in the same Dango instance? I have a a django app that had a pre-es6 javascript front end that I converted to a vite vanilla javascript application, delivered using the wonderful Django-Vite plugin. The app is working fine, but now there's a request to add a new react-based vite app to the existing django project, and django-vite does not support hosting multiple vite applications out of the box. Thoughts Have a single vite app that would redirect to another vite app, one of the two I need to build (not sure how this would work) Merge both vite manifest.json files together at build time to be served from a single location (don't know what the ramifications would be) ~Host a NextJS app external to Django~ (insert unicorns and rainbows here) <-- Can't do this one because leadership thinks integration would be more effort than it's worth Thanks! -

Django template - for look iterate over variable
I am looking for a way to iterate over variable in django template. In template I do not know how to assign variable in for loop. In get_context_date of ListView i am assigning data of two files to two vars like: context[f"{t_name}_header"] = db_oper context[f"{t_name}_body"] = db_header Context is generated for two files which results with vars like: context["test1_header"] context["test1_body"] context["test2_header"] context["test2_body"]` test1 and test2 are names populated from model. I can access them with object_list in template. In template html file I would like to iterate over context like: {% for object in object_list %} {% for item in object.name|add:"_header" %} ...do stuff {% endfor %} {% for item in object.name|add:"_body" %} ...do stuff {% endfor %} {% endfor %}` In result in html template I got nothing. How to properly filter variable in for loop so it could go thru eq. test1_header ? -
user login problem after upgrading to Django 4.2 from Django 2.0
I upgraded my django project from 2.0 to 4.2 and now I am getting the following error on one page where I am using the login() function to log the user in. Error: The request's session was deleted before the request completed. The user may have logged out in a concurrent request, for example. This was working without any problems in django 2.0 and I have been trying to find out the problem for hours but can't find anything related to it. I will attach the code below: def handle_no_permission(self): if self.request.user.is_authenticated and not self.test_func() and not self.is_source_email(): self.raise_exception = True if all(x in self.request.GET.keys() for x in ["token", "source"]): if self.is_source_email(): token_from_url = self.request.GET.get("token") deficiency_id = self.kwargs.get('deficiency_id') try: login_token = ProviderLoginToken.objects.get(key=token_from_url, deficiency_id=deficiency_id) if login_token.active: user = login_token.provider.user user.backend = "django.contrib.auth.backends.ModelBackend" print('BEFORE', self.request.user.is_authenticated) login(self.request, user, backend=user.backend) print('AFTER', self.request.user.is_authenticated) else: return render(self.request, "500_invalid_quick_amend_link.html") except ProviderLoginToken.DoesNotExist: return render(self.request, "500_invalid_quick_amend_link.html") return super().handle_no_permission() The user is able to still login because is_authenticated() returns False before and True after the login() function. -
Associating User with AWS Credentials in Django REST Framework | How to Store AWS Credentials per User in Django REST Framework
I'm building a Django API where users can input their AWS credentials, which are then verified and stored in the backend. I want to associate each set of credentials with the user who inputted them, and I want to use a unique UUID for each user.

Multible objects creation in Django Admin Panel
My desire is to create several objects in one django admin-panel creation window. Look: class ExampleModel(models.Model) field1 = models.CharField() field2 = models.CharField() field3 = models.CharField() date = models.DateField() In this case most important part is date, Often I create objects in admin-panel, where first 3 field are the same(at the moment of creation) and only date must be unique. So I wanna integrate some widget where I can choose all dates that i need, and by clicking submit button create number of objects. I found package named django-bulk-admin, which can solve my task. But it is not supported in Django 3. Also ChatGPT suggested me to create some actions in Admin class definition, but it is not works. I guess solution is redefine action of AdminForm of this model, but I don't know how? -

Django ORM query taking very long but Raw query runs as expected
I have a simple get query key = TenantKey.objects.get(pk=api_key) When I'm running a load test, for many requests the above query is taking multiple seconds (max 15s) which is very strange. So I ran a raw sql query equivalent to the above ORM like below with connection.cursor() as cursor: cursor.execute("SELECT app_tenantkey.key_id, app_tenantkey.name FROM app_tenantkey WHERE app_tenantkey.value=%s",[key]) row = cursor.fetchone() Surprisingly this query was way faster than the ORM which is what we were expecting as the table is very small and contains about 20 entries. I'm also attaching the max durations of both queries just FYI Raw Query ORM Query The ORM query is taking almost 100x when compared to time taken by the raw query in similar situation. I want to understand what's causing the ORM is taking so long while the raw is quick. -

How to add a list of booleans per user to a django model?
In addition to the basic user model I have a second custom model in my django app. This model is called a challenge. I want this challenge object to contain a list of booleans for each user where I can store which users have completed this challenge. This list must be able to do the following things: Whenever a new user is added, each existing challenge object needs to get a new boolean which is set to false. Whenever a user is deleted the corresponding booleans in each challenge must be removed also. Whenever a user completes a challenge the list inside the challenge object must be updated. How do I do this? I think I need to use some sort of ForeignKey of ManyToOne relationship, but I really have no idea how to go about this. I added a ManyToMany field and gave it the paramter User, but that only gave me a list of all Users where I could’t remove any of the users. -
