Django makemigrations thrown an error if I add a custom model (Tenant) with app_label='auth'
This is the model that I have class Tenant(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) name = models.TextField(unique=True) class Meta: app_label = "auth" When I makemigrations in a new venv or run pytest. I always get an error saying django.db.migrations.exceptions.NodeNotFoundError: Migration nqm_core.0001_initial dependencies reference nonexistent parent node ('auth', '0013_tenant') I tried the following ways to resolve this issue Remove migrations files and re migrate Fake migrations with zero and then re migrate Create new database and migrate Update django and migrate Create new venv and migrate None of the above ways worked. The issue got resolved only after I removed the app_label from class Meta for that model. Also I tried removing dependency in the initial migration file but the DB won't migrate at all. Is this a bug or is there a certain way with which I have to run the migration Currently, I only use the following commands ./manage.py makemigrations ./manage.py migrate -

Other methods on class based views in Django
I currently have a class based view with get(), post() and delete() methods for the following URL: /property/<str:property_uuid> This works fine and is great. However, I now want URLs such as /property/<str:property_uuid>/publish and /property/<str:property_uuid>/publish to make my API easier to use. These will be GET methods. I was hoping to have corresponding publish() and unpublish() functions and put these within my class. However, I'm not sure how to do this or if this is even posible with class based views? Would I have to go back to function based views with all my functions defined in a "property.py" file for ease of reference and then include this in my urls.py file? -

Django Complicated Query
I am using django restframework with my Django app and I need to create quite specific query. Here is the models.py: class TaskHours(models.Model): name = models.CharField(max_length=100) hours = models.FloatField() task = models.CharField(max_length=100) date = models.DateField() views.py: class TaskHoursView(generics.ListAPIView): serializer_class = TaskHoursSerializer queryset = TaskHours.objects.all() def get_queryset(self): start_date = self.request.query_params.get('start_date') end_date = self.request.query_params.get('end_date') return TaskHours.filter(date__range=[start_date, end_date]) and serializer is default one with class Meta with all fields. This qurey is working fine but I need to alter it. In the data there are entries which have same name and same date, but different tasks. What I would need is get all the tasks and hours worked with the same name and date to one object like this: { "name": "John", "date": "2021-04-14", "task": "cleaning", "hours": "4.5", "task": "hoovering", "hours": "2.0" } Now I am receiving it like this: { "name": "John", "date": "2021-04-14", "task": "cleaning", "hours": "4.5", }, { "name": "John", "date": "2021-04-14", "task": "hoovering", "hours": "2.0" } Is there any way how to merge the two objects into one? -

Django render_to_string does not render javascript
I'm working on a Django project in which I used render_to_string to pre-render HTML templates from the backend, and then I send them to the frontend as a response to an ajax call. rendered_html.append( [render_to_string("webapp/popup.html", context=shop_context), location['Logo'], location['LONG'], location['LAT'], location['id']]) return JsonResponse({"rendered_html": rendered_html}) I am appending this rendered_html into the frontend with javascript. The HTML code and the Django context variable work fine but the javascript in the file does not work at all. If I see the elements section from the developer's console, I can see that javascript is included but it does not work, not even a small console.log works. Is there a workaround to this or am I doing something wrong? Any help will be appreciated. -

How to find tags and replace inner content with python regex

Updating to Django 3.2 broke almost all Django-Pages
I'm developing on a Page which runs Django (with DRF) in backend and ReactJS in frontend. I recently updated to Django v. 3.2. After this, whenever I wanted to open any Django specific pages, it gives me the following error. The only Page I can open is the admin-login page, but after entering my credentials i get the error messsage. The pages which are made with ReactJS aren't broken. https://dpaste.com/HDXFRD2RM Now reverting it back to v. 3.1, no issues occur, but since that version won't be supported for long, I really want to change to version 3.2. I figure, the error is relevant to something with the database connection. These are the DB settings in Settings.py DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'shifts-db', 'USER': 'user', 'PASSWORD': 'passworrd', 'HOST': 'localhost', 'PORT': '3306', } } If I need to elaborate more, please tell me so. -
