Django abstract model with indices, constraints and permissions: attributes are not inherited by sub classes
I am using Django 3.2 I have the following models: app1 class IsPinnable(models.Model): is_pinned = models.BooleanField(default=False) pin_after_expiry_day_count = models.DurationField(default=0) class Meta: abstract = True indexes = [ models.Index(fields=['is_pinned' ]), ] class IsModeratable(models.Model): approved = models.BooleanField(default=False) target_count_trigger = models.PositiveSmallIntegerField() positive_pass_count = models.PositiveSmallIntegerField(default=0) negative_pass_count = models.PositiveSmallIntegerField(default=0) # Other fields and methods ... def save(self, *args, **kwargs): # TODO: Sanity check on pass_count and trigger sizes # ... super().save(*args, **kwargs) class Meta: abstract = True permissions = ( ("moderate_item", "can moderate item"), ("reset_moderation", "can (re)moderate a moderated item"), ) indexes = [ models.Index(fields=['approved' ]), ] class MyComponent(IsPinnable, IsModeratable): # some fields and methods ... class Meta(IsPinnable.Meta, IsModeratable.Meta): abstract = True # other stuff ... app2 from app1.models import MyComponent class Foo(MyComponent): # some fields and methods ... class Meta(MyComponent.Meta): abstract = False Now, I know that abstract model classes are not created in the database - so I was initially expecting Django to throw an exception when I attempted to makemigrations - to my surprise, I was able to makemigrations && migrate.

Django changing template_name in get_context_data dynamically
how do I override the template_name of a TemplateView based on the context in get_context_data? In other words, I would like to find a way to change the template rendered according to my context. The following is modified from my current code and it does not work: class FooPage(TemplateView): template_name = "folder/template1.html" def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['myvariable'] = MyModel.objects.get(pk=kwargs['some_criterion']).variable if "text" in context['myvariable']: template_name = "folder/template2.html" # This line does get executed return context I can confirm that the line changing template_name is executed and it is indeed set to "folder/template2.html" at that point, but the actual page that gets rendered still looks like the original (template1.html) instead. Any helpful insight would be deeply appreciated. Thank you very much! -

What is the best practice for retrieving data from backend and using them in frontend form using REST API? [closed]
I am developing a REST API for an application in Django. It's frontend is being created in AngularJS. In create forms, there are fields that are related fields. For example, if a Car model is related to Manufacturer model, I want to send the list of manufacturers from the backend while creating Car. But, the issue is there might be multiple relationships in Car model like MadeInCountry, Distributers, etc. Also, based on logged in users and other criteria, I want to send filtered objects to be displayed in the form. How do I accomplish this using REST APIs? I have come to two conclusions for achieving this: Send data to be populated in form using GET method of the Create API and ask frontend to call that API. Ask frontend to call list API of every related field and send filtered data to be used in the form. Which method should I use? Or, are there any more efficient and best practice for this? -

Django: Receive data from form once
I don't know exactly how to name this question, but this is my problem. I have a calendar which behavior depends on get parameters. I have 2 basics GET params: month and year so it renders calendar for specific year and month. My problem: I need option to change month to next / previous. I can easily do that with JS using ajax, but now I want it to work for non-JS users as well. I tried: next_month / prev_moth GET param so I render calendar depending on that params, but here's the problem with this approach: if user refresh page, wrong calendar is rendered because refreshing is just repeating request so params will be saved so if user refresh page 10 times he will get calendar from 10 months before (if there is prev_month get param). I can't remove get params because QueryDict is immutable. -
