Django m2m_changed post_clear get cleared objects
In Django docs about m2m_changed signal, it's said that pk_set argument to the signal handler is None for clear actions: pk_set ... For the pre_clear and post_clear actions, this is None. But on post_clear action, how can one know what relations are removed? (On pre_clear it can be achieved by simply querying the relation, since it's not cleared yet.) -
MakeMigration Error on Django - ImportError: cannot import name 'UserProfile'
I want to create a back-end server for an online video website with Django. There are user information and video information in the database.

Trying to create an advertisement-like system to distribute ads to my website and further monetize it using Django
I have created a Django App which takes Image and Video Advertisements to the database and then renders it to a template where we can view every Ads and perform CRUD operations. Every Unique User may create or delete his own Ads. He will not be able to perform any operation on Other User's Ads. However, I want these Ads get circulated over my website (at first randomly, later we can distribute along the weight and type-investment of the advertisements) and circulate as it may be any type of advertisements from any Advertisement Company. Also, How will I distribute it into my website so that in every frame or container right advertisements appear. Secondly, I also want to know how can I help monetize my website and also how can i monetize advertisements and the idea of earning through advertisements. I am using Python and Django Framework and studying different packages to learn it. Please give me some tips and working of how to achieve this. Thank you for your time . -

Django render django-tag from html
Does anyone know if you can have a django tag, like {{ val }} render another tag within it? Something like: {{ val }} where val="{% static 'path/to/file' %}" and have that render the static file? The reason why i am asking is because i am trying to write easy pages with markdown and have a django app template render them for me with {{ val | markdown | safe }} now everything was fine locally because i was using relative paths for image links, however in production these all broke because they were not using {% static %}. So my goal is to try to swap the markdown links with the proper django static tags but i realize that django does not render a nested tag (or at least i was not able to find a way for it to do it). I am open to suggestions if there is an alternative better way as well since i've been at this for a few days! Thanks for the help in advance. -

What are the best plugins for django-cms in 2020?

Automatic ID Field Returning 'None' in Django
Hi I'm a beginner in Django trying to create a program that will save a model with some input. (Eventually I'll be using a form for that input but the request.POST would contains things I want to send to multiple different places so I can't just use a ModelForm) This is the code for the model: class Bid(models.Model): bid_owner = models.ForeignKey(User, on_delete=models.CASCADE, related_name="owner") bid_value = models.DecimalField(max_digits=6, decimal_places=2) bid_no = models.IntegerField(default=0, null = True, blank=True) bid_open = models.BooleanField(default=True, null = True, blank=True) bid_winner = models.ForeignKey(User, blank=True, default="None", null=True, on_delete=models.CASCADE, related_name="winner") def __str__(self): return f"My ID is {self.id} and this is {self.bid_owner}'s listing" and this is the code I'm calling in views.py: def bar(request): foo = Bid(bid_owner = request.user, bid_value = 25) foo.save() But it keeps bringing up the error " Field 'id' expected a number but got None". From the documentation I've seen the contents of the id field should automatically generate during saving so I'm at a loss on how to solve this. In rendering an HttpResponse showing the contents of 'foo' everything seems to be working except for the id. -
Right way to create nested objects and custom create method

How Session App Public-Key-Based Auth Works? And How to Apply It on Django App?
I am looking to implement this method of authentication on Django application. How it's works? And how to implement it ? The commonly expected user experience of being able to recover an account using a username and password is not possible. Instead, users are prompted to write down their long-term private key (represented as a mnemonic seed, referred to within Session as a recovery phrase) upon account generation. A user can use this backup key to recover their account if their device is lost or destroyed, and the user’s contacts will be able to continue contacting that same user account, rather than having to re-initiate contact with a new key. https://getsession.org/faq -
How to set a proxy model for foreign key query set in Django?
I have two models Parent and Child: class Parent(models.Model): some_field = models.IntegerField() class Child(models.Model): objects = models.Manager() custom_objects = managers.CustomManager() parent = models.ForeignKey(Parent) And one proxy model for Child: class ProxyChild(Child): class Meta: proxy = True If i want to get children of parent using custom manager i can do this: children = parent.child_set(manager='custom_objects').all() How can i get children of parent using ProxyChild, i think about this but it's not working: children = parent.child_set(model=ProxyChild).all() I need to get the set exactly through parent.child_set because I need access to the parent fields through child without additional queries to the database. Using ProxyChild.objects.filter(parent=parent).select_related('parent') has two cons: It is heavier. If i want to use a proxy model for parent and then filter the children then Django set the original class of parent(not proxy), for example: class ProxyParent(Parent): class Meta: proxy = True parent = ProxyParent.objects.all().first() child = ProxyChild.objects.filter(parent=parent).select_related('parent').first() print(child.parent) child.parent will be instance of Parent class not ProxyParent -
Are there advantages to using IntegerChoices field in a Django model if it's not shown to users?
I'm using IntegerChoices in my Django (3.2) model. class AType(db.IntegerChoices): UNKNOWN = 0, 'Unknown' SOMETHING = 1, 'Something' ANOTHER_THING = 2, 'Another thing' A_THIRD_THING = 3, 'A third thing' class MyObject(models.Model): a_type = db.IntegerField(choices=AType.choices) (I've changed the choices to be more generic.) Every time I add a value to AType, it produces a DB migration, which I faithfully apply. a_type is strictly behind the scenes. Users never see it, so it's only in the admin UI, but I don't need it to be editable. So forms aren't really used. Is there any impact on the DB (e.g., constraints) of these migrations? Is there any other utility to having an IntegerChoices field, given that it's not displayed to a (non-staff) user, and not in a form? If there's no utility, I'm thinking of just changing MyObject.a_type to an IntegerField, and continuing to use AType everywhere, but not having all the migrations. -
