cluster-1279

Custom model initialization during Django migrations fails because managers and model relationships aren’t configured for the migration context. Using a data-migration and enabling the manager for migrations ensures the new instances and related media records are created correctly.

INSTANCE_OFProblem

hash could not be identified — When I insert the username and password in my fastapi login form. Tension: The passwords in the database are already hashed (I'm using the same database from the Django project). Outcome: I've also tried `password = form.get("password")`, and the error still pops up.

INSTANCE_OFProblem

I'm trying to create a default user, specifically a superuser, in an early data migration. Tension: I've seen when adding initial data to a Django project, the best practice is to do it through a Data Migration. Outcome: I had already tried different options for creating said superuser.

INSTANCE_OFProblem

the keys that can show up in the dictionary are limited to a certain set — for the <code>something_dict</code> field I thought it could be a good idea to use <code>serializers.DictField</code>. Tension: I can't.

INSTANCE_OFProblem

exclude certain fields that are not necessary in this case the user's password — to get the information of a user I use a serializer with nested serializers.

INSTANCE_OFProblem

Tension: that I don't notice.

INSTANCE_OFProblem

There were three problems in my code: — I have a django project which I want it to have phone number as its username field.

INSTANCE_OFProblem

What is the actual use of Mixins class? I don't really get it. — All the mixins classes like CreateModelmixin, Listmixin, etc features are already available in class-based view like ListCreateApiView. Tension: the mixins classes like CreateModelmixin, Listmixin, etc features are already available in class-based view.

INSTANCE_OFProblem

I have a model that has an ImageField. — I want users to be able to upload multiple images for an object of the model. Tension: not only a single image. Outcome: You cannot store several images in one ImageField.

INSTANCE_OFProblem

It works, sort of, but the result adds an extra quote to my string. — I need to annotate a value that is saved in a json field in the same model. Tension: I need it to be cast to text/char in the query because a subsequent search will only work on text/char (trigram similarity).
