Django content types - how to get model class of content type to create a instance?

To get the model class associated with a content type in Django's contenttypes framework and create an instance of that model, you can use the get_model() method from the apps module. Here's how you can do it:

  • Import the necessary modules:
from django.apps import apps from django.contrib.contenttypes.models import ContentType
  • Retrieve the content type for the desired model:
# Replace 'myapp' and 'mymodel' with your app and model names content_type = ContentType.objects.get(app_label='myapp', model='mymodel')
  • Get the model class associated with the content type:
model_class = apps.get_model(app_label=content_type.app_label, model_name=content_type.model)
  • Create an instance of the model:
instance = model_class()

Here's the complete code snippet:

from django.apps import apps from django.contrib.contenttypes.models import ContentType # Replace 'myapp' and 'mymodel' with your app and model names content_type = ContentType.objects.get(app_label='myapp', model='mymodel') model_class = apps.get_model(app_label=content_type.app_label, model_name=content_type.model) instance = model_class()

This code will allow you to dynamically get the model class associated with a content type and create an instance of that model.
