How to merge two records of the same model into one record?

Question

Django

To link a model to another model, you need the get method. There is a multiple object error, how can these cartoons be combined into one record?

Answer 1

Poor wording of the question, because:
1. joins on the wording can help (at the request level from the database)
2. Inheritance of two classes, in theory too.
3. Normal relation (most likely this is what it is).
