As an admin, I want to view the change history of a text to keep track of all the modifications made over time.

DoD

• The change history of texts accurately records all modifications including who made the changes and when.
• Admins can easily access and navigate through the change history from the admin UI.
• The system supports rollback functionalities to revert to a previous version of the text.

Tasks

Requirements Gathering

• Collaborate with the admin team to understand the specific needs for tracking text modifications. #3
• Detail out the types of modifications that should be recorded in the change history. #4

Backend Development

• Create an API endpoint to retrieve the change history of a text.
• Set up a database structure to store detailed change logs, including timestamps and the identity of the admin who made each change.

Frontend Development

• Develop a user interface that displays the change history in a readable and navigable format.
• Implement features that allow admins to filter and search through the change history.
• Create a viewing option to compare different versions of the text side by side.

Version Control

• Integrate a version control system to track changes and facilitate rollbacks to previous versions.
• Develop functionalities to allow admins to tag specific versions of the text, facilitating easier referencing in the future.

Testing

• Prepare unit tests to ensure the change history is recorded accurately and reliably.
• Perform integration tests to validate the smooth integration with the existing admin UI and database systems.

Думаю имеет смысл сохранять историю для Page, Book, Article и Diverse.

Модель Document имеет Мета класс со значением abstract = True

abstract = True - по сути создает только слепок обекта, на основе такой модели в базе данных не будет создана таблица https://docs.djangoproject.com/en/4.2/topics/db/models/#abstract-base-classes

Так же я бы посмотрел готовые решения, например: https://django-simple-history.readthedocs.io/en/latest/

Используя данную библиотеку можно было бы сохранять историю изменений не имплементируя всю логику самим. Например:

#models.py

from simple_history.models import HistoricalRecords


class Document(models.Model):
    # ...
    history = HistoricalRecords()

    def __str__(self):
        return self.title

    class Meta:
        abstract = True

class Page(models.Model):
    # ...
    history = HistoricalRecords()

Добавляя history = HistoricalRecords() в Document модель мы соответственно добавляем историю изменений ко всем моделям наследованных он Document
