[Answer]-Django database and information history

✅

Firstly, Because You’ll want to access your user’s history directly from a User instance, use django’s ForeignKey field.

When doing so, accessing a users history will look something like this:

my_user.information_set.all()

You can change the name the user’s history from ‘information_set’ to, for example, ‘history’, by specifying related_name argument in the ForeignKey constructor, like so:

Class Information(models.Model):
     ...
     user=models.ForeignKey(related_name='history')

And now to access a user’s history, you can write:

my_user.history.all()

Also, Please notice that in your current design, the info won’t be stored in the database.
I assume that most of the history data you want to store will have the same structure. Consider using a field for each piece of info you want to keep in your history. For example, for keeping the date and time of the action, use DateTimeField
