QUESTION
I am using a viewset
where there is a partial_update
method that updates the values of a model instance. What I would like to do is to save the old model instance in a variable and then save the model instance with the new values so that I can compare some values after the new values are saved in database.
ANSWER
Answered 2020-Nov-24 at 09:28If you look to check for changes in specific fields on a model have a look at this library django model utils. It has a nice FieldTracker
that you can use to track the changes in an instance and add some logic when that happens.
Otherwise, if you just want to have a history of changes just use an audit library, there are a lot of packages to use from django packages depending on your needs.
