How to implement Django model audit trail? How do you access logged in user in models save() method?

I want to keep track of the user who creates and then updates all of a given model's records. I have the "user" information in the logged in user's UserProfile (all users must be logged in to update these records).

I find django-simple-history very easy to use. Importantly, it has a customisation available for tracking reason of change which can be strategically used to get input from users for knowing the reason.

It sounds like you're looking for django-reversion, which allows you to keep track of all changes to a given model, including some meta data about the change (e.g. who made it).

The quickest way to set the user field automatically for all changes made in the admin, would be by overriding the save_model method in your admin class (from the Django docs):

class ArticleAdmin(admin.ModelAdmin):
    def save_model(self, request, obj, form, change):
        obj.user = request.user
        obj.save()

Otherwise, you can use something like django-revision mentioned by Dominic Rodger.

Django models do not (on purpose) have access to the request object. You must pass it to the model in a view.
