How can I store history of ManyToManyField using django-simple-history. I used HistoricalRecords with attribute m2m_filds but it is throwing error: unexpected keyword argument 'm2m_fields'
I'm macro1 on GitHub, and I guess de facto maintainer of django-simple-history.
From your question it seems that you're just asking about general ManyToManyField support compared with other fields. The short answer is that we do not currently support it.
ManyToManyFields actually create an in-between model that represents the relationship between the two models you're working with.
If you want tracking on that relationship I would suggest making a 'through' model representing the relationship and passing that into the ManyToManyField constructor. You could then register that through model to have its history tracked. If you get errors like "unexpected keyword argument 'm2m_fields'" with that set up please open an issue in our tracker.
As the author of django-simple-history says this isn't possible to detect change in only specific fields because
As you already know simple-history doesn't look at the values being saved at all. It blindly saves a new historical version on every save or delete signal.
He also says it may be possible Field Tracker do this job.
