Re: Simple History - Field Change

It sounds like you haven't applied the table changes to the cloned table which it creates to track changes.

I'd advice using something like South to manage your schema changes, and this should work out of the box with django-simple-history. 

For now, you can delete the cloned table and re-sync, you will naturally lose the historical data but if you deleted the original then this probably won't matter.

It's also worth mentioning that the design approach of django-simple-history is completely wrong, and personally I wouldn't recommend using it. Feel free to start a separate thread if you'd like to discuss that further though as it's slightly off topic for this thread.

Let us know how you get on.

Hi all,

I am getting this error on a modelform

  smallint out of range

But the form is actually submitting just fine and being stored in the DB.  I used to have a positive small int, but have changed it  (dropped the offending table, resync'ed, restarted the server...)

I have history = HistoricalRecords() as one of the fields  (ie am tracking changes with django-simple-history), and I wonder if this is effecting my ability to make changes to the model.

My other thought is that it is a caching problem somewhere.

has anyone come across this problem and have any idea how to fix?

many thanks,

Aaron
