I'm seeing the following error in a web2py 2.14.6 app @ pythonanywhere
OperationalError: (1553, "Cannot drop index 'f_User__idx': needed in a
foreign key constraint")
This is an app that is using MySQL. I have not changed any models, and all
migrations are disabled, either of which not being true is what I might
think could trigger this kind of error. I do notice that everything in the
compiled folder seems to have the same very recent timestamp, as if they
were all touched recently.
I realize this is thin on details, but any ideas as to how I can a) track
down the problem and more importantly b) solve it?
Here's the full traceback:
