Hi,
I'm looking into the details of migrations a little, and I ran into this
issue.
I have two migrations: The first creates a model, the second adds another
model and a field to the first model. I'd expect squashmigrations to patch the
AddField into the first CreateModel, but it finds "No optimizations possible".
What am I missing?
Thanks,
Shai.
