crash on startup with port from 2 to 3a
You need the 3.0a branches of wtf-peewee and flask-peewee, if your project depends on those libraries. Since I haven't merged 3.0a into master yet, you'll need to use the branches. When 3.0a is merged into peewee master, I'll merge the other libraries as well.
Thought I would try the 3.0a version

I was running peewee==2.10.1
did a pip uninstall of peewee and then installed peewee 3.0a

And then just ran my code ...

Got some errors right off ... ideas?  Is there a list of changes we should make to port up?
For example
"importError: cannot import name PrimaryKeyField"

Thanks!

Some more details
