Custom User Migration Error

[mdd...@gmail.com]

Hi everyone,

I've recently started adding user authentication to my app using Google's OAuth2. I found a sample app online (http://blog.jez.io/2014/10/20/using-google-apps-for-cmu-authentication/), tweaked it slightly for my own needs, and got it working. However, once I tried changing the database to MySQL (the sample was just using the default SQLite3), I receive this ValueError: Lookup failed for model referenced by field admin.LogEntry.user: myApp.CustomUser.

This is the only thing that I've changed and I've scoured the internet with no luck. Any help would be greatly appreciated. 

Thank you!

Here is the full stacktrace for reference:
