Full feedback is at https://gist.github.com/954bcdf833c8aef4d2f9

There are 41 more models in the project that are tested without any problems.

It would be very appreciated that you could shed light on this problem.

As I remember correctly, I had a similar feedback.

In my case, the database is not initialized correctly, and the schema_migration table schema_migration damaged.

So my recommendation: try running rake db:migrate:status and see that it displays a list of the migrations you created correctly. If not, try re-creating the database and try again.
