The resource_integration_test fails sometimes. Please have a look in the build stats:
This is interesting. Specs are expecting 12.32, Page renders 12. Seems like a weird rounding/float-converting-error. I'll have a look at that. The test is right though, 12 is not 12.32...
It's a mysql issue with decimal columns. Explicitly passing :precision and :scale in schema.rb fixed the problem on travis ci.
