field_for_type Argument Error Doesn’t Read as Expected

[jacobdaddario]

I’m opening this issue in relation to some of the trouble I ran into with #98. After more investigation I believe the error that can be raised in field_for_type isn’t functioning quite as expected. Particularly the names being inserted into the error string don’t make sense. I believe it’s catching an error not expected by the original implementation.

I’ll continue to investigate and document my findings here when I get #98 finished.

This should be much more clear (and we can continue improving it) as needed.
