undefined methodcolumns_hash' for #Her::Collection:0x007fc86d2704d8` Attempting to use her-based models with Thoughbot's Administrate.

I'm looking at monkey patching this in, but it looks like columns_hash returns information about the database table in ActiveRecord and that its something that Administrate is using to figure out what to do.
