Rails 3.2.14, Ruby 1.9.3, devise_invitable 1.1.8
I am trying to get invitations containing custom fields to validate their contents properly. I have tried the invite_keys hash route, as documented here: https://github.com/scambra/devise_invitable#model-configuration and unless I am doing something wrong with my Regexps, what happens is the fields are validated, but the error messages are incorrect.
I also tried adding regular validations on the model, but they aren't being called at all (only the built-in e-mail error is handled). When I tried adding validate_on_invite to my model, I got an error: uninitialized constant Devise::Models::ValidateOnInvite when I started the application.
Is there an example somewhere showing how to configure the model to validate custom fields on invitations?
1. Just to clarify what I mean by error messages are incorrect: If all the fields are left blank, there is an error on each field saying "[field name] cannot be blank". That's as expected. If any of the fields are properly filled in, then that field is listed in the errors as "[field name] is invalid", while the missing fields still say "[field name] cannot be blank". Only if all fields are properly filled in does the form submit, naturally. I would expect the fields that match their regexp to not have errors attached at all.
