Undefined method 'on' for ActionModel

Question

I\'m getting the following error:

NoMethodError in Users#new

Showing .../app/views/users/form/_new.haml where line #7 raised:

undefined method `on\' for #&         


        

Answer 1

If you're using Rails 3, then the problem is that there's no "on" method for the Errors class anymore. I think you're supposed to use "get" now. So:

error = case errors = model.errors.get(field)

Or...

error = case errors = model.errors[field]

Answer 2

I checked my user and u.errors is an ActiveRecord::Errors, while I see you have an ActiveModel::Error, I would work on that.

Then I don't understand case errors = statement in your helper, I'm curious to know how you implemented that part...
