Rails: Getting rid of generic “X is invalid” validation errors

Question

I have a sign-up form that has nested associations/attributes whatever you want to call them.

My Hierarchy is this:

class User < ActiveRecord::Bas         


        

Answer 1

Salil's answer was almost right but he never made it 100%. Here is the correct way to do it:

def after_validation
    # Skip errors that won't be useful to the end user
    filtered_errors = self.errors.reject{ |err| %{ person }.include?(err.first) }

    # recollect the field names and retitlize them
    # this was I won't be getting 'user.person.first_name' and instead I'll get
    # 'First name'
    filtered_errors.collect{ |err|
      if err[0] =~ /(.+\.)?(.+)$/
        err[0] = $2.titleize
      end
      err
    }

    # reset the errors collection and repopulate it with the filtered errors.
    self.errors.clear
    filtered_errors.each { |err| self.errors.add(*err) }
  end
