Upgrading to rails 4.2, model problems now give LoadError: it is impossible to auto-fix persistent problems :: blahblah

Question

I wrote a generator that is of concern to the user for inclusion in their model. It works correctly on Rails 4.1.8, but on Rails 4.2.0 I get this message:

LoadError: Unable to autoload constant Concerns::NameSearch.

NameSearchis the anxiety module that the generator creates app/models/concerns/name_search.rb:

module NameSearch
  extend ActiveSupport::Concern

  included do
    ...
  end

  module ClassMethods
    ...
  end

private
  ...
end

But in the model I’m simple include NameSearch. I get an error when I run the rake (jump) task after turning on the problem. The application really works correctly, it's just a rake task that throws an error. And the rake task also seems to have done the job, but in the end this error. Again, this worked fine in 4.1.8, but not in 4.2.0. Any idea what has changed?

Answer 1

Ruby ( Concerns::):

///name_search.rb

module Concerns::NameSearch
  extend ActiveSupport::Concern

  included do
    ...
  end

  module ClassMethods
    ...
  end

private
  ...
end
