Rails 3.0.x: undefined method *heading*, issue with ActionDispatch::Reloader

[jensb]

Using Rails 3.0.20 and Ruby 1.9.3, I get this error when trying to access the apipie index:

NoMethodError in Apipie/apipies#index

Showing .../ruby1.9/gems/1.9.1/gems/apipie-rails-0.1.3/app/views/apipie/apipies/_method_detail.erb where line #34 raised:

undefined method `heading' for #<#Class:0x007fabe6e27770:0x007fabe6ddc658>
Extracted source (around line #34):

31: <% end %>
32: 
33: <% unless method[:params].blank? %>
34:   <%= heading('Params', h_level) %>
35:   <table class='table'>
36:     <thead>
37:       <tr>

If this is Rails-3.0 specific: I know that Rails 3.0 is deprecated, but if a fix is trivial (it's in a template, after all), can you provide a patch?
Thank you!

Hi,

I will be happy to review the patch

[jensb]

I don't have a patch - sorry :) It just looks like your "heading(...)" helper isn't included and thus throws an unknown_method on each page. Since this is the only helper and it is trivial, I just included the method in my main ApplicationHelper, and now it seems to work.

Still, I'd like to know why the apipie_helper.rb isn't being loaded.

Also, for Rails 3.0 it is necessary to duplicate / monkey-patch Apipie::Application, eg. append to config/initializers/apipie.rb:

module Apipie
class Application
  def rails_mark_classes_for_reload
    unless Rails.application.config.cache_classes
      #ActionDispatch::Reloader.cleanup!
      init_env
      reload_examples
      #ActionDispatch::Reloader.prepare!
    end
  end
end
end

🐛 This is an issue on: rails (4.0.12) and ruby 2.1.5

@iNecas this seems to have resolved the issue for my project.
