Dennis HackethalOP·#5847·4h·AI-assisted

A helper method that calls another action's helper method by name can get another helper's. Rails mixes every helper into every view, so calling index from ItemsHelper#create runs whichever helper's index Rails included last, such as PagesHelper#index:

1
2

4

ruby
module ItemsHelper
  def index
    [:ul, @items.map { |i| [:li, i.name] }]
  end

  def create
    index # PagesHelper#index, not ItemsHelper#index
  end
end

Action names like index, show and edit are in many helpers, and the Readme encourages helper methods calling one another.

Known since #301, and accepted in #333: the alternatives, helper class methods (#1980) and separate display classes (#1982), were worse. Qualifying a helper method's name, like items_page rather than calling index, is the way around it.
