Answer 1

The object assigned form_foris an instance ActionView::Helpers::FormBuilder. So all you have to do is add the instance methods there.

class ActionView::Helpers::FormBuilder
  def custom_field(...)
    ...
  end
end

Answer 2

: nice_editor? , ActionView:: Helpers:: FormBuilder . /. FormBuilder.

, , items_helper.rb:

module ItemsHelper
    # this is one way to define new instance methods
    ActionView::Helpers::FormBuilder.class_eval do
        def nice_editor(conf,*opts)
            ...
        end
    end
end

. , , self.included() FormBuilder.

Answer 3

class ActionView::Helpers::FormBuilder
    def nice_editor(conf)
