Rails: Using form tags inside lib

Question

So I have this code inside my lib/ folder:

class GlobalConfig::SetHelper
  def self.yes_no_input(configuration)
    value = configuration.value
    name = configuration.name
    "#{radio_button_tag name, true, (value == true), {:id => "#{name}_yes"}} #{label_tag "#{name}_yes", 'yes'}
     #{radio_button_tag name, false, (value.blank? or value == false), {:id => "#{name}_no"}} #{label_tag "#{name}_no", 'no'}"
  end
end

But it returned: undefined method `radio_button_tag' for GlobalConfig::SetHelper:Class when I run the code.

How do I fix this. Anyone?

Thanks

Answer 1

1. Why do you put this into lib? app/helpers is the standard place to put helper methods like this.

2. Having helper methods as class methods of the helper class is not the way to go. You should rather make it an instance method. Then put this code into your controller:

   helper GlobalConfig::SetHelper

   and you'll have access to its methods inside your views. And standard helper methods like radio_button_tag will also work at once.

Answer 2

You need include in your helper the Helper with this method :

class GlobalConfig::SetHelper
  include ActionView::Helpers::FormTagHelper
end
