Rails - Oct 2011 - Form helper in a content_tag

Hi,

I want to add a form helper in a content_tag like this:

  def custom_field(form, attribute_name, form_helper, message = "")
    error = form.object.errors.get(attribute_name).present?
    klasses = ["clearfix"]
    klasses << "error" if error

    content_tag :div, :class => klasses.join(", ") do
      form.label :attribute_name
      content_tag(:div, :class => :input) do
        form.send(form_helper, attribute_name, :class => (error ?
"error" : nil))
        content_tag :span, :class => "help-inline" do
          form.object.errors.get(attribute_name)
        end
      end
    end
  end

This works but the form helper aren''t rendered. What do I have to do to
render the form helpers??

Gregory

Here is the solution:

  def custom_field(form, attribute_name, form_helper, message = "")
    error = form.object.errors.get(attribute_name).present?
    klasses = ["clearfix"]
    klasses << "error" if error

    content_tag :div, :class => klasses.join(", ") do
      concat(form.label(attribute_name) +
        content_tag(:div, :class => :input) do
          concat(form.send(form_helper, attribute_name, :class => (error 
? "error" : nil)) +
            content_tag(:span, :class => "help-inline") do
              concat(form.object.errors.get(attribute_name).join(".
"))
            end)
        end)
    end
  end
