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??

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
