Namespace for form field ids

[silentvick]

I guess there is no :namespace option for form_for helper like in Rails. So,
how do I use several forms for the same model in the same page? Besides of manual settings :id attribute.

Padrino has no such option. Instead of manually setting :id each time you can do something like this:

  class MyBuilder < Padrino::Helpers::FormBuilder::StandardFormBuilder
    def field_id(field=nil, value=nil)
      result = []
      result << (@options[:namespace] || object_model_name) if root_form?
      result << field_id_fragment if nested_form?
      result << "_#{field}" unless field.blank?
      result << "_#{value}" unless value.blank?
      result.flatten.join
    end
  end

 class App < Padrino::Application
    set :default_builder, MyBuilder

    helpers do
      def form_tag(url, options={}, &block)
        options.delete(:namespace)
        super
      end
    end

    # ...
end  

Which is probably a few test cases and a small refactor away from a patch...
