## [plaintext] Using Ajax.InPlaceCollectionEditor and in_place_collection_editor_field. This worked for me: ## application_helper.rb [ruby] def in_place_collection_editor_field(object,method,container, tag_options={}) tag = ::ActionView::Helpers::InstanceTag.new(object, method, self) tag_options = { :tag => "span", :id => "#{object}_#{method}_#{tag.object.id}_in_place_editor", :class => "in_place_editor_field" }.merge!(tag_options) url = url_for( :action => "set_#{object}_#{method}", :id => tag.object.id ) collection = container.inject([]) do |options, element| options << "[ '#{escape_javascript(element.last.to_s)}', '#{escape_javascript(element.first.to_s)}']" end function = "new Ajax.InPlaceCollectionEditor(" function << "'#{object}_#{method}_#{tag.object.id}_in_place_editor'," function << "'#{url}'," function << "{collection: [#{collection.join(',')}], id: '#{object}_#{method}'});" tag.to_content_tag(tag_options.delete(:tag), tag_options) + javascript_tag(function) end ## products_controller.rb [ruby] in_place_edit_for :product, :alt_event_name ## edit.rhtml [rhtml] <%= in_place_collection_editor_field :product, :alt_event_name, event_options -%>
