问Rails -当调用NEW时，在显示窗体之前创建一条记录？

EN

def new
  @note = Note.create # instead of Note.new
end

def new
  @note = Note.new
end

def new_js
  @note = Note.create
end

<%= form_for resource, 
             :remote => true, 
             :html => { 'id' => 'autosave' }, 
             :url => resources_path(:format => :json) do |f| %>
  ...
<% end %>

var $form = $('#autosave');

// bind to the first success event from the form
$form.one('ajax:success', function(data, status, xhr) {
  // data contains our json object (your note as json)
  // now we update the form
  $form.attr('action', '/notes/' + data.id);
  $form.attr('method', 'put');
  $form.attr('data-method', 'put');
});

class ExampleController
  ...

  def create
    #
    # respond with the json object if format = json,
    # see the form above I'm passing the format with :url parameter in form_for
    #
    respond_with(resource) do |format|
      format.json { render :json => resource }
    end
  end
end
