对于我的应用程序，我有一些项目，用户可以在其中发表评论（Newcomments 类）发布。现在它发布得很好，但页面刷新。我正在尝试使用 AJAX/JQUERY，这样它就会在没有页面刷新的情况下发布。我正在关注这个railscasts教程。
因此，现在，帖子已写入我的数据库，并且页面没有刷新。但是当我刷新时，帖子会显示出来。我为特定项目呈现评论的页面位于 projects/_comments.html.erb 上。
问题：我将如何调整它以便呈现新的评论？
newcomments_controller.rb
def create
@newcomment = @commentable.newcomments.new(params[:newcomment])
if @newcomment.save
respond_to do |format|
format.html { redirect_to comments_project_path(@commentable) }
format.js
end
else
render :new
end
end

<span class="comment">
<%= form_for [@commentable, @newcomment], remote: true do |f| %>
<%= f.text_area :content, rows: 3, :class => "span8" %>
<%= f.hidden_field :user_id, :value => current_user.id %>
<%= f.submit "Add Comment", :class => "btn btn-header" %>
