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）贴子。现在它发布很好，但页面刷新。我正在尝试使用AJAX/JQUERY，以便它不会刷新页面。我正在关注这个railscasts教程。Rails - AJAX/JQuery不起作用
所以现在，这些帖子是对我的数据库和页面不刷新。但是，当我刷新时，帖子显示。我为特定项目呈现我的评论的页面位于projects/_comments.html.erb上。
问题：我该如何调整它以使它对新评论进行渲染？
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
视图/ newcomments/_form.html.erb
<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" %>
<% end %>
</span>
视图/ newcomments/create.js.erb
$('#newcomment').append('<%= j render(@newcomments) %>');
projects_controller.rb
def comments
@commentable = @project
@newcomments = @commentable.newcomments.newest.page(params[:comments_page]).per_page(10)
@newcomment = Newcomment.new
respond_to do |format|
format.html # show.html.erb
format.json { render json: @project.comments }
end
end

<%= render 'comments' %>
