thing
使用jQuery / Ajax,我创建的对象未显示在视图中。
我想在此处将标记为东西的div附加到div上。index.html.erb
<h1>Listing things</h1>
<%= link_to 'New Thing', new_thing_path, id: "new_thing_link", remote: true %><br>
<% @things.each do |thing| %>
<div class="things">
<%= thing.user_name %>
<%= thing.topic %>
<%= thing.truth %>
<%= link_to 'Show', thing %>
<%= link_to 'Edit', edit_thing_path(thing) %>
<%= link_to 'Destroy', thing, method: :delete, data: { confirm: 'Are you sure?' } %><br><br>
</div>
<% end %>
<br>
因此,在控制器中,我让js formate响应了此自定义模板。前2个步骤按预期工作,我从服务器输出中获得200 OK。
create.js.erb
$(".actions").remove(); // remove the form
$("#new_thing_link").show(); //show the new link again
$('.things').append('<%= j render @thing %>'); //insert the new task into the index template
_create.html.erb
<tr id="topics">
<td><%= thing.user_name %> |</td>
<td><%= thing.topic %> |</td>
<td><%= thing.truth %></td>
</tr>
Things_controller.rb
def create
@thing = Thing.new(thing_params)
respond_to do |format|
if @thing.save
format.html { redirect_to things_url, notice: 'your posting was added.' }
format.js
else
format.html { render :new }
format.json { render json: @thing.errors, status: :unprocessable_entity }
end
end
end
但是新的div仅在刷新页面时显示。当我查看源代码而不刷新页面并且控制台未显示任何错误时,它就在那里。
这是服务器的输出,所以我知道正在创建记录,

该视图只是没有更新,正如我所期望的。我究竟做错了什么?这是turbolinks问题吗?
看来您使用正确。尝试进行此小的更改,并指定您的局部位置(请注意,您通往局部的路径可能不正确,因为我不知道您是如何组织事物的):
$('.things').append("<%= j render :partial => 'things/create', :locals => {:thing => @thing} %>");
