我目前有一个应用程序,其中包含用户状态并支持对这些雕像的评论。一切正常,直到我决定在每个状态下方呈现一个评论表单。成功提交后,我的 create.js.erb 会将新创建的状态添加到用户的提要中。这是我的代码:
此代码呈现各个状态,位于 shared/feed_item
<li id="<%= feed_item.id %>" class="block">
<%= feed_item.content %>
<%= render 'shared/feed_comment_form', object: feed_item %> //works fine without this line
</li>
我的 create.js.erb 状态
<% if @status.errors.any? %>
$("#new_status").replaceWith("<%= escape_javascript(render('shared/status_form')) %>");
<% else %>
$("<%= escape_javascript(render('shared/feed_item', feed_item: @status)) %>").hide().prependTo('.feed').fadeIn(1000);
<% end %>
共享/feed_comment_form
<%= form_for([object, @comment], :remote => true) do |f| %>
<%= render 'shared/error_messages_short', object: @comment %>
<div class="field">
<%= f.text_area :content, placeholder: "Enter comment...", rows: 1 %>
</div>
<%= f.submit "Post", class: "status-btn", id: "status_submit_#{object.id}" %>
<% end %>
这是错误

我不明白为什么变量 'object' 为空,因为我在 shared/feed_item 中传递了它 'feed_item'
任何帮助,将不胜感激。
