为用户显示微博评论

Question

在Micropost's comments on users page (Ruby on Rails)的基础上，我能够为每个微博添加新的评论。但是，我在同一页面上显示每个帖子的评论时有问题。下面的代码没有抛出任何错误，所以我认为每个微博的注释没有正确分配，所以不能显示。

用户>微博>评论

users_controller.rb

  def show
    @user = Account.find(params[:id])
    @microposts = @user.microposts
    @micropost = Micropost.new
    @comments = @micropost.comments
    @comment = Comment.new
  end

microposts/_micropost.html.erb

<li>
  <span class="content"><%= micropost.content %></span>
  <span class="timestamp">
    Posted <%= time_ago_in_words(micropost.created_at) %> ago.
  </span>

  <span class="comments">
    <% if micropost.comments.any? %>
    <ul class="comments">
      <%= render @comments%>
    </ul>
    <% end %>

    <%= render "shared/form_comment", micropost: micropost %>
  </span>

</li>

comments/_comment.html.erb

<li>
  <span class="content"><%= comment.content %></span>
  <span class="timestamp">
    Posted <%= time_ago_in_words(comment.created_at) %> ago.
  </span>
</li>

Answer 1

将<%= render @comments%>更改为<%= render micropost.comments %>，以循环特定帖子的注释，而不是使用泛型注释循环。

Answer 2

<li>
  <span class="content"><%= micropost.content %></span>
  <span class="timestamp">
    Posted <%= time_ago_in_words(micropost.created_at) %> ago.
  </span>

  <span class="comments">
    <ul class="comments">
      <%= render micropost.comments %> # you can leave out the #any?
    </ul>
   </span>

</li>
