Rails 3教程第11章跟随/取消跟随按钮不显示HTML

Question

这是我的show.html.erb文件。

<% provide(:title, @user.name) %>
<div class="row">
    <aside class="span4">
        <section>
            <h1>
                <%= gravatar_for @user %>
                <%= @user.name %>
            </h1>
        </section>
        <section>
            <%= render 'shared/stats' %>
        </section>
    </aside>
    <div class="span8">
        <%= render 'follow_form' if signed_in? %>
    <% if @user.microposts.any? %>
      <h3>Microposts (<%= @user.microposts.count %>)</h3>
      <ol class="microposts">
        <%= render @microposts %>
      </ol>
      <%= will_paginate @microposts %>
    <% end %>
  </div>
</div>

_follow.html.erb部分文件：

<%= form_for(current_user.relationships.build(followed_id: @user.id),
             remote: true) do |f| %>
  <div><%= f.hidden_field :followed_id %></div>
  <%= f.submit "Follow", class: "btn btn-large btn-primary" %>
<% end %>

_unfollow.html.erb部分文件：

<%= form_for(current_user.relationships.find_by_followed_id(@user),
             html: { method: :delete },
             remote: true) do |f| %>
  <%= f.submit "Unfollow", class: "btn btn-large" %>
<% end %>

我的_follow_form.html.erb partial：

<% unless current_user?(@user) %>
  <div id="follow_form">
  <% if current_user.following?(@user) %>
    <%= render 'unfollow' %>
  <% else %>
    <%= render 'follow' %>
  <% end %>
  </div>
<% end %>

编辑:我还想说我正在使用Bootstrap。当我检查用户页面时，两个类span4和span8都出现了，但是"follow_form“所在的位置是一片空白。

编辑:这个问题几年前就回答过了:)

我遇到了同样的问题，您可以通过执行以下更改来纠正此问题：

步骤1)在app/views/users/show.html.erb中，将代码更改为：

<div class = "span8">
    <%= render 'follow_form' if signed_in? %>      
        <% if @user.microposts.any? %>

要这样做：

<div class = "span8">
    <%= render 'shared/follow_form' if signed_in? %>      
        <% if @user.microposts.any? %>

步骤2)在部分app/views/shared/_follow_form.html.erb中

将代码更改为：

<% unless current_user?(@user) %>
  <div id="follow_form">
  <%if current_user.following?(@user) %>
    <%= render 'unfollow' %>
  <% else %>
    <%= render 'follow' %>
  <% end %>
  </div>
<% end %>

要这样做：

<% unless current_user?(@user) %>
  <div id="follow_form">
  <%if current_user.following?(@user) %>
    <%= render 'shared/unfollow' %>
  <% else %>
    <%= render 'shared/follow' %>
  <% end %>
  </div>
<% end %>
