我创建了一个博客。每当我添加帖子时,帖子索引页面 ( ) 的底部都会显示数据库中的记录列表home.html.erb,如下所示:
[#<Post id: 1, title: "hahaha", content: "Because the gravatar_for method is undefined, the u...", public: true, created_at: "2013-03-18 04:00:17", updated_at: "2013-03-18 04:01:09">]

我尝试过删除<%= will_paginate @posts %>,但没有成功。
这是我的home.html.erb:
<%= @posts.each do |post| %>
<article class="posts">
<h2><%= link_to post.title, post_path(post) %></h1>
<h3><%= post.public %></h3>
<p><%= truncate markdown(post.content), length: 400, omission: " ......" %></p>
<span class="continue"><%= link_to "... Continue Reading ...", post_path(post) %></span>
</article>
<% end %>
<%= will_paginate @posts %>

这是我的 Gemfile,以防万一您需要它:
source 'https://rubygems.org'
gem 'rails', '3.2.12'
gem 'pg'
gem 'redcarpet'
gem 'will_paginate'
gem 'redcarpet'
gem 'coderay'
group :development, :test do

这是一个奇怪的情况。所以我想知道发生了什么?
谢谢你!
更改您的模板文件 -
<%= @posts.each do |post| %>
<article class="posts">
<h2><%= link_to post.title, post_path(post) %></h1>
<h3><%= post.public %></h3>
<p><%= truncate markdown(post.content), length: 400, omission: " ......" %></p>
<span class="continue"><%= link_to "... Continue Reading ...", post_path(post) %></span>
</article>
<% end %>
<%= will_paginate @posts %>

它出现是因为您正在使用 <%= @posts.each do |post| %> 而不是 <% @posts.each do |post| %>. <%= %> 将输出返回值,但 <% %> 不会
