在我的Rails应用程序中,JSON格式的结果出现在HTML视图响应中

Question

在Rails 3.1应用程序中,我有一个控制器使用以下代码在索引视图中返回一组对象(子):

    def index
        @children = Child.all

        @base_class = "children-index"
        @title = "Your Children"

        respond_to do |format|
            format.html # children/index.html.erb
            format.json { render :json => @children }
        end
    end

index.html.erb视图的编写方式如下:

<h1><%= title %></h1>
<ul>
  <%= @children.each do |child| %>
    <li><%= link_to child.fullname, child_path(child) %></li>
  <% end %>
</ul>

出于某种原因,JSON响应被抛入HTML响应中,我无法确定原因.我的其他索引视图都没有出现此问题,并且它们的代码非常接近.

Answer 1

这不是JSON,那是inspect输出.你得到的是因为each回归@children并且你在<%=这里使用:

<%= @children.each do |child| %>

你想要这个:

<% @children.each do |child| %>
