在Rails3.1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(子对象):
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响应被抛出到HTML响应中,我无法确定原因我的其他索引视图都没有这个问题,它们的代码也非常接近。

最佳答案
这不是JSON,这是inspect
输出你得到这个结果是因为each
返回@children
并且你在这里使用<%=
:
<%= @children.each do |child| %>
你只要这个:
<% @children.each do |child| %>
