Rails:渲染 XML 添加 <hash>标签 [英] Rails: rendering XML adds <hash> tag

问题描述

我有一个 Rails 控制器，它将以 XML 格式输出哈希 - 例如:

class MyController <应用控制器# 获取/example.xml定义索引@output = {"a" =>"b"}response_to do |格式|format.xml {render :xml =>@输出}结尾结尾结尾

然而，Rails 添加了一个 <hash>标签，我不想要，即:

<a>乙</a></hash>

我怎样才能只输出这个?

乙</a>

解决方案

我认为，如果您要将对象转换为 XML，您需要一个包装所有内容的标签，但您可以为包装器自定义标签名称:

>

def 索引@output = {"a" =>"b"}response_to do |格式|format.xml {render :xml =>@output.to_xml(:root => '输出')}结尾结尾

这将导致:

<a>乙</a>

I've got a Rails controller which is going to output a hash in XML format - for example:

class MyController < ApplicationController
  # GET /example.xml
  def index        
    @output = {"a" => "b"}

    respond_to do |format|
      format.xml  {render :xml => @output}
    end
  end
end

However, Rails adds a <hash> tag, which I don't want, i.e.:

<hash>
  <a>
    b
  </a>
</hash>

How can I just output this instead?

<a>
  b
</a>

解决方案

I think if you're converting an object to XML, you need a tag which wraps everything, but you can customise the tag name for the wrapper:

def index        
  @output = {"a" => "b"}

  respond_to do |format|
    format.xml  {render :xml => @output.to_xml(:root => 'output')}
  end
end

Which will result in:

<output>
  <a>
    b
  </a>
</output>
