我如何使用 savon 嵌套属性！哈希? [英] How do I use savon nested attributes! hash?

问题描述

我正在考虑将 Ruby savon 用于 SOAP.纯粹出于自虐的原因，我必须处理具有属性的 SOAP 元素.

I'm looking at using Ruby savon for SOAP. For purely masochistic reasons I have to deal with SOAP elements having attributes.

所以，没问题，savon docs 站点上有一个突出显示此功能的示例:

So, no problem, there is an example on the savon docs site which highlights this ability:

{ :person => "Eve", :attributes! => { :person => { :id => 666 } } }.to_soap_xml
"<person id=\"666\">Eve</person>"

我的问题是如何在子元素上设置属性，例如，假设我向person添加一个地址子元素:

My problem is how do I set attributes on child elements, for example, say I add an address child element to person:

{ :person => {:address => ""}, :attributes! => { :person => { :id => 666 } } }.to_soap_xml

现在我想给地址元素添加一个 id 属性:

Now I want to add an id attribute to the address element:

如果我在属性哈希中嵌套地址是不行的:

It's no go if I nest address in the attributes hash:

{ :person => {:address => ""}, :attributes! => { :person => { :id => 666, :address => {:id => 44 }} }}.to_soap_xml

所以我的问题是，我怎样才能得到这个?

So my question is, how can I get this?

<person id=666><address id=44></address></person>

推荐答案

你已经很接近了 - 只需要将 :attributes! 键放在包含该值的同一个哈希中.

You were close - just needed to put the :attributes! key in the same hash that contains the value.

{
  :person => {
    :address => "", 
    :attributes! => { :address => { :id => 44 } }
  }, 
  :attributes! => { :person => { :id => 666 } } 
}.to_soap_xml

# => "<person id=\"666\"><address id=\"44\"></address></person>"
