This is super cool.

Just like I can post a form to my controller and have it deserialize  
into a ruby object, I can also post xml to my controller and it  
deserialize into my ruby object. And all I had to do was set the  
appropriate content-type.

Wow.

Yes. This is cool, and it is funny because I just created an account  
with ruby-forum for the sole purpose of finding out how this is done  
under the hood, and your post is the latest in the list as of this…

I imagine you are doing some REST development like I am.

Can someone please explain to me or point me in the right direction why

$ curl -X POST -H ‘Content-Type: application/xml’ -d   
‘  
true  
Bar  
Foo  
’ [http://localhost:3000/projects](http://localhost:3000/projects)

(notice the content-type explicitly set) serializes the XML into a Hash  
while a standard post does not? The magic is too mind-boggling for me to  
grok…

Hi,

Yeah, I’m working on a REST API.

I’m still in awe about how it was just handled automatically… I  
figured that AT LEAST, somewhere down the line, I’d have to call  
MyObject.new.from\_xml… but no…

This is the example I give with curl:

curl -H “Content-Type: text/xml” -d “big traffic jam\</  
name\>\<category\_id\>1\</category\_id\>this is the message subject\</  
subject\>this is the message body”

What do you mean by ‘standard post’?
