In Rails, we can respond_to do |format| format.html format.json { render :json => @data } end so it knows to automatically show the @data in json format, but when it is xml, it needs to be format.xml { render :xml => @data.to_xml } why does it need to explicitly convert @data into XML? Can't it be just like json's case? to...

I googled a bit with no luck. I'm wondering if a tool exists that allows a user to paste in a chunk of valid JSON, click on any of its elements, and get returned the id (path) to that element.

I have a frustrating problem. I have a Django web app. The model contains various CharField columns. When I convert these strings into JSON using json.dumps, the strings come out as Unicode like this: "{'field': u'value'}" and so forth. However, I need to pass this to Javascript, and the jQuery parser croaks on this format. What I am ...
Does anyone readily know if using eval() and responseText (using JSON) is faster or slower than just using responseXML? I would imagine avoiding the eval() and using responseXML instead would be faster, despite the fact that you gotta write really long code to actually get the values of the XML. Thanks. ...
In brief, I'm looking for a way move complex object graphs between browser code (jQuery) and server code (ASP.NET MVC). JSON does not support object references, so standard serialization of a circular referencing object is not possible out-of-the-box. A proposed standard for JSON object references is floating about, which is currently ...

Hi, I'm quite new to python (I use python 3), and i'm trying to serialize a class with one string and two lists as members in JSon. I found that there's a json lib in the python standart but it seems that I need to manually implement a serialization method. Is there a JSon encoder where I can simply pass an object, and receive the serial...
