similar to: How does Rails respond to Ajax with JSON?

I installed the JSON gem because I wanted the JSON parser. Before installing the JSON gem, overloading worked fine. Before I remove it, I''d like to see if anyone has an idea of what is going on. It''s the only JSON parser I''m aware of, so it would be a bummer if it didn''t work. After installing, if I overload the to_json method in the class, it gives me the

The way Rails handles root nodes in JSON and XML serialization is inconsistent. This has been discussed before: https://rails.lighthouseapp.com/projects/8994/tickets/2584-232-activeresource-json-doesnt-send-parameters-with-root-node This seems mostly taken care of with ActiveModel::Base.include_root_in_json, especially if/when it ends up in ActiveResource. However, there is also the issue of how

Hey, I''ve tried every trick I can find, yet I''m still unable to get the json gem and ActiveSupport to play nice. No matter in which order I load json and active support, I still end up with: NoMethodError: undefined method `[]'' for #<JSON::Ext::Generator::State:0x104b7fac0> I''m trying to use the JSON object directly, *not* as a ActiveSupport backend:

Hey there I was scratching my head over why my application breaks when I run on a local server but works on my remote server. It turns out that my local server is Rails 2.0.2 and my remote server is 1.2.3 and I expect the tag "attributes" to be passed with a json stream, before parsing. Unfortunately, this was dropped in 2.0.2. Is there any documentation on this? Any way to get it back?

Hi, I am trying to convert a hash to JSON using ActiveSupports built in .to_json. I am doing similar to the example below but are there certain strings that could go in place of ''bar'' or ''rez'' that will break the to_json method? I am using a very long string from rjs output in place of ''bar''. Perhaps .to_json is not ready yet? Thanks, Peter

I''d really like to see just 2 more functional changes to the JSON serialization/encoding before we get to Rails 2.0. First, and I think this is really crucial because without it all the efforts to output JSON from ActiveRecord objects would have been half in vain, is to allow us to do this in controllers: @authors = Author.find(:all) render :json => @authors.to_json(:only =>

Could someone please demonstrate the code to send both json (or xml) AND javascript (to be executed) in a single Ajax request?

Hi everyone, I''m writing a lightweight AJAX application using Rails on the server side as a RESTful web service provider. I need the web service to support both JSON and XML I/O. Outputting data in XML and JSON is easy (using to_xml and to_json), and it''s also easy to do XML input as Rails does it for you automatically. Is it possible to somehow have the same automatic parsing

Hi, I''ve done AJAX calls to Rails'' Controllers before yet never required to generate a response back to the view. In this respect, I have tried to keep it moronically simple and just add a node to see that it works, yet the response doesn''t come through / isn''t interpreted as it should. Long story short, code : // Have to use Mootools to integrate a

I am using Rails 2.0.2 and trying to use to_json to generate json. I notice several problems. 1) datetime field such as created_at mapped to "created_at": {} 2) :except does not work, @post.to_json(:except => [:created_at, :updated_at] still gives me "created_at": {}, "update_at": {} 3) problem with escaped char mapping: ''<'' mapped to

Hello from a Ruby on Rails beginner! I''ve been trying to pass some data to a variable in Javascript by using json. Seems like the Javascript variable doesn''t receive the data correctly. This is the code in controller. @courses variable find the data from database. class CoursesController < ApplicationController def index @courses = Course.find(:all) end end This

Hello all, I have a script that uses a Ajax.Updater call to update the contents of a DIV. The code being inserted includes a javascript function, which is "called" by onClick event elsewhere in the HTML. The page initially works fine in that the DIV gets the right content, the Javascript inserted works fine. The problem I have is that if I call the Ajax.Updater again then the

Hello list! I am taking my first steps with AJAX and decided to give prototype a try. - I add a reference to the script to my page - Then somewhere near the bottom of the page I fire up: new Ajax.Request(''ws_adrestype.php'', { method:''get'', requestHeaders: {Accept: ''application/json''}, onSuccess:

Please check out this ticket (which would explain almost everything): http://dev.rubyonrails.org/ticket/8762 So basically, Rails to_json methods produces invalid JSON out of the box as it doesn''t quote all hash keys. This is valid JSON: { "id": 6589, "code": "SIN", "name": "Singapore" } This is not (Rails'' JSON encoders

Hi all, I''m working on a Backbone.js single page app with Rails 3.1, and in an attempt to save on HTTP requests, I want to embed initial data set in a HTML document that is sent back to the browser after successful login. I was thinking I can simply convert my ruby object to JSON, then HTML escape resulting string of JSON, and then use that as a value for JavaScript variable. Something

I tried to implement the "Rendering JSON in actions" example from http://wiki.rubyonrails.com/rails/pages/HowtoGenerateJSON : @headers["Content-Type"] = "text/plain; charset=utf-8" data = { :foo => ''bar'', :etc => ''rez'' } render :text => data.to_json When I try to decode this in javascript with

In my test functional test I have this method def post_json (data)

Hello, ActiveSupport::JSON::Variable.to_json is the only to_json without an "options" parameter. Is this intended? For example, this code in a .rjs page[@user.dom_id].visual_effect :drop_out, :afterFinish => ActiveSupport::JSON::Variable.new("foo") fails with ActionView::TemplateError: wrong number of arguments (1 for 0) On line #7 of
