similar to: ActiveSupport JSON working?

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

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?

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

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 =>

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:

Hi, How do I make an image that is a clickable link the rails way? Is there a view helper for this? Thanks, Peter

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''m really glad the JSON changes got in, many thanks to all involved, committers and contributors alike :). But there''s still one feature that''s missing to achieve feature parity between the JSON and XML encoding/conversion. And that is the abililty to say in your controller: @authors = Author.find(:all) render :json => @authors.to_json(:only => :name)

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

I''m using [acts_as_commentable_with_threading](http://github.com/elight/acts_as_commentable_with_threading/), and it worked fine until I tried to overwrite the to_json function to include more details about the associated user. Here''s part of the comment class (which was originally defined in the plugin, but I moved it to the models folder, a move which seems not to affect the

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, What is the simplest way to validate a positive integer? validates_numericality_of :foo, :integer_only => true how do I add the positive part? Do I need another validation statement for pattern matching or do I have to write a validate() funciton for my model? Thanks, Peter

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

Hi, I am having a problem saving a new model that has an associated child model. If a new ticket is being created and will have one comment to go with it then I tried this in my action @ticket = Ticket.new(params[:ticket]) @comment = Comment.new(params[:comment]) @ticket.comments << @comment if @ticket.save @notice = "Ticket added. Thanks for

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

Hi, A store front a customer wants to GET /product/5/show. But for the application this is really GET /cart_item/new/5 or even better /cart_item/new?cart_item[product_id]=5 When the customer clicks add_to_cart they POST /product/5/show so that the url doesn''t confuse the user when any validation errors occur. But for the applicaiton this should be POST

Hi, I''m interested in using a currency conversion web service in my rails app. Does anyone have a free service that they use and like? I found this one http://www.webservicex.net/WS/WSDetails.aspx?CATID=2&WSID=10 I''ve tried to make a simple, plain Ruby script to connect to this and get a conversion rate without success. How do I integrate a webservice into my rails app? I

Hi, I''ve read the Agile Rails book''s chapter on ActionMailer a few times. Seems pretty straight forward. Unfortunately I can''t get my application to actually send mail. I uploaded my application to the web server and tried to get a mail message sent. Nothing happened. I looked in the log file and it says Sent mail: From: service@freedomkilts.com To:

I have a Flash application that is sending JSON data to a Rails app. I want to be able to read the JSON from the controller. Does anyone know where I can go to figure this out? I''ve Google''d around but can only find instances of converting to JSON, not the other way. Example: Flash -> Sends JSON -> Rails Controller receives JSON and converts it to a class -- Posted

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
