similar to: Serialized JSON object importation

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

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

I''m doing a request from a Rails app to another Rails app with ActiveResource. When the format on ActiveResource is XML: Content.find(:all)[0,2].map(&:attributes) => [ {"updated_at"=>Mon Apr 27 15:04:32 UTC 2009, "url"=>"www.google.com", "id"=>1, "created_at"=>Mon Apr 27 15:04:32 UTC 2009},

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 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

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:

Rails 3.1.3 I have changed a regular scaffold action a bit so that it can save using ajax. All I needed to do was adding ":remote => true" in <div id="script_new"> <%= form_for script, :remote => true do |f| %> <!-- HERE!!! --> <%= f.hidden_field :video_id %> <%= f.text_field :text %> <%= f.submit "save" %>

Hi all, i got a record from my project server side database, like this : @user = User.find 1 then i cover @user to json format: @user.to_json the result : "created_at": "2009-01-28T12:29:32Z" what''s the T and Z of created_at field ? but i change Rails 2.2.2 to Rails1.1.6, I got : "created_at":

Title: Nested serialization with to_json and to_xml with array and hash element class Person < ActiveRecord::Base has_one :address has_one :job def office() return "Executive_Suite" end end class Address < ActiveRecord::Base belongs_to :person end class Job < ActiveRecord::Base belongs_to :person has_one :paygrade def Title return "Engineer" end end

hi, I have json string in json request. i want to update the database using that string. how can i do that? There would be a multipal object in this string. sample string is:

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

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

Hello, Anybody help me out? I done googled it good and didn''t find anything (which should mean that I''ve done something wrong). Not much code to talk about here, quite simply I have an attribute that is serialzied and when I update it, irb shows the object and my methods run on it as it were indeed so. Though when I reload it changes the data to a string. Not yaml, just one

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, 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 =>

hi , all under rails 2.0 aotianlong@aotianlong:~/workspace/killer$ ruby script/console Loading development environment (Rails 2.0.1) >> {:user=>"aotianlong"}.to_json => "{\"user\": \"aotianlong\"}" >> user = User.find :first => #<User id: 1, uname: "aotianlong"> >> user.to_json =>

Hi, In short: I can do following: user.to_xml(:root => "xml_user" ) But not following: user.to_json(:root => "json_user") JSON serializer for AR doesn''t allow us to specify "root" option unlike XML serializer. JSON serializer always uses model name as the root if class attribute include_root_in_json is set to true. I''ve added a patch which

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

Just some quick cleanup and documentation. Remove obsolete ActiveSupport::JSON::Variable - http://dev.rubyonrails.org/ticket/9969 Add documentation for Hash#to_json and Enumerable#to_json - http://dev.rubyonrails.org/ticket/9970 Please review :) Thanks!
