similar to: rails removes newlines and spaces from ajax requests

Could someone please demonstrate the code to send both json (or xml) AND javascript (to be executed) in a single Ajax request? Is this even possible? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hello. I am building full-ajax back-end, which consits of many quite big partials. As the system grows up, performance is problem. After every click, partial is refreshed, if needed. I am now at 0.5 sec / request. I tried to simply disable ajax and the result was quite suprising: the same page is rendered over 2x faster. I update 80% of page in case of ajax. (Please dont tell: dont use ajax when

Hi, i have a "place" model with 2 columns (id, name). I''m calling an external api which gives me data to create a new place object. I would like to add the address from the external place to the place object and render it as a json result, without storing it in the database. i don''t get any errors, but the address never shows up within the json output. i''ve

I''m looking for a way to subclass active record (I''ll refer to the subclass I want to create as NewActiveRecord) so that I can call different methods on a save or destroy action on all models which sub class NewActiveRecord I dont want to use before_save or any of the other regular call back methods as I want to be able to use these call backs in the models which subclass

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 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

Am i a total idiot to try and parse out a rails object for javascript in this way? <% for i in interface_items[0].attributes %> var <%= i[0] %> = "<%=h( i[1] )%>" <% end %> Am I missing something really obvious?

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

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''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

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 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

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

Originally posted on github, reported to the right place. I would like to open a discussion about how `to_json` and `as_json` operates in Rails from a performance standpoint. I''m using Rails 3.2 but this issue applies to almost all versions of Rails. Our use case presents the challenge in sending out potentially large JSON (or XML, but we''ll focus on JSON rendering here)

I''m trying to write a helper method similar to attr_accessible but instead it will be used to whitelist which attributes are available for serialization (attr_serializable). My first attempt at this was to override serialized_hash and modify the :only option to include nothing but serializable attributes. I''m facing a problem when nested models are ''included''

Hi, I''m using prototype within ruby on rails. One limitation I''d like to overcome is the restriction of beeing able to update just one html elements content using from_remote_tag or link_to_remote. AFAICS this is just a restriction of the form_remote_tag/link_to_remote implementation and it''s underlying Ajax.Updater class. Right? In theorie there should be no problem,
