Accessing ActiveRecord objects in javascript
# put this in lib/active_record/json.rb require 'json/lexer' require 'json/objects' module ActiveRecord module Json # :nodoc: DEFAULT_CONVERSIONS = { Time => [:to_s, :db] } def to_json(conversions = {}) conversions = DEFAULT_CONVERSIONS.merge(conversions) self.attributes.keys.inject({}) do |hsh, key| value = self.send(key) hsh.merge(key => conversions[value.class] ? value.send(*conversions[value.class]) : value.to_s) end.to_json end end end # in environment.rb do #require "#{RAILS_ROOT}/lib/active_record/json" #ActiveRecord::Base.class_eval { include ActiveRecord::Json }
Doing something like
<%= var post = @post.to_json %>in a javascript snippet should allow you to use the basic AR attributes such as post.title, post.summary (using the Weblog analogy). You could also pass the json bits to a javascript function.
