-class Hash
-  # Returns a JSON string representing the hash.
-  #
-  # Without any +options+, the returned JSON string will include all
-  # the hash keys. For example:
-  #
-  #   { :name => "Konata Izumi", 'age' => 16, 1 => 2 }.to_json
-  #   # => {"name": "Konata Izumi", "1": 2, "age": 16}
-  #
-  # The keys in the JSON string are unordered due to the nature of hashes.
-  #
-  # The <tt>:only</tt> and <tt>:except</tt> options can be used to limit the
-  # attributes included, and will accept 1 or more hash keys to include/exclude.
-  #
-  #   { :name => "Konata Izumi", 'age' => 16, 1 => 2 }.to_json(:only => [:name, 'age'])
-  #   # => {"name": "Konata Izumi", "age": 16}
-  #
-  #   { :name => "Konata Izumi", 'age' => 16, 1 => 2 }.to_json(:except => 1)
-  #   # => {"name": "Konata Izumi", "age": 16}
-  #
-  # The +options+ also filter down to any hash values. This is particularly
-  # useful for converting hashes containing ActiveRecord objects or any object
-  # that responds to options in their <tt>to_json</tt> method. For example:
-  #
-  #   users = User.find(:all)
-  #   { :users => users, :count => users.size }.to_json(:include => :posts)
-  #
-  # would pass the <tt>:include => :posts</tt> option to <tt>users</tt>,
-  # allowing the posts association in the User model to be converted to JSON
-  # as well.
-  def to_json(options = {}) #:nodoc:
-    hash_keys = self.keys
-
-    if except = options[:except]
-      hash_keys = hash_keys - Array.wrap(except)
-    elsif only = options[:only]
-      hash_keys = hash_keys & Array.wrap(only)
-    end
-
-    result = '{'
-    result << hash_keys.map do |key|
-      "#{ActiveSupport::JSON.encode(key.to_s)}: #{ActiveSupport::JSON.encode(self[key], options)}"
-    end * ', '
-    result << '}'
