Active Jax

一个有意思的Rails插件Active Jax，它使用Prototype来做JavaScript与ActiveRecord的Bridge

安装：

ruby script/plugin install http://svn.simpltry.com/plugins/active_jax

使用例子：

# Rhtml:
<%= active_jax_include %>

# Ruby Model:
class Author < ActiveRecord::Base
  active_jax

  def find_by_name(n)
    find(:all, :conditions => {:name => n})
  end
end

# Java Script:
ActiveJax.Author.find_by_name("Nicholas Schlueter").
  each(function(author) {
    alert(author.name);
  });

例子2：

# Ruby Model:

class Author < ActiveRecord::Base
  active_jax :include => :publisher, :excluded_columns => :email

  belongs_to :publisher

  def find_by_name(n)
    find(:all, :conditions => {:name => n})
  end
end

# Java Script:
ActiveJax.Author.find_by_name("Nicholas Schlueter").
  each(function(author) {
    alert(author.publisher.name);
  });
