我使用Rails 3.2.9。 当我添加的CoffeeScript代码到一个.js.coffee在文件/app/assets/javascripts目录，我得到了我所有的网页所产生的JavaScript。 问题是所有的JavaScript被包裹在：
(function() {
// my code
}).call(this);
所以我定义任何方法都没有在任何其他的CoffeeScript代码，我在其他文件写入可见。 什么是写一组可重用CoffeeScript的类和方法使用Rails的正确方法？
The simplest thing to do is to namespace all your classes. If your application is called "app" then in your initialization code before anything else happens:
// Set up the namespace.
window.app = { }
and then in all your .coffee files:
class app.Pancakes
#...
Then you'd have a global namespace and you'd reference everything through that namespace:
pancakes = new app.Pancakes
Similarly for simple functions:
app.where_is = (pancakes, house) -> ...
# And elsewhere...
x = app.where_is(...)
There are various ways of setting up and partially hiding the namespace but they're all variations on the above and simple namespacing plays nicely with the Rails asset pipeline.
此外，您还可以像这样的CoffeeScript文件中定义类：
class this.Person
constructor: (attr = {}) ->
...
通过这种方式，定义被附加到全局命名空间。
