获取有用的意见，我想传递参数在Ajax来控制器，但它总是返回错误回调，我不能没有找到原因。

Getting helpful comment, I'm trying to pass param to controller in ajax but it always returns error callback I can't not find the reason.

下面是我的code。

.html.haml

:coffee
$('input#field').change ->
    $.ajax
        url: '/posts/gaga'
        type: "GET"
        dataType: "json"
        data: { code: $('input#field').val() }
        error: (jqXHR, textStatus, errorThrown) ->
            alert "error"
        success: (data, textStatus, jqXHR) ->
            alert "success"

routes.rb中

get 'posts/gaga'

posts_controller.rb

def gaga
    @model = Model.new
    render nothing: true
end

有谁知道什么是错我的code？

Does anyone know what's wrong my code?

在此先感谢。

推荐答案

我觉得你的路线不正确。它应该被格式化这样至少有：

I think your route is incorrect. It should be formatted like this at least:

拿到上岗/加加，以岗位＃加加

不过，这可能是更多你想，如果你已经有一个的资源是什么：帖子在routes.rb中：

However this might be more what you want if you already have a resources :posts in your routes.rb:

resource :posts do
  collection do
    get :gaga
  end
end

由于那么你就可以避免重复拿到上岗/..."如果您打算增加更多的自定义操作。

Because then you can avoid repeating get "posts/..." if you plan on adding more custom actions.
