轨道发送了错误的内容类型的Ajax响应 [英] rails sending the wrong content-type in ajax response

问题描述

我一直在挣扎可怕的一天有以下问题更好的一部分：

I have been struggling terribly for the better part of the day with the following problem:

• 在我有一个Rails 3.1的应用程序 - 运行正常
• 我想一些Ajax添加到它

不过，无论我怎么努力，Rails的坚持在响应首部发送了错误的内容类型。

However, no matter what I try, Rails insists on sending the wrong content-type in the response header.

#the form    
= form_for @signup, :url => '/signup', :remote => true do |f|
    = f.text_field :email, :class => 'email', :size => 26
    = f.submit 'Notify me'

#In the controller
def create
  respond_to do |format|
    format.js { render :content_type => 'text/javascript', :layout => false}
  end
end

#the JS file: create.js.erb
alert('HI!');

这是行不通的，而我认为它应该。检查与萤火虫服务器响应它告诉我响应头具有一个内容类型的的text / html 。我想，这就是为什么它不工作（作为一个新生成的应用程序，使用同样的jQuery护栏宝石也可以用文/ JavaScript的头响应。

This is not working, while I think it should. Inspecting the server response with Firebug it tells me the response header has a content-type of text/html. I figure this is why it isn't working (as on a newly generated app, using the same jquery-rails gem it responds with a text/javascript header.

服务器的说的它与JS响应：

The server says it's responding with JS:

Processing by SignupsController#create as JS

但由于某种原因拒绝发送正确的头。我失去了去哪里寻找下一个。

But is somehow refusing to send the correct header. I am lost on where to look next.

任何帮助或方向是在哪里寻找下一个会是极大的AP preciated！ 欧文

Any help or direction as to where to look next would be greatly appreciated! Erwin

推荐答案

确定找到了解决办法，

因此​​，在应用程序控制器的after_filter被重写内容类型。他们在里面了处理。因此，它是覆盖我的声明。

So an after_filter in application controller was overriding the content-type. And they are processed inside out. So it was overwriting my declarations.
