如何处理设备的authenticate_user！用ajax调用? [英] how to handle devise's authenticate_user! with ajax call?

问题描述

我有一个带有 :remote => true 的表单，这意味着它将通过 ajax 提交.

I have a form with :remote => true which means it will be submitted through ajax.

在控制器中，我有这样的代码:

In the controller, I have such code:

before_filter: authenticate_user!, :only => [:create]

因为我只允许确认的用户创建资源.

For I only allow confirmed user to create resource.

但是，当认证失败时，devise 会引发一个

However, when the authentication fails, devise will raise a

Completed 401 Unauthorized

并且不会呈现不显眼的 javascript.

and no unobtrusive javascript will be rendered.

但我希望事情是这样的:

But I hope things goes like this:

设计在flash中设置一些消息，并渲染我的.js.erb，然后我向用户展示flash.

devise set some messages in flash, and render my .js.erb, then I show the flash to users.

如何实现?

推荐答案

很有趣但是在 devise.rb http_authenticable_on_xhr 中更改为 false

It is quite funny but change in devise.rb http_authenticatable_on_xhr to false

config.http_authenticatable_on_xhr = false

帮我解决了这个问题......没有覆盖authenticate_user！方法

did the trick for me... without overriding authenticate_user! method

注意:我还在导航格式中添加了 :js

note: I also added :js to navigational formats

config.navigational_formats = [:"*/*", "*/*", :html, :js]
