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

问题描述

我有一个表单：remote => true表示将通过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，当身份验证失败时，设计将会提高

However, when the authentication fails, devise will raise a

Completed 401 Unauthorized

并且不会显示不引人注目的JavaScript。

and no unobtrusive javascript will be rendered.

但是希望如此：

设计在flash中设置一些消息，并渲染我的.js.erb，然后我向用户显示闪光。

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

这是非常有趣但是在devise.rb中更改http_authenticatable_on_xhr到false

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

config.http_authenticatable_on_xhr = false

为我做的窍门...没有覆盖authenticate_user！方法

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

注意：我还添加了：js到导航格式

note: I also added :js to navigational formats

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