通过JS在滑轨设计注册＃更新 [英] Devise Registration#update via JS in Rails

问题描述

我想通过设计来更新用户模型AJAX和具有设计与适当的JavaScript文件。

I'm trying to update the User model through Devise with AJAX and have Devise respond with the proper javascript file.

我要远程提交表单的注册＃更新操作，但是这不工作从制定默认响应，它使用从RegistrationsController如下：

I want to submit the form remotely to the registrations#update action, but this isn't working with the default response from Devise, which uses the following from the RegistrationsController:

respond_with resource, :location => after_update_path_for(resource)

以上设法重新渲染update.js.erb文件的缺省路由来代替。我能够覆盖行动，并把它与下面的变化工作：

The above tries to redirect to the default route instead of rendering the update.js.erb file. I am able to overwrite the action and have it work with the following change:

respond_to do |format|
    format.html
    format.js
 end

不过，这似乎很蛮力因为我重写了整个行动。有一个简单的办法制订知道该用JavaScript回应，而不是做它的默认重定向？

But, this seems very brute force as I'm overriding the entire action. Is there a simple way for Devise to know to respond with javascript instead of doing its default redirect?

推荐答案

只是有一条线添加到RegistrationsController使设计明知的respond_to HTML和JS。

Simply had to add a line to the RegistrationsController so that Devise knows to respond_to both html and js.

class RegistrationsController < Devise::RegistrationsController
  respond_to :html, :js
end

在阅读关于如何respond_with真正帮助。对很好的链接：
