OmniAuth动态回调URL验证特定对象而不是current_user [英] OmniAuth dynamic callback url to authenticate particular objects instead of current_user

问题描述

说我有用户和项目模型.用户和项目与HABTM相关.我的设置实际上比这要复杂一些，但是出于我的问题，我认为这可以做到.

Say I have the models User and Project. Users and projects are HABTM-associated. My setup is actually a bit more complicated than this, but I think for the purposes of my question this will do.

现在，我想使用omniauth通过Twitter，Facebook来对特定项目进行身份验证，这有什么用.我已经找到了如何定义omniauth path_prefix的方法，但是我不知道如何传递这样的变量:config.path_prefix = 'projects/:project_id/auth'，更不用说创建自定义回调URL了，例如project/:project_id/auth/twitter/callback

Now, I want to use omniauth to authenticate a particular project with Twitter, Facebook, what have you. I've figured out how to define my omniauth path_prefix, but I don't know how I could pass in a variable like so: config.path_prefix = 'projects/:project_id/auth', much less make a custom callback url like project/:project_id/auth/twitter/callback.

推荐答案

为了后代的缘故，我是这样解决的:

For posterity's sake, I solved it this way:

我在项目控制器中添加了auth方法，该方法设置了会话变量session[:auth_project_id]，然后重定向到auth/ + params[:provider].

I added an auth method to my projects controller, which set a session variable session[:auth_project_id] and then redirectes to auth/ + params[:provider].

在回调控制器authentications中，我使用@project = Project.find(session[:auth_project_id])获取了项目，创建了身份验证，然后使用session[:auth_project_id] = nil取消了会话变量的设置.

In my callback controller authentications, I got my project with @project = Project.find(session[:auth_project_id]), created the authentication, and then session[:auth_project_id] = nil to unset the session variable.
