使用 Omniauth 为没有 STI 的多个模型设计 [英] Devise with Omniauth for multiple models without STI

问题描述

有没有办法在没有 STI 的情况下为多个模型配置 Devise Omniauth?

Is there any way to configure Devise Omniauth for multiple models without STI?

我们有模型学生和教授，我们不想使用 STI，但现在我们意识到设计与 Omniauth 不能很好地处理多个模型.

We have the models Students and Professors and we didn't want to use STI but now we realized that Devise with Omniauth doesn't play well with multiple models.

.rvm/gems/ruby-1.9.3-p125/gems/devise-2.1.0/lib/devise/rails/routes.rb:384:in `devise_omniauth_callback': Wrong OmniAuth configuration. If you are getting this exception, it means that either: (RuntimeError)

1) You are manually setting OmniAuth.config.path_prefix and it doesn't match the Devise one
2) You are setting :omniauthable in more than one model
3) You changed your Devise routes/OmniAuth setting and haven't restarted your server

推荐答案

我认为与其将 :omniauthable 写给单个 Student &教授模式.您应该生成第三个模型，如 Omniuser 并向其添加 :omniauthable 设置.

I think rather than writing :omniauthable to individual Student & Professor model. You should generate third model like Omniuser and add :omniauthable settings to it.

class Student < ActiveRecord::Base
  has_one :omniuser
end

class Professor < ActiveRecord::Base
  has_one :omniuser
end
