Devise，OmniAuth& Facebook：“未找到。认证passthru“。 [英] Devise, OmniAuth & Facebook: "Not found. Authentication passthru."

问题描述

试图跟随 https://github.com/plataformatec/devise/wiki/OmniAuth:-概述，我被困了。

Trying to follow along with https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview and I'm stumped.

我有 config.omniauth：facebook，ENV ['FB_APP_ID']，ENV ['FB_APP_SECRET'] 在我的config / initializers / devise.rb中， devise_for：users，：controllers => {：omniauth_callbacks =>我的routes.rb中的users / omniauth_callbacks} ，并定义了一个OmniAuthCallbacks控制器。

I've got config.omniauth :facebook, ENV['FB_APP_ID'], ENV['FB_APP_SECRET'] in my config/initializers/devise.rb, devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" } in my routes.rb, and an OmniAuthCallbacks controller defined.

当我访问 user_omniauth_authorize_path（：facebook）时，我得到：
未找到。认证passthru。我不知道接下来该怎么做。我没有使用路由游戏，所以我不相信我需要定义一个passthru方法，但是这样做只是给了我一个404。

When I visit user_omniauth_authorize_path(:facebook), I get: Not found. Authentication passthru. I'm not sure what to do next. I am not using route globing, so I don't believe I need to define a passthru method, but doing so just gives me a 404.

推荐答案

还要确保你已经添加了一个路径到OmniauthCallbacksController：

Also make sure you have added a route to the OmniauthCallbacksController:

devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }

，并且您已将更新添加到用户模型中的设计声明：

and that you have added the update to the devise declaration in your User model:

devise :omniauthable, :omniauth_providers => [:facebook]
