Question

我尝试使用omniauth从Facebook返回的uid更新我的Devise模型Vendor。这不是登录或注册我的应用程序，而是与Facebook集成，如果这是有道理的。我试图使用这种模式：

class Vendors::OmniauthCallbacksController < Devise::OmniauthCallbacksController
    def facebook
        @vendor = current_vendor
        uid = request.env["omniauth.auth"]["uid"]
        puts uid
        @vendor.update_attributes(:uid => uid)
        redirect_to vendors_dashboard_path
    end
end

当此方法尝试更新属性时，我一直收到302 Found。当我puts uid时，我看到正确的uid被返回，但是params哈希由state和code属性组成。我对这种回调方法有什么不了解？

服务器日志：

  Parameters: {"code"=>"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", "state"=>"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"}

您被内置的批量分配保护阻止，尝试仅使用update_column更新列，看看是否能解决您的问题。由于AR与它的模型基本相同，因此提交不会将任何内容写回数据库。

尝试以下方法：

class Vendors::OmniauthCallbacksController < Devise::OmniauthCallbacksController
    def facebook
        @vendor = current_vendor
        uid = request.env["omniauth.auth"]["uid"]
        puts uid
        @vendor.update_column(:uid, uid)
        redirect_to vendors_dashboard_path
    end
end

从facebook omniauth响应中坚持uid - 设计
