我已经按照屏幕播放形式进行了ryan bates railscast,除非我改变我的方法,否则每件事情都会正常工作:
这
def create
omniauth = request.env["omniauth.auth"]
current_user.authentications.create(:provider => omniauth['provider'], :uid => omniauth["uid"])
flash[:notice] = "Authentication successful"
rescue Exception => e
# Just spit out the error message and a backtrace.
render :text => "<html><body><pre>" + e.to_s + "</pre><hr /><pre>" + e.backtrace.join("\n") + "</pre></body></html>"
end
到
def create
omniauth = request.env["omniauth.auth"]
current_user.authentications.create(omniauth['provider'], omniauth["uid"])
flash[:notice] = "Authentication successful"
rescue Exception => e
# Just spit out the error message and a backtrace.
render :text => "<html><body><pre>" + e.to_s + "</pre><hr /><pre>" + e.backtrace.join("\n") + "</pre></body></html>"
end
我一直在使用未定义的方法stringify_keys' for "twitter":String
,但是第一种方法都可以正常工作。这里的任何想法
答案 0 :(得分:1)
您已更改:
current_user.authentications.create(:provider => omniauth['provider'], :uid => omniauth["uid"])
为:
current_user.authentications.create(omniauth['provider'], omniauth["uid"])
您将在任何rails应用中收到此错误,因为您没有指定要为其分配值的字段。 一个例子(来自我的一个应用程序):
ruby-1.9.2-p180 :002 > User.create("a", "b")
NoMethodError: undefined method `stringify_keys' for "a":String
我认为你的意思如下:
user = User.find_by_provider_and_uid(auth["provider"], auth["uid"]) || User.create_with_omniauth(auth)
