Question

我正在尝试使用Omniauth-identity gem来创建用户，并且出于某种原因我遇到了会话错误。为什么身份甚至指向创建会话而不是创建用户？如何获取Identity以创建用户并将其重定向到正确的路径？

尝试注册新用户时出现

错误

No route matches {:action=>"feed", :controller=>"users", :id=>nil} missing required keys: [:id]

20 if user
21   session[:user_id] = user.id
22   redirect_to feed_user_path(@user), notice: "Signed in!"
23 else
24   session[:user_id] = nil
25   flash.now[:error] = 'Invalid email/password combination'

app/controllers/sessions_controller.rb:22:in `create'

的routes.rb

match '/signin',   to: 'sessions#new',         via: 'get'
match "/auth/identity/callback", to: "sessions#create", via: 'post'

sessions_controller

def create
if omniauth_env = request.env.fetch("omniauth.auth", nil)

user = Identity.find_or_create_by(email: email).user
Token.update_or_create_with_omniauth(user, omniauth_env) if omniauth_env

Answer 1

在sessions_controller中，您使用局部变量user而不是实例变量@user。

当你再调用feed_user_path(@user)时，你用nil调用它，并且该方法缺少id。

Omniauth-Identity不创建用户
