ActionController::UrlGenerationError in Devise::SessionsController#create / Trying to Create 2 Signup Access with devise

Question

我是 Rails 新手，如果以下问题可能很简单，我深表歉意，但我们将不胜感激。

我正在使用 GEM 设计。我为用户（代表交易者）和房主设置了 2 个身份验证系统（使用设计）

当用户登录时，我希望他们被定向到 users/show.html.erb 页面，当房主登录时，我希望他们被定向到 homeowners/show.html.erb

我收到的错误消息：

1. 我在 用户（商人）和房主的 application_controller.rb

2. 当我为 Homeowner 删除设计 after_sign_in_path_for 方法时 并将编码设计 after_sign_in_path_for 方法留给用户 （商人）.....当我以用户（商人）身份登录时，我没有收到任何错误 我被定向到个人资料页面（users/show.html.erb）...（副 反之亦然）。

3. 但是当我离开用户（商人）和房主的 after_sign_in_path_for 方法并以用户（商人）或房主身份登录时，我收到以下错误消息

我正在尝试为用户（商人）和房主创建两个登录访问权限

Answer 1

您不能定义 2 个具有相同名称的方法。第二种方法将覆盖第一种。

如果您查看日志，您可以看到传递了一个参数来判断用户是否是商人

"commit"=>"Tradesman login"

所以你的方法定义看起来像

def after_sign_in_path_for(resource)
  if params[:commit] == 'Tradesman login'
    user_path(current_user)
  else
    homeowner_path(current_homeowner)
  end
end
