Question

感谢阅读！问题似乎很容易解决，但我与它战斗4小时，所以：机型：

class Admin < ActiveRecord::Base
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
end

同样适用于Pupil和Teacher课程，但是课程Pupil＆lt; ActiveRecord :: Base等。

application_controller.rb

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
  before_action :authenticate_pupil!
  before_action :authenticate_admin!
  before_action :authenticate_teacher!  

end

application.html.erb

<!DOCTYPE html>
<html>
<head>
  <title>EDziennik2</title>
  <%= stylesheet_link_tag    "application", media: "all", "data-turbolinks-track" => true %>
  <%= javascript_include_tag "application", "data-turbolinks-track" => true %>
  <%= csrf_meta_tags %>
</head>
<body>

<% if notice %>
  <p class="alert alert-success"><%= notice %></p>
<% end %>
<% if alert %>
  <p class="alert alert-danger"><%= alert %></p>
<% end %>

<p class="navbar-text pull-right">
<% if admin_signed_in? %>
  Logged in as <strong><%= current_admin.email %></strong>.
  <br>
  <%= current_admin %>
  <%= link_to 'Edit profile', edit_admin_registration_path, :class => 'navbar-link' %> |
  <%= link_to "Logout", destroy_admin_session_path, method: :delete, :class => 'navbar-link'  %>
<% elsif pupil_signed_in? %>
  Logged in as <strong><%= current_pupil.email %></strong>.
  <br>
  <%= current_pupil %>
  <%= link_to 'Edit profile', edit_pupil_registration_path, :class => 'navbar-link' %> |
  <%= link_to "Logout", destroy_pupil_session_path, method: :delete, :class => 'navbar-link'  %>
<% elsif teacher_signed_in? %>
  Logged in as <strong><%= current_teacher.email %></strong>.
  <br>
  <%= current_teacher %>
  <%= link_to 'Edit profile', edit_teacher_registration_path, :class => 'navbar-link' %> |
  <%= link_to "Logout", destroy_teacher_session_path, method: :delete, :class => 'navbar-link'  %>
<% end %>

<%= yield %>

</body>
</html>

问题是，当我尝试登录时，我需要传递3次电子邮件和密码。然后我正确登录。对我来说，这是application_controller.rb和3x before_action身份验证行的问题，因为当我删除其中2个时，我正确登录。任何想法该怎么做？

修改好的，我想我已经解决了这个问题:) 在application_controller.rb中，我定义了一个名为

的新方法

认证！

def authenticate!
    if @current_user == current_admin 
        :authenticate_admin!
    elsif @current_user == current_pupil
        :authenticate_pupil
    elsif @current_user == current_teacher
        :authenticate_teacher
    end
  end

rails 4中的before_action，设计了多个用户模型
