我在以前只有一个Devise模型的应用程序中有一些Devise的基本经验.但是,我从头开始重写它以扩展功能,在第二次迭代中,我认为最好有两个独立的用户模型(patient_user和staff_user).
我知道CanCan和Rolify,并将使用其中一个模型而不是其他模型.
我的问题是设置after_sign_in_path_for并将每个模型重定向到不同的“主屏幕”.
我已将每个模型设置为单独的after_sign_up_path,并且工作得非常好.
class RegistrationsController < Devise::RegistrationsController protected # Creating separate after_sign_up_paths for patient_user and staff_user def after_sign_up_path_for(patient_user) flash[:notice] = 'Welcome! You have signed up successfully.' privacy_agreement_path end # Add an after_sign_up path for staff_user def after_sign_up_path_for(staff_user) flash[:notice] = 'Welcome! You have signed up successfully.' dashboard_path end end
显然,after_sign_in_path_for应该在Application Controller中定义,而不是在Sessions Controller中定义.
Stack Overflow question clarifying this difference
这是我最好的尝试：
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs,you may want to use :null_session instead.
protect_from_forgery with: :exception
def after_sign_in_path_for(resource)
case resource
when patient_user
privacy_agreement_path
when staff_user
dashboard_path
end
end
end
这给出了错误：
undefined local variable or method `patient_user' for #<Devise::SessionsController:0x00000109a40e48>
如果我将案例选择条件大写,那么它似乎识别出变量,但我得到一个完全不同的错误：
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs,you may want to use :null_session instead.
protect_from_forgery with: :exception
def after_sign_in_path_for(resource)
case resource
when Patient_user
privacy_agreement_path
when Staff_user
dashboard_path
end
end
end
这给出了错误
Circular dependency detected while autoloading constant Patient_user (RuntimeError) ./app/controllers/application_controller.rb:11:in `after_sign_in_path_for'
我已经尝试了很多谷歌搜索并查看了其他各种设计和循环依赖问题,但未能找到解决办法,我想我在设计中不够好知道我在做什么.
我尝试的另一件事是在应用程序控制器中调用after_sign_in_path_for的patient_user和staff_user
#application_controller.rb
def after_sign_in_path_for(patient_user)
privacy_agreement_path
end
def after_sign_in_path_for(staff_user)
dashboard_path
end
这适用于staff_user,但是转到/ patient_users / sign_in并提供有效的用户名和密码,而是重定向到dashboard_path(而不是privacy_agreement_path).
该问题似乎集中在使用“资源”和旨在将“patient_user”帐户重定向到“privacy_agreement_path”和“staff_user”帐户为“dashboard_path”的条件语句.这适用于RegistrationsController中的after_sign_up_path,但不适用于ApplicationController中的after_sign_in_path.

编辑：
我尝试过Vapire的解决方案：
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs,you may want to use :null_session instead.
protect_from_forgery with: :exception
def after_sign_in_path_for(resource)
# check for the class of the object to determine what type it is
case resource.class
when PatientUser
privacy_agreement_path
when StaffUser
dashboard_path
end
end
end
但这启动了错误：
undefined method `staff_user_url' for #<Devise::SessionsController:0x000001047a0198> (NoMethodError)
有点谷歌搜索我找到了this discussion on Devise github,对于这是某种错误还是只是一个糟糕的实现完全缺乏共识.
我遵循建议的解决方案,即更新routes.rb
#routes.rb
devise_for :patient_users,:controllers => { :registrations => :registrations }
devise_for :staff_users,:controllers => { :registrations => :registrations }
resources :patient_users #added as bugfix
resources :staff_users #added as bug fix
uninitialized constant StaffUsersController (ActionController::RoutingError)
#controllers/staff_users_controller.rb class StaffUsersController < ApplicationController end
这给了错误
The action 'show' Could not be found for StaffUsersController (AbstractController::ActionNotFound)
#controllers/staff_users_controller.rb class StaffUsersController < ApplicationController def show end end
Missing template staff_users/show,application/show with {:locale=>[:en],:formats=>[:html],:handlers=>[:erb,:builder,:raw,:ruby,:jbuilder,:coffee]}. Searched in:
所以我也添加了该文件(只是app / views / staff_users.html.erb中的空白文件)
然后工作,但重定向到错误的页面/ staff_users / 1
所以我再次修改了控制器
#controllers/staff_users_controller.rb
class StaffUsersController < ApplicationController
def show
redirect_to dashboard_path
end
end
一切正常.这似乎是一个非常复杂的解决方案,但是我必须为PatientUsers做同样的事情,而且我已经选择了许多我不需要的备用资源路径.
编辑2：
Mandeep请求的调试器信息.

看起来完全像我预期的那样,应该表明resource.class可以正常工作而没有任何大的变通方法,但显然不是.
解
因此,只需使用If条件而非条件条件修复整个事物,不需要任何其他的东西.我不知道为什么会这样,但这是一个适当的解决方案.
#registrations_controller.rb class RegistrationsController < Devise::RegistrationsController protected # BUGFIX # https://stackoverflow.com/questions/19451881/devise-after-sign-in-path-for-works-but-not-the-other-ones # Creating separate after_sign_up_paths for patient_user and staff_user def after_sign_up_path_for(resource) # check for the class of the object to determine what type it is if resource.class == PatientUser privacy_agreement_path elsif resource.class == StaffUser dashboard_path end end end
和
#application_controllers.rb
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs,you may want to use :null_session instead.
protect_from_forgery with: :exception
def after_sign_in_path_for(resource)
# check for the class of the object to determine what type it is
if resource.class == PatientUser
privacy_agreement_path
elsif resource.class == StaffUser
dashboard_path
end
end
end
感谢Mandeep和Vapire的帮助！
解决方法
鉴于您的两个用户模型都称为PatientUser和StaffUser,您应该这样做：
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs,you may want to use :null_session instead.
protect_from_forgery with: :exception
def after_sign_in_path_for(resource)
# check for the class of the object to determine what type it is
case resource.class
when PatientUser
privacy_agreement_path
when StaffUser
dashboard_path
end
end
end
详细说明你的其他尝试：
在Devise为您登录用户之后,它只需向您的应用程序控制器调用after_sign_in_path(resource).它是否调用Devise本身提供的标准实现或自定义实现对于Devise来说不是问题.如果您自己实现它,它将为您完全做些什么.因此,如果您想对它做出反应,那么您有责任检查作为资源参数的类型.
# application_controller.rb # you implement the method once def after_sign_in_path_for(patient_user) privacy_agreement_path end # you implement it twice which means # this overrides the above method,so a call to after_sign_in_path will always # result in calling this method,no matter what type of user it is def after_sign_in_path_for(staff_user) dashboard_path end
仅仅因为您以某种方式命名参数,它就不会提供有关参数类型的信息.这不是OO编程的设计方式.
