Ruby on rails 将#u重定向到'；我不能正常工作

我使用

design

并尝试做下一件事：

当用户登录/注册时，我希望通过他的角色\u id重定向他（对于某些用户，我让id为1，对于其他用户，我让id为2）

如果他的角色id为1，则将其重定向到

tasksadmin\u路径

，否则重定向到

workers\u路径

所以我尝试了以下方法：

routes.rb

：

devise_for :users, :controllers => { :sessions => 'user_sessions'} do
   get '/users/sign_out' => 'devise/sessions#destroy'
   root to: "workers#index"
end

resources :tasksadmins

resources :workers

root to: "workers#index"

class ApplicationController < ActionController::Base
    include ApplicationHelper

    protect_from_forgery
    before_filter :authenticate_user!

    rescue_from CanCan::AccessDenied do |exception|
        if current_user.role_ids == [2]
           redirect_to root_url
        else
           redirect_to tasksadmins_path
        end
    end
end

这是我的

应用程序\u控制器.rb

：

devise_for :users, :controllers => { :sessions => 'user_sessions'} do
   get '/users/sign_out' => 'devise/sessions#destroy'
   root to: "workers#index"
end

resources :tasksadmins

resources :workers

root to: "workers#index"

class ApplicationController < ActionController::Base
    include ApplicationHelper

    protect_from_forgery
    before_filter :authenticate_user!

    rescue_from CanCan::AccessDenied do |exception|
        if current_user.role_ids == [2]
           redirect_to root_url
        else
           redirect_to tasksadmins_path
        end
    end
end

class ApplicationController

DeVICE针对这种情况有特殊的方法。您可以在对的路径进行签名后覆盖。应用程序控制器

def after_sign_in_path_for(resource_or_scope)
 if resource_or_scope.is_a?(User)
  town_path
 else
  users_path
 end
end

用于的路径中的签名后的

无效，因此我在“创建”中添加了以下行：

开始时，我写道：

resource = warden.authenticate!(:scope => resource_name)

sign_in(resource_name, resource)

if current_user.role_ids == [2]
   respond_with resource, :location => workers_path
else
   respond_with resource, :location => tasksadmins_path
end

class UserSessionsController < Devise::SessionsController
    include ApplicationHelper

    def create

        resource = warden.authenticate!(:scope => resource_name)

        require "uri"
        require "net/http"

        ## get the user id from the database
        user_id = session['warden.user.user.key'][1][0];

        ## get the row by id
        user = User.find(user_id)

        # ============================
        # Ensure that a user exists
        # ============================

        code, body = http_request(Net::HTTP::Put.new("/api/v1/users/external/#{user_id}"), email: user.email);
        if code != 200
           Rails.logger.error("Unable to register user #{current_user.email} at Licensario");
        end

        sign_in(resource_name, resource)

        if current_user.role_ids == [2]
           respond_with resource, :location => workers_path
       else
           respond_with resource, :location => tasksadmins_path
       end

    end
end

然后我在“创建”函数的末尾写道：

resource = warden.authenticate!(:scope => resource_name)

sign_in(resource_name, resource)

if current_user.role_ids == [2]
   respond_with resource, :location => workers_path
else
   respond_with resource, :location => tasksadmins_path
end

class UserSessionsController < Devise::SessionsController
    include ApplicationHelper

    def create

        resource = warden.authenticate!(:scope => resource_name)

        require "uri"
        require "net/http"

        ## get the user id from the database
        user_id = session['warden.user.user.key'][1][0];

        ## get the row by id
        user = User.find(user_id)

        # ============================
        # Ensure that a user exists
        # ============================

        code, body = http_request(Net::HTTP::Put.new("/api/v1/users/external/#{user_id}"), email: user.email);
        if code != 200
           Rails.logger.error("Unable to register user #{current_user.email} at Licensario");
        end

        sign_in(resource_name, resource)

        if current_user.role_ids == [2]
           respond_with resource, :location => workers_path
       else
           respond_with resource, :location => tasksadmins_path
       end

    end
end

所以我的创建看起来是这样的：

resource = warden.authenticate!(:scope => resource_name)

sign_in(resource_name, resource)

if current_user.role_ids == [2]
   respond_with resource, :location => workers_path
else
   respond_with resource, :location => tasksadmins_path
end

class UserSessionsController < Devise::SessionsController
    include ApplicationHelper

    def create

        resource = warden.authenticate!(:scope => resource_name)

        require "uri"
        require "net/http"

        ## get the user id from the database
        user_id = session['warden.user.user.key'][1][0];

        ## get the row by id
        user = User.find(user_id)

        # ============================
        # Ensure that a user exists
        # ============================

        code, body = http_request(Net::HTTP::Put.new("/api/v1/users/external/#{user_id}"), email: user.email);
        if code != 200
           Rails.logger.error("Unable to register user #{current_user.email} at Licensario");
        end

        sign_in(resource_name, resource)

        if current_user.role_ids == [2]
           respond_with resource, :location => workers_path
       else
           respond_with resource, :location => tasksadmins_path
       end

    end
end

我尝试了您建议的方法，结果是：在该操作中多次调用了Render和/或redirect。请注意，您只能调用render或redirect，每个操作最多只能调用一次。另外请注意，重定向和渲染都不能终止操作的执行，因此，如果您想在重定向后退出操作，则需要执行类似“重定向到（…）并返回”的操作。我不知道为什么重定向太多。。我写道：如果当前的用户角色ID=[2]重定向到根目录url，否则重定向到任务ADMINS\U路径结束你不应该重定向到这个路径。您应该只给Desive url以重定向。设法改变你的方向。方法的路径中的签名后返回url。如果当前用户角色ID==[2]根url else tasksadmins\u路径结束，则为（用户）在路径中签名后定义请参见前面的注释。使用Desive中的标准方法比钩住会话控制器要好得多。
