我无法使用像user_signed_in这样的设计助手？或任何其他有此宝石的人。我的堆栈跟踪和错误如下。有没有人有工作的解决方案？我之前从未遇到过这个问题。我正在开展一个大型项目，我需要将API包含在移动设备的整体应用基础架构中。我注释掉了设计身份验证令牌路由，看看它们是否是导致问题的原因。无济于事，我现在无法对项目本身做任何事情;由于被锁定在Devise路线之外。

如果您以前使用过bcrypt，请确保删除在应用程序控制器（current_user，login，auth）中手动创建的某些方法，以确保它与设计提供的方法不冲突。
检查会话控制器内部，您的进程/运行登录用户方法如何，下面是为登录用户创建会话的示例代码
class SessionsController < ApplicationController
def create
user = User.find_by_username(params[:session][:username])
if user && user.authenticate(params[:session][:password])
login user
end
end
...
end

避免将devise_token_auth与设计基础gem冲突。需要对您的API进行容器化，并使其远离普通控制器。
例如，下面：
# controllers/api/v1/application_controller.rb
module Api
module V1
class ApplicationController < ApplicationController
skip_before_action :verify_authenticity_token
include DeviseTokenAuth::Concerns::SetUserByToken
end
end
end
API控制器包含DeviseTokenAuth关注点，用于在自己的域中管理应用程序。它派生自原始的ApplicationController。
现在，在原始的Application Controller中。您只需验证是否正在使用API控制器。
class ApplicationController < ActionController::Base
protect_from_forgery with: :exception, if: :verify_api
def verify_api
params[:controller].split('/')[0] != 'devise_token_auth'
end
end
整个想法是重定向应用程序的每个流，具体取决于所需的基础架构部分。我希望这个解决方案能够贯彻始终。我也希望宝石的制造商能够采取更稳定的方法。
