Devise的默认行为应该是在登录后将用户发送到根路径。我没有做到这一点，而只是再次渲染登录页面。它正在记录用户。它只是没有正确重定向。

我相信你会收到验证错误，基于日志中的回滚：

可能是由您的用户模型上的某些验证引起的？
确保在应用程序布局中呈现这两个flash消息键，因为这是设计将写入的内容：
flash[:notice]和flash[:alert]
旁注：
def configure_permitted_parameters
added_attrs = [:username, :email, :password, :password_confirmation, :remember_me, :admin]
devise_parameter_sanitizer.permit :sign_up, keys: added_attrs
devise_parameter_sanitizer.permit :account_update, keys: added_attrs
end
上面的代码对我来说似乎很粗略，也许不是问题？ :admin :sign_up可能不应列入白名单，也许我错了？也许不是account_update没有验证用户是管理员 - 但我没有任何背景，所以也许我不在基地。
Devise的初始化程序已经有一个用于验证电子邮件格式的REGEX。从用户模型中删除验证可以解决问题。模型中的验证为Devise提供了一个无声错误，导致它重新呈现登录页面，即使它已成功签名用户，而不是在登录后将用户重定向到根路径。

尝试将其添加到ApplicationController.rb：
def after_sign_in_path_for(resource)
root_path
end
