rails设计after_sign_up_path_for未定义的方法`subdomain'

Question

我尝试在成功注册到各自的子域后重定向用户。我在application_controller中输入了以下代码。

application_controller.rb

protected

def after_sign_in_path_for(resource)
  redirect_to root_url(subdomain: @users.subdomain)
end 

我收到以下错误

NoMethodError in Devise::SessionsController#create
undefined method `subdomain' for nil:NilClass

Extracted source (around line #10):


def after_sign_up_path_for(subdomain)
  redirect_to root_url(subdomain: @users.subdomain)
end

Devise中的NoMethodError :: SessionsController #create undefined方法   `子域＆＃39;为零：NilClass

@users是nil，因此Rails会发出错误。当您使用Devise时，可以使用User访问 Devise模型（resource）实例。

def after_sign_in_path_for(resource)
  redirect_to root_url(subdomain: resource.subdomain)
end

您也可以使用current_user

def after_sign_in_path_for(resource)
  redirect_to root_url(subdomain: current_user.subdomain)
end
