Ruby on rails 轨道&x2B；设计：用户注册中未定义的局部变量#编辑 更新：

我需要将我的控制器代码放在上面super，就像这样，然后我可以访问视图中的@company实例变量：

用户注册控制器：

class UserRegistrationController < Devise::RegistrationsController
  before_action :configure_permitted_parameters
  skip_before_filter :load_customer_access, only: [:new, :create]

    devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:first_name, :last_name, :current_password, :password, :password_confirmation, :email) }
  end

  def edit
    @customer = current_user.customer
    @company = Company.find_by_domain(User.get_domain(@customer.email))

有趣的是，当我在视图中执行

操作时，不会显示公司名称（尽管ID为2，名称为“Ryan Drake”），并在视图中显示ok。当我执行

时，它抛出“nil:class的未定义方法'id'

任何关于以最简单的方式从Edit Account Deviate视图访问公司ID的指导，我都可以将其作为一个参数传递并点击该方法，这将是非常棒的

在您显示的代码中，有一个end和一个if，我认为您可能在错误行之前关闭了“each”循环，因此找不到“company”变量

编辑：

我看到两个潜在问题：

它肯定是

编辑公司用户路径（@company）

中的

@company

。如果 它不起作用，是否显示相同的错误？请出示

我想你可能在化名里设计路线 “编辑公司用户路径”，但我不知道你是如何组织的 你的资源。如果您将公司嵌套在用户下，则 默认的路由如下 编辑公司用户路径（@公司，当前用户）。运行

rake路由

if 你得到一个路由错误

---

粘贴您的_edit_account.html.erb查看代码从您调用的部分_edit_帐户的位置？从哪个文件呈现该部分？designe/edit.html.erb

您是否尝试过此

编辑公司用户路径（@company）

这里有两种情况：一种是表单，它需要一个结束标记，另一种是基于访问的条件：

。除非我错过了什么，否则我不会关闭每个循环？请更清楚地指出。@RyanDrake请粘贴完整的公司索引视图，以便我们可以看到问题。完成！好了：）嘿，普西，好吧，我刚刚更新了它，因为我现在得到了一个新的错误。请看编辑后的屏幕截图：）我也添加了我日志的屏幕截图，以便看到它正在打印@company ID。
