Question

我在NoMethodError的{{1}}行动中收到了new。

我的视图中似乎正在访问表单的business_controller对象，然后发生错误：

@business

这是我的新方法：

undefined method `businesses_path' for

我的路线是：

def new
  if Business.where(:user_id => current_user.id).first.blank?
    @business = Business.new
  else
    redirect_to user_businesses_path(current_user.id)
  end
end

mind.blank的建议更改

resources :users do resources :businesses member do get 'account' post 'payment' put 'update_password' get 'membership' end end

before_filter :check_if_user_has_business, :only => :index

Answer 1

您有路线businesses_path还是只有user_businesses_path？如果您只有第二个，那么您应该在表单中指定该URL：

<%= form_for @business, url: user_businesses_path do |f| %>

此外，如果您设置了正确的关联，那么您可以按如下方式编写if语句：

if current_user.business.nil? # since it's a has_one association

以下是我的写作方式：

Class BusinessesController < ApplicationController
  before_filter :check_if_user_has_business, only: :new

  def new
    @business = Business.new
  end

  private

  def check_if_user_has_business
    redirect_to user_businesses_path(current_user) if current_user.business
  end
end

控制器#new中的NoMethodError - 未定义方法
