Question

我有一个帮助器，可以确保用户有权查看页面，并在用户没有权限时重定向：

module PermissionsHelper
  def require_permission(permission_attribute_name)
    return if current_or_guest_user.role.send(permission_attribute_name)
    redirect_to current_or_guest_user.role.landing_page,
                notice: 'You do not have sufficient permissions'
  end
end

方法current_or_guest_user是我在另一个帮助器中使用的方法，它返回当前用户，或者如果没有当前用户则创建并返回一个guest虚拟机。

我的规格如下：

require 'rails_helper'

RSpec.describe PermissionsHelper, type: :helper do
  describe 'requiring permissions' do
    let(:test_user) { create :customer }

    it "redirects the user to the user's landing page if the user doesn't have permission" do
      allow(helper).to receive(:current_or_guest_user) { test_user }
      require_permission(:view_admins)
      expect(response).to redirect_to test_user.landing_page
    end
  end
end

我收到了这个错误：

PermissionsHelper

    redirects the user to the user's langing page if the user doesn't have permission (FAILED - 1)

编辑：我尝试将allow更改为allow_any_instance_of，现在我收到此错误：

使用此规范：

it "redirects the user to the user's langing page if the user doesn't have permission" do
  allow_any_instance_of(helper).to receive(:current_or_guest_user) { test_user }
  require_permission(:view_admins)
  expect(response).to redirect_to test_user.landing_page
end

我明白了：

Failure/Error: allow_any_instance_of(helper).to receive(:current_or_guest_user) { test_user }
     NoMethodError:
       undefined method `ancestors' for #<#<Class:0x007fe5d19a9a98>:0x007fe5d19a1668>

$resultado = mysql_query($sql);

仅适用于静态方法。由于助手中的方法是实例方法，因此您需要使用

allow

编辑：

以下代码段在我的一个项目中失败（使用'helper'变量）

allow_any_instance_of

但是，使用完整的类名称可以正常工作（至少为了测试方法模拟）

allow_any_instance_of(helper).to receive(:paginate).and_return('asdf')

无法在我的帮助程序规范中存根current_or_guest_user
