试图在水豚上分配给只读属性

时间：2018-06-26 02:25:38

标签： ruby-on-rails angularjs ruby-on-rails-4 capybara poltergeist

我正在将一个rails 3.2应用更新为rails 4.2.10，我已经完成了几乎所有工作，单元测试和集成测试都通过了。

我在功能测试中遇到了一些问题，正在使用capybara 3.3.0和poltergeist 1.18.1，这使我在visit '/'上出现了错误

我在Stack上查看了很多有关试图分配给只读属性的问题，但这些问题都不适用于我的情况，

这是我精简的规格文件

require 'vcr'

Capybara.default_max_wait_time = 10

feature "Create something"  do
  include SpecHelpers
  include Acceptance

  before do
    setup_database
  end

  after do
    teardown_database
  end

  scenario "Creating a Consignment", :js => true do

    puts "Running with #{Capybara.current_driver}"

    VCR.use_cassette('cassette_name.yml') do      
      page.driver.resize(1000,2200) unless Capybara.current_driver == :selenium
      visit '/'
      expect(page).to have_content 'EMAIL'
      expect(page).to have_content 'PASSWORD'


    end
  end

end

在进行一些调试后，发现尝试将$render设置为函数时，会从angularjs-bootstrap-datetimepicker包抛出错误，

var ngModelController = $element.controller('ngModel')

var configuration = createConfiguration()
$scope.screenReader = configuration.screenReader

// Behavior
$scope.changeView = changeView
ngModelController.$render = $render --> in this line
