当我对使用ruby的特定单词之间包含的文本感兴趣时,我想知道如何继续.例如.

@var = "Hi, I want to extract container_start ONLY THIS DYNAMIC CONTENT container_end from the message contained between the container_start and container_end "

现在我想从字符串中提取CAPITALIZED内容,即动态但始终包含在两个容器中(container_start和container_end)

我正在使用茉莉来测试我的角度控制器..then(successCallback, errorCallback) 虽然它在实时功能的基础上工作得很好但是我很困惑如何写一个间谍来返回一个错误,因为它总是被捕获的错误和成功successCallback()

以下是控制器: -

angular.module('myApp')
.controller('LoginCtrl', function ($scope, $location, loginService, SessionService) {
    $scope.errorMessage = '';

    $scope.login = function () {

      var credentials = {
          email: this.email,
          password: this.password
      };

     SessionService.resetSession();
     var request = loginService.login(credentials);

     request.then(function(promise){ //successfull callback
        if (promise['status'] === 200){
             //console.log('login');
            $location.path('/afterloginpath');
        }
      },
     function(errors){  //fail call back
      //  console.log(errors);
        $location.path('/login');
     });
    };
});

我的测试用例: -

'use strict';

describe('Controller: LoginCtrl', function () {

  // load the controller's module
  beforeEach(module('myApp'));

  var LoginCtrl, scope, location, login, loginReturn, session; …

我正在使用Karma和Jasmine对我的angularjs应用程序进行单元测试.我有一个指令(比如指令A)模板,其中另一个指令(比如指令B)被渲染,虽然它在应用程序中工作正常,但测试用例无法呈现指令B的模板.以下是我得到的错误: -

    Error: Unexpected request: GET views/partials/directiveb.html
Expected GET https://my-sandbox.app.com/123456

以下是指令A的代码: -

angular.module('myApp')
  .directive('directiveA', function (myservices, myOtherServices) {
    return {
        controller: function(){
        /* ... controller function ... */
        },
        templateUrl: '/views/partials/directivea.html',
        restrict: 'E',
        link: function postLink(scope, element, attrs) {
        /* ...link function... */
        }
    };
  });

指令A的模板: -

<div>
    <div class="col-md-12">
        <h4>We <strong>Need</strong></h4>
        <div directive-b some-attribute=="true"></div>
    </div>
    <div directive-b some-attribute=="false"></div>
</div>

指令A的测试案例: -

'use strict';

describe('Directive: directiveA', function () {

    // load the directive's module
    beforeEach(module('myApp'));
    beforeEach(module('template-module'));

    var element, appId, …

我有一个复杂的问题就是在手编辑一个数组.我有一个数组,其中一些元素是其他元素的子字符串.我想删除所有子字符串并仅保留超集/字符串.ie Array => ['1', '1 1', '1 1 1', '1 1 1 2', '1 2 3 1', '1 2', '2 3'] 操作后我应该有一个清理过的数组=>['1 1 1 2', '1 2 3 1']

是否有一种有效的算法来实现相同的目标？

我使用rails 2.3.11,ruby-1.9.2-p320.尝试运行脚本/服务器,但收到此错误: -

然后我在SO上提到几个答案并从终端运行以下命令: -

现在我收到错误: -

我正在使用 ruby​​ 1.9.3 使用“net/imap”库验证电子邮件凭据。如果我尝试在 Rails 控制台中使用以下代码，它会起作用：-

imap = Net::IMAP.new('imap.aol.com')
imap.authenticate('LOGIN', "username@aol.com".split("@").first, "password")

但是当我在 Rails 应用程序中使用它时，它给了我一个错误：-

Specified SASL mechanism not supported.

这种情况仅发生在 AOL 的情况下，雅虎在控制台和 Rails 应用程序中都可以工作。

有谁知道它可能是什么。

谢谢

我是 Mongodb 的新手，希望在 mongo 集合中实现对字段的搜索。

我的测试集合具有以下结构：-

{
  'key': <unique key>,
  'val_arr': [
               ['laptop', 'macbook pro', '16gb', 'i9', 'spacegrey'],
               ['cellphone', 'iPhone', '4gb', 't2', 'rose gold'],
               ['laptop', 'macbook air', '8gb', 'i5', 'black'],
               ['router', 'huawei', '10x10', 'white'],
               ['laptop', 'macbook', '8gb', 'i5', 'silve'],
}

我希望根据索引号和值找到它们，即找到其中任何一个val_arris中的第一个元素laptop和第三个元素的值 is的条目8gb。

我尝试查看 mongodb 中的复合索引，但它们的索引键限制为 32 个。任何在这个方向上的帮助表示赞赏。

我正在使用Rspec与Capybara运行使用VCR gem的集成测试来模拟存根api请求.我面临着各种奇怪的问题.测试第一次成功运行并创建yaml文件以保存请求及其响应.但是如果我在创建yaml文件后再次运行测试,那么它会遇到问题并显示以下问题: -
