Ruby on rails 如何使用rails服务器在Angular中获取索引数据

我从Angularjs+rails后端开始，尝试从服务器获取用户数据——相当于rails中的

controller/index

action

我遵循了几个教程，发现这段代码是最清晰的

问题 1.如何正确地将角度模块链接到视图中？ 2.如何在本文中使用typeahead和示例数据获取数据

这是

代码如下：

视图

<div ng-app='users'>
  <div class='container-fluid' ng-controller="UsersIndexCtrl">
    <pre>Model: {{result | json}}</pre>
    <input type="text" ng-model="result" typeahead="suggestion for suggestion in users($viewValue)">
  </div>
</div>

您必须注入

用户

而不是

用户

，它区分大小写

旁注：

无需创建两个模型，请替换：

app.factory('User', function($resource) {
  return $resource("users/:id", { id: '@id' }, {
    index:   { method: 'GET', isArray: true, responseType: 'json' },
    show:    { method: 'GET', responseType: 'json' },
    update:  { method: 'PUT', responseType: 'json' }
  });
})

与：

在控制器中，执行以下操作：

最后一件事，考虑使用：

在您的Spulk版本的代码中，您没有angal.js文件加载到您的模板中。谢谢您的评论，它现在更新了…感谢您的评论-更新..现在我得到：

TypeError:无法读取未定义的属性“length”

，因为服务异步返回结果，您无法找到它的属性，如length等。感谢您的阅读，无论如何我还有一些问题，但是你的建议给了我很多帮助，也给了我方向…因为提供的价值，我接受了答案。按照你的建议，我得到了另一个错误：）

未捕获的错误：无模块：用户

…任何澄清这一点的更改请…？我需要更多的上下文，请你将此作为另一个问题详细发布？
