问题描述

我开始与Angularjs +导轨后端,并试图从服务器获取用户数据 - 相当于为控制器/指数行动轨

我按照一些教程,发现这个code是最清楚的....

问题
1.如何正确链接角模块插入看法?
2.如何在这篇文章中使用预输入和样本数据来获取数据。

这里是的code

code是如下:

的意见

 < D​​IV NG-应用='用户'>
  < D​​IV CLASS ='集装箱液'NG控制器=UsersIndexCtrl>
    < pre>产品型号:{{结果| JSON}}< / pre>
    <输入类型=文本NG模型=结果预输入=的用户建议的建议($ viewValue)>
  < / DIV>
< / DIV>

控制器

 <脚本>  // ['ui.bootstrap','ngResource']) VAR应用= angular.module('用户',['ui.bootstrap','ngResource']);
 //工厂 - 资源的用户
 //相当于轨用户/指数
          app.factory(用户,函数($资源){
              返回$资源('/ users.json',{},{
                  指数:{方法:GET,IsArray的:真正}
              });
          }); //工厂 - 用户资源
 //相当于用户显示,更新
          app.factory(用户,函数($资源){
              返回$资源('/用户/:user_id.json',{},{
                  显示:{方法:GET},
                  更新:{方法:把'}
              });
          });//控制器 - 用户/指数
//相当于导轨控制器轨/索引  VAR UsersIndexCtrl =功能($范围,用户){      $ scope.users =用户;
  };< / SCRIPT>

和我在这里栈,我得到这个错误:

 错误:未知提供商:usersProvider<  - 用户

此code的目标是使用typehead并提供数据给用户。

我的'/users.json'网址如下:

  [{FULL_NAME:利亚卡特赖特,ID:1,图片网址:无icon.jpg},{FULL_NAME:希尔顿特纳,标识:2,图片网址:无icon.jpg},{FULL_NAME:奥布里巴罗斯,ID:3,图片网址:无icon.jpg}, {FULL_NAME:唐尼克里斯,ID:4,图片网址:无icon.jpg},{FULL_NAME:Eryn拉特,ID:5,图片网址:无icon.jpg},{FULL_NAME:恺迪来费伊,ID:6,图片网址:无icon.jpg},{FULL_NAME:阿莉特龙普,身份证 7,图片网址:无icon.jpg},{FULL_NAME:波多黎各克莱恩,ID:8,图片网址:无icon.jpg},{FULL_NAME: 古德龙敢为天下先,ID:9,图片网址:无icon.jpg},{FULL_NAME:内森Langworth,ID:10,图片网址:无icon.jpg },{FULL_NAME:迪安娜斯特罗曼,ID:11,图片网址:无icon.jpg},{FULL_NAME:仙妮亚斯特罗曼,ID:12,IMAGE_URL :无icon.jpg},{FULL_NAME:卢佩哈维,ID:13,图片网址:无icon.jpg},{FULL_NAME:阿姆斯特朗康斯 ID:14日,图片网址:无icon.jpg},{FULL_NAME:里根特伦布莱,ID:15日,图片网址:无icon.jpg},{ FULL_NAME:默里赛普斯,ID:16,图片网址:无icon.jpg},{FULL_NAME:Dandre克洛科,ID:17日,图片网址:NO- icon.jpg},{FULL_NAME:Haylee莫纳汉,ID:18日,图片网址:无icon.jpg},{FULL_NAME:佛罗伦萨Harber,ID:19 图片网址:无icon.jpg},{FULL_NAME:诺韦尔托·霍普,ID:20,图片网址:无icon.jpg}]


解决方案

您必须注用户不是用户,它是区分大小写的。


旁注:

没有必要建立两个模型,替换:

  app.factory('用户',函数($资源){
  返回$资源('/ users.json',{},{
    指数:{方法:GET,IsArray的:真正}
  });
});app.factory(用户,函数($资源){
  返回$资源('/用户/:user_id.json',{},{
    显示:{方法:GET},
    更新:{方法:把'}
  });
});

  app.factory(用户,函数($资源){
  返回$资源(用户/:ID,{ID:'@id'},{
    指数:{方法:GET,IsArray的:真实,responseTyp的:JSON},
    显示:{方法:GET,responseTyp的:JSON},
    更新:{方法:把',responseTyp的:'JSON'}
  });
})

其他的东西,在你的控制器,做的:

  VAR UsersIndexCtrl =功能($范围,用户){
  $ scope.users = User.index();
};

最后一件事,可以考虑使用:角Rails的资源

I am starting with Angularjs + rails backend and trying to fetch users data from the server - equivalent to to controller/index action in rails.

I have followed several tutorials and found this code as the most clear one....

questions 1. How to properly link angular module into views ? 2. How to fetch data using typeahead and sample data in this post.

here is plunker version of the code

Code is as follows:

views

<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>

controller

<script>

  // ['ui.bootstrap', 'ngResource'])

 var app = angular.module('users', ['ui.bootstrap', 'ngResource']);


 // factory - resources users
 // equivalent to rails users/index
          app.factory('Users', function($resource) {
              return $resource('/users.json', {}, {
                  index: { method: 'GET', isArray: true}
              });
          });

 // factory - user resource
 // equivalent to users show, update
          app.factory('User', function($resource) {
              return $resource('/users/:user_id.json', {}, {
                  show: { method: 'GET' },
                  update: { method: 'PUT' }
              });
          });

// controller - users/ index
// equivalent to rails controller rails/index

  var UsersIndexCtrl = function($scope, users) {

      $scope.users = users;
  };

</script>

and I am stack here, as I am getting this error:

Error: Unknown provider: usersProvider <- users

The goal of this code is to use typehead and provide data to the user.

My '/users.json' url is as follows:

[{"full_name":"Lia Cartwright","id":1,"image_url":"no-icon.jpg"},{"full_name":"Hilton Turner","id":2,"image_url":"no-icon.jpg"},{"full_name":"Aubrey Barrows","id":3,"image_url":"no-icon.jpg"},{"full_name":"Donnie Kris","id":4,"image_url":"no-icon.jpg"},{"full_name":"Eryn Rath","id":5,"image_url":"no-icon.jpg"},{"full_name":"Caden Fay","id":6,"image_url":"no-icon.jpg"},{"full_name":"Arlie Tromp","id":7,"image_url":"no-icon.jpg"},{"full_name":"Rico Klein","id":8,"image_url":"no-icon.jpg"},{"full_name":"Gudrun Dare","id":9,"image_url":"no-icon.jpg"},{"full_name":"Nathan Langworth","id":10,"image_url":"no-icon.jpg"},{"full_name":"Deanna Stroman","id":11,"image_url":"no-icon.jpg"},{"full_name":"Shania Stroman","id":12,"image_url":"no-icon.jpg"},{"full_name":"Lupe Harvey","id":13,"image_url":"no-icon.jpg"},{"full_name":"Constance Armstrong","id":14,"image_url":"no-icon.jpg"},{"full_name":"Reagan Tremblay","id":15,"image_url":"no-icon.jpg"},{"full_name":"Murray Sipes","id":16,"image_url":"no-icon.jpg"},{"full_name":"Dandre Klocko","id":17,"image_url":"no-icon.jpg"},{"full_name":"Haylee Monahan","id":18,"image_url":"no-icon.jpg"},{"full_name":"Florence Harber","id":19,"image_url":"no-icon.jpg"},{"full_name":"Norberto Hoppe","id":20,"image_url":"no-icon.jpg"}] 

解决方案

You must inject Users not users, it's case sensitive.


Side notes:

No need to create two models, replace:

app.factory('Users', function($resource) {
  return $resource('/users.json', {}, {
    index: { method: 'GET', isArray: true}
  });
});

app.factory('User', function($resource) {
  return $resource('/users/:user_id.json', {}, {
    show: { method: 'GET' },
    update: { method: 'PUT' }
  });
});

with:

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' }
  });
})

Other thing, in your controller, do:

var UsersIndexCtrl = function($scope, User) {
  $scope.users = User.index();
};

Last thing, consider using: Angular Rails resource
