我正在尝试通过运行典型的待办教程来学习Angular和Firebase,但我正在修改应用程序。而不是待办事项列表,我实际上是创建'用户'。
Firebase已正确设置,从Firebase中提取对象数据也是如此,我可以通过ng-repeat看到所有内容按预期填充。
但我正在尝试使用.push()方法“添加新成员”,我收到错误。请看一下:
以下是我上传到Firebase(只有一个用户)
的JSON数据示例{
"members": {
"-JWT5y43YFy1mGirVVS2": {
"date": 1410328158691,
"firstname": "Michael",
"lastname": "Jordan",
"project": "sample project description",
"image": "http://telehealth.org/wp-content/images/user-placeholder.jpg",
"upcoming": "PTO on Thursday",
"status": {
"color": "red",
"contact": {
"email": "test@email.com",
"yahoo": "yahooIM"
},
"projects": {
"projectone": "project one",
"projecttwo": "project two",
"projectthree": "project three"
}
}
}
}
}
这是我的.html代码
<h1 id="teamTitle">Team Members</h1>
<div class="addMember">
<p>add member</p>
<form class="formmember"
name="memberform"
ng-submit="addMember()"
novalidate>
<div class="inputwrapper">
<input type="text" name="firstname" placeholder"First Name" ng-required="true">
<button type="submit" class="btn"
ng-disabled="memberform.$invalid">Add</button>
</div>
</form>
</div>
<ul class="cbp-rfgrid" ng-repeat="member in members">
<li class="{{member.status.color}}">
<img src="{{member.image}}">
<div>
<h3>{{member.firstname}}</h3>
<button>View</button>
</div>
</li>
</ul>
这是我的Controller.js
myApp.controller('MembersController', function($scope, $firebase){
var ref = new Firebase('https://scrumcheck.firebaseio.com/members');
var members = $firebase(ref);
$scope.members = members.$asObject();
$scope.addMember = function(){
members.$push({
firstname: $scope.firstname,
date: Firebase.ServerValue.TIMESTAMP
});
}
});
控制台日志显示以下错误:
Error: Firebase.set failed: First argument contains undefined in property 'firstname'
我希望通过向成员推送一个只有firstname键的对象,它允许我这样做。我只允许push()一个整个对象,其中包含所有键值吗?
谢谢!

检查您的$ scope.firstname模型,问题出在哪里。确保它不是空值并且正确定义。
