使用重复指令从API输出葡萄酒记录。我有一个工厂函数来提供葡萄酒API,然后在我的控制器中访问它。
app.factory("Wine", function ($http){
var factory = {};
//getWines
factory.getWines = function(){
return $http.get("http://www.greatwines.9000.com")
}
}
控制器:
app.controller("winesCtrl", function($scope, $http, Wine){
Wine.getWines()
.success(function(wines){
$scope.wines = wines;
})
.error(function(){
alert("Error!");
});
});
VIEW:
<h2>Wine list</h2>
<div class="row margin-top-20 wine-container" ng-repeat="wine in wines">
<div class="col-sm-3">
<img src="{{wine.picture}}" class="img-responsive" />
</div>
<div class="col-sm-9">
<div class="margin-top-20">
<span class="bold">Name: </span><span>{{wine.name}}</span>
</div>
<div>
<span class="bold">Year: </span><span>{{wine.year}}</span>
</div>
<div>
<span class="bold">Grapes: </span><span>{{wine.grapes}}</span>
</div>
<div>
<span class="bold">Country: </span><span>{{wine.country}}</span>
</div>
<div>
<span class="bold">Region: </span><span>{{wine.region}}</span>
</div>
<div>
<span class="bold">Price: </span><span>{{wine.price}}</span>
</div>
<div>
<span class="bold">{{wine.description}}</span>
</div>
<div class="margin-top-20">
<a href="#/wines/{{wine.id}}" class="btn btn-default">Edit Wine</a>
</div>
</div>
</div>
我点击了这个错误,在典型的“含糊不清”的angularjs风格中,我得到了以下内容:
Duplicates in a repeater are not allowed. Use 'track by' expression to specify unique keys. Repeater: wine in wines, Duplicate key: string:e, Duplicate value: e
这是什么意思?“wine”和“wines”不一样,为什么它认为它们是重复的?
