我无法通过breeze.savechanges（）来检测实体更改。我想要的只是简单地创建新的 order-＆gt; orderdetails 相关实体，修改它然后保存更改但是非常失败，所以我在一个名为 data 的工厂中拥有breeze管理器是我的控制者
angular.module("InventoryApp")
.controller("PurchasesCtrl", function ($scope, data, $log) {
var setFields=function(){
var product = data.createEntity("Product");
var purchaseOrder=data.createEntity("PurchaseOrder");
$scope.purchaseOrder = purchaseOrder;
$scope.product = product; //binding entities to view for edits
};
$scope.save = function(product, purchaseOrder) { //i am calling this from view
purchaseOrder.Time = new Date();
product.PurchaseOrders.push(purchaseOrder); //creating a relation
data.saveChanges(); //breeze refuses to save claim it have no changes
setFields(); //binding new fresh enties
};
setFields(); //binding new entities to view for edits
});
我已经尝试了data.saveChanges([product,purchaseOrder])但是我在产品和购买之间的关系有些丢失，服务器在purchaseOrder中返回验证错误，它必须有一个有效的产品（它不会与我发送的新产品相关联？ ）
data.saveChanges([product])只会保存产品并忽略PurchaseOrder，尽管product.PurchaseOrders.push(purchaseOrder);正在工作。
使用purchaseOrder.Product=product;代替product.PurchaseOrders.push(purchaseOrder);来创建关系提供相同的故事。
在使用开发工具进行调试时，关系看起来完美脱机的方式，但是当我通过强制发送实体时，breeze管理器hasChanges frag不会变为true，服务器会出现错误。
我怀疑元数据是问题，因为服务器生成将其保存在Metadata.js上并在app.run期间提供给应用程序，但这里是元数据。
