.net WebApi OData +微风=> [Q]未处理的拒绝原因(应为空) [英] .net WebApi OData + breeze => [Q] Unhandled rejection reasons (should be empty)

问题描述

我有一个带有OData EntitySetController的.net 4.5 Web Api

I have a .net 4.5 Web Api with OData EntitySetController

在客户端，我加载了以下js文件

In client side I got the following js files loaded

jquery.min.js
q.min.js
datajs-1.1.1.min.js
breeze.debug.js
toastr.min.js
angular.js

当我调用以下javascript

when I call the following javascript

breeze.config.initializeAdapterInstance("dataService", "OData");
var manager = new breeze.EntityManager(serviceName);

var query = breeze.EntityQuery.from("Customers");

return manager.executeQuery(query).then(success).fail(fail);

function success(data) {
  $log.info("Retrieved " + data.results.length);
  return data.results;
}

function fail(data) {
  $log.info("error " + data);
}

我在chrome网络标签中看到以下内容，其中显示了元数据，而json数据又很好地返回了...

I see the following in my chrome network tab showing metadata and the json data are coming back nicely...

Request URL:http://localhost:49971/odata/$metadata
Status Code:200 OK, 1.8KB

Request URL:http://localhost:49971/odata/Customers
Status Code:200 OK, 3.3KB

但是成功回调永远不会触发，失败回调将被执行.有人可以帮忙吗?我所看到的就是

BUT the success callback never fires, the fail callback gets executed. Can any one help please? All I see is

XHR finished loading: "http://localhost:49971/odata/$metadata". datajs-1.1.1.min.js:14
XHR finished loading: "http://localhost:49971/odata/Customers". datajs-1.1.1.min.js:14
[Q] Unhandled rejection reasons (should be empty): 
[Error]
length: 0
__proto__: Array[0]
 q.js:1010
error Error: OK 

然后我需要将它们数据绑定到ng-grid，ng-form，最后将它们发送回数据库到服务器端...

I then need to databind these to a ng-grid, ng-form and then finally send them back to database to serverside...

更多代码和屏幕截图

breeze.EntityQuery
  .from("AddressTypes")
  .using(new breeze.EntityManager(serviceName))
  .execute()
  .then(function(data) {
    console.log(data); // never gets here very wierd
  }).fail(function(e) {
    console.log(e); // shows an error object with the AddressType Array
  });

我在失败回调中看到AddresTypes数组...

I see the AddresTypes array in fail callback...

更新:我已经在后端临时切换到BreezeContoller而不是EntitySetController，并注释掉了breeze.config.initializeAdapterInstance("dataService", "OData");，我在successCb中得到了我的数组.所以我想我可以推断我在DataJS方面遇到了麻烦.真的很想坚持使用EntitySetController ...

update: I have temporarily switched to a BreezeContoller instead of EntitySetController in the backend, and commented out breeze.config.initializeAdapterInstance("dataService", "OData"); And I get my array in successCb. So I think I can infer I am running into trouble with DataJS. Really would like to stick with EntitySetController though...

推荐答案

我遇到了同样的问题. 事实证明，回到datajs 1.0.3似乎可行. 但是，这样做导致$ expand无法工作(服务器可以工作，但是微风无法处理它的导航属性->不管其多重性如何.)

I had the same problem. As it turned out, going back to datajs 1.0.3 seemed to work. However, doing that resulted $expand to not work (the server works, but breeze doesn't handle it the navigation properties -> regardless its multiplicity).

我必须说，我想寻找一个与 STABLE breezejs相当的产品.

I must say, I am terrible looking for a STABLE breezejs equivalent.
