微风元数据以xml格式显示 [英] Breeze Metadata appears in xml format

问题描述

微风无法创建实体。它查询元数据（在我的Controller类中），并返回带有200个代码的数据。然后，它查询数据，并返回200码。两组返回数据在表面上似乎都是json格式。

Breeze cannot create entities. It does the query for Metadata (which is in my Controller class) and it returns data with a 200 code. Then it queries the data, and returns with a 200 code. Both sets of return data appear to be json format on the surface.

再看一下Metadata，它似乎是json对xml元数据进行序列化。这对我来说并不正确-在微风站点上的实时示例中，似乎并没有这样做。

Looking further into the Metadata, it appears to be json serializing the xml metadata. This does not feel right to me - and on the live example on the breeze site, does not appear to be doing this.

任何人都对可能造成的原因有任何提示这个？元数据的开始方式如下：

Anyone have any tips on what might be causing this? Here is how the metadata starts:

"{\"?xml\":{\"version\":\"1.0\",\"encoding\":\"utf-8\"},\"schema\":{\"namespace\":

当服务返回数据时，我收到一个错误，其中包含完整的&正确的json响应。internalError报告无法获取未定义或空引用的属性'createCtor'

When the service returns data, I get an error, with the full & correct json response. The internalError reports "Unable to get property 'createCtor' of undefined or null reference"

当我调试了breeze.js：

It gets to this line in the mergeEntity function, when I debug breeze.js:

targetEntity = entityType._createEntityCore();

然后在ctr.prototype.getEntityCtor函数中-它无法使用此行从metadataStore的_typeRegistry属性获取实体的构造函数：

Then in the ctr.prototype.getEntityCtor function - it fails to get the entity's constructor from the metadataStore's _typeRegistry property using this line:

var aCtor = typeRegistry[this.name] || typeRegistry[this.shortName];

之后，将引发错误，最终导致executeQuery函数被捕获。

after that, the error is thrown and we end up in the catch of the executeQuery function.

推荐答案

我遇到的问题应该很明显。脚本更新后，我的捆绑配置不包括敲除脚本。如果遇到此问题，请确保已加载了绑定库（并且加载正确）。

The issue I was having should have been obvious. My bundling configuration was not including knockout scripts after the scripts have been updated. Be sure that you have a binding library loaded (and it's loading properly) if you experience this issue.
