Breeze.js - 收到錯誤嘗試使用「任何」運營商 - 錯誤：無法獲得屬性「isAnonymous」的值：對象爲空或未定義

Question

我試圖用「任何」運營商在清風查詢很多表和我得到以下錯誤 - TypeError：無法獲取屬性的值'isAnonymous'：對象爲空或未定義

唯一的stackoverflow問題，我可以找到似乎相關的是這一個，但沒有解決isAnonymous問題，因爲海報沒有提供更多的代碼：

breeze projection : error selecting non scalar navigation properties

我一個米用微風1.4.11與 實體框架5

我試圖運行查詢是

var getEntities = function (entitiesObservable) { 
    var whereClause = ""; 

    whereClause = Predicate.create("t_entity_nm", "any", "frst_nm", "startsWith", "Frank"); 

    var query = EntityQuery.from("Entities") 
          .where(whereClause) 
          .expand("t_entity_nm"); 

    $('#loading-indicator').show(); 
    return manager.executeQuery(query) 
        .then(querySucceeded) 
        .fail(queryFailed); 

    function querySucceeded(data) { 
     $('#loading-indicator').hide(); 
     if (entitiesObservable) { 
      entitiesObservable(data.results); 
     } 
     log("Retrieved [Entities] from remote data source", data, true); 
    } 
}; 

t_entity加入到t_entity_nm上entity_sys_key_id ...他們的意見......這裏的視圖定義

微風控制器看起來是這樣的：

namespace MarketingPromotions.Controllers 
{ 
    [BreezeController(MaxAnyAllExpressionDepth = 2)] 
    public class BreezeController : ApiController 
    { 

    readonly EFContextProvider<OASIS_DEVEntities> _contextProvider = 
      new EFContextProvider<OASIS_DEVEntities>(); 

     [HttpGet] 
     public string Metadata() 
     { 
      return _contextProvider.Metadata(); 
     } 
     #endregion 

     [HttpGet] 
     public IQueryable<t_entity> Entities() 
     { 
      return _contextProvider.Context.t_entity; 
     } 

     [HttpGet] 
     public IQueryable<t_entity_nm> EntityNames() 
     { 
      return _contextProvider.Context.t_entity_nm; 
     } 
} 

的代碼在那裏斷裂是在上線breeze.debug.js - >

if (entityType.isAnonymous) return; 

其中「這個」是在從breeze.debug.js下面的代碼段的frst_nm字段：

proto._validate = function(entityType) { 
     // will throw if not found; 
     if (this.isValidated) return;    
     this.isValidated = true; 
     if (this.propertyPath) { 
      if (entityType.isAnonymous) return; 
      var prop = entityType.getProperty(this.propertyPath, true); 
      if (!prop) { 
       var msg = __formatString("Unable to resolve propertyPath. EntityType: '%1' PropertyPath: '%2'", entityType.name, this.propertyPath); 
       throw new Error(msg); 
      } 
      if (prop.isDataProperty) { 
       this.dataType = prop.dataType; 
      } else { 
       this.dataType = prop.entityType; 
      } 
     } else if (this.fnNodes) { 
      this.fnNodes.forEach(function(node) { 
       node._validate(entityType); 
      }); 
     } 
    };

這看起來像資源名稱問題。我的猜測是，你還沒有建立資源名稱/實體類型映射。

在這些鏈接看看：
