微風與角落entityManagerfactory

我想創建與Angular Breeze的entityManagerFactory。我使用HotTowel開始了我的項目，但是當我嘗試獲取新的工廠集時，我收到了breeze.debug.js模塊發生的錯誤。它屬於這種情況，因爲它似乎預計該屬性的類型與該屬性的名稱相匹配。我不確定我是否理解這裏發生的事情。任何人都可以將我指向正確的方向嗎？在datacontext.js 調用代碼：微風與角落entityManagerfactory

 function getProjects() { 
     return breeze.EntityQuery.from('Projects') 
      .using(manager) 
      .execute() 
      .then(success) 
      .catch(fail) 
    };

廠服務：在breeze.debug.js

(function() { 
'use strict'; 

var serviceId = 'entityManagerFactory'; 
angular.module('app').factory(serviceId, ['breeze', emFactory]); 

function emFactory(breeze) { 
    // Convert server-side PascalCase to client-side camelCase property names 
    breeze.NamingConvention.camelCase.setAsDefault(); 
    // Do not validate when we attach a newly created entity to an EntityManager. 
    // We could also set this per entityManager 
    new breeze.ValidationOptions({ validateOnAttach: false }).setAsDefault(); 

    var serviceRoot = "http://localhost:51362/"; 
    var serviceName = serviceRoot + 'breeze/ProjectTracking'; 

    var manager = new breeze.EntityManager(serviceName); 
    var factory = { 
     newManager: manager, 
     serviceName: serviceName 
    }; 

    return factory;   
} 

})();

違規代碼：

function processUsing(eq, map, value, propertyName) { 
var typeName = value._$typeName || (value.parentEnum && value.parentEnum.name); 
var key = typeName && typeName.substr(0, 1).toLowerCase() + typeName.substr(1); 
if (propertyName && key != propertyName) { 
    throw new Error("Invalid value for property: " + propertyName); 
}

由錯誤判斷，它看起來像'.using（manager）'中的「manager」實際上是工廠而不是EntityManager。 –

內，您的DataContext的服務，你可以添加以下內容：

var _primePromise; 

function prime() { 
    if (_primePromise) return _primePromise; 
    _primePromise = manager.fetchMetadata() 
     .then(extendMetadataStore) 
     .catch(function(err) { 
     _primePromise = null; 
     throw err; 
     }); 
    return _primePromise; 
} 

function extendMetadataStore() { 
    var store = manager.metadataStore; 
    var entityTypes = store.getEntityTypes(); 
    entityTypes.forEach(function(entityType) { 
     if (entityType instanceof EntityType) { 
     var resourceName = entityType.shortName; 
     store.setEntityTypeForResourceName(resourceName, entityType); 
     } 
    }); 
}

然後你只需要確保你調用datacontext.prime（）您撥打電話到getProjects前（）。我在解析路由之前調用datacontext.prime（）。
