Breeze mit Angular entityManagerfactory

Question

Ich versuche, die EntityManagerFactory für Breeze mit Angular zu erstellen. Ich habe HotTowel verwendet, um mit meinem Projekt zu beginnen, aber wenn ich versuche, die neue Werkseinstellung zu bekommen, erhalte ich eine Fehlermeldung vom Modul breeze.debug.js. Es fällt dort hin, weil es so aussieht, als ob der Typ der Eigenschaft mit dem Namen der Eigenschaft übereinstimmt. Ich bin mir nicht sicher, ob ich verstehe, was hier vor sich geht. Kann mir jemand in die richtige Richtung zeigen? Telefonvorwahl in datacontext.js:

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

Werksservice:

(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;   
} 

})(); 

fehlerhaften Code in breeze.debug.js:

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); 
}

Answer 1

In Ihrem Datacontext Service Sie folgende hinzufügen könnte:

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); 
     } 
    }); 
} 

Dann einfach Sie sicherstellen, dass Sie die datacontext.prime() aufrufen, bevor Sie Aufruf getProjects machen(). Ich rufe die datacontext.prime() vor dem Auflösen einer Route.
