我正在執行與Breezesharp應用程序。在EntityManager中插入實體時遇到問題。錯誤是:BreezeSharp附加屬性鍵未找到
有沒有上的EntityType尚未定義KeyProperties:「TransportReceipt:#Business.DomainModels」
我已經遇到這個錯誤我的第一個實體類型的「客戶」,實行不匹配方法建議here。在那種情況下,我成功地對我的WebApi進行了get操作。但是現在我在我的應用程序中創建了TransportReceipt實體。
映射錯配修復
public static class ExtendMap
{
private static bool? executed;
public static void Execute(MetadataStore metadataStore) {
if (ExtendMap.executed == true)
{
return;
}
var customerBuilder = new EntityTypeBuilder<Customer>(metadataStore);
customerBuilder.DataProperty(t => t.id).IsPartOfKey().IsAutoIncrementing();
var transportReceiptBuilder = new EntityTypeBuilder<TransportReceipt>(metadataStore);
transportReceiptBuilder.DataProperty(t => t.id).IsPartOfKey().IsAutoIncrementing();
var transportReceiptAttachmentBuilder = new EntityTypeBuilder<TransportReceiptAttachment>(metadataStore);
transportReceiptAttachmentBuilder.DataProperty(t => t.id).IsPartOfKey().IsAutoIncrementing();
var uploadedFileBuilder = new EntityTypeBuilder<UploadedFile>(metadataStore);
uploadedFileBuilder.DataProperty(t => t.id).IsPartOfKey().IsAutoIncrementing();
ExtendMap.executed = true;
}
}
我的基本DataService的核心代碼
public abstract class SimpleBaseDataService
{
public static string Metadata { get; protected set; }
public static MetadataStore MetadataStore { get; protected set; }
public string EntityName { get; protected set; }
public string EntityResourceName { get; protected set; }
public EntityManager EntityManager { get; set; }
public string DefaultTargetMethod { get; protected set; }
static SimpleBaseDataService()
{
try
{
var metadata = GetMetadata();
metadata.Wait();
Metadata = metadata.Result;
MetadataStore = BuildMetadataStore();
}
catch (Exception ex)
{
var b = 0;
}
}
public SimpleBaseDataService(Type entityType, string resourceName, string targetMethod = null)
{
var modelType = typeof(Customer);
Configuration.Instance.ProbeAssemblies(ConstantsFactory.BusinessAssembly);
try
{
this.EntityName = entityType.FullName;
this.EntityResourceName = resourceName;
this.DefaultTargetMethod = (string.IsNullOrWhiteSpace(targetMethod) ? "GetAllMobile" : targetMethod);
var dataService = new DataService($"{ConstantsFactory.Get.BreezeHostUrl}{this.EntityResourceName}", new CustomHttpClient());
dataService.HasServerMetadata = false;
this.EntityManager = new EntityManager(dataService, SimpleBaseDataService.MetadataStore);
this.EntityManager.MetadataStore.AllowedMetadataMismatchTypes = MetadataMismatchTypes.AllAllowable;
// Attach an anonymous handler to the MetadataMismatch event
this.EntityManager.MetadataStore.MetadataMismatch += (s, e) =>
{
// Log the mismatch
var message = string.Format("{0} : Type = {1}, Property = {2}, Allow = {3}",
e.MetadataMismatchType, e.StructuralTypeName, e.PropertyName, e.Allow);
// Disallow missing navigation properties on the TodoItem entity type
if (e.MetadataMismatchType == MetadataMismatchTypes.MissingCLRNavigationProperty &&
e.StructuralTypeName.StartsWith("TodoItem"))
{
e.Allow = false;
}
};
}
catch (Exception ex)
{
var b = 0;
}
}
}
這是誰我想添加新的實體
//DataService snippet
public void AttachEntity(T entity)
{
this.EntityManager.AttachEntity(entity, EntityState.Added);
}
//Business
this.TransportReceipt = new TransportReceipt { id = Guid.NewGuid(), date = DateTime.Now, customerId = Customer.id/*, customer = this.Customer*/ };
this.Attachments = new List<TransportReceiptAttachment>();
this.TransportReceipt.attachments = this.Attachments;
TransportReceiptDataService.AttachEntity(this.TransportReceipt);
當我嘗試添加將實體添加到EntityManager中,我可以看到所有實體類的自定義映射。
所以我的問題是我做錯了什麼。
問題是因爲我創建的實體類不使用Breezesharp模式。 GetValue,SetValue。 –
