我得到这个方法的DomainService我最SL的ViewModel使用Invoke属性调用:通过利雅的DomainService调用返回相关成员方法
[Invoke]
public ServiceModel.Recipy GetRecipyById(int recipyId)
{
return new Recipy
{
RecipyId = 1,
Name = "test",
Description = "desc",
Author = new Author
{
AuthorId = 1,
Name = "Johan"
}
};
}
在我的视图模型的代码如下所示:
public RecipyViewModel()
{
context.GetRecipyById(1, RecipyLoadedCallback, null);
}
private void RecipyLoadedCallback(InvokeOperation<Recipy> obj)
{
_name = obj.Value.Name;
_description = obj.Value.Description;
_authorName = obj.Value.Author.Name;
}
的Recipy和作者POCO/ServiceModel类:
public class Recipy
{
[Key]
public int RecipyId { get; set; }
public string Name { get; set; }
public string Description { get; set; }
[Association("Author", "RecipyId", "AuthorId")]
[Include]
public Author Author { get; set; }
}
public class Author
{
[Key]
public int AuthorId { get; set; }
public string Name { get; set; }
}
现在,代码工作正常,excep t关联的作者没有被转移到客户端/视图模型,Recipy的Author属性为空。我认为使用[Associate]和[Include]属性会有诀窍吗?
感谢您的帮助,我努力地神交的DomainService/RIA的东西,我很接近放弃走“正常” WCF/REST,而不是:)
