我正在尝试使用以下操作结果使用 EF5 更新条目:
[HttpPost]
public ActionResult Edit(int id, IEnumerable<HttpPostedFileBase> files)
{
if (ModelState.IsValid)
{
Reference reference = db.References.Single(x => x.Id == id);
db.Entry(reference).State = EntityState.Modified;
db.SaveChanges();
//Other stuff regarding files/images
return RedirectToAction("Index");
}
return View();
}
没发生什么事。当我调试它时,它会通过代码,因为一切都很好。但是数据库中没有任何更新。
如果需要,这是模型:
public class Reference
{
public int Id { get; set; }
public string Headline { get; set; }
public string Text { get; set; }
public DateTime Date { get; set; }
public IEnumerable<HttpPostedFileBase> ImageUploadMain { get; set; }
public String MainFileName { get; set; }
public IEnumerable<HttpPostedFileBase> ImageUpload { get; set; }
public virtual ICollection<Image> Files { get; set; }
public virtual ICollection<RefProperties> Properties { get; set; }
public int CategoryId { get; set; }
public virtual Category Category { get; set; }
}
public class Image
{
public int Id { get; set; }
public string FileName { get; set; }
public virtual Reference Reference { get; set; }
}
public class RefProperties
{
public int Id { get; set; }
public string Key { get; set; }
public string Value { get; set; }
}
public class Category
{
public int CategoryId { get; set; }
public string Name { get; set; }
public virtual ICollection<Reference> References { get; set; }
}
不仅相关条目没有更新,像“标题”这样的主要属性也不能更新。我究竟做错了什么?顺便说一句,创建/删除工作正常。
