更新应该看起来像(扩展 Dan Beaulieu 的回答) :
Update should look like (expanding on Dan Beaulieu's answer) :
[HttpPost]
[ValidateAntiForgeryToken]
[ValidateInput(false)]
public ActionResult Edit([Bind(Include = "Id,Title,IntroText,Body,Modified,Author")] Post post)
{
using (UnitOfWork uwork = new UnitOfWork())
{
post.Modified = DateTime.Now;
uwork.PostRepository.Update(post);
uwork.Commit();
return RedirectToAction("Index");
}
}
RepositoryPattern 如下所示:
public class BlogEngineRepository<T> : IRepository<T> where T : class
{
public BlogEngineRepository(DbContext dataContext)
{
DbSet = dataContext.Set<T>();
Context = dataContext;
}
public T Update(T entity)
{
DbSet.Attach(entity);
var entry = Context.Entry(entity);
entry.State = System.Data.EntityState.Modified;
}
}
