</html>模型，并且我的comment属性在模型上有AuthorID数据注释。
我在保存之前在控制器中设置了[Required]。但是，ModelState总是回来说明需要AuthorID字段。
如何在模型中保留我的验证并在此方案中正确验证？
AuthorID答案 0 :(得分：1)
- 您可以使用TryValidateModel（），但首先需要清除模型状态，然后再次重新验证模型 ASP.NET MVC TryValidateModel() Issues when Model is Modified
public async Task<IActionResult> PostComment([FromBody] Comment comment)
{
comment.AuthorID = Utilities.GetUserId(this.User);
comment.CreatedAt = DateTime.Now;
ModelState.Clear();
if (!TryValidateModel(comment)) // the same as !ModelState.IsValid
{
//Failure
}
//Success
}
答案 1 :(得分：0)
您可以使用
删除ModelState验证ModelState.Remove("AuthorID")
答案 2 :(得分：0)
创建一个ViewModel并将其传递给Controller Post
public async Task<IActionResult> PostComment([FromBody] CommentModel comment)
{}
关于你需要AuthorID的其他逻辑，为此创建另一个ViewModel， 为什么你决定只依赖一种型号的东西!!
