Sql 在ASP.NET MVC中更新表问题

我有一个ASP.NET MVC模型类，如下所示：

using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;

public partial class Customer
{
    [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
    public Customer()
    {
        this.Rates_Comments = new HashSet<Rates_Comments>();
    }

    [Required]
    public double ID { get; set; }
    [Required]
    public string Marital_Status { get; set; }
    [Required]
    public string Gender { get; set; }
    [Required]
    [Range(5000,500000)]
    public double Income { get; set; }
    [Required]
    public double Children { get; set; }
    [Required]
    public string Education { get; set; }
    [Required]
    public string Occupation { get; set; }
    [Required]
    public string Home_Owner { get; set; }

我的问题是，由于

[必需]

数据注释，我无法更新表中的一个单元格。例如，用户必须访问其帐户才能编辑它（如果需要），因此他只能编辑一个字段，而不是全部字段

而由于注册问题，所有备案都是必需的，那么如何克服这个问题呢

<h2>Update My Account:</h2>

@using (Html.BeginForm())
