Question

我是EntityFramework和ASP.Net的新手

我正在使用EF在Asp.net MVC5中创建一个身份验证系统，我的数据库中有以下字段

Id | Name | Contact | Url | Username | Password

我的模型Clients.cs的类Clients需要存储在数据库中：

public class Clients
{
    public int Id { get; set; }

    [Required]
    public string Name { get; set; }

    public long? Contact { get; set; }

    [Required]
    [Display(Name = "Site Url")]
    public string Url { get; set; }

    [Required]
    public string Username { get; set; }

    [Required]
    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    public string Password { get; set; }

    [Required]
    [Compare("Password", ErrorMessage = "Password Mismatched. Re-enter your password")]
    [DataType(DataType.Password)]
    [Display(Name = "Confirm Password")]
    public string ConfirmPassword { get; set; }

}

我尝试存储凭证，如下所示：

//Controller::

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Index(Clients clients)
    {
        if (ModelState.IsValid)
        {
            Clients client = new Clients();
            client.Name = clients.Name;
            client.Password = clients.Password;
            client.Url = clients.Url;
            client.Username = clients.Username;
            client.Contact = clients.Contact;

            dbContext.Clients.Add(client);
            dbContext.SaveChanges();
            return RedirectToAction("api/products");
        }
        return View();
    }

显示错误：

Server Error in '/ProductsApp' Application.

Validation failed for one or more entities. See 'EntityValidationErrors' property for more details.

Line 35:                 return RedirectToAction("Index");
Line 36:             }

如何将所有字段存储在除ConfirmPassword字段之外的数据库中。

Answer 1

使用NotMappedAttribute：

[NotMapped]
public string MyProperty { get; set; }

您的财产将成为：

[Required]
[Compare("Password", ErrorMessage = "Password Mismatched. Re-enter your password")]
[DataType(DataType.Password)]
[Display(Name = "Confirm Password")]
[NotMapped]
public string ConfirmPassword { get; set; }

我在Marthijn

的帮助下解决了问题

我将客户端确认密码更改为：

[Compare("Password", ErrorMessage = "Password Mismatched. Re-enter your password")]
[DataType(DataType.Password)]
[Display(Name = "Confirm Password")]
[NotMapped]
public string ConfirmPassword { get; set; }

和Controller的代码为：

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Index(Clients clients)
{
    if (ModelState.IsValid)
    {
        dbContext.Clients.Add(client);
        dbContext.SaveChanges();
        return RedirectToAction("Index");
    }
    return View();
}

它有效.... 感谢Marthijn

仅使用EF插入ASP.NET中数据库字段中的值
