Hello, all right? I need some help from you, I already searched here on the forum but I was not successful with the results. I have a small application where I control Digital Certificates, my Certificate model is simple as below:

Entity Framework Usage and Migrations with SQL SERVER.

Follow my Model:

using System;
using System.ComponentModel.DataAnnotations;
using System.Web.Mvc;

namespace ControleGCD.Models

{
    public class Certificado
    {

        [Key]
        public int CertificadoId { get; set; }
    [Display(Name ="Chave")]
    [MinLength(10,ErrorMessage ="{0} deve conter no mínimo 10 caracteres.")]
    [StringLength(50, ErrorMessage ="{0} deve conter entre 10 até 50 caracteres.")]
    [Required(ErrorMessage ="Favor preencher a {0} do Certificado")]
    public string CertificadoChave { get; set; }

    [Display(Name = "Descrição")]
    [MinLength(10, ErrorMessage = "{0} deve conter no mínimo 10 caracteres.")]
    [StringLength(50, ErrorMessage = "{0} deve conter entre 10 até 50 caracteres.")]
    [Required(ErrorMessage = "Favor preencher a {0} do Certificado")]
    public string CertificadoDescricao { get; set; }

    [Display(Name = "Preço")]
    [DisplayFormat(DataFormatString = "{0:C2}", ApplyFormatInEditMode = false, NullDisplayText = "Sem preço")]
    public decimal CertificadoPreco { get; set; }

    [Display(Name = "Compra")]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]    
    public DateTime CertificadoDtCompra { get; set; }

    [Display(Name = "Vencimento")]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
    public DateTime CertificadoDtVencimento { get; set; }

    [Display(Name = "Cadastro")]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
    public DateTime CertificadoDtCadastro { get; set; }

    [Display(Name = "Expira em (dias)")]
    public int CertificadoExpira { get { return (int)CertificadoDtVencimento.Subtract(CertificadoDtCompra).TotalDays; } }

    [Display(Name ="Status")]
    public StatusCertificado CertificadoStatus { get; set; }

    [Display (Name = "Tipo")]
    public int TipoCertificadoId { get; set; }
    public virtual TipoCertificado TipoCertificado { get; set; }

    [Display(Name = "Modelo")]
    public int ModeloCertificadoId { get; set; }
    public virtual ModeloCertificado ModeloCertificado { get; set; }

    [Display(Name = "Fornecedor")]
    public int FornecedorId { get; set; }

Note that in it I have a registration date field where I want to fill automatically with the current date and show in View create.

Follows my View:

@model ControleGCD.Models.Certificado
@{
    /**/

ViewBag.Title = "Cadastro";
}

}

I’m picking up on this... Automatically fill in the Registration Date Field with the current date. Can you help me please?

Grateful.

The most "clean" way to send a default value to the form, is to create an instance of the object and popular with the default values when giving the GET in the form ACTION:

public IActionResult Cadastrar() {
   Certificado certificado = new Certificado();
   certificado.CertificadoDtCadastro = DateTime.Now;

   return View(certificado);
}
  • Replace the method name with the correct one.

This way you can also centralize the default values of your object.

  • No problem, should work the same way, exchange Iactionresult for Actionresult

  • Gustavo, Add the two lines, the only difference is in the Return I left: Return View(). When I specified the certified obj within the parentheses it was an error. Leaving empty, the system was compiled normally and ran without showing the date.. What did I do wrong? Do I have to go through my View? Thanks again.

  • Post your controller code

  • Add my Controller to the body of my question Gustavo.

  • 1

    Strange to have given build error when adding Return View(certificate), as you use it yourself in other methods

  • Gustavo, Thank you very much man...I certainly ate ball in something... reviewing here refiz as you instructed me and it worked. I thank you.

  • Please give the answer as accept friend :)
