I want to update values in my database. to make sure my script was working and to send the values I created a POST method to check and the values are coming.
My question now is with the values coming to the method, how to update or save my values in the database?
Controller:
[HttpPost] public JsonResult EditPost(Programa_Cor_Info_Status statusData) { Programa_Cor_Info_Status status = new Programa_Cor_Info_Status { ID_Info = statusData.ID_Info, Status = statusData.Status, Obs = statusData.Obs, }; return Json(status, JsonRequestBehavior.AllowGet); }
I tried using db.savechanges on my controller but to no avail.
Could someone help me with an example?
Thanks
————Update—————————————–
[HttpPost] public ActionResult EditPost(Programa_Cor_Info_Status statusData, int ID_Status) { Programa_Cor_Info_Status status = new Programa_Cor_Info_Status { ID_Info = statusData.ID_Info, Status = statusData.Status, Obs = statusData.Obs, }; var q = db.Programa_Cor_Info_Status.Where(m => m.ID_Info == ID_Status).FirstOrDefault(); q.ID_Info = ID_Status; db.Entry(q).State = EntityState.Modified; db.SaveChanges(); return Json(status, JsonRequestBehavior.AllowGet); }

namespace Balu0._1.Models { using System; using System.Collections.Generic; public partial class Programa_Cor_Info_Status { public int ID_Info { get; set; } public int ID_Programa { get; set; } public int ID_Linha_Cor { get; set; } public string Status { get; set; } public string Obs { get; set; } } }

Method 1
If you stll don’t have, in your view add hidden model field with ID_Info value.
Change your action to this:
public ActionResult EditPost(Programa_Cor_Info_Status statusData) { var existItem = db.Programa_Cor_Info_Status.Find(statusData.ID_Info); // or if you dont have a proper primary key you can try var existItem = db.Programa_Cor_Info_Status .Where( i=> i.ID_Info== statusData.ID_Info).FirstOrDefault(); if (existItem != null) { db.Entry(existItem).CurrentValues.SetValues(statusData); var result = db.SaveChanges(); // if result==0 then error } else ...error return Json(statusData, JsonRequestBehavior.AllowGet); }
Method 2
thanks for the help i already got !!!
db.Entry(status).State = EntityState.Modified; db.SaveChanges(); return Json(status, JsonRequestBehavior.AllowGet);
