ASP .NET MVC 5 Validation and Way to change standard validation message

my view

@model Riski.Models.Koef

@using (Html.BeginForm()) {
    

    @Html.AntiForgeryToken()
    




@Model.name



@Html.ValidationSummary(true, "", new { @class = "text-danger" })

            

            


@Html.LabelFor(model => model.koef1, htmlAttributes: new { @class = "control-label col-md-2" })
                


@Html.EditorFor(model => model.koef1, new { @class = "form-control" })
                    @Html.ValidationMessageFor(model => model.koef1, "", new { @class = "text-danger" })
                

@Html.HiddenFor(model => model.id)
            @Html.HiddenFor(model => model.name)


        




            


}


@Html.ActionLink("Вернуться к списку", "Index")

@section scripts{
    @Scripts.Render("~/bundles/jqueryval")
}

my controller

        [HttpPost]
        public ActionResult Edit(Koef koef)
        {
            if (ModelState.IsValid)
            {
                db.Configuration.ValidateOnSaveEnabled = false;

                db.Koefs.Attach(koef);
                var entry = db.Entry(koef);
                entry.Property(e => e.koef1).IsModified = true;

                db.SaveChanges();
                return RedirectToAction("Index");
            }
            return View(koef);
        }

this is a partial class wich helps us to validate our model. Acording to this approach we don't need to add Validation Attributies after every process of generation Entity classes

using System;
using System.ComponentModel.DataAnnotations;

namespace Riski.Models
{
    [MetadataType(typeof(KoefViewModel))]
    public partial class Koef
    {
    }

    public class KoefViewModel
    {
        [Required]
        [Display(Name = "Коэффициент")]
        [Range(0, 100, ErrorMessage = "Значение должно быть от 0 до 100.")]
        public Nullable koef1 { get; set; }

        [Required]
        public int id { get; set; }
    }
}

That's it. Now , as this is a russian web-site, we need to override some standard validation messages. It's simple solution and we should do only for steps

1 Add folder

2 Create resource file

3 Add new value (We can override 4 types of messages FieldMustBeDate, FieldMustBeNumeric, PropertyValueInvalid andPropertyValueRequired)

4 And add one line to your Global.asax.cs

DefaultModelBinder.ResourceClassKey = "MyNewResource";
