如何首先使用 trackerenableddbcontext 在 asp.net mvc5 和代码中的实体框架中实现审计跟踪

Question

我正在使用 Entity framework 和代码优先迁移开发 MVC5 应用程序，我想实施审计跟踪。我找到了一个名为 trackerenableddbcontext 的 NuGet 包，它看起来很容易使用。然而，我确实安装了这个包，并做了以下代码，但仍然没有任何东西被添加到审计中 table.

我已经实现了从Tracker Context继承的，如代码所示

DBContext class
public class SIContext : TrackerContext //DbContext
{
    public SIContext()
        : base("name=SIConnectionString")
    {
    }


    public virtual DbSet<Role> Roles { get; set; }
    public virtual DbSet<User> Users { get; set; }
    public virtual DbSet<Menu> Menus { get; set; }
    public virtual DbSet<MenuPermission> MenuPermissions { get; set; }
    public virtual DbSet<ProductCategory> ProductCategorys { get; set; }
    public virtual DbSet<Product> Products { get; set; }

    public virtual DbSet<GRV> GRVs { get; set; }
    public virtual DbSet<Artisans> Artisans { get; set; }
    public virtual DbSet<JobCard> JobCards { get; set; }
    public virtual DbSet<Order> Orders { get; set; }
    public virtual DbSet<InternalRequisitionForm> InternalRequisitionForms { get; set; }
    public virtual DbSet<JobRequisition> JobRequisitions { get; set; }

    public virtual DbSet<GRVMaterials> GRVMaterials { get; set; }
    public virtual DbSet<Quotation> Quotations { get; set; }
    public virtual DbSet<QuotationItems> QuotationItems { get; set; }
    public virtual DbSet<DNoteMaterial> DNoteMaterials { get; set; }
    public virtual DbSet<InvoiceMaterials> InvoiceMaterial { get; set; }






    //
    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {

        modelBuilder.Configurations.Add(new ShopMate.Maping.RoleMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.UserMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.MenuMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.MenuPermissionMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.ProductCategoryMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.ProductMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.TaxMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.ProductStockMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.PaymentModeMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.SaleMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.InvoiceItemsMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.SettingMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.InvoiceFormatMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.InventoryTypeMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.PurchaseMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.TransactionMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.InvoiceMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.LedgerAccountMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.WarehouseMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.DuePaymentMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.ExpenseMap());
        modelBuilder.Configurations.Add(new ShopMate.Maping.InternalRequisitionFormMap());



        base.OnModelCreating(modelBuilder);
    }


}

Table我要跟踪

[TrackChanges]
public class Product
{
    [DisplayName("S.No")] 
    public int Id { get; set; }
    [Required]
    [StringLength(100)] 
    [DisplayName("Name")] 
    public string Name { get; set; }
    [Required]
    [DisplayName("Product Category")] 
    public int? ProductCategoryId { get; set; }
    public virtual ProductCategory ProductCategory_ProductCategoryId { get; set; }
    [StringLength(100)] 
    [DisplayName("Bar Code")] 
    public string BarCode { get; set; }
    [Required]
    [DisplayName("Purchase Price")] 
    public Decimal PurchasePrice { get; set; }
    [Required]
    [DisplayName("Sale Price")] 
    public Decimal SalePrice { get; set; }
    [DisplayName("Product Image")] 
    public string ProductImage { get; set; }
    [DisplayName("Added By")] 
    public Nullable<int> AddedBy { get; set; }
    [DisplayName("Date Added")] 
    public Nullable<DateTime> DateAdded { get; set; }
    [DisplayName("Modified By")] 
    public Nullable<int> ModifiedBy { get; set; }
    [DisplayName("Date Modied")] 
    public Nullable<DateTime> DateModied { get; set; }
    [Required]
    [DisplayName("Is Active")] 
    public bool IsActive { get; set; }
    [Required]
    [DisplayName("Stock Alert")] 
    public int StockAlert { get; set; }
    [DisplayName("Tax")] 
    public Nullable<int> TaxId { get; set; }
    [Required]
    [DisplayName("Warehouse")] 
    public int WarehouseId { get; set; }

    [DisplayName("Discount")]
    public Nullable<Decimal> Discount { get; set; }

    [DisplayName("Remaining Quantity")]
    public Nullable<Decimal> RemainingQuantity { get; set; }

    [DisplayName("Remaining Amount")]
    public Nullable<Decimal> RemainingAmount { get; set; }

    [StringLength(100)]
    [DisplayName("HSN")]
    public string HSN { get; set; }

    public virtual ICollection<ProductStock> ProductStock_ProductIds { get; set; }
    public virtual ICollection<Sale> Sale_ProductIds { get; set; }
    public virtual ICollection<InvoiceItems> InvoiceItems_ProductIds { get; set; }
    public virtual ICollection<Purchase> Purchase_ProductIds { get; set; }
}}

控制器功能

[HttpPost]
   [ValidateAntiForgeryToken]
   [ValidateInput(false)]
    public ActionResult Edit(Product ObjProduct, HttpPostedFileBase ProductImage, string HideImage1)
    {
        System.Text.StringBuilder sb = new System.Text.StringBuilder();
        int userId = Convert.ToInt32(Env.GetUserInfo("userid"));
        try
        {

            if (ModelState.IsValid)
            {
                if (ProductImage != null)
                {
                    var fileName = MicrosoftHelper.MSHelper.StarkFileUploaderCSharp(ProductImage, Server.MapPath("~/Uploads"));
                    ModelState.Clear();
                    ObjProduct.ProductImage = fileName;
                }
                else
                {
                    ObjProduct.ProductImage = HideImage1;
                }


                db.Entry(ObjProduct).State = EntityState.Modified;

                db.SaveChanges(userId);

                sb.Append("Sumitted");
                return Content(sb.ToString());
            }
            else
            {
                foreach (var key in this.ViewData.ModelState.Keys)
                {
                    foreach (var err in this.ViewData.ModelState[key].Errors)
                    {
                        sb.Append(err.ErrorMessage + "<br/>");
                    }
                }
            }
        }
        catch (Exception ex)
        {
            sb.Append("Error :" + ex.Message);
        }


        return Content(sb.ToString());

    }

我希望它将更改保存到数据库、audidlog 和 auditlogdetails tables。

当您在 DBContext 中使用附加实体时，您需要在应用程序启动时添加 GlobalTrackingConfig.DisconnectedContext = true;。
