The entity type AuditLog is not part of the model for the current context.

Issue

I intermittently get the following error:

System.InvalidOperationException: The entity type AuditLog is not part of the model for the current context.

I have difficulty reproducing the error and when I do, there doesn’t seem to be any kind of pattern.

Code

DatabaseContext.cs

public class DatabaseContext : AuditDbContext
{
        public DatabaseContext(string contextName) : base(contextName)
        {
            Configuration.LazyLoadingEnabled = false;
            Configuration.ProxyCreationEnabled = false;

            ConfigureAuditNet();
        }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            modelBuilder.Entity<AuditLog>().ToTable("AuditLogs");

            base.OnModelCreating(modelBuilder);       
        }

        private void ConfigureAuditNet()
        {
            Audit.Core.Configuration.Setup()
                .UseEntityFramework(_ => _
                    .AuditTypeMapper(t => typeof(AuditLog))
                    .AuditEntityAction<AuditLog>((ev, entry, entity) =>
                    {
                        entity.AuditData = entry.ToJson();
                        entity.EntityType = entry.EntityType.Name;
                        entity.AuditDate = DateTime.Now;
                        entity.AuditUserId = HttpContext.Current.User.GetUserIdInt();
                        entity.TablePk = entry.PrimaryKey.First().Value.ToString();
                    })
                    .IgnoreMatchedProperties(true));

            Audit.EntityFramework.Configuration.Setup()
                .ForContext<DatabaseContext>()
                .UseOptOut()
                    .Ignore<Heartbeat>();
        }

        public DatabaseContext() : base("name=OPv2Database") { }
 
       public DbSet<AuditLog> AuditLogs { get; set; }
       .
       .
       .
       // some more models
}

How I save to the database.

public void AddShopOrderNotes(List<ShopOrderNote> shopOrderNotes)
{
            using (var context = new DatabaseContext(_connectionName))
            {
                context.ShopOrderNotes.AddRange(shopOrderNotes);

                context.SaveChanges();
            }
}

This will work anywhere from 80% - 95% of the time. The other times it will fail, then the user will save again immediately and it will work.

Please let me know if you need any other information. I’m stumped on what it could be and I’m willing to try any suggestions.

That’s the way to go. The data provider should be set just once, since it’s a global static property (Audit.Core.Configiration.DataProvider)

And thank you very much for your kind words 😃

Now it saves and I don’t get any errors after doing this:

Audit.EntityFramework.Configuration.Setup()
                .ForContext<DatabaseContext>()
                .UseOptOut()
                    .Ignore<AuditLog>()
                    .Ignore<Heartbeat>();
