Hello team,
I'm writing a plugin that needs to persist data to database table. I successfully enable migration but having trouble adding migration. I get the below exception:
PM> add-migration GTPayInit
System.InvalidOperationException: Unable to determine the principal end of an association between the types 'SmartStore.Core.Domain.Customers.RewardPointsHistory' and 'SmartStore.Core.Domain.Orders.Order'. The principal end of this association must be explicitly configured using either the relationship fluent API or data annotations.

Unable to determine the principal end of an association between the types 'SmartStore.Core.Domain.Customers.RewardPointsHistory' and 'SmartStore.Core.Domain.Orders.Order'.

No modification was done to either SmartStore.Core.Domain.Orders.Order nor SmartStore.Core.Domain.Customers.RewardPointsHistory nor their mappings. I successfully added migration to SmartStore.Data. Why is that of the plugin failing? The code for the plugin ObjectContext is shown below:
public class GTPayObjectContext : ObjectContextBase
{
public const string ALIASKEY = "sm_object_context_gtpay";
static GTPayObjectContext()
{
var initializer = new MigrateDatabaseInitializer<GTPayObjectContext, Configuration>
{
TablesToCheck = new[] { "GTPaySupportedCurrency", "GTPayTransactionLog", "GTPayTransactionStatus" }
};
Database.SetInitializer(initializer);
}
/// <summary>
/// For tooling support, e.g. EF Migrations
/// </summary>
public GTPayObjectContext()
: base()
{
}
public GTPayObjectContext(string nameOrConnectionString)
: base(nameOrConnectionString, ALIASKEY)
{
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Configurations.Add(new GTPayTransactionLogRecordMap());
modelBuilder.Configurations.Add(new GTPaySupportedCurrencyRecordMap());
modelBuilder.Configurations.Add(new GTPayTransactionStatusRecordMap());
//disable EdmMetadata generation
//modelBuilder.Conventions.Remove<IncludeMetadataConvention>();
base.OnModelCreating(modelBuilder);
}
}
Please assist, and thank you in advance.
