Custom plugin with multiple tables Nop 4.1

I am trying to write a custom plugin that creates multiple tables on install. Everything works fine with one table and the code below. but if I try to do two tables I get an Ambiguous error message

Search the internet but can not find the solution. Any help would be appreciated.

protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            modelBuilder.ApplyConfiguration(new Table1RecordMap());
            base.OnModelCreating(modelBuilder);

            //modelBuilder.ApplyConfiguration(new Table2RecordMap());
            //base.OnModelCreating(modelBuilder);
        }

Hi,

Can you share full error message?

Also make sure table names are unique and EntityMap class file.

This is the error message... The table names are unique

"Ambiguous match found."

nopCommerce version ?

latest 4.1

Have you done this before? custom plugin with two tables? Could you share how you do it?

Might be you missing register entity for table 2 in with dbContext in DependencyRegistrar file.

          // for table 1
            builder.RegisterType<EfRepository<DBTable1>>().As<IRepository<DBTable1>>()
                .WithParameter(ResolvedParameter.ForNamed<IDbContext>("your_db_context_name"))
                .InstancePerLifetimeScope();

            // for table 2
            builder.RegisterType<EfRepository<DBTable2>>().As<IRepository<DBTable2>>()
                .WithParameter(ResolvedParameter.ForNamed<IDbContext>("your_db_context_name"))
                .InstancePerLifetimeScope();

You can try this:

DependencyRegistrar;

private const string CONTEXT1_NAME = "nop_object_context_table1";
        private const string CONTEXT2_NAME = "nop_object_context_table2";

Then in Register;

 //data context
            builder.RegisterPluginDataContext<Table1DataObjectContext>(CONTEXT1_NAME);
            builder.RegisterPluginDataContext<Table2DataObjectContext>(CONTEXT2_NAME);

            //override required repository with our custom context
            builder.RegisterType<EfRepository<Table1>>().As<IRepository<Table1>>()
                .WithParameter(ResolvedParameter.ForNamed<IDbContext>(CONTEXT1_NAME))
                .InstancePerLifetimeScope();
            //override required repository with our custom context
            builder.RegisterType<EfRepository<Table2>>().As<IRepository<Table2>>()
                .WithParameter(ResolvedParameter.ForNamed<IDbContext>(CONTEXT2_NAME))
                .InstancePerLifetimeScope();

Take a look at Pickup in Store Plugin DependencyRegistrar in Infrastructure folder.

That sure did help but now I am stuck on the OnModelCreating part... How do I pass more then one entity to the OnModelCreating. Any Idea?

protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            modelBuilder.ApplyConfiguration(new Table1RecordMap());
            modelBuilder.ApplyConfiguration(new Table2RecordMap());
            base.OnModelCreating(modelBuilder);
        }

I am not sure if it is possible that way but I always create new DataObjectContext for each context. You will have 2 DataObjectContex File

//data context
            builder.RegisterPluginDataContext<Table1DataObjectContext>(CONTEXT1_NAME);//First One
            builder.RegisterPluginDataContext<Table2DataObjectContext>(CONTEXT2_NAME);//Second One
