com.gudang2go.Sequence 4.0.1

Sequence Tracker (Get Next Sequence)
Requiremet:

• Download package:

      com.gudang2go.Sequence.Domain,
      com.gudang2go.Sequence.Infrastructure,
      com.gudang2go.Sequence.Shared
  

Usage:

• Implement ITrackerUpdaterContext to UpdaterDbContext

  using com.gudang2go.Sequence.Shared.Enums;
  
  public class UpdaterDbContext : DbContext, IRMQDBContext, ITrackerUpdaterContext
  {
      public UpdaterDbContext(DbContextOptions<UpdaterDbContext> options, IConfiguration configuration) : base(options) { }
  
      public DbSet<Tracker> SequenceTrackers { get; set; }
  
      protected override void OnModelCreating(ModelBuilder modelBuilder)
      {
          modelBuilder.ApplyConfiguration(new TrackerConfiguration("YOUR_MODULE_SCHEMA_NAME", 
              [SourceTypeEnum.SalesOrder, SourceTypeEnum.DeliveryOrder] // => create the sequence needed for the module
          ));
      }
  }
  
  

• Implement ITrackerViewerContext to ViewerDbContext

  using S = com.gudang2go.Sequence.Domain.AggregateModels.SequenceAggregate;
  using com.gudang2go.Sequence.Infrastructure.EntityConfigurations;
  
  public class ViewerDbContext : DbContext, IRMQDBContext, ITrackerViewerContext 
  { 
      public ViewerDbContext(DbContextOptions<ViewerDbContext> options, IConfiguration configuration) : base(options) { }
  
      public DbSet<S.Sequence> Sequences { get; set; }
  
      protected override void OnModelCreating(ModelBuilder modelBuilder)
      {
          modelBuilder.ApplyConfiguration(new SequenceEntityTypeConfiguration());
      }
  }
  
  

• Inject service to Program.cs

  builder.Services.AddTrackerService<UpdaterDbContext, ViewerDbContext>();
  

• Before using the service, migrate the table first then use the service

  using com.gudang2go.Sequence.Shared.Enums;
  
  private readonly ITrackerService<UpdaterDbContext, ViewerDbContext> _trackerService;
  
  public Constructor(ITrackerService<UpdaterDbContext, ViewerDbContext> trackerService)
  {
      _trackerService = trackerService;
  }
  
  public async Task YourFunction()
  {
      // Output will be a string
      var sequence = await _trackerService.GetNextSequence(SourceTypeEnum.SalesOrder); // => Adjust the Enum
  }
