Activity: Adding a Supplier Entity that Denotes the Supplier of a Product

Scenario

You want to add a supplier entity that denotes the supplier of a product.

Aim

Add a supplier entity for a product.

Steps for completion

1. We can add Supplier class as follows:

Go to https://goo.gl/pTCc56 to access the code.

namespace RestBuy.Entities
{
  class Supplier : BaseEntity
  {
    public string Name { get; set; }
  }
}

Optionally we can add a Supplier property to Product or a SupplierId depending on if we want them to be in the same aggregate or not. This is a design choice.

2. And for the migrations we use the following code:

void ConfigureSupplier(EntityTypeBuilder<Supplier>builder)
{
  builder.ToTable("Suppliers");
  builder.HasKey(ci => ci.Id);
  builder.Property(ci => ci.Name)
  .IsRequired()
  .HasMaxLength(50);
  builder.HasIndex(c => c.Name).IsUnique();
}
