Generating Code for Tenants Table

Launch Sergen and generate code for Tenants table in Default connection:

• Connection: Default
• Table Name: dbo.Tenants
• Module Name: Administration
• Identifier: Tenant
• Permission Key: Administration:Tenants

Next we'll define a lookup script in TenantRow and set DisplayName property to Tenants:

namespace MultiTenancy.Administration
{
    //...
    [ConnectionKey("Default"), DisplayName("Tenants"), 
     InstanceName("Tenant"), TwoLevelCached]
    [LookupScript("Administration.Tenant")]
    public sealed class TenantRow : Row, IIdRow, INameRow
    {
        [DisplayName("Tenant Id"), Identity]
        public Int32? TenantId
        {
            get => Fields.TenantId[this];
            set => Fields.TenantId[this] = value;
        }

//...

Let's define a Administration:Tenants permission that only admin user will have (in AdministrationPermissionKeys.cs):

namespace MultiTenancy.Administration
{
    [NestedPermissionKeys]
    [DisplayName("Administration")]
    public class PermissionKeys
    {
        [Description("User, Role Management and Permissions")]
        public const string Security = "Administration:Security";

        [Description("Languages and Translations")]
        public const string Translation = "Administration:Translation";

        [Description("Tenant Management")]
        public const string Tenants = "Administration:Tenants";
    }
}

And use it on TenantRow:

[ConnectionKey("Default"), DisplayName("Tenants"), 
 InstanceName("Tenant"), TwoLevelCached]
[ReadPermission(PermissionKeys.Tenants)]
[ModifyPermission(PermissionKeys.Tenants)]
[LookupScript("Administration.Tenant")]
public sealed class TenantRow : Row, IIdRow, INameRow
{
