Seed/Migrate Enum to Table with Entity Framework

My latest project included integrating employees into Active Directory via 3rd party API.    I successfully did so, but afterward, my team requested some sort of log to monitor the integration.

The activity log I created included to an ActionType int that was related to an enum.  For transparency, I wanted to transfer those enums into a small table, that way those values could be easily available to our team, all of whom have SQL query skills, but are not all developers.

A simple idea and solution, to migrate enums to a table using Entity Framework, just not something I had done using CodeFirst.  Here’s how I got it working.

The log I set up is pretty straight forward and included an ActionType int.

[Table("Activity", Schema = "MyApp")]
public class MyAppActivity
{
     [Key]
     public int Id { get; set; }
     public int ActionType { get; set; }
     public DateTime UpdateDateTime { get; set; } = DateTime.Now;
     public string Response { get; set; }
     public bool Success { get; set; }

     //payload
}

That integer, ActionType, is tied to ActionTypeEnum:

public enum ActionTypeEnum
{
     DEPENDENCY_NOT_FOUND = 1,
     INVALID = 2,
     SKIP = 3,
     CREATE = 4,
     UPDATE = 5,
     REHIRE = 6,
     TERMINATE = 7
}

I created the table ActionType to hold these values:

[Table("ActionType", Schema = "MyApp")]
public class ActionType
{
     [Required, Key, DatabaseGenerated(DatabaseGeneratedOption.None)]
     public ActionTypeEnum Id { get; set; }
     public string Name { get; set; }
}

Now, to populate ActionType:

public class MyAppContext : DbContext
{
     protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
     {
          optionsBuilder.UseSqlServer("CONN_STRING_HERE");
     }

     protected override void OnModelCreating(ModelBuilder builder)
     {
          foreach (var e in Enum.GetValues(typeof(ActionTypeEnum)).Cast<ActionTypeEnum>())
          {
               builder.Entity<ActionType>().HasData(new ActionType { Id = e, Name = e.ToString() });
          }
     }

     public DbSet<MyAppActivity> MyAppActivity { get; set; }
     public DbSet<ActionType> ActionType { get; set; }
}

Quick and easy and helps my team query the data they need without need for my help.
