Entity Framework Code First Date field creation

Question

I am using Entity Framework Code First method to create my database table. The following code creates a DATETIME column in the database, but I want to create a

Answer 1

I found this works in EF6 nicely.

I created a convention for specifying my data types. This convention changes the default DateTime data type in the database creation from datetime to datetime2. It then applies a more specific rule to any properties that I have decorated with the DataType(DataType.Date) attribute.

public class DateConvention : Convention
{
    public DateConvention()
    {
        this.Properties()
            .Configure(c => c.HasColumnType("datetime2").HasPrecision(3));

        this.Properties()
            .Where(x => x.GetCustomAttributes(false).OfType()
            .Any(a => a.DataType == DataType.Date))
            .Configure(c => c.HasColumnType("date"));
    }
}

Then register then convention in your context:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    modelBuilder.Conventions.Remove();
    modelBuilder.Conventions.Add(new DateConvention());
    // Additional configuration....
}

Add the attribute to any DateTime properties that you wish to be date only:

public class Participant : EntityBase
{
    public int ID { get; set; }

    [Required]
    [Display(Name = "Given Name")]
    public string GivenName { get; set; }

    [Required]
    [Display(Name = "Surname")]
    public string Surname { get; set; }

    [DataType(DataType.Date)]
    [Display(Name = "Date of Birth")]
    public DateTime DateOfBirth { get; set; }
}
