Generate money type fields using code first EF CTP5

Question

In this blog post: EF4 Code First Control Unicode and Decimal Precision, Scale with Attributes, Dane Morgridge used attributes to control the creation of different types on your database.

...And I found this pretty unique BTW!!!

How do I generate money type fields in my resulting database using code first API of EF CTP5, if is possible to do it from your model, using conventions or attributes?

Sorry about my English is not my main language.

Thanks in advance.

Answer 1

For example, consider this Invoice class:

public class Invoice {     public int InvoiceId { get; set; }                     public decimal Amount { get; set; } } 

You can do it with fluent API:

protected override void OnModelCreating(ModelBuilder modelBuilder) {     modelBuilder.Entity<Invoice>()                 .Property(i => i.Amount)                 .HasColumnType("Money"); } 

Or you can do it with Data Annotations:

public class Invoice {     public int InvoiceId { get; set; }                      [Column(TypeName="Money")]     public decimal Amount { get; set; } } 

Answer 2

using System.Data.Entity.ModelConfiguration.Configuration.Properties.Primitive;

public class MoneyAttribute : Attribute { }

public class MoneyAttributeConvention : AttributeConfigurationConvention<PropertyInfo, DecimalPropertyConfiguration, MoneyAttribute> {
    public override void Apply(PropertyInfo memberInfo, DecimalPropertyConfiguration configuration, MoneyAttribute attribute) {
        configuration.ColumnType = "money";
    }
}

then you use like that

[Money]
public decimal Value { get; set; }
