Castle AR 使用 Nullables 支持初态为 null 的数值属性

NullableModel.cs

namespace Castle.ActiveRecord.Tests.Model
{
    using System;

    using Nullables;

    [ActiveRecord]
    public class NullableModel : ActiveRecordBase
    {
        private int id;
        private NullableInt32 age;
        private NullableDateTime completion;
        private NullableBoolean accepted;

        public NullableModel()
        {
        }

        [PrimaryKey]
        public int Id
        {
            get { return id; }
            set { id = value; }
        }

        [Property]
        public NullableInt32 Age
        {
            get { return age; }
            set { age = value; }
        }

        [Property]
        public NullableDateTime Completion
        {
            get { return completion; }
            set { completion = value; }
        }

        [Property]
        public NullableBoolean Accepted
        {
            get { return accepted; }
            set { accepted = value; }
        }

        public static void DeleteAll()
        {
            ActiveRecordBase.DeleteAll( typeof(NullableModel) );
        }

        public static NullableModel[] FindAll()
        {
            return (NullableModel[]) ActiveRecordBase.FindAll( typeof(NullableModel) );
        }

        public static NullableModel Find(int id)
        {
            return (NullableModel) ActiveRecordBase.FindByPrimaryKey( typeof(NullableModel), id );
        }
    }
}

NullableTestCase.cs

namespace Castle.ActiveRecord.Tests
{
    using System;

    using NUnit.Framework;

    using Castle.ActiveRecord.Tests.Model;


    [TestFixture]
    public class NullablesTestCase : AbstractActiveRecordTest
    {
        [SetUp]
        public void Init()
        {
            ActiveRecordStarter.Initialize( GetConfigSource(), typeof(NullableModel) );
    
            Recreate();
        }

        [Test]
        public void Usage()
        {
            NullableModel model = new NullableModel();
            model.Save();

            Assert.AreEqual(1, NullableModel.FindAll().Length);

            model = NullableModel.FindAll()[0];

            Assert.AreEqual(Nullables.NullableInt32.Default, model.Age);
            Assert.AreEqual(Nullables.NullableDateTime.Default, model.Completion);
            Assert.AreEqual(Nullables.NullableBoolean.Default, model.Accepted);
        }
    }
