Creating Data Types Programmatically

You create a data type programmatically by creating a corresponding interface inherited from IData. You should specify a number of type attributes for the interface as well as add a number of properties with a number of property attributes.

Sample:

using System;
using Composite.Data;

namespace Demo
{
    [AutoUpdateble]
    [KeyPropertyName("Id")]
    [ImmutableTypeId("{6EF1F9CC-D14B-4c63-AF4C-662089BFEDEA}")]
    [DataScope(DataScopeIdentifier.PublicName)]
    public interface IMyUser : IData
    {
        [ImmutableFieldId("{62A03F88-4A29-4182-9BCF-84080F1A2111}")]
        [StoreFieldType(PhysicalStoreFieldType.Guid)]
        Guid Id { get; set; }


        [ImmutableFieldId("{6AEEA24A-77AB-486c-AE6F-69EB224735A4}")]
        [StoreFieldType(PhysicalStoreFieldType.String, 64)]
        string Name { get; set; }


        [ImmutableFieldId("{6A085CAD-E74E-4e4b-8352-B31D9932EDCC}")]
        [StoreFieldType(PhysicalStoreFieldType.String, 64)]
        string Email { get; set; }
    }
}

In the sample:

• The ImmutableTypeId attribute specifies a unique ID for the type.
• The KeyPropertyName attribute specifies the name of the key property used as a key for the data type.
• The DataScope attribute specifies data scopes items of the data types should exist in (DataScopeIdentifier.Public and DataScopeIdentifier.Administrated).
• The AutoUpdate attribute has C1 CMS automatically add and update your type.
• The ImmutableFieldId attribute specifies a unique ID for the property.
• The StoreFieldType specifies the underlying type of the property.
