Create Datatypes
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:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | 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
ImmutableTypeIdattribute specifies a unique ID for the type. - The
KeyPropertyNameattribute specifies the name of the key property used as a key for the data type. - The
DataScopeattribute specifies data scopes items of the data types should exist in (DataScopeIdentifier.PublicandDataScopeIdentifier.Administrated). - The
AutoUpdateattribute has C1 CMS automatically add and update your type. - The
ImmutableFieldIdattribute specifies a unique ID for the property. - The
StoreFieldTypespecifies the underlying type of the property.
