Hi!
I've been wrecking my mind on how to get my tagging of entities to work. I'll get right into some database structuring:
tblTag
TagId - int32 - PK
Name
tblTagEntity
TagId - PK
EntityId - PK
EntityType - string - PK
tblImage
ImageId - int32 - PK
tblBlog
BlogId - int32 - PK
class Image
Id
EntityType { get { return "MyNamespace.Entities.Image"; }
IList Tags;
class Blog
Id
EntityType { get { return "MyNamespace.Entities.Blog"; }
IList Tags;
The obvious problem I have here is that EntityType is an identifer but doesn't exist in the database. If anyone could help with the this mapping I'd be very grateful.
