Active Record & Repository<T>

time to read 1 min | 200 words

I am currently thinking about my next project, and I really want to use Active Record, and at the same time, I really want to be able to utilize Repository<T> and decorators chains or not.

A long time ago I made sure that Active Record will be usable without utilizing the "Active Record"-ness of it, so it wasn't that hard to build an IRepository<T> implementation for it, implementing UnitOfWork was a bit more tricky, since I wanted to keep the option to use NHibernate / Active Record at will, as always, another layer of abstraction is always the answer.

I went to such lengths mainly because I didn't want just to get the Active Record RAD capabilities, but to take advantages of the other advantages that it offers (Validation is one, ARDatabind is another, etc). I am not so sure that this is a good idea, though.

I am considerring using Active Record to just generate the mapping (since it has very strong cross-inferencing capabilities), but I am not sure if that is a good idea in the long run...

Any ideas?
