Missing AR

with 5 comments

Part of my new year resolution was to get rid off AR from my application architecture design replace it with pure NHibernate. But since AR had been my tool of choice for almost a year or so it just keep haunting me every now and then.

I believe the feature of AR that I am going to talk about is pretty old but somehow useful for certain situation; so let see.

Say you have to deal with User & User’s Roles scenario. A user can play many roles isn’t she? Now pretend you are a lazy developer / no because your DBA was lazy to create a Role, UserRoles table for you :) I know, I know I don’t think this will happen in the real world, your DBA can’t be that naughty :D but anyway one in a while if you were like me learn and love IPrincipal interface everytime I setup a User class you know that the IsInRole(string) will smile at you if it had to deal with Role stored as array of string.

public class User {

   public virtual int Id { get; set; }

   public virtual string Name { get; set; }

   public virtual string[] Roles { get; set; }


No hack, No tweak simply sweet how can’t I miss the AR ;)

  1. I have no much idea about coding but I know it makes the synergy when combined with business concept. Let’s take XBRL as example. More info on stockcam’s blog. You may have some ideas on this application or you may create another initiative one :-)

  4. Allthough this has nothing to do with you post, I was wondering how you got those nice code embeddings?
