ActiveRecord: how to find constraints?

I'm kind of new to ActiveRecord (using CastleProject) and gaining knowledge step by step. Now I'm running into another situation.

I've got a Media class that is used in some other classes: Content, Case and Service. Now when I want to delete a Media class, I want to check if there are any constraints with the previous named classes. Is there a best-practice on how to achieve this? Or are there any functions within the CastleProject/Nhibernate which might help me with this?

Solution

  • If you just want to catch the database exception when violating a constraint, check out ISQLExceptionConverter.

    But if you want to find out exactly what records in other tables will trigger the constraint exception you'll have to run whatever queries are needed yourself.
