I have a general question about whether people think you should use a database table or constants hashes/arrays for categories. I’m torn on which way to go. Thoughts?

    Well, if you are 100% sure you won’t ever change the categories, you could go for a custom model with the Object superclass (no DB-table and no ActiveRecord).

    If you ever would change a category or add any you want a database. This is because your models won’t get reloaded after a change in production mode.

    I still recommend a database anyway because of at least the following:

    1. See MattC’s comment.
    2. You can use ActiveRecord relationships (has_many and belongs_to). This is hard to do without ActiveRecord.
    3. The performance decrese is not significant. It might slow down 0.2ms at most.
