Alternative to create a table when number of Category instances is fixed/limited?

Question

My app will only have three instances of the model Category - "Published", "Draft", "Unpublished".

Instinctively it feels redundant to create a table for this.

I'm thinking of storing the three category titles in a Constant instead, but I don't know where the best place is to put the Constant such that it can be referenced by multiple models.

Is there any better solution to this, or am I overthinking the issue all together (i.e. should I just create a "normal" model class/table)?

"Just" referencing to them from other models, as if they would have ID keys. — Fellow Stranger, Apr 03 '14 at 11:27
Yea, you're right. After some consideration I'll go with a ActiveRecord::Base class. I'd need all ORM benefits. — Fellow Stranger, Apr 03 '14 at 16:15

An initializer file would be best suited to define those constants. Better yet, use configatron.

You need an enum. But Ruby doesn't have enums - so see this instead - Enums in Ruby
