Hi,
What's a good approach for referencing lookup/reference data (static) that
one has loaded in a reference table.  Say for example "tax codes", which
pretty much have just the database ID and then a description field.  Some
options that come to mind:

1 - By ID - however this makes an assumption that the data always loads into
a database and gets the same IDs (i.e. when you're loading your static
reference data)?

2 - Search by description to identify the record - but obviously if one
changes the description this isn't very good.

3 - Perhaps create a specific identify/key as a new column that you use, but
is not the database Rails ID?  How's this sound?


Ideas/comments?
Tks
