Thanks for this
I am reading through the "blackbook" on Rails and various web resources.
I should start to be able to produce something concrete in a month or so.
It would be an interesting exercise to try and migrate a legacy DB such
as Pracsoft to a rails DB. If the DB schema is known this should be
possible using a Ruby script.

Hi Richard,
If you follow the rails method, your program would take off by
following these 2 quick steps : 1) almost always name your sql
tables in the plural form e,g. transactions, items, patients etc
2) change your directory to the appropriate application folder, then
execute: script/generate scaffold Transaction Accountant
This will generate the model (named in the singular form of the
table name by convention) called Transaction as the table is named
Transactions, and the controller called Accountant. in this
instance....
and away you go with the basic CRUD already set up for you once you
launch webbrick.

Doesnt RoR have a method to convert singular names to plural? In this
case it seems better to use the singular.
autogenerated models assume plural
you can manually override it with the table statement to any name
you choose
(eg for legacy database integration)
As always in RoR - convention over configuration. You can ignore the
convention whenever you like at the price of having to add
configuration
information manually
PS: there is a RoR gem called db_discovery or similar, from memory)
which you
can point at legacy databases and it just goes through and
automatically
generates all models and migration code from introspection and metadata
analysis - regardless of tablenames etc.
