Plural names such as countries

Hi,
I found out that Rad Rails names could be properly made plural, such as
“country” = “countries” not “countrys”.
.
I have a database that contained one table named “countrys”. I
pluralized the name by adding an “s” as “countrys”.I ran the Rad Rails
generator and created a “controller” that was named “country index”.
Rad Rails made the plural of “country” as “countries” and I got an
error message. I went to mysql database and changed the name of the
table to “countries” and then ran the generator again. I got an error,
so I ran the generator marked as “destroy”. I then ran the generator
marked as “create”

I wondered what problem this caused me. Did I do enough by just running
generator with “destroy” or is there more to do?
Thanks for any help!
Jim
