I’m a newbie to web app development, MySQL, etc. and am giving Rails a
try via InstantRails 1.4 on a Windows XP SP2 platform.
I’ve created my database and tables etc. and, following the tutorial
located at Radar – O’Reilly
ruby-on-rails-revisited.html?page=1 I run the following command:
ruby script\generate scaffold caseinfo caseinfo
and I get:
F:\InstantRails\rails_apps\pidb1_development>ruby script\generate
scaffold casei
nfo caseinfo
exists app/controllers/
exists app/helpers/
exists app/views/caseinfo
exists test/functional/
dependency model
exists app/models/
exists test/unit/
exists test/fixtures/
identical app/models/caseinfo.rb
identical test/unit/caseinfo_test.rb
identical test/fixtures/caseinfos.yml
error Before updating scaffolding from new DB schema, try
creating a tab
le for your model (Caseinfo)
F:\InstantRails\rails_apps\pidb1_development>
I get the same error when trying to generte the scaffolds for any
other existing table.
Here’s the SQL script I wrote to generate the tables and fields. It
runs OK, everything’s there, and I can connect to the database as root
from the command line:
drop table if exists initcontact;
drop table if exists followups;
drop table if exists interview;
drop table if exists research;
drop table if exists baselines;
drop table if exists evidence;
drop table if exists summary;

I see that lots of others are getting this same error when trying to
generate scaffolds. Any ideas or suggestions?
Thanks.
