The problem you're running into has to do with encoding mismatch

Hi Yoram,
There are lots of different approaches, especially depending on what
your app does and how it is implemented, but I usually do something
like the following, which works for both development env (setup to re-
reload all code/templates/etc on each request) and production env
(setup to re-
Instead of fastcgi, you might want to look into using mongrel (http://
mongrel.rubyforge.org) instead:

One of the things I've loved about rails is the ease with which you
can leverage your existing app code for shell/cli/scripting purposes
using ./script/console and ./script/runner. As such, I highly
recommend implementing your parsing/processing code from within your

To initialize some db-read var (tidbit in your example) that would
survive and be callable for each subsequent app request, you'll want
to do so via lazy-initialization using a before_filter (mentioned by
bill) in application.rb.
How you store such lazy-init vars between requests depends on the

I agree with Bill. pdftk has been an invaluable tool for me when
working with pdfs, and can easily be wrapped for use in ruby.
Altho you'll want to add checks to ensure safety of params your
passing to pdftk, and check for errors returned, ..., you could do
something like:

Hi John,
Hard to tell, but I'm wondering if you forgot to run rake:db:migrate
after running rake db:sessions:create? The latter creates the
migration file in db/migration/, and the former actually creates the
table in the db. Check your db to make sure the sessions table does
exist.

Hi Salil,
To convert xls to csv and then parse for use in ruby, you could try
wrapping xls2csv (http://www.wagner.pp.ru/~vitus/software/catdoc/) and
parsing via CSV (http://www.ruby-doc.org/stdlib/libdoc/csv/rdoc/
index.html), something like:
$ irb
irb(main):001:0> require 'csv'
=> true

Hi Greg,
Here's a simple mysql-specific example for adding cascade delete
constraint, for authors0..*books, that should give you an idea of
what to do in your oracle proj (using oracle-specific constraints):
# in config/environment.rb:
...
config.active_record.schema_format = :sql

Hi Frank,
What you need to do is a bit of http client programming. There are
lots of options, including:

Whatever you use depends on your needs/tastes.
