Rails - Jan 2009 - Help using a rake task to add items to my database?

Once a month or so, I''d like to pull data from an RSS feed and add it
into my database. I''ve written a rake task that properly reads the
feed, parses it and assigns the correct information to new instances
of my @event model - when I run the rake task and have it print out
the various @event attributes, they''re correct. However, when I
include the command @event.save nothing happens.

In fact, when I added this code

if @event.save
      puts "Event saved"
    else
      puts "Event not saved, bummer"

I got "Event not saved, bummer"

Is it possible to use a rake task to add entries to my application''s
database? If so, any suggestions as to what I might be doing wrong?
I''m testing this in my development environment, and I start my task
definition using

task (:parse_info => :environment) do

Any suggestions would be greatly appreciated. Thanks.

Try this and see what is printed:

if @event.save
    puts "Event saved"
else
    puts @event.errors.full_messages.inspect
end

What you''re doing sounds right, most likely though you have a
validation that is keeping the model from saving.

Yes, thank you so much, that''s exactly it! A nil value for one of the
attributes was triggering an error, because there''s a validation for a
maximum value. I gather a maximum value validation requires there to
be a value to check and not nil. Changing that attribute to a
string="" for all the entries solved the problem.
