rake aborted (wrong number of arguments)

[Ryan Ororie]

I'm following a tutorial here to get some columns in my database. I
generated a model called 'product' then I edited
'db/001_create_products.rb' to have a few columns but when I try to
migrate I get this error:

bio4054059:depot rmorourk$ rake db:migrate
(in /Users/rmorourk/Sites/depot)
== CreateProducts: migrating
==================================================
-- create_table(:products)
rake aborted!
wrong number of arguments (1 for 2)

(See full trace by running task with --trace)
bio4054059:depot rmorourk$

I copied the code exactly for the 001_create_products.rb not really sure
what it means by wrong number of arguments... any advise would be
welcomed happily!

What does 001_create_products.rb look like?

(BTW, if your migration filenames look like that, your tutorial may be
for an older version of Rails. If you use script/generate migration,
newer versions of Rails will use a timestamp, so that the filename
might be something like 20081217040235_create_products.rb . That's
not a big deal in itself -- either naming scheme will work -- but it
*does* imply that you may be using a slightly outdated tutorial.)

Best,

It looks like this - is there something wrong with it?

class CreateProducts < ActiveRecord::Migration
def self.up
create_table :products do |t|
t.column :title; :string
t.column :description; :text
t.column :image_url; :string
end
end

def self.down
drop_table :products
end
end

    end

  def self.down
    drop_table :products
  end
end
  

I believe those are supposed to be commas not semi-colons after the column names.
