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_does_ imply that you may be using a slightly outdated tutorial.)

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

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