Rails - Apr 2006 - Noobie problems with helper

I have the following helper method in application_helper.rb:

  def format_date(date)
    day = to_s(date.day)
    month = to_s(date.month)
    time = to_s(date.time)

    date = day + "/" + month + " - " + time
    return date
  end

I am trying to call this method in a view like this:

<%= format_date(bounty.created_on) %>

create_on is a timestamp in mysql. I am getting this error:

ArgumentError in Bounties#index
Showing app/views/bounties/list.rhtml where line #14 raised:
wrong number of arguments (1 for 0)
Extracted source (around line #14):

11:   <tr>
12:     <td><%= bounty.bounty %></td>
13:     <td><%= bounty.customer.first_name %></td>
14:     <td><%= format_date(bounty.created_on) %></td>
15:     <td><%= link_to ''Show'', :action =>
''show'', :id => bounty %></td>
16:     <td><%= link_to ''Edit'', :action =>
''edit'', :id => bounty %></td>
17:     <td><%= link_to ''Destroy'', { :action =>
''destroy'', :id => bounty
}, :confirm => ''Are you sure?'', :post => true
%></td>

I am a ruby, rails, and programming newbie so I''m sure there is just a 
simple syntax error. Thanks for the help in advance.

Hi Jonathan,

I notice your code below uses "bounty.created_on" but you say just
below
that "create_on" is a timestamp in mysql".  If that''s
not just a typo (i.e.,
created_on vs. create_on), that''s one place to look.

hth,
Bill

sry, I meant to say that created_on is the timestamp in mysql. That was 
a typo in my post, but should be correct in the code.

The error is in your call of the to_s function. if you really want to 
format the call it as a method instead: date.day.to_s (Also, trying to 
call date.time isn''t going to work.)

Maybe you should try date.strftime instead of rolling your own handler?

Um, that should just read "Call it as a method instead ..."

good call on strftime. That''s what I''ll do instead. I guess I
should
read the ruby manual and not just the rails manual :) Thanks for the 
help!
