ActiveRecord::StatementInvalid in Site#create

So I was getting the following error in my Ruby on Rails application.
Mysql::Error: Column 'added' cannot be null: INSERT INTO mytable (`added`, `highlight`, `modified`, `title`, `tags`, `tag_id`, `username`, `border`, `paid`, `desc`, `site_type`, `link`, `usersubmitted`) VALUES(NULL, '0', NULL, 'testing', '', 1, '', '0', '0', ' testing', '', 'testing', '0')

As is obvious, the column 'added' cannot be null. We can fix this by overriding the method create (this is the method where the "new" form is submitted to )

def create
@site = Site.new(@params['site'])
#we were getting "added cannot be null"
@site.added = Date.today
@site.modified = Date.today
if @site.save
redirect_to :action => 'list'
else
render_action 'new'
end
end



Add the delete link


<%= link_to "(delete)",
{:action => "delete", :id => site.id},
:confirm => "Really delete #{site.title}?" %>
