`create_notice’

The code is:

–Notice Model
class Notice < ActiveRecord::Base
has_many :graphics
end

–Project Controller
def create_notice
@notice = Notice.create(params[:notice])
end

–Form
<%= form.file_field(:graphic) %>

–Graphic
class Graphic < ActiveRecord::Base
belongs_to :notice
attr_accessor :notice_id
has_attached_file :graphic,
:storage => :s3,
:s3_credentials => RAILS_ROOT + “/config/s3.yml”,
:path => “:attachment/:id/:style.:extension”,
:bucket => “attachements”
end

Thanks!
