and rmagick
sudo gem install rmagick (or image science) they are the libraries
that do the resizing.
in your model, you want:
has_attachment :content_type => :image,
:storage => :file_system,
:max_size => 500.megabytes,
:path_prefix => File.join(''public'',
''assets'', ''''),
:resize_to => ''440x594'',
:thumbnails => { :thumb => [150, 203], :small => [65,
88] }
validates_as_attachment
then in your views you can do;
@modelname.public_filename
and returns where the image is stored (which by default is not public/
images but public/assets) but it doesnt matter because its all behind
the scenes for you.
hope it helps
