I want to trimming the image of paperclip in my database. Because I`m running my own private web service, but I forgot to add the styles when user create the image...
has_attached_file :avatar,
:storage => :s3,
:styles => { # I forgot to add this styles
:medium => "370x370#", # I forgot to add this styles
:thumbs => "120x120#" # I forgot to add this styles
}
So I want to run the rake task and trimming like 370×370# and 120×120#. But I cant`t find the way to trimming the image after user save.
Does anyone assist me ?
The paperclip gem comes with a rake task for exactly this purpose:
rake paperclip:refresh:thumbnails
Just run that from the command line and it will take care of generating all of your reduced-size images.
