Store thumb image to specific directory in paperclip gem

Question

Here is the code

  has_attached_file :image,
                        :path => ":rails_root/public/images/:id/:filename",
                        :url  => "/images/:id/:filename",
                        :styles => { :small => "300x168>", :large => "1000x560>" }

Here is my console log

I need to store small,large and original image to my project public directory but it store only the original

Answer 1

Check that your image magick installed correctly or not as resizing is depends on image magick.

to refresh all of your defined styles in one go (:thumb, :small, :medium from the above example)

rake paperclip:refresh CLASS=Modelname

and to refresh only missing styles: a list of styles will be defined or updated in a file “/public/system/paperclip_attachments.yml”

rake paperclip:refresh:missing_styles

Additionally, if you want to only reprocess a single style you may do so like:

users_to_reprocess.each do |user|
  user.image.reprocess! :small
end

Answer 2

You can use :styles of paperclip gem in your model. Like,

has_attached_file :photo,
  :styles => {
    :thumb=> "100x100#",
    :small  => "150x150>",
    :medium => "300x300>",
    :large =>   "400x400>" }

And your photo url is going to be as follows : /public/photos/(event#)/(size_name)/image_name

And you have to install ImageMagick and rb-magick ports to get this going.
