When I copy a paperclip attachment it applies the default cropping defined in the style and ignores the cropper I have installed for cropping on the site via user input (CropperJs). What I need is just a raw copy of the image as it was cropped on the source image. I solve this by bluntly copying the file right now, but is there a better way?
has_attached_file :avatar,
:name => 'avatar',
:styles => {
:cropped => {
:geometry => "55x55#",
:processors => [:cropper]
},
:large => "600x600>"
}

I'm new to Rails and using Paperclip, I have it set up on my model already without issue. I just don't like the path it's generating for my images right now (:root_path/system/users/avatars/000/000/001) I really don't even understand it. How can I modify this default path for my images to something more friendly? And how can I hash the image names?
In your model, you can set the default path, styles and url as so:
has_attached_file :avatar,
:styles => { :large => "500x500>", :medium => "300x300>", :thumb => "100x100>" },
:path => ":rails_root/public/images/:id/:style/:filename",
:url => "/images/:id/:style/:filename"
you can setup the hash on the paperclip initializer file (config/initializers/paperclip_defaults.rb)
Quoting from paperclip wiki:
Paperclip::Attachment.default_options.update({
:path => ":class/:attachment/:hash/:style.:extension",
:hash_secret => "SOME_RANDOM_SECRET"
})
The :hash part is generated from :hash_secret and the pattern given by the :hash_data option, which by default is ":class/:attachment/:id/:style/:updated_at".
I am using Paperclip with Rails4. I have the following image
Now i want to resize and Crop the image but its getting cropped and orientation of the image is getting displaced like below
:photo,
:path => ":rails_root/public/system/:attachment/:id/:style/:filename",
:url => "/system/:attachment/:id/:style/:filename",
:styles => {
:small => { :geometry => "100x100!" },
:medium => { :geometry => "500x500!"}
}
Check out ImageMagic resize docs. You probably need to use 100x100# instead of 100x100!
I'm using paperclip gem for uploading and resizing images. This setup works fine. I'm able to display the uploaded images. The problem comes when I try to resize the uploaded image.
Here is snippet from the model file
has_attached_file :photo,
:size => {:small => "150x150>"}
When I try to upload the image I get this error.
Photo /var/folders/gm/gm-SegRMHuOkSlYtTMkO8U+++TI/-Tmp-/file.jpg is not recognized by the 'identify' command.
I'm sure that the file is jpg. Here is the output of the file command
file.jpg: JPEG image data, JFIF standard 1.01, comment: "CREATOR: gd-jpeg v1.0 (using IJ"
I'm not sure but in our application we do the same thing and it works. Our code looks like this:
has_attached_file :image,
:styles => {:small => "280x173#", :medium => "635x393#"},
:convert_options => {:all => "-quality 80"},#,
:default_style => :medium,
:default_url => "/images/study/nophoto.jpg"
validates_attachment_size :image, :less_than => 10.megabyte
validates_attachment_content_type :image, :content_type => ['image/gif', 'image/png', 'image/x-png', 'image/jpeg', 'image/pjpeg', 'image/jpg']
The difference I see, is that you might have to provide convert_options to be able to resize.
Have you tried any other jpg file, maybe with a simpler path also?
I am using Paperclip for uploading the Profile image in my application (rails)
My User model is having a
has_attached_file :avatar,
:url => "/:attachment/:id/:style/:basename.:extension",
:path => ":rails_root/public/:attachment/:id/:style/:basename.:extension",
:styles => { :medium => "300x300>", :small => "100x100>", :thumb => "50x50>", :micro => "30x30>" }
In my VIew If i have a profile image uploaded then its pointing correctly as
/avatars/1/thumb/iamge
BUt if the image is not there if they didn't uploaded in that case its pointing as
/avatars/thumb/missing.png which doesn't have any image.
Please give suggestions what to do if the user didnt uploaded any profile image..
You can make a default image and put it there and name it missing.png. It is like extra functionality :)
class User < ActiveRecord::Base
has_attached_file :photo, :styles => { :square => "100%", :large => "100%" },
:convert_options => {
:square => "-auto-orient -geometry 70X70#",
:large => "-auto-orient -geometry X300" },
:storage => :s3,
:s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
:path => ":attachment/:id/:style.:extension",
:bucket => 'mybucket'
validates_attachment_size :photo,
:less_than => 5.megabyte
end
Works great on local machine, but gives me an error on Heroku: There was an error processing the thumbnail for stream.20143
The thing is I want to auto-orient photos before resizing, so they resized properly.
The only working variant now(thanks to jonnii) is resizing without auto-orient:
...
as_attached_file :photo, :styles => { :square => "70X70#", :large => "X300" },
:storage => :s3,
:s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
:path => ":attachment/:id/:style.:extension",
:bucket => 'mybucket'
...
How to pass additional convert options to paperclip on Heroku?
UPD
I discover, the trouble in "-auto-orient" option. It seems like this option is broken in version of ImageMagick used by Heroku. I created custom paperclip image processor inherited from paperclip's standard thumbnail:
module Paperclip
class Ao < Thumbnail
def transformation_command
super + " -auto-orient"
end
end
end
It works perfect on local machine, but fails on Heroku.
These are the sizes I use. They all work fine on heroku:
SIZES = {
:original => "640x480>",
:thumb => "150x150#",
:mini => "60x60#",
:micro => "30x30#"
}
Make sure your gem version of paperclip is the same as heroku's. You can specify the specific gem version in your .gems file and in your environment.rb to make sure they line up.
I'm not sure exactly why your convert_options are causing problems, but if I remember correctly paperclip uses ImageScience directly and your chosen options might be incompatible with the read only heroku file system.
If this is critical and you need an answer right now I'd raise a support ticket on heroku. If you get a response make sure you post it back here!
