paperclip

问题 I recently installed the paperclip-optimizer gem in my Rails 4 app on Heroku. Whenever I attempt to save an uploaded image attachment, I get the following error: jpegrecompress worker: 'jpeg-recompress' not found; in my logs from Heroku, but not on localhost. I'm not sure what I'm missing. I can't seem to find a single StackOverflow post, blog post, or other resource on this problem. Here is my config/initializers/paperclip_optimizer.rb : Paperclip::PaperclipOptimizer.default_options = { skip

问题 I am using the paperclip and paperclip-av-transcoder in my rails app and I have gotten to the point where I can upload videos locally. But when I try it in heroku I get this error. Av::UnableToDetect (Unable to detect any supported library): I may have to add something to make it work with s3 but I had it working with images earlier so everything should be setup for s3. This is the code in my model class Classvideo < ActiveRecord::Base belongs_to :user has_attached_file :video, :styles => {

问题 Using Paperclip Gem in a Rails 4 project to attach an image and then clean out all exif data, like this: has_attached_file :image, styles: lambda{ |a| { large: ['800x', :png], thumb_340: ['340x340#', :png], thumb_180: ['180x180#', :png] } }, convert_options: { all: '-strip' } Problem is, convert_options isn't getting called on the original image. What's the best method for reprocessing (or pre-processing) the original to make sure that '-strip' gets called? 回答1: try this has_attached_file

问题 I have an object with several associations. Some of these associated objects have paperclip-attachments stored at S3. If I duplicate the object and the associations it works fine but the attachments are not duplicated. This here works without getting the images: copy_salon = @salon.dup copy_salon.about_us_versions = @salon.about_us_versions.collect{|about_us| about_us.dup} I tried to get the image link like this: copy_salon = @salon.dup copy_salon.about_us_versions = @salon.about_us_versions

问题 I have a RoR app with image upload through paperclip and amazon s3. Everything was working fine until I decided to change the routes from myapp.com/id to myapp.com/model-name. Now I get the following error: LoadError cannot load such file -- aws-sdk (You may need to install the aws-sdk gem) . These changes involved changing the model, the controller, and the db. Model: class Major < ActiveRecord::Base attr_accessible :glance, :name, :image # Validations validates :glance, presence: true

问题 In rails 4.0.2, I am using paperclip gem to upload files. But it is not supporting .doc file. Below the file upload field, it is showing an error message as "has an extension that does not match its contents" In model, the validation for checking the content type is given below : validates_attachment_content_type :document, :content_type => ['application/txt', 'text/plain', 'application/pdf', 'application/msword', 'application/vnd.openxmlformats-officedocument.wordprocessingml.document',

问题 I can't seem to find an example that is complete in all the components. I am having a hard time deleting image attachments Classes class Product has_many :product_images, :dependent => :destroy accepts_nested_attributes_for :product_images end class ProductImage belongs_to :product has_attached_file :image #(etc) end View <%= semantic_form_for [:admin, @product], :html => {:multipart => true} do |f| %> <%= f.inputs "Images" do %> <%= f.semantic_fields_for :product_images do |product_image| %>

问题 I am using Ruby on Rails 3 on a MacOs running 'Snow Leopard' v1.6.5. I want to use the 'paperclip' gem so I included it in my Gemfile like this: gem 'paperclip', "~> 2.3" Then, in the Terminal I run the command: sudo bundle install The result is: ... Using paperclip (2.3.8) Using thor (0.14.6) Using railties (3.0.1) ... Your bundle is complete!

问题 I have a rails 3.2 app with paperclip 3.2 and I have a model that has a required paperclip attachment(thumb). How can I create valid objects without having the file saved to the filesystem or S3. What I currently have is below but this saves to the filesystem on each run. Is there a way to have a valid episode without uploading everytime? Model: class Episode include Mongoid::Document include Mongoid::Paperclip has_mongoid_attached_file :thumb validates_attachment_presence :thumb end Spec:
