问题 I want to save some images to a model using a dynamic cocoon form with Active Storage to handle the files. I have a farmer class that has many apples, the farmer can add multiple images for each of the different kinds of apples through the farmer form. class Farmer < ActiveRecord::Base has_many :apples, inverse_of: :farmer accepts_nested_attributes_for :apples, allow_destroy: true, reject_if: :all_blank end class Apple < ActiveRecord::Base has_many_attached :apple_images end Inside the Farmer

问题 I'm having some success with creating PDFs with PDFKit, but the images are not loading from active_storage and assets resources. It fails every single time that I create the PDF, using show.pdf.erb. I'm using the default image_tag and assets are precompiled for production. How can I get PDFKit to find the precompiled assets folder for the images, and also find active_storage images that are supposed to load within the show.pdf.erb view? It works perfectly fine in the normal show.html.erb

问题 I pushed out to heroku last night, and now today my pushes are failing with the following error. Heroku status appears to be ok. My heroku config has RAILS_MASTER_KEY set to my master.key. That did not help. Any experience this...or, able to point me towards a fix? Command: 'bin/rails runner "puts %Q{heroku_detecting_active_storage_config=#{Rails.application.config.active_storage.service}}"' failed unexpectedly: remote: ! Missing encryption key to decrypt file with. Ask your team for your

问题 I work on a system that stores cached data on S3 with ActiveStorage before using it for something else. In my spec, I want to stub the download method of this file, and load a specific file for testing purpose. allow(user.cached_data).to receive(:download) .and_return(read_json_file('sample_data.json')) ( read_json_file is a spec helper that File.read then JSON.parse a data file.) I get this error : #<ActiveStorage::Attached::One:0x00007f9304a934d8 @name="cached_data", @record=#<User id: 4,

问题 I have an Employee model with an Avatar. I can attach an image to the avatar, but whenever I try to display the image, the url_for(@employee.avatar) produces a dead link. All I'm seeing is the value from the alt attribute from the tag. The image tag I'm getting is the following <img src="/rails/active_storage/blobs/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaHBDZz09IiwiZXhwIjpudWxsLCJwdXIiOiJibG9iX2lkIn19--4786aa4d9d82d8f8d572b857965088b20fcb2f49/Portrait.jpg" alt="Thumbnail"> And I know the image has

问题 Until now I was using Paperclip for uploading some files to S3. Some of these files are not public and Paperclip allowed to upload some files as private with the following bit : has_attached_file :image, styles: { large: "2000x2000", small: "1200x1200", thumb: "250x250"}, :s3_permissions => :private Now Paperclip is deprecated I am considering switching to Active Storage though I have not found any option to make some of my files private. Is there something to tweak in Active Storage to allow

问题 Can we change the default 'permanent' url create from active storage to redirect to S3. Is something like rails/active_storage/representations/. I don't like the framework name in the url. Thanks 回答1: UPDATE : Recently, there was an addition which makes the route prefix configurable: https://github.com/rails/rails/commit/7dd9916c0d5e5d149bdde8cbeec42ca49cf3f6ca Just in master branch now, but should be integrated into ~> 5.2.2 and higher. Then, it's just a matter of configuration: Rails

问题 I've updated rails from 5.1.4 to 5.2 and remove Papaerclip to use Active Storage. I'm using digitalocean spaces. In my development env I've setted credentials in storage.yml to save images to digitalocean. I've added aws-sdk-s3 gem in gemfile (without version, may be this the problem?). I run db:migrate for active storage. But when I'm going to submit the form with an image upload html tag, i receive this error: Unable to autoload constant ActiveStorage::Blob::Analyzable. Anyone can help me?

问题 I can get url in model with this code (Active Storage) Rails.application.routes.url_helpers.rails_blob_path(picture_of_car, only_path: true) But I need get url of resized varian picture_of_car.variant(resize: "300x300").processed For example this code Rails.application.routes.url_helpers.rails_blob_path(picture_of_car.variant(resize: "300x300").processed, only_path: true) throw NoMethodError (undefined method `signed_id' for #< ActiveStorage::Variant:0x0000000004ea6498 >): 回答1: Solution:
