Rails Active Storage

This guide will show you how to connect ActiveStorage in Rails 7 to Storj (an AWS S3 compatible object storage). You can also look at the source code of this example. We have a webinar walking you through it, but you can also refer to the steps below:

Prerequisites:

• Installed ruby 3.1.2 or later
• Installed rails 7.0.4.2 or later
• Storj S3 compatiable access and secret key (see AWS SDK and Hosted Gateway MT)
• A bucket created on Storj (see Create a Bucket)

Configure ActiveStorage to Storj

Create a new rails app

Install ActiveStorage

Edit Gemfile, add the aws-sdk-s3 gem and run bundle install

Edit the rails credentials

Add to the credentials your access key and secret key (see AWS SDK and Hosted Gateway MT) under storj:

Edit config/storage.yml, enter the following to configure ActiveStorage to use Storj. Be sure to replace the bucket with the one created earlier (see Create a Bucket)

Edit config/environments/development.rb, change the ActiveStorage service to :storj

Use active storage images hosted by Storj

First we'll need a basic app to interact with generated with Rails scaffolding

Edit config/routes.rb set root to "names#index

Edit app/models/name.rb to have has_one_attached

Edit app/views/names/_form.html.erb to include a field_field to allow the user to choose a file to upload

Navigate to http://localhost:3000/names/new and you should see the following



Click "Create Name" Edit app/views/names/show.html.erb to include <%= image_tag @name.main_image %> to display the image

Edit app/assets/stylesheets/application.css to style the image to fix the size of the screen

Navigate to http://localhost:3000/names/1 to see your image

Enable direct to Storj upload

Edit config/importmap.rb to include the @rails/activestorage package

Edit app/javascript/controllers/application.js to initialize the ActiveStorage

Modify app/views/names/_form.html.erb form.file_field to include direct_upload: true
