Cloudinary Intro using Ruby

Ruby install

Use a version of Ruby >= 2.4. In this repo, we are using version 2.5.7 as indicated in the ./scripts/.ruby-version file. If you are using a different version of Ruby, you can change the value in that file.

Mac

Mac comes with Ruby installed. To install the latest version of Ruby, use Homebrew:

brew install ruby

Windows

https://rubyinstaller.org/

Setup to run scripts

The scripts are run from the scripts directory.

  1. Clone this repo.

  2. Install the Cloudinary gem:

`gem install cloudinary`
  1. Set up credentials.

Create a ./scripts/config.rb file and copy the ClOUDINARY_URL value from your Cloudinary Management Console into the file as an argument for the config_from_url command. See the config.rb.sample. The code below shows two alternatives for adding credentials.

There are two ways you can make the credentials available.

# Cloudinary.config do |config|
#   config.cloud_name = "CLOUD_NAME"
#   config.api_key = "API_KEY"
#   config.api_secret = "API_SECRET"
# end
Cloudinary.config_from_url("cloudinary://API_KEY:API_SECRET@CLOUD_NAME")

Exercises

The images and videos to be used in the exercises are located in the assets directory. The scripts access assets relative to the scripts directory, so navigate to the scripts directory.

cd scripts

Running the Exercise Code

Commands are commented out in each script. You can uncomment and run script or copy and paste to run in Ruby/IRB.

  1. Uncomment commands and run ruby upload.rb to exercise storage commands.
  2. Uncomment commands and run ruby preset.rb to exercise preset commands.
  3. Uncomment commands and run ruby autoupload-fetch.rb to exercise auto-upload and fetch commands.
  4. Uncomment commands and run ruby manage.rb to exercise management commands.
  5. Uncomment commands and run ruby upload-for-transformations.rb to load assets used in transformation scripts.
  6. Uncomment commands and run ruby optimize-transformation.rb to exercise transformations that optimize.
  7. Uncomment commands and run ruby aesthetics-transform.rb to exercise transformations that enhance aesthetics.
  8. Uncomment commands and run ruby named-transformation.rb to exercise creating and using named transformations.

Using Ruby/IRB (optional)

You need version 2.4 or later of Ruby to use Ruby/IRB. This will allow you to experiment with your own commands interactively. Once you have set up the config.rb, the scripts/bin/console.rb will be able to access your credentials. From the scripts directory, run the following:

ruby bin/console.rb

Note: Commands are wrapped in JSON.pretty_generate() abbreviated as jj to make the results easier to read.

Rails Server (bonus/optional)

The directory /server is a bonus that contains code to run a Rails server.
