+# Ruby on Rails - Eco Benchmark
+
+## Context
+
+https://github.com/Boavizta/ecobenchmark-applicationweb-backend
+
+## Application
+
+### Generation
+
+```
+rails new ecobenchmark \
+  --api \
+  --database=postgresql \
+  --skip-action-mailer \
+  --skip-action-mailbox \
+  --skip-action-text \
+  --skip-active-job \
+  --skip-active-storage \
+  --skip-action-cable \
+  --skip-asset-pipeline \
+  --skip-javascript \
+  --skip-hotwire \
+  --skip-test \
+  --skip-system-test
+```
+
+### Specifities
+
+#### Creation timestamp
+
+To use `creation_date` as the creation timestamp instead of the Rails-default `created_at`, we set an alias in `app/models/application_record.rb`
+
+```rb
+class ApplicationRecord < ActiveRecord::Base
+  # ...
+
+  alias_attribute :created_at, :creation_date
+end
+```
+
+#### Initial schema
+
+Because database tables are already defined, we create the database schema with a database migration file present in the `db/migrations` folder.
+
+The `if_not_exists` prevent the application to override the existing database.
+
+#### Docker-Composer hostname
+
+On the Docker-Compose network, the app is named "service", so the runner will make requests to "http://service:8080".
+
+By default, Rails blocks unknown hosts, so we need to add it to the configuration, in `config/environments/development.rb`.
+
+#### SQL requests implementation
+
+To respect the contribution guidelines, we use custom classes (in `app/lib` folder) to generate the responses for the GET requests.
+
+As for the POST requests, the SQL requests generated by the ORM are pretty much the same, the only minor difference is that the `id` attribute is not present in the INSERT INTO as an input, but as the output of the request.
+
+Thus, the request `INSERT INTO account(id, login, creation_date) values ($1, $2, $3)` becomes `INSERT INTO account(login, creation_date) values ($2, $3) RETURNING id`.
