Plain ruby code application with Rails taste

We usually have to create plain ruby code a database dependency. This code is an starting point for this.

The magic in this repo consists in:

• You configure your database in a config/database.yml file like when you are on Rails.
• You add your migrations in the folder db/migrate/ like when you are on Rails.
• You can add your seeds in the file db/seeds.rb like when you are on Rails
• It includes the power of database Rake tasks for ActiveRecord library so you can run rake db:migrate and an automatic schema.rb file will be created.

BUT you will be using just PLAIN ruby code!

Also, a Microservice starting point

Furthermore, whether you need to create an API, you can use this repo as an starting point.

In fact, the demo prepared in this repo consists in a web microservice including a sinatra endpoint which will respond with data persisted in the database.

Follow next steps to start the web microservice.

Instalation

docker-compose build
docker-compose run app rake db:create db:migrate
docker-compose run app rake db:seed

Run demo

Follow the instalation steps and then:

docker-compose up

Open a web browser and visit http://localhost:8888/

You will receive a JSON response with the data created throw the db/seeds.rb file.

Take a look at the available rake tasks

docker-compose run web rake -T

How to add a new migration

Just create a migration file in 'db/migrate' folder, using numerical order at the beginning of the file. E.g., take a look a the already existent file 001_create_table_pets.rb

Run migrations

docker-compose run web rake db:create db:migrate db:seed
