Models

Pliny models are just like Rails', only using Sequel::Model instead of ActiveRecord. Use them to wrap access to database.

You should try keep models lean. Think of them as pure data objects: every single method in a model should only return data that came from the database or was generated from another static source. They should not manipulate data, interact with other models, make API requests, etc – Mediators are a much better fit for these.

To get a new model:

$ pliny-generate model todo
created model file ./lib/models/todo.rb
created migration ./db/migrate/1408995997_create_todos.rb
created test ./spec/models/todo_spec.rb

Then edit the migration to add any additional fields you might need beyond the id and timestamps:

Sequel.migration do
  change do
    create_table(:todos) do
      uuid         :id, default: Sequel.function(:uuid_generate_v4), primary_key: true
      timestamptz  :created_at, default: Sequel.function(:now), null: false
      timestamptz  :updated_at, default: Sequel.function(:now), null: false
    end
  end
end
