This is an application skeleton for an app using Roda as the web framework, and Sequel as the database library. It’s set up so you can clone this repository and base your application on it:
git clone https://github.com/jeremyevans/roda-sequel-stack.git mv roda-sequel-stack my_app cd my_app rake setup[MyApp]
By default roda-sequel-stack assumes a PostgreSQL database, with an application specific PostgreSQL database account. You can create this via:
createuser -U postgres my_app createdb -U postgres -O my_app my_app_production createdb -U postgres -O my_app my_app_test createdb -U postgres -O my_app my_app_development
Using an application specific, regular database user account (not a database superuser account), is recommended for security reasons.
First, you’ll want to edit the default migration file (migrate/001_tables.rb) to define the database schema for your application. After modifying the migration file, and optionally adding additional migration files, you can run the migrations:
rake dev_up # Migrate the development database up rake test_up # Migrate the test database up rake prod_up # Migrate the production database up
After editing the default migration file, you’ll probably want to rename and edit the default model file (models/model1.rb), as well as add other model files as appropriate. After the models have been set up, you can get an irb shell with your models loaded:
rake dev_irb # IRB shell with models connected to the development database rake test_irb # IRB shell with models connected to the test database rake prod_irb # IRB shell with models connected to the production database
After editing the model files, you’ll probably want to edit the application file (app.rb). You’ll also want to rename and edit the default routing subtree (routes/prefix1.rb). After that, you’ll probably want to edit the layout (views/layout.erb) and index page (views/index.erb), as well as add any other views.
After making those changes, you can start your application using rackup or similar program.
