Sinatra::DataMapper

Integrates DataMapper as a Sinatra extension; provides a some syntactic sugar around setting up repositories, models, and logging for DataMapper.

Add this line to your application's Gemfile:

gem 'sinatra-datamapper'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sinatra-datamapper

• :datamapper_log_prefix sets the prefix of any lines logged.
• :datamapper_log_level sets the logging level of DataMapper.
• :datamapper_log_path sets where log lines should be sent to.

To configure repositories, set :datamapper_repositories to a hash of which the key should be the repository name and the value can be either a hash of a URI-like string. The extension passes these to DataMapper#setup. If unset, defaults to an in-memory SQLite3 database bound to the :default repository context.

By default, the extension will automatically load any Ruby source files in the models folder of the application root. Set the :datamapper_models setting to a path containing your models, or to false to disable automatic loading.

In models/post.rb:

class Post
  incude DataMapper::Resource
  property :id,      Serial
  property :title,   String
  property :content, Text
end

In application.rb:

#!/usr/bin/env ruby

require 'sinatra'
require 'data_mapper'
require 'sinatra/datamapper'

configure do
  set :datamapper_repositories, { default: 'sqlite3://#{Dir.pwd}/database.db' }
  set :datamapper_log_level, :debug
end

get '/' do
  @posts = Post.all
  haml :posts
end
