Mongoid::Shell

Create mongo command-lines from Mongoid configuration.

For example, connect to your production database without having to remember the entire command line using a db:production:shell Rake task.

namespace :db
  namespace :production
    task :shell
      Mongoid.load! File.join(Rails.root, "config/mongoid.yml"), :production
      system Mongoid::Shell::Commands::Mongo.new.to_s
    end
  end
end

Commands can be created for the current default session or you can pass a session as an argument to a new command.

Mongoid::Shell::Commands::Mongodump.new # will use Mongoid.default_session
Mongoid::Shell::Commands::Mongodump.new(session: Moped::Session.new([ "127.0.0.1:27017" ]))

Commands accept parameters.

out = File.join(Dir.tmpdir, 'db_backup')
mongodump = Mongoid::Shell::Commands::Mongodump.new(db: 'another_database', out: out)
system mongodump.to_s # mongodump --db another_database --out /tmp/db_backup

Compatibility

This gem supports Mongoid 3, 4 and 5.
