Grantfile example

user "scott", "%" do
  on "*.*" do
    grant "USAGE"
  end

  on "test.*", expired: '2014/10/08', identified: "PASSWORD '*ABCDEF'" do
    grant "SELECT"
    grant "INSERT"
  end

  on /^foo\.prefix_/ do
    grant "SELECT"
    grant "INSERT"
  end
end

user "scott", ["localhost", "192.168.%"], expired: '2014/10/10' do
  on "*.*", with: 'GRANT OPTION' do
    grant "ALL PRIVILEGES"
  end
end

Use template

template 'all db template' do
  on '*.*' do
    grant 'SELECT'
  end
end

template 'test db template' do
  grant context.default

  context.extra.each do |priv|
    grant priv
  end
end

user 'scott', 'localhost', identified: 'tiger' do
  include_template 'all db template'

  on 'test.*' do
    context.default = 'SELECT'
    include_template 'test db template', extra: ['INSERT', 'UPDATE']
  end
end
