class Hash

    [self.keys.map{|k| "#{k} = ?" }.join(" AND "), self.values].flatten

  end

end



test "convert hash conditions to array conditions" do

  assert_equal ['city = ? AND country_code = ? AND state = ?',

    "Adendorf", "DE", "Niedersachsen"], {

      :country_code => "DE",

      :state => "Niedersachsen",

      :city => "Adendorf"

    }.to_array_conditions
