Rubyonrails 用于在多行上链接调用的 Ruby 约定

这是为了什么？

我使用下面的风格，但不确定它是否是首选，因为如果我在结尾处漏掉了一个点，我可能会遇到很多问题而没有意识到这一点.

query = reservations_scope.for_company(current_company).joins{property.development}.
  group{property.development.id}.
  group{property.development.name}.
  group{property.number}.
  group{created_at}.
  group{price}.
  group{reservation_path}.
  group{company_id}.
  group{user_id}.
  group{fee_paid_date}.
  group{contract_exchanged_date}.
  group{deposit_paid_date}.
  group{cancelled_date}.
  select_with_reserving_agent_name_for(current_company, [
                                       "developments.id as dev_id",
                                       "developments.name as dev_name",
                                       "properties.number as prop_number",
                                       "reservations.created_at",
                                       "reservations.price",
                                       "reservations.fee_paid_date",
                                       "reservations.contract_exchanged_date",
                                       "reservations.deposit_paid_date",
                                       "reservations.cancelled_date"
  ]).reorder("developments.name")
query.to_a # ....

那么，chaining种方法与multiple lines种方法相比有哪些约定？我应该 Select 哪一种？

NOTE:我找不到Ruby coding style guide人中的好例子.
