ruby-on-rails - 编写具有重复值的 Ruby Hash 而不重复值

Question

我在 Rails Controller 中有以下代码:

@users = User.where(["first_name = :first_name or
                    last_name = :last_name or
                    company = :company",
                    { first_name: term, last_name: term,
                    company: term }])

术语是 term = params[:search]

我不喜欢我重复 term

{ first_name: term, last_name: term,
                        company: term }

是否有一种 DRYER 方法可以做到这一点？

谢谢!

你可以这样做:

@users = User.where("first_name = :term OR
  last_name = :term OR company = :term", term: term)
