在Ruby中,你可以通過多種方式使方法返回值更具創(chuàng)新性。以下是一些建議:
enum Status: [:pending, :approved, :rejected]
def check_status(id)
# 根據(jù)id查詢狀態(tài)
status = Status.find(id)
status
end
def get_user_info(id)
# 根據(jù)id查詢用戶信息
user_info = {
id: id,
name: "John Doe",
email: "john.doe@example.com"
}
user_info
end
class User
attr_accessor :id, :name, :email
def initialize(id, name, email)
@id = id
@name = name
@email = email
end
end
def get_user(id)
# 根據(jù)id查詢用戶
user = User.new(id, "John Doe", "john.doe@example.com")
user
end
def get_user_and_posts(id)
# 根據(jù)id查詢用戶和文章
user = "John Doe"
posts = ["Post 1", "Post 2", "Post 3"]
[user, posts]
end
def user_posts(id)
# 根據(jù)id查詢用戶文章
posts = ["Post 1", "Post 2", "Post 3"]
posts.each do |post|
yield post
end
end
user_posts(1) do |post|
puts post
end
通過使用這些方法,你可以使你的Ruby方法返回值更具創(chuàng)新性,從而提高代碼的可讀性和可維護(hù)性。
