我有一个名为Family Members的类（在文件family_members.rb中），其中包含name，sex，type，{{等属性1}}和role
在这个类中，我定义了一个名为age的方法，它检查parent?类的实例是否为Family members type
代码工作正常，但我想知道是否可以在另一个类中定义parent方法（可能是parent?或者只能包含该类），因为这样做使代码更整洁。
有效的代码（但我想改进）：
superclass我尝试在另一个名为#family_members.rb
class FamilyMembers
attr_accessor :name, :sex, :status, :age
def initialize (name, sex, type, role, age)
@name = name
@sex = sex
@type = type
@role = role
@age = age
end
# Would Like the ability to put this method in another file or class
def parent?
parent_or_child = @type
role = @role
age = @age
name = @name
if parent_or_child == 'Parent'
then puts "Yes, this family member is a parent; more specifically, a #{role} named #{name} who is #{age} years old."
else puts "This family member is not a parent, it`s only a child; more specifically, a #{role} named #{name} who is #{age} years old."
end
end
end
fm1 = FamilyMembers.new('John','Male', 'Child', "Son" , "27" )
fm2 = FamilyMembers.new("Bill","Male", "Parent", "Father" , "63" )
fm1.parent?
的文件中定义该方法，并使用ParentOrChild.rb将其包含在family_members.rb的顶部。但是当我这样做时，错误消息告诉我它无法加载这样的文件..
require_relative我还试图在另一个类中定义该方法（在文件#ParentOrChild.rb
def parent?
parent_or_child = @type
role = @role
age = @age
name = @name
if parent_or_child == 'Parent'
then puts "Yes, this family member is a parent; more specifically, a #{role} named #{name} who is #{age} years old."
else puts "This family member is not a parent, it`s only a child; more specifically, a #{role} named #{name} who is #{age} years old."
end
end
中：
parent_or_child.rb但是当我执行上述操作时，错误告诉我存在未定义的方法#parent_or_child.rb
class ParentOrChild
def parent?
parent_or_child = @type
role = @role
age = @age
name = @name
if parent_or_child == 'Parent'
then puts "Yes, this family member is a parent; more specifically, a #{role} named #{name} who is #{age} years old."
else puts "This family member is not a parent, it`s only a child; more specifically, a #{role} named #{name} who is #{age} years old."
end
end
end
（指parent?文件。
我使用的是Ruby 2.0，所以我认为使用family_members.rb而不是require_relative是正确的。
关于如何做到这一点的任何建议都会很棒 - 谢谢。
答案 0 :(得分：1)
这最初是一个评论，但它也是解决方案，所以我将其添加为答案。
听起来你需要研究继承（或子类）。基本上是：
class ParentOrChild < FamilyMembers
这样，子类ParentOrChild将继承父类FamilyMembers
的方法作为旁注，以问号结尾的方法应该只返回true或false。
