初学ruby 怎么把一个类导入呢

1. 例如在

Person.rb 中 
Python code:

class Person
def talk
puts "nihao"
end

end




Student.rb
Python code:

class Student < Person
def talk
puts "nihao"
end

end


p = Student.new

p.talk




结果
>ruby Student.rb
Student.rb:1: uninitialized constant Person (NameError)
>Exit code: 1

自己添加require上去就行了～～～不过发现csdn ruby on rails 貌似人不多阿～～

不用那么麻烦的，在ruby中，include就可以实现继承
Python code:

class Student
include Person
def talk
puts "nihao"
end

end
