问题描述
|
class X
def initialize
@name = \"Bob\"
end
blah blah
end
puts X.new # I want this to print X:Bob
puts [X.new,X.new] # I want this to print [X:Bob,X:Bob]
解决方法
覆盖类的
to_s
方法:
class X
def initialize
@name = \"Bob\"
end
def to_s
\"X:#{@name}\"
end
end
puts X.new # prints X:Bob
puts [X.new,X.new].to_s # prints [X:Bob,X:Bob]
,您需要有initialize
,而不是init
。
