有没有什么方法可以在ruby中将布尔变量转换为整数

问题描述：

我有一个 ruby 变量is_published".我想将is_published"中的值转换为整数.ruby 中是否有任何方法可以做到这一点?

I have a ruby variable 'is_published'. I want to convert the value in 'is_published' to integer. Is there any method in ruby to do that?

if is_published == true
  is_published = 1
else
  is_published = 0
end

以上代码完美运行.如果有任何方法可以在单行代码中执行此操作，请提供帮助.

The above code works perfectly. Please help if there is any way to do this in a single line code.

class TrueClass; def to_i; 1; end; end
class FalseClass; def to_i; 0; end; end
