Question

I m getting a response in the format of

 #<Response:0x000...   @first = "Charlie", @last=Kelly, ....

并且我需要把这变成一个 has(积极的商人)。目前,我正在经历各种变量,并这样做:

response.instance_variables.each do |r|
  my_hash.merge!(r.to_s.delete("@").intern => response.instance_eval(r.to_s.delete("@"))) 
end

This works, it will produce {:first = "charlie", :last => "kelly"} , but it seems a bit hacky and unstable. Is there a better way to do this ?

edit:我刚刚认识到,我可以在这个方程式的第二部分使用“可变的”植被,但这仍然留下主要问题。

铁路有<代码>的方法仅此点,目标称为instance_ Values。这里有在Kouate 。

class C
  def initialize(x, y)
    @x, @y = x, y
  end
end

C.new(0, 1).instance_values # => {"x" => 0, "y" => 1}
C.new(0, 1).instance_values.symbolize_keys # => {:x => 0, :y => 1}
