如何将字符串对象转换为数组？

在我的代码中，我可以接收一个数组。
示例：

Eq = ["5f17283521ac387fc8eeca6a", "5f17283c21ac387fc8eecb78", "5f17285621ac387fc8eed109", "5f17286321ac387fc8eed3ca", "5f17286621ac387fc8eed433", "5f17286d21ac387fc8eed5c8", "5f17287221ac387fc8eed6c7", "5f17288621ac387fc8eeda69", "5f17288921ac387fc8eedb1d", "5f17289421ac387fc8eedd39", "5f17289521ac387fc8eedd93", "5f17289821ac387fc8eeddfc", "5f17296e21ac387fc8ef0a57"]

而且我也可以简单地收到一个标识字符串。
示例：

Eq = "5f17296e21ac387fc8ef0a57"

如何将这个字符串转换成数组？

consulta_OS.each do |os|
  if os.equipment.map(&:to_s) != []
    eq_id = os.equipment_ids.map(&:to_s) #equipment_ids receive in array  else
    eq_id = os.equipment_id.to_s #equipment_id in string
  end
end

Answer 1

你可以这样做：

EQ = ["5f17296e21ac387fc8ef0a57"]

或者您的情况：

EQ = [os.equipment_id.to_s]
