I have a form in my Rails application, and in the form, there is a textbox that corresponds to :mylist, which is an attribute of my class Catcher's object @mycatcherobject In the form, people will paste something that looks like this:
我在我的Rails应用程序中有一个表单，在表单中，有一个对应于：mylist的文本框，它是我的类的属性Catcher的对象@mycatcherobject在表单中，人们将粘贴如下所示的内容：

After the form is submitted, I need to turn what was pasted into that text box (that is, what is now the value of :mylist) into an array. For the above example, there would be three elements in the array (one for each of the items above).
提交表单后，我需要将粘贴到该文本框中的内容（即，现在的值：mylist）转换为数组。对于上面的示例，数组中将有三个元素（上面的每个项目都有一个元素）。
Do you have any idea how to do this? I can't figure out how to convert an object's attribute's value into an array anywhere.
你知道怎么做吗？我无法弄清楚如何将对象的属性值转换为数组。
I've tried things like %w(#{@mycatcherobject.mylist}), but that doesn't work.
我尝试了％w（＃{@ mycatcherobject.mylist}）之类的东西，但这不起作用。
I'm fairly new at Rails, so my apologies if this seems obvious. Your help would be greatly appreciated.
我在Rails上相当新，所以如果这看起来很明显，我很抱歉。非常感谢您的帮助。

That comes in the controller as a param[:name of the field] and you can write a regular expression to split the string. In case the elements are separated by a comma or a special character you can do something like
它在控制器中作为参数[：字段的名称]，您可以编写正则表达式来拆分字符串。如果元素由逗号或特殊字符分隔，您可以执行类似的操作
result = params[:list].split(",")
