Ruby on Rails从文本区域中的列表中保存多个子记录

Question

I have scoured stack overflow for and answer to my problem but can't find one. So I was hoping that someone else out there has tried what I want to do before.

I have a question model, which has many options. What I want to do is allow the user to copy a list of options into a textarea as a return/new line separated list.

ie a list of locations

London
Paris
New York
Singapore
Sydney

And then from the questions controller I want to get each of these items insert them in the options model.

What I can't work out is how I access the textarea element from the controller as there is no object name associated with it.

Any help would be greatly appreciated.

Thanks Ben

One way to go about it is associate the textarea element with your 'options' attribute, and then write a function in your model to split it into an array.

For example, in your view:

<%= form_for @question do |f| %>
...
<%= f.text_field :options %>

Then in your controller:

def create
  @question = Question.new(params[:question])

  ...
  @question.split_options

  ...
end

In the model, the split_options method could use Ruby's string split functions to return an array, which then gets saved.
