Question

In my rails form i am using a multi select tag

code looks like

  <%= select_tag '[mycontroller][users]', @users, { :multiple => true, :size => 7} %>
  <p><%= submit_tag l(:button_apply)%></p>

On form submit parameters passed are

 mycontroller[users][]=79&mycontroller[users][]=80&commit=Apply

Now in my view file when i retrieve params they are being converted to string
so i get [79,80] being converted to “7980”

code for getting user param looks like

users =  params[:mycontroller][:users] unless params[:mycontroller].nil? 

Edit:

Problem i suppose is that “#{}” converts array to string. even <%= %> will call to_s

So how to override this? So that to_s will return “79,80” instead of “7980”

What am i missing?
Comments, please?

Thnx.

Answer 1

Try to call array.join(“,”) and a array of [79,80] should become a string like “79,89”
