I am developing a small app in Rails 3.
On one page I am gathering IDs for each user (in a each loop) in an array. Then I am putting the content of that array in a hidden text field and send it in to a method called "add\_all". In this method I got a loop that is supposed to pick each users id and add it to the database one by one but it only adds the first one.

In the view (a bit simplyfied):

```
<% profileids = Array.new %>
<% @notfriends.each do |contact| %>
<% profileids << contact.id %>
<% end %>

<%= hidden_field_tag :profileids, profileids.join(",") %>

```

In the controller:

```
params[:profileids].each do |id|

@profile = Profile.find(params[:profile_id])

@contact = Contact.create(:profile_id => params[:profile_id], :friend_id => id)

@profile.contacts << @contact

end

```

Am I really doing this right? Why is the controller each not looping through the array?
