I would like to add dynamically new input (select) field, this is ok and done by JQuery, but when passing to the controller create it keeps only the first entry.

This is my new.html.erb view

<%= simple_form_for @comp, :url => url_for(:controller => 'competitors', :action => 'create'), :method => 'post' do |f| %>
    <div id="form_inputs">
        <%= f.error_notification %>
        <br />
        <%= f.collection_select :user_id, User.order("LOWER(name) ASC"), :id, :name, :prompt => "Select an user", required: true %>
        <span class="label label-important"><%= f.error :user_id %></span>
        <br />
        <%= f.collection_select :competitor_id, Company.order("LOWER(name) ASC"), :fb_id, :name, :prompt => "Select a competitor"%>
        <span class="label label-important"><%= f.error :competitor_id %></span>
        <br />
    </div>
        <div class="add">Add another competitor <%= image_tag "add.png" %></div>
        <br />

    <%= f.button :submit, "Create new competitor!" %>

<script type="text/javascript">

    $(".add").on('click', function(event){
        event.preventDefault();

        $("#form_inputs").append("<%= escape_javascript(f.collection_select :competitor_id, Company.order('LOWER(name) ASC'), :fb_id, :name, :prompt => 'Select a competitor') %> <span class='label label-important'><%= escape_javascript(f.error :competitor_id) %></span><br /> ");

        $('select').selectpicker();
    });

</script>

<% end %>

The params that I would like to recieve in my controller is something like this:

params[:user_id] => OK
params[:competitor_id] => an array of all IDs that the user has inserted (can be only 1 or +).

For example, if the user "clicks" three times the add buttons, there are 4 competitor_id and the params[:competitor_id] should be something like:
params[:competitor_id] = [71,32,65,234] in the order of selects.

How can I convert the various :competitor_id selects in one array?

  • I'd suggest `competitor_ids` instead. See this related question: http://stackoverflow.com/questions/5054633/rails-3-has-many-through-form-with-checkboxes – Damien Roche Apr 24 '13 at 12:38
  • @damoiser what is that you can do with `multiple => true` options something like this `<%= f.collection_select :competitor_id, Company.order("LOWER(name) ASC"), :fb_id, :name,:multiple => true%>` – Viren Apr 24 '13 at 17:47
  • thanks both for the suggestion, I'd try the @Zenph suggestion but with no success (seems that I can't do a "pluralize" and again the model of competitor is simples an association 1-1 to an user and a competitor); then I'd try with :multiple as Viren suggests, but nothing changes (tried different combination but not renders any multiple attribute in html) – damoiser Apr 25 '13 at 09:08
  • @damoiser what happen to ur html code after u did `multiple => true` because the way I knew it would give you a tag with name like this `competitor_id[]` resulting in passing multiple selected value in the as only select box that is render – Viren Apr 25 '13 at 10:33
  • @Viren nothing happens, that's the problem. I have read, like you say, that a tag name like competitor_id[] must be showed, but it's not my case (maybe because I use selectpicker from bootstrap? That rewrite partially the select input code). – damoiser Apr 25 '13 at 11:39
  • @damoiser I dont feel that way that a js plugin would change the behavior of the collection_select did u blindly copied my code because I just give you a prespective I wasnt sure abt the correct syntax – Viren Apr 25 '13 at 14:45
