How do I get multiple to work nicely with Simple_Form?

[marcamillion]

So I am trying to implement multiple autocomplete and simple_form and am getting an error.

I tried this:

<%= f.input_field :neighborhood_id, collection: Neighborhood.order(:name), :url => autocomplete_neighborhood_name_searches_path, :as => :autocomplete, 'data-delimiter' => ',', :multiple => true, :class => "span8" %>

This is the error I get:

undefined method `to_i' for ["Alley Park, Madison"]:Array

In my params, it is sending this in neighborhood_id:

"search"=>{"neighborhood_id"=>["Alley Park, Madison"],

So it isn't even using the IDs for those values.

Ideas?

@marcamillion if you need the object_id you should use the id_element. Details here
