I have a has_many :through  companies <-> markets with emails as the
join table.

The view is relatively easy:

<% form_for :market, :html => { :id => 'marketform' } do |f|%>
        <%= hidden_field_tag "company[companyid]", @company.id, :index =>
@company.id %>
        <% for market in @markets %>
                <div>
                        <%= check_box_tag "company[market_attributes][]", 
market.id,
@company.markets.include?(market) %>
                        <%= label_tag :market_ids, market.name.upcase -%>
                        <span style="align: right;"><%= text_field_tag 
"emaildistro[#
{market.id}]" %></span>
                </div>
        <% end %>
        <input type="submit" value="Update Markets" onclick="Modalbox.show('/
markets/create', {method: 'post' ,title: 'Sending status', params:
Form.serialize('marketform') }); return false;" />
<% end %>

controller:

company = Contactcompany.find(params[:company][:companyid])
  markets = params[:company][:market_attributes] ||= []
  company.market_ids = markets
  company.emails.each{|mail|
    distro = params[:emaildistro]["#{mail.market.id}"]
    mail.update_attributes(:emaildistro => distro)
  }


Is there a way to retrieve the emails just like the checkboxes do when
you pull up the view?
