Rails - Dec 2005 - checkboxes

Hi,

I''ve got a form like so:

<% @companies.each do |company| %>
<%= company.name %>
<input type="checkbox" name="companies[]"
value="<%= company.id %>" /><br/>
<% end %>

which posts eg. this hash:
 *Parameters*: {"commit"=>"Dispatch",
"companies"=>["36", "29", "31",
"34"]}

to this action:

def dispatch
  if params[:companies]
    params[:companies].each do |key, value|
      @company = Company.find(value)
      @companies << @company
    end
end

I get the error message "Couldn''t find Company without an ID"

help!

Thanks in advance

Adam

I think params[:companies] is an Array, not a Hash, so .each won''t pass
you the key, just the value.  So you need something like:

params[:companies].each do |value|

Hope this helps
