Hello All,
I have been working on dynamically filling the drop box some more and got it to
work -- if I call the model directly from the view (code snippet below <%=
select("wsc_uid"...)...).
Now, I know this is not correct. I resorted to doing it this way because when
trying to pass category['wsc_uid_pk'] to the controller, via a param, a nil
value is being passed - even though I can clearly see there is data for
category['wsc_uid_pk'].
I tried Andrew's suggestion for hidden field tag but to no avail... the
controller was still not seeing the data.
Can anyone please give me an idea of what I need to do to get this to work
correctly between View - Controller - Model?
Code Snippet from View:
-----------------------
<% @list_web_serv_cats.each do |category| %>
<tr><td height="25px" align="left" valign="top" > <%=
category['wsc_description'] %></td>
<!-- added back below check box for html cleanup -->
<td height="25px" align="left" valign="top" style="display: inline;" ></td>
<!-- service category types -->
<!-- insert code here to dynamically fill the drop box from database based on
category primary key -->
<td height="25px" align="left" valign="top" style="display: inline;" >
<!-- this works but it is not correct. i should be passing
category['wsc_uid_pk'] to controller and using controller to call model... -->
<%= select("wsc_uid"+category['wsc_uid_pk'].to_s, "id",
Customer.list_web_serv_types(category['wsc_uid_pk']).map {|u|
[u['wbt_description'], u['wbt_uid_pk']]}) %>
<!-- this works but it is not correct. i should be passing
category['wsc_uid_pk'] to controller and using controller to call model... -->
</td>
</tr>
<!-- next column: service category subtypes -->
<% end %>
Code Snippet from Model:
------------------------
def self.list_web_serv_types(wsc_uid_pk) # should be called from customers
controller
ActiveRecord::Base.connection.select("SELECT gdt_number1 wbt_uid_pk,
gdt_number2
wbt_web_serv_cats_uid_fk,
gdt_alpha1 wbt_code,
gdt_alpha2 wbt_description
FROM TABLE
(service_availability_web_pkg.fn_get_web_service_type(#{wsc_uid_pk}))")
end
Thank you,

I think you may be coming into trouble because of the use of a query
string element in the form action url as well as the form parameters.
Try
<% form_tag({:controller => 'customers', :action =>
'list_services_available_at_location'}) do %>
<%= hidden_field_tag 'wsc_uid_pk', category['wsc_uid_pk'] %>
