Rails - May 2006 - collection_select and validation problems

I keep getting the error below when I use validations with 
collection_select.


You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occured while evaluating nil.inject

Extracted source (around line #22):

19:         <td>Vendor</td>
20:         <td>
21:             <!-- vendors -->
22:             <%= collection_select("pricing_survey",
"vendor_id",
@vendors, :id, :vendor_name, { :prompt => true } ) %></td>
23:     </tr>
24:     <tr>
25:         <td>Retailer</td>



Does anybody have any ideas?  I assume that rails is not querying the 
DB for the collection for my drop downs when an error occurs.

Thanks,

In the new and update methods of your controller (presumably 
pricing_survey_controller?) you should have something like

@vendors = Vendor.find(:all).

I have that for the new and edit methods but not the update and create 
methods.  I saw somewhere else that I need to explicitly call the new 
method from within create.

So instead of:

  else
         render :action => ''new''
     end

Do this.....

  else
       new
       render :action => ''new''
     end


However, now Iose my validation messages.  Also it doesn''t seem to 
conform to the DRY method if I''m calling find in every method within my
controller.

Any other suggestions?

Thanks,
phill
