Hi there,
I''m running my app using rails 2.0.2.
When running the create method in my controller, I get the following
error:
----------------------------------
You have a nil object when you didn''t expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]
app/controllers/routes_controller.rb:39:in `create''
Parameters:
{"commit"=>"Create",
"route"=>{"name"=>"testroute"},
"user_ids"=>["1",
"4"],
"heading_id"=>"0"
---------------------------------
Here''s line 39 in the controller:
@route.users = User.find(@params[:user_ids]) if @params[:user_ids]
I don''t understand what''s going on here. The following works
when I run
it in the console:
User.find([1,4])
I''m at a loss as to why this doesn''t work.
Can anyone help me here?
Thanks!

This method doesn''t get run much and could have gone unnoticed. Thanks so much for your help.

You''re welcome Jason. You can check out this post for more detail on @params vs. params http://weblog.rubyonrails.org/2006/4/25/use-params-not-params Best.
