Model#find returns wrong class


I’ve one specific database view which troubles me. I set up a model

class Mytestmodel < ActiveRecord::Base
set_table_name “shop_view1”

./script/console output (development environment)

=> #<Product id: 260, …>

development.log output:
Mytestmodel Load (0.030650) SELECT * FROM “shop_view1” LIMIT 1

Why do I get an object of Product class back here? I guess this is
somewhere cached. When I change “set_table_name” to another view, I get
a Mytestmodel back, like expected. When I change it back, I always get a
Product class.

I tried this with rails 2.0.2 and 2.1.0 on ruby 1.8.6 using a postgresql
8.3 database. All caching options in environments/development.rb are
turned off.

I restarted everything on my local machine, deleted all files in ./tmp/
, stopped memcached, but this behaviour still exists.

Any clue where to search for the problem here?

ActiveRecord uses the table field “type” when determine the model name.
It doesn’t seem to matter if you have actually a inherited model of that
type or not. It would be a nice feature if you get a warning here.

Well a simple self.inheritance_column = “” to the model does the trick
