Hello.

I have made a model name is User, so have created "users" table. and I made Customer class inhrtied by User Class.

When I call the Customer class in some controller, the controller passed error msg to me.

It seems that controller doesn't find table("users") when make Customer instance.

previously, thanks for your help.

No, it's not finding your customer class because it's not in customer.rb. Either put Customer in customer.rb or require user with require_dependency

ALso you don't need that initializer to set the type column (rails will do that for you). It's also not how initialize is spelled. Fred
