Rails

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.
