Question

I am using rails version 3.0.3.
If I run the server in the development environment, everything works ok, but when trying to run in a production environment then rails skip read the code from the file /config/ enviroment.rb.
I have the following error:

=> Booting WEBrick
=> Rails 3.0.3 application starting in production on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
Exiting

Many thanks for help

Answer 1

.. sometimes, ruby takes a wrong turn when deciding where to look for a constant. You defined the constant GRUPY_PRODUKTOWE globally and you probably access it within the Product model with just “GRUPY_PRODUKTOWE”. Try “::GRUPY_PRODUKTOWE” so it knows to look for it in the global scope.
