undefined local variable or method `acts_as_shopping_cart' - Rails 4

[luismiv85]

I am using Rails 4 and I got this error:

undefined local variable or method `acts_as_shopping_cart' for #Class:0x0000000766b320

app/models/shopping_cart.rb:
class ShoppingCart < ActiveRecord::Base
acts_as_shopping_cart
end

Anyone could help me, I couldn't find any information about this error. :(

I just updated the example app with Rails 4.1.2

Can you take a look and see if you are missing something?

I had the same problem - restarting your app's server worked. Just another childish error ;)

I am also facing the same error.

It is working fine in development and staging environment. But getting "undefined local variable or method `acts_as_shopping_cart' for #Class:0x00000007741b28 (NameError)" in production environment.

Please help.

Restarting the server solves my problem too.
