Rails 4 - undefined method `call' when doing a simple query

Question

I\'m new to Rails but this seems pretty straightforward. I have a model called Game generated like this:

rails generate model Game name:string

Rails 4+ requires named scopes to be a lambda and not just a simple Relation.

Change the old version

scope :active, where(is_active: true)

to the lambda version

scope :active, lambda { where(is_active: true) }

or even shorter to

scope :active, -> { where(is_active: true) }

For more information about named scopes and how to pass parameters, I suggest reading about Scopes in the Rails Guide
