Hi Nathan,
You could create an external file/service like this:
class MyModelPolicy
def initialize(model)
@model = model
end
def view_permitted?
end
def update_permitted?
end
end
This way in your model you could have:
def view_permitted
MyModelPolicy.new(self).view_permitted?
end
The main improvements of using external services is that you can test
them by themselves, and you remove clutter from your models.
Warm regards,
Ignacio
