# We need a special UserContext when authorizing in controller context
# because of Token authentication which has it's own permissions
# See: https://github.com/varvet/pundit#additional-context
# We use a Delegator here to have transparent / DuckType access
# to the underlying User instance in the Policy
class UserContext < Delegator
