module Decidim
module Abilities
# Defines the abilities for a User. Intended to be used with `cancancan`.
class BaseAbility
include CanCan::Ability
# Initializes the ability class for the given user. Automatically merges
# injected abilities fmor the configuration. In order to inject more
# abilities, add this code in the `engine.rb` file of your own engine, for
# example, inside an initializer:
#
# Decidim.configure do |config|
# config.abilities << Decidim::MyEngine::Abilities::MyAbility
# end
#
# Note that, in development, this will force you to restart the server
# every time you change things in your ability classes.
#
# user - the User that needs its abilities checked.
# context - a Hash with some context related to the current request.
