An little nicer way to handle authorization rules for your lucky app

1. Add the dependency to your shard.yml:

   dependencies:
     lucky_can:
       github: confact/lucky_can

2. Run shards install

1.  require "lucky_can"

2. create an policies directory where all your policies will be. Now you will Add an require for that directory to the app.cr file before pages require. Add this: require "./policies/**"

3. now you can create your policies in policies directory.

class TeamPolicy < LuckyCan::BasePolicy
  can show, team, current_user do
    return false if current_user.nil?
    team.users.include?(current_user)
  end
end

this generate following methods for you to use by an macro:

• TeamPolicy.show?(team, current_user) - for simple bool check if the user have access to the team.
• TeamPolicy.show_not_found?(team, current_user, context) - Return an Lucky::RouteNotFoundError if the code in the block return false.
• TeamPolicy.show_forbidden?(team, current_user, context) - Return an LuckyCan::ForbiddenError if the code in the block return false.

1. Fork it (https://github.com/confact/lucky_can/fork)
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create a new Pull Request
