banken is ...,

Simple and lightweight authorization library for Rails inspired by Pundit. Banken provides a set of helpers which restricts what resources a given user is allowed to access.

🤔 Situation

Authorization will be grown with your app, and it will be like this.

new? refers show?, show? refers index?.

class BooksLoyalty < ApplicationLoyalty def index? @user_context.user == @record.user end def show? index? end def new? show? end end 

👍 Solution

Because each method is the same, they don't transfer their logic. Then, define_method may be nice.

class BooksLoyalty < ApplicationLoyalty [:index?, :show?, :new?].each do |method| define_method method do @user_context.user == @record.user end end end
