Monarchy is a ruby gem offering a complete solution to manage an authorization access in Ruby on Rails applications. A hierarchical structure as well as built-in roles inheritance options make it the most powerful tool to control access to application data resources.

Thanks to closure_tree - a gem used to manage binary trees - Monarchy can deliver the best-in-class algorithmic performance and enables developers to forget about hierarchies and complicated structures.

If you feel limited while using rolify, feel free to use Monarchy with its advanced capacity to inherit roles and collect all accessible resources with just one method.

Usage Example

After Monarchy setup you can enjoy with roles inheritance and accessible resources.

# Create roles
admin_role = Monarchy.role_class.create(name: :admin, level: 5, inherited: true)
manager_role = Monarchy.role_class.create(name: :manager, level: 4, inherited_role: admin_role, inherited: true)

# Create resources
project1 = Project.create()
project2 = Project.create(parent: project1)
project3 = Project.create(parent: project2)
project4 = Project.create(parent: project1)

# Grant user
user.grant(:manager, project2)

# Accessible projects
Project.accessible_for(user)  # returns [project1, project2, project3]

# User inherited roles
user.roles_for(project1) # returns a default role eg. [guest_role]
user.roles_for(project2) # returns [manager_role]
user.roles_for(project3) # returns [admin_role]
user.roles_for(project4) # returns empty array []

# Graphical visualization

#                              project1 (default role, eg. guest)
#                                 |
#                                 |
#   (granted as manager) project2   project4 (no access)
#                           |
#                           |
#                        project3 (admin | inherited role from manager_role)
