Best Practices for Naming Permissions in a System

When designing a permissions system, it’s essential to follow a clear, consistent, and scalable naming convention. Properly structured permissions improve readability, simplify management, and enhance security. This article outlines best practices for naming permissions effectively.

1. Use a Verb-Noun Structure

Permissions should clearly indicate what action is allowed on which resource. A simple and intuitive format is:

Format: verb_noun

Examples:

  • view_users
  • create_users
  • edit_users
  • delete_users
  • approve_orders
  • generate_reports

This structure makes permissions easy to understand and manage.

2. Follow CRUD for Common Actions

If your system follows CRUD (Create, Read, Update, Delete), use a standardized convention:

  • create_*
  • view_*
  • update_*
  • delete_*

Example for managing products:

  • create_products
  • view_products
  • update_products
  • delete_products

Using consistent action names reduces confusion and ensures uniformity across different modules.

3. Maintain Singular or Plural Consistency

Choose either singular (view_user) or plural (view_users) and apply it consistently.

Recommended: Use plural to indicate the resource being affected.

view_users, delete_orders
view_user, delete_order

4. Prefix Special Permissions

For actions beyond CRUD, use clear prefixes to indicate their function.

  • approve_*approve_payments
  • assign_*assign_roles
  • export_*export_reports
  • manage_*manage_settings
  • generate_*generate_invoices

Prefixes add clarity and distinguish different types of permissions.

5. Group Permissions by Modules

If your system has multiple modules, consider using a namespace-like structure:

Example for a Blog System:

  • posts.view
  • posts.create
  • posts.update
  • posts.delete
  • comments.moderate
  • users.manage_roles

Grouping permissions helps keep them structured and scalable.

6. Avoid Role-Based Permissions

Permissions should define actions, not roles. Roles should be assigned permissions but should not be part of permission names.

Bad (role-specific):

  • admin_delete_users
  • editor_publish_posts

Good (action-based):

  • delete_users
  • publish_posts

This ensures flexibility in permission management across different user roles.

7. Consider Hierarchical Permissions (Optional)

For systems with complex access control, use dot notation to define hierarchical permissions.

Example for a Project Management System:

  • projects.view
  • projects.create
  • projects.update
  • projects.delete
  • projects.tasks.view
  • projects.tasks.assign
  • projects.tasks.complete

This method ensures a logical structure for managing nested permissions.

8. Store Permissions as Strings in the Database

A good practice is to store permissions as string values in a database table.

Example Table Structure:

id name description
1 view_users "Can view user list"
2 create_users "Can add new users"
3 delete_users "Can remove users"

This allows easy assignment of permissions to roles or users and improves query efficiency.

Conclusion

A well-structured permission naming system improves readability, maintainability, and scalability. Following these best practices ensures that your permissions remain clear and easy to manage as your system grows.

Key Takeaways:

✅ Use verb-noun format

✅ Follow CRUD conventions

✅ Maintain consistent pluralization

✅ Use prefixes for special actions

✅ Group permissions by modules

✅ Avoid role-specific permissions

✅ Consider hierarchical dot notation

✅ Store permissions as strings in the database

By implementing these best practices, you create a robust and scalable permission management system for your application.
