Introduction​

All users associated with a single Casdoor organization share access to the organization's applications. Sin embargo, puede haber casos en los que quieras restringir el acceso de los usuarios a ciertas aplicaciones o recursos específicos dentro de una aplicación. En tales casos, puedes utilizar la característica Permission proporcionada por Casbin.

Understanding Casbin Concepts​

Before delving deeper into the topic, it is important to have a basic understanding of how Casbin works and its related concepts:

  • Model: Defines the structure of your permission policies and the criteria for matching requests against these policies and their outcomes. You can configure models in the Models page in Casdoor.
  • Policy: Describes the specific permission rules (who can access what resources with what actions). You configure policies in the Permissions page in Casdoor.
  • Adapter: An abstraction layer that shields Casbin's executor from the source of the Policy, allowing the storage of Policies in various locations like files or databases. Learn more about Adapters.

Configuring Permissions in Casdoor​

Where to Configure​

In the Casdoor Web UI, you'll work with two main pages:

  1. Models Page: Navigate to Models in the sidebar to add or edit Models for your organization.

    Model Edit Page

  2. Permissions Page: Navigate to Permissions in the sidebar to configure permission policies.

    Permission Edit Page

How Permissions Work​

Returning to the subject of permission configuration in Casdoor:

  1. Add a Model: First, create a Model for your organization in the Models page within the Casdoor Web UI.
  2. Configure a Policy: Then, add a Policy (permission rules) for your organization in the Permissions page.

El Editor en Línea de Casbin puede proporcionarte archivos de Modelo y Política adaptados a tus escenarios de uso específicos. Puedes importar sin esfuerzo el archivo de Modelo en Casdoor a través de su interfaz de usuario web para su uso por el Casbin integrado. For the Policy configuration (i.e., the Permissions page in the Casdoor Web UI), refer to the Permission Configuration guide for detailed instructions.

Using Permissions with Your Application​

Así como tu aplicación necesita hacer cumplir el control de permisos a través del Casbin integrado en Casdoor, Casdoor mismo utiliza su propio Modelo y Política para regular los permisos de acceso para las interfaces de la API a través de Casbin. Aunque Casdoor puede llamar a Casbin desde el código interno, las aplicaciones externas no pueden.

Como solución, Casdoor expone una API para que las aplicaciones externas llamen al Casbin integrado. See the Exposed Casbin APIs documentation for definitions of these API interfaces and instructions on how to use them.

Account Item Permissions​

Casdoor also provides fine-grained permission control at the user account field level through the Edit Organization page:

  • View rule: Control who can view specific user account fields
  • Modify rule: Control who can modify specific user account fields

These rules can be set to:

  • Public: Everyone has permission
  • Self: Each user has their own permission
  • Admin: Only administrators have permission

Learn more in the Account Customization documentation.

Role-Based Access Control​

Casdoor supports role-based permissions where you can assign roles to users and configure permission policies for these roles. This allows you to manage permissions at the role level rather than individual user level.
