`adonis-lucid-permission`

Library for associate adonisjs lucid ORM models with roles and permissions

Requisites

Requires @adonisjs/core >= 6.5.0 and @adonisjs/lucid >= 20.5.1;

Installation

NPM

npm i adonis-lucid-permission

YARN

yarn add adonis-lucid-permission

PNPM

pnpm add adonis-lucid-permission

After install call configure:

node ace configure adonis-lucid-permission

Usage

After install and configure, apply HasAuthorizable to a Model

import { compose } from '@adonisjs/core/helpers';
import { BaseModel } from '@adonisjs/lucid/orm';
import { withAuthorizable } from 'adonis-lucid-permission';

const HasAuthorizable = withAuthorizable({
  rolesPivotTable: 'user_has_roles',
  permissionsPivotTable: 'user_has_permissions',
});

export default class User extends compose(BaseModel, HasAuthorizable) {
  // ...columns and props
}

And create the pivot-table migration file with:

node ace permissions:pivot-table

And ready. User model can all methods for associate roles and permissions

Role and Permission model

Roles and Permissions are just Lucid models that can be directly managed like any other model

import { Permission } from 'adonis-lucid-permission/services/permission';
import { Role } from 'adonis-lucid-permission/services/role';

const role = await Role.create({ name: 'writer' });
const permission = await Permission.create({ name: 'edit-posts' });

Managing permissions

You can manage permissions for roles and models using the same methods

// Assigning permissions
await role.givePermissionTo('do-things');

// Removing permissions
await user.revokePermissionTo('do-things');

// Synchronize permissions
await role.syncPermissions('do-things', 'try-things');

Checking for permissions

// Checking permissions
await role.hasPermissionTo('do-things'); // returns true or false
await user.checkPermissionTo('do-things'); // returns true or throws

// Returns true if the model has any of the given permissions
await role.hasAnyPermission('do-things', 'try-things');

// Returns true if the model has all of the given permissions
await user.hasAllPermissions('do-things', 'try-things');

// Returns all permission names
await user.getPermissionNames();

Managing Roles

You can manage roles for models using the withAuthorizable mixin

// Assign role
await user.assignRole('admin');

// Revoke role
await user.revokeRole('admin');

// Synchronize roles
await user.syncRoles('admin', 'writer', role);

Checking for roles

Generally you should be checking against permissions vs checking for roles, but if you want to check against a role instead use one of the following methods

await user.hasRole('admin');

// Returns true if the model has any of the given permissions
await role.hasAnyRoles('admin', 'writer');

// Returns true if the model has all of the given permissions
await user.hasAllRoles('admin', 'writer');

// Returns all role names
await user.getRoleNames();

Accessing direct and role permissions

// Check if the model has the permission directly
await user.hasDirectPermission('do-things');

// Check if the model has the permission via role
await user.hasPermissionViaRole('do-things');

// Get all direct permissions
await user.getDirectPermissions();

// Get all permissions via roles
await user.getPermissionsViaRoles();

// Get all permissions combined
await user.getAllPermissions();

// Check if the model has the permission directly or via role
await user.withPermissionTo('do-things');

// Returns true if the model has any of the given permissions directly or via role
await user.canAnyPermission('do-things', 'try-things');

Protect routes with middlewares

After version 1.1.0 added middlewares for protect routes using roles, permissions, or roles and permissions. Please check your start/kernel.ts file and middleware router named register like:

export const middleware = router.named({
  //...
  role: () => import('adonis-lucid-permission/role_middleware'),
  permission: () => import('adonis-lucid-permission/permission_middleware'),
  roleOrPermission: () => import('adonis-lucid-permission/role_or_permission_middleware'),
  //...
});

And in your router file, use after middleware.auth(), example:

import router from '@adonisjs/core/services/router';
import { middleware } from '#start/kernel';

router
  .post('projects', async ({ auth }) => {
    console.log(auth.user); // User
  })
  .use([
    middleware.auth(),
    middleware.permission({ permissions: ['publish projects', 'edit projects'] }),
  ]);

router
  .post('posts', async ({ auth }) => {
    console.log(auth.user); // User
  })
  .use([middleware.auth(), middleware.role({ roles: ['editor', 'administrator', 'publisher'] })]);

router
  .post('projects', async ({ auth }) => {
    console.log(auth.user); // User
  })
  .use([
    middleware.auth(),
    middleware.roleOrPermission({ roleOrPermission: ['administrator', 'publish projects'] }),
  ]);
