Adonis ACL

Adonis ACL adds role based permissions to built in Auth System of Adonis Framework.

Installation

1. Add package:

$ adonis install @rocketseat/adonis-acl

2. Register ACL providers inside the your start/app.js file.

const providers = [
  ...
  '@rocketseat/adonis-acl/providers/AclProvider',
  ...
]

const aceProviders = [
  ...
  '@rocketseat/adonis-acl/providers/CommandsProvider',
  ...
]

3. Setting up traits to User model.

class User extends Model {
  ...
  static get traits () {
    return [
      '@provider:Adonis/Acl/HasRole',
      '@provider:Adonis/Acl/HasPermission'
    ]
  }
  ...
}

4. Setting up middlewares inside start/kernel.js file.

const namedMiddleware = {
  ...
  is: 'Adonis/Acl/Is',
  can: 'Adonis/Acl/Can',
  acl: 'Adonis/Acl/Acl',
  scope: 'Adonis/Acl/Scope'
  ...
}

For using in views

const globalMiddleware = [
  ...
  'Adonis/Acl/Init'
  ...
]

6. Publish the package migrations to your application and run these with adonis migration:run.

$ adonis acl:setup

Working With Roles

Create Role

Lets create your first roles.

const roleAdmin = new Role();
roleAdmin.name = "Administrator";
roleAdmin.slug = "administrator";
roleAdmin.description = "manage administration privileges";

await roleAdmin.save();

const roleModerator = new Role();
roleModerator.name = "Moderator";
roleModerator.slug = "moderator";
roleModerator.description = "manage moderator privileges";

await roleModerator.save();

Before, you should do first, use the HasRole trait in Your User Model.

class User extends Model {
  ...
  static get traits () {
    return [
      '@provider:Adonis/Acl/HasRole'
    ]
  }
  ...
}

Attach Role(s) To User

const user = await User.find(1);
await user.roles().attach([roleAdmin.id, roleModerator.id]);

Detach Role(s) From User

const user = await User.find(1);
await user.roles().detach([roleAdmin.id]);

Get User Roles

Get roles assigned to a user.

const user = await User.first();
const roles = await user.getRoles(); // ['administrator', 'moderator']

Working With Permissions

Create Role Permissions

const createUsersPermission = new Permission();
createUsersPermission.slug = "create_users";
createUsersPermission.name = "Create Users";
createUsersPermission.description = "create users permission";
await createUsersPermission.save();

const updateUsersPermission = new Permission();
updateUsersPermission.slug = "update_users";
updateUsersPermission.name = "Update Users";
updateUsersPermission.description = "update users permission";
await updateUsersPermission.save();

const deleteUsersPermission = new Permission();
deleteUsersPermission.slug = "delete_users";
deleteUsersPermission.name = "Delete Users";
deleteUsersPermission.description = "delete users permission";
await deleteUsersPermission.save();

const readUsersPermission = new Permission();
readUsersPermission.slug = "read_users";
readUsersPermission.name = "Read Users";
readUsersPermission.description = "read users permission";
await readUsersPermission.save();

Before, you should do first, use the HasPermission trait in Your User Model.

class User extends Model {
  ...
  static get traits () {
    return [
      '@provider:Adonis/Acl/HasPermission'
    ]
  }
  ...
}

Attach Permissions to Role

const roleAdmin = await Role.find(1);
await roleAdmin
  .permissions()
  .attach([
    createUsersPermission.id,
    updateUsersPermission.id,
    deleteUsersPermission.is,
    readUsersPermission.id
  ]);

Detach Permissions from Role

const roleAdmin = await Role.find(1);
await roleAdmin
  .permissions()
  .detach([
    createUsersPermission.id,
    updateUsersPermission.id,
    deleteUsersPermission.is,
    readUsersPermission.id
  ]);

Get User Permissions

Get permissions assigned to a role.

const roleAdmin = await Role.find(1);
// ['create_users', 'update_users', 'delete_users', 'read_users']
await roleAdmin.getPermissions();

or

const roleAdmin = await Role.find(1);
// collection of permissions
await roleAdmin.permissions().fetch();

Protect Routes

Syntax:

and - administrator and moderator

or - administrator or moderator

not (!) - administrator and !moderator

// check roles
Route.get("/users").middleware([
  "auth:jwt",
  "is:(administrator or moderator) and !customer"
]);

// check permissions
Route.get("/posts").middleware(["auth:jwt", "can:read_posts"]);

// check roles and permissions
Route.put("/posts").middleware(["auth:jwt", "acl:admin or update_posts"]);

// scopes (using permissions table for scopes)
Route.get("/posts").middleware(["auth:jwt", "scope:posts.*"]);

The acl middleware is used to verify both a role and a permission at the same time, but for it to work properly it is necessary that a role and a permission doesn't share the same name.

Vow trait

adonis-acl has a trait to make it easy to use it while testing with adonis-vow. To enable the addRoles and addPermissions methods, you need to add the trait Acl/Client.

The arguments must be your roles or permissions.

const [admin, moderator] = await Role.all();
addRole(admin, moderator);

const [create, read, update, del] = await Permission.all();
addPermission(create, read, update, del);

Here's an example of how to use it inside a test:

const { test, trait } = use("Test/Suite")("Awesome test");

trait("Test/ApiClient");
trait("Auth/Client");
trait("Acl/Client");

test("awesome some test", async ({ client }) => {
  const role = await Role.find(1);
  const permission = await Permission.find(1);
  const user = await User.find(1);

  const response = await client
    .put("/posts/1")
    .loginVia(user)
    .addRoles(role)
    .addPermissions(permission)
    .end();
});

Both addRoles and addPermissions inject roles and permissions on the user that was passed by loginVia method, so it is vital to call them after loginVia as seen on the example above.

It is also crucial that trait("Auth/Client") is called before trait("Acl/Client").

Using commands

Command	Description	Options
adonis acl:setup	Publish the package migrations to your application
adonis acl:role <slug> [name][description]	Make a new role	--permissions=<slug list of permissions separated by comma> Attach permissions to the role
adonis acl:permissions <slug> [name][description]	Make a new permission or updates the name and description if the slug was found

Using in Views

@loggedIn
  @is('administrator')
    <h2>Protected partial</h2>
  @endis
@endloggedIn

or

@loggedIn
  @can('create_posts or delete_posts')
    <h2>Protected partial</h2>
  @endcan
@endloggedIn

or

@loggedIn
  @scope('posts.create', 'posts.delete')
    <h2>Protected partial</h2>
  @endscope
@endloggedIn
