IDENTITY PLUGIN V4

This plugin includes 3 parts:

1. Grunttask
2. Openrecord Plugin
3. Actionhero Plugin

The grunttask is for synchronising roles, role_entiteies and values. Values will be synchronized automatically if your define it in your openrecord model. (see: OpenRecord Plugin/Value Sync). The OpenRecord plugin enhances your model definition to also support permissions. Permissions will be applied to find, create, update and destroy. The actionhero plugin handles the OAuth2 handshake, user and sessions management, communication with other identity apps ans some more.

Config

after installing identity your config folder should contain a identity.js config file. Every identity client has an id and secret to authenticate the application. Additionally every application has multiple roles, entities and values. An identity user can have multiple roles and every role could have multiple entities attached to it. set simplifyAdminRole to true, to combine the admin and application_admin role into admin.

Now you could grant User X permissions to Project A and B via the admin web interface of identity.

• be sure to enable the plugin within actionhero (config/api.js)
• you will need to add the identity package (npm install identity --save) to your package.json

Grunttask:

Roles Sync

`identity:sync`

Complete Value Resync

`identity:values:resync`

Helper

grunt.login(callback) gives you a login prompt + starts the actionhero server.

var done = this.async()
grunt.login(function(api, access_token, user){
  if(!access_token){
    return done(false);
  }
});

OpenRecord Plugin:

Model Permissions

	this.permission({
		role_name: true/false //global allow/deny
		role_name: {
			find: true/false, //allow/deny a specific operation
			find: function(){
				//inside a beforeFind hook
			},
			find: function(query, next){
				//inside a async beforeFind hook
			},
			
			create: true/false
			create: function(){
				//inside a beforeCreate hook
				//don't forget to call: this.errors.add('insufficient_permissions');
				return true/false
			}			
			create: function(record, transaction, next){
				//inside a beforeCreate hook
				//don't forget to call: this.errors.add('insufficient_permissions');
				next(true/false);
			}
			
			//same for update, destroy
			//modify includes create, update and destroy
				
			fields: {
				all: true/false //globall allow/deny - it's true by default
				field_name: true/false //allow/deny a specific field
				field_name: 'find' //allow only find
				field_name: ['find', 'create'] //allow find and create,
				field_name: function(){return true/false} //with custom function - no support for async functions!
			}
		}
	})

Value Sync

	this.identityValue('entity_name', function(){ //optional function to control which records should be synced
		return true/false (record scope)
	}); //in definition

Actionhero Plugin

OAuth

/api/oauth

User/Session management

/api/login, /api/logout, /api/profile, /api/user actions

Add user to connection

connection.user is the current user

The User Model has the following helper methods:

• .hasRole(role_name): boolean
• .getValues(entity_id[, role]): array
• .hasValue(entity_id, id[, role]): boolean
• `.fromGroup(entity_id, id, role): object {name: 'GroupName', id:1}

Session handling

connection.session is a object which will be saved into the actionhero cache.

Action Permissions

requireAuth: true/false, requireRole: 'admin' / ['admin', 'lead']

Identity proxy

the whole identity server is available via http://yourapp.com/api/identity/*. e.g. http://yourapp.com/api/identity/users and will only return values which belongs to the application

App comunication

api.identity.application('application_name').get('action', {param:'value'}, callback) api.identity.application('application_name').post('action', {param:'value'}, callback) api.identity.application('application_name').put('action', {param:'value'}, callback) api.identity.application('application_name').delete('action', {param:'value'}, callback)

SpecHelper

Test-Setup:

/test
	_setup.js
	actions/
	fixtures/
		sql/
			clear.sql
			default.sql

_setup.js

require('identity/spec_helper'); //require identity spec_helper

before(test.startActionhero); //starts actionhero + initializes the database
after(test.stopActionhero); //stops actionhero

//add as many users as you need for your tests
test.addUser('admin', {
  id: 1, //user's id
  first_name: 'Administrator',
  last_name: 'Admin',
  permissions: [{ //array of permissions
    role_id: 'admin', //role
    values: {} //values. e.g. {domain: [1, 2, 3]}
  }]
});

clear.sql

DROP TABLE openrecord_migrations;
# drop your tables and views here

default.sql

# add your test data here

Global object test has the following methods: test.action(name[, params, connectionParams], callback) test.loginAs(username).action(name, params, callback)

There are 2 callback-helpers: test.insufficientPermissions(callback) test.emptyResult(callback)

e.g. to test for insufficient permissions:

  it('"projects:destroy" should fail', function(done){    
    test.loginAs('user').action('projects:destroy', {id: 1}, test.insufficientPermissions(done));
  });
