How to use two collections to authenticate zfcuser? - mongodb

Question

I use Doctrine and MongoDB ODM modules at my zf2 application. ZfcUser is used for authorization.
Is there a way to use two collections, say users and clients to authenticate via zfcuser+doctrine? I am curious, if there is a way to combine two mongo collections into one to use combined for authentication?

Answer 1

You do not need to merge the users into one collection as you can have multiple 'authentication adapters' (see ZfcUser\Authentication\Adapter\Db for an example)
These are defined within global config file: zfcuser.global.php
Each of my adapters are run in order of priority until one returns a successful authentication result.
For example; I have the following configuration for Users and Candidates entities.
/**
* Authentication Adapters
*
* Specify the adapters that will be used to try and authenticate the user
*
* Default value: array containing 'ZfcUser\Authentication\Adapter\Db' with priority 100
* Accepted values: array containing services that implement 'ZfcUser\Authentication\Adapter\ChainableAdapter'
*/
'auth_adapters' => array(
50 => 'JobboardCandidate\Authentication\Adapter\CandidateDatabaseAdapter',
75 => 'JobboardUser\Authentication\Adapter\UserDatabaseAdapter',
//100 => 'ZfcUser\Authentication\Adapter\Db', [this is the default]
),

As I understand from your question you want to get one collection with two different document types so that you can use this collection for authentication.
If you use doctrine Inheritance mapping you can have two different classes and resolve them in one collection.
In this case your Client class would extend your User class. If you would use the findAll method in your UserRepository you would get both the clients and the users in one Collection
This will help you achieve what you want:
<?php
namespace MyProject\Model;
/**
* #Document
* #InheritanceType("SINGLE_COLLECTION")
* #DiscriminatorField(name="discriminator", type="string")
* #DiscriminatorMap({"user" = "User", "client" = "Client"})
*/
class User
{
// ...
}
/**
* #Document
*/
class Client extends User
{
// ...
}
And then
$userRepository->findAll();
