I see that in the develop branch of the Magento 2 repo the methods load and save from Magento\Framework\Model\AbstractModel class are deprecated.
But there are a gazillion classes in the core that extend this class and use save and load.
When creating my own module for the CRUD part of my entities I follow the same guidelines as a core module does.
But since these methods are deprecated I would rather be prepared for the future.
What should I use instead of them? Or I should extend something else?


You should use Module Service Contract.

For example for product you should use ProductRepositoryInterface

If Module Service Contract is not available you can use ResourceModel to save entities.

  • I see. This makes sense. But can you confirm that all the core CRUD modules will have service contracts at one point? – Marius May 12 '16 at 6:10

    I see that the implementation of ProductRepositoryInterface still uses load in the methods get and getById. Should I use the resource model for my module instead of this load method? – Marius May 12 '16 at 9:05

    yes, for your module better to use ResourceModel in your Module SL – KAndy May 12 '16 at 10:39

    can you please give some example code for how we can use ResourceModel – Yogesh Karodiya Nov 8 '16 at 9:45

    Do you have any examples? I looked at the official review and newsletter modules, and they are calling "save" directly. I cannot find an example of using ResourceModel. I have it defined for my module, but how to use it? – Jānis Elmeris Nov 15 '17 at 15:38

From what I understood, what is going to happen is Magento is going to switch to hydrators with extract() and hydrate() methods.

This link used to work but it seems like Magento team rolled it back: https://github.com/magento/magento2/blob/develop/lib/internal/Magento/Framework/Model/Entity/EntityHydrator.php

You can find the history of the commit here though: https://github.com/magento/magento2/tree/09132da06e18dde0f90aabfc962db2bc19b64f3c/lib/internal/Magento/Framework/Model/Entity

The important files are:

  • EntityHydrator.php
  • EntityMetadata.php
  • HydratorInterface.php
  • MetadataPool.php

I also suggest you check out the files under the Action folder as well as the Sequence files.

From what I understood (I may be totally wrong here):

  • the files under the Action folder are CRUD actions
  • the Sequence files are iterators ?

That was a conversation that happened a while ago (was it Alan Storm who mentionned it ? can't remember) so I'm not sure if Magento team is still going that way.


From my research, the internal Magento ticket regarding this change is MAGETWO-50676, here are the related commits I managed to find:

There's probably more TBH but I don't feel like browsing the entire repo for commit messages ^^

If you're not familiar with hydrators, I suggest you check that link out: http://www.webconsults.eu/blog/entry/108-What_is_a_Hydrator_in_Zend_Framework_2

Update from 2.1

Magento is now using the EntityManager class to replace the inheritance you can find more information here: Magento 2.1: using the entity manager


See description in the class code https://github.com/magento/magento2/blob/2.1/lib/internal/Magento/Framework/Model/AbstractModel.php#L626

    Any idea when load save and delete are going to go away? – Marius Jun 22 '17 at 6:02

    They will stay for 2-3 minor releases – Anton Kril Jun 24 '17 at 19:53

An alternative to Magento 2 Deprecated Load Method is the resource model load method.

public funtion getCustomer($id)
   $customerModel = $this->customerFactory->create();
   $this->customerResource->load($customerModel, $id);

here the first parameter is the model object and the second parameter is id you want to load.

An alternative to Magento 2 Deprecated Save Method is the resource model save method.

public funtion save($taskData)
   $taskModel = $this->taskFactory->create()->setData($taskData);

save method accepts only one parameter that is your model object.
