Magento 2 CRUD – Working Example with Admin Grid

Tracked this one down on my own.

First, Magento 2 requires no additional XML for creating a CRUD model. Magento 2 automatically knows how to create the needed resource model and collection objects based on a naming convention.

Magento 2 does require a

• Model Class
• Resource Model Class
• Collection Model Class
• A Schema install class

The specifics of each of these are beyond the scope of a single Stack Exchange answer, but the CMS Page model offers a simple example of each class.

https://github.com/magento/magento2/blob/develop/app/code/Magento/Cms/Model/ResourceModel/Page/Collection.php

https://github.com/magento/magento2/blob/develop/app/code/Magento/Cms/Setup/InstallSchema.php

Also, my Magento 2 code generation tool pestle now has a generate_crud_model command.

$cancelId = 5;//id for entry to update
$cancel = $this->_cancelFactory->create();
$cancel->load($cancelId);
$cancel->setCancelStatus('Review');
$cancel->save();

But as explained in the answers in here: Deprecated save and load methods in Abstract Model, load and save are deprecated. You should create service contracts for your module.
