Part 2 : Adding Flavour

At the moment we only have the business-class-model part, we need to add the relation with our datas. To do so, we will create our “resource models”. The resource models enable to link our models with the data base. Here the classes inherite from AbstractDb in order to accomplish some operations before or after different actions on the database, for instance « after/beforeDelete», « after/beforeSave » but above all to define in the constructor the table and the primary key related to our object using the “_init” method.

Part 3 : The chef's touch

The entity manager is available since version 2.1 of Magento. First and foremost I have to bring to your attention that since version 2.2, its use is not recommended by Magento anymore, here is what the framework says about the class “EntityManager” :
“It is not recommended to use the EntityManager and its infrastructure for the Persistence Entities. In the next version a new “PersistenceEntity Manager” will be created in order to cover the needs of the persistence with the API requests for the reading of the datas.”
