Entities in Views

Views and entities are very closely linked and it’s a breeze to expose new content entities to Views. If you’ve followed along with Chapter 7, Your Own Custom Entity and Plugin Types, and have the Product entity type set up, you’ll notice that if you try to create a View, you will have no option to make it based on products. That is because, in the entity type definition, we did not specify that it should be exposed to Views. That’s all there is to it, actually. We just have to reference a new handler:

"views_data" = "Drupal\views\EntityViewsData"

That’s it. Clearing the cache, we are now able to create Views with products that can show any of the fields, can filter and sort by them, and can even render them using view modes. All of them work consistently with the other entity types (at least fundamentally, as we will see in a moment).
