Bir EAV varlığı nasıl oluşturulur?

Bir EAV varlığı nasıl oluşturulur?

Bu, internette çok fazla görünen bir sorudur. Bunun nasıl yapılacağını açıklayan bazı iyi blog yazıları var, ancak hiçbiri beni tatmin etmiyor.
Ben de kendi kendine cevaplandırılan bir soruya karar verdim ve nasıl yaptığımı açıkladım ... ve işe yaramış gibi görünüyor.

Burada bir sürü kod var. Doğru okumak için cevapları 'en eski' e göre sıralayın.

Bu demonun amacı için bir modül oluşturacağım, Easylife_Newsadında bir varlık içeren adını verelim Article.
Modül, öznitelikleri yönetme bölümü ve her bir makale için bazı basit ön uç listeleme ve görünüm sayfası da dahil olmak üzere, arka uç için tam CRUD kodu ile birlikte gelir. Ayrıca, üst menüdeki bir menü öğesini, makale listesine ekler.
Aynı zamanda URL yeniden yazma, RSS besleme ve ön uç için kırıntıları içerir. Bu varlık 4 öznitelikleri olacaktır: Title, Short Description, Description, Publish DateSistem olanlara ilave olarak ( created_at, updated_at, status, in_rss, url_key).
Modül aşağıdaki dosyaları içermelidir.
