Làm thế nào để tạo một thực thể EAV?

Làm thế nào để tạo một thực thể EAV?

Đây là một câu hỏi xuất hiện rất nhiều trên web. Có một số bài viết blog tốt giải thích làm thế nào để làm điều đó, nhưng không ai trong số họ hài lòng cho tôi.
Vì vậy, tôi quyết định tự trả lời một câu hỏi và giải thích cách tôi làm nó ... và nó dường như hoạt động.

Có rất nhiều mã ở đây. Để đọc chính xác sắp xếp các câu trả lời theo 'cũ nhất'.

Phần 1

Với mục đích của bản demo này, tôi sẽ tạo ra một mô-đun, hãy đặt tên cho nó Easylife_Newscó chứa một thực thể có tên Article.
Mô-đun đi kèm với mã CRUD hoàn chỉnh cho phụ trợ, bao gồm phần quản lý các thuộc tính và một số danh sách và trang xem lối vào đơn giản cho mỗi bài viết. Nó cũng quảng cáo một mục menu trong menu trên cùng để liệt kê các bài viết.
Nó cũng chứa các ghi lại URL, nguồn cấp dữ liệu RSS và mẩu bánh mì cho frontend. Tổ chức này sẽ có 4 thuộc tính: Title, Short Description, Description, Publish Datengoài những hệ thống ( created_at, updated_at, status, in_rss, url_key).
Các mô-đun nên chứa các tập tin sau.

app/etc/module/Easylife_News.xml - mô-đun khai báo:
