Attachment

Introduction

The system has a built-in "Attachment" field type to support file uploads in custom collections.

The Attachment field is fundamentally a Many-to-Many association field that points to the built-in "Attachments" (attachments) collection. When an Attachment field is created in any collection, a junction table for the many-to-many relationship is automatically generated. The metadata of uploaded files is stored in the "Attachments" collection, and the file information referenced in the collection is associated through this junction table.
