Прежде всего, если вы храните данные в БД, не храните их в одной таблице.
Вот мой пример:
schema.yml
File:
connection: doctrine
actAs: { Timestampable: ~ }
columns:
document_id: { type: integer(5), notnull: true}
name: string(255)
size: integer(11)
mime: string(255)
relations:
Document:
class: Document
local: document_id
foreign: id
type: one
onDelete: CASCADE
FileData:
local: id
foreign: file_id
type: one
foreignType: one
FileData:
connection: doctrine
columns:
file_id: { type: integer(6), notnull: true }
binary_data: { type: LONGBLOB, notnull: true }
relations:
File: { onDelete: CASCADE, local: file_id, foreign: id, foreignType: one }
