File Managed Alter

Submitted by daniel on

This is simple utility module that enables you to increase the length of the 'uri' field used by the 'file_managed' table which is in turn used by Drupal's 'file' entity. This module increases the maximum length from varchar(255) to varchar(2048).


By default, in Drupal there is a restriction of 255 chars on the varchar size or length of the uri field in the file_managed table. In some circumstances this is not sufficient and may result in an exception.

Please try again later.Drupal\Core\Entity\EntityStorageException: SQLSTATE[22001]: String data, right truncated: 1406 Data too long for column 'uri' at row 1: INSERT INTO "file_managed" ("uuid", "langcode", "uid", "filename", "uri", "filemime", "filesize", "status", "created", "changed") VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6, :db_insert_placeholder_7, :db_insert_placeholder_8, :db_insert_placeholder_9); Array

Reasons to increase the uri length

Microsoft Internet Explorer has a maximum uniform resource locator (URL) length of 2,083 characters. Internet Explorer also has a maximum path length of 2,048

If you are using the GET method, you are limited to a maximum of 2,048 characters, minus the number of characters in the actual path.

RFC 2616, "Hypertext Transfer Protocol -- HTTP/1.1," does not specify any
requirement for URL length.

Reasons to NOT increase the uri length

Other modules both core and contrib may make assumptions about the length of this field.
