Install

Requires

rest_mysql requires python 3.10 or higher

Install via pip

foo@bar:~$ pip install rest_mysql

Updating from Rest-OC

Instead of pulling Record_MySQL from RestOC as we did in the past, change any references to rest_mysql

Old:

from RestOC import Record_MySQL
from RestOC.Record_MySQL import db_create, Record
from RestOC.Record_Base import register_type

New:

from rest_mysql import Record_MySQL
from rest_mysql.Record_MySQL import db_create, Record
from rest_mysql.Record_Base import register_type

Binary UUID and UUIDv4

If you're using uuid or uuid4 define types and you run into problems with UUID_TO_BIN and BIN_TO_UUID, you will need to install the functions, or an alias

Note

Before continuing, I would suggest switching to tuuid or tuuid4 as these represent trimmed UUIDs, which can be turned to binary and back without the use of UUID_TO_BIN or BIN_TO_UUID. If you absolutely must have full UUIDs, then choose from the below server types to continue fixing the issue.

MySQL

MySQL provides the functions, but in order for rest_mysql to be supportive of all system, it defaults to assuming the function is part of the database schema. To solve this, make aliases to the global functons

from rest_mysql.Record_MySQL import Commands

db = 'your_db_name'
Commands.execute('primary', [

	"CREATE FUNCTION `%s`.`BIN_TO_UUID`(b BINARY(16))\n" \
	"RETURNS CHAR(36) DETERMINISTIC\n" \
	"BEGIN\n" \
	"	return BIN_TO_UUID(b);\n" \
	"END" % db,

	"CREATE FUNCTION `%s`.`UUID_TO_BIN`(uuid CHAR(36))\n" \
	"RETURNS BINARY(16) DETERMINISTIC\n" \
	"BEGIN\n" \
	"	RETURN UUID_TO_BIN(uuid);\n" \
	"END" % db
])

MariaDB

MariaDB does not provide UUID_TO_BIN and BIN_TO_UUID as it has its own uuid type which doesn't support the standard sql way of storing binary UUIDs. You can add the functions to the database schema like so

from rest_mysql.Record_MySQL import Commands

db = 'your_db_name'
Commands.execute('primary', [

	"CREATE FUNCTION `%s`.`BIN_TO_UUID`(b BINARY(16))\n" \
	"RETURNS CHAR(36) DETERMINISTIC\n" \
	"BEGIN\n" \
	"	DECLARE hexStr CHAR(32);\n" \
	"	SET hexStr = HEX(b);\n" \
	"	RETURN LOWER(CONCAT(" \
			"SUBSTR(hexStr, 1, 8), '-', " \
			"SUBSTR(hexStr, 9, 4), '-', " \
			"SUBSTR(hexStr, 13, 4), '-', " \
			"SUBSTR(hexStr, 17, 4), '-', " \
			"SUBSTR(hexStr, 21)" \
		"));\n" \
	"END" % db,

	"CREATE FUNCTION `%s`.`UUID_TO_BIN`(uuid CHAR(36))\n" \
	"RETURNS BINARY(16) DETERMINISTIC\n" \
	"BEGIN\n" \
		"RETURN UNHEX(REPLACE(uuid, '-', ''));\n" \
	"END" % db
])
