It is not possible to use register_converter

[Pankovea]

Description

In sqlite3 I can register converters to get correct data types.

import sqlite3
sqlite3.register_adapter(bool, int) # <-------
sqlite3.register_converter("BOOLEAN", lambda v: bool(int(v)))  # <-------

db = sqlite3.connect(':memory:', detect_types=sqlite3.PARSE_DECLTYPES)
db.execute('CREATE TABLE foo (bar BOOLEAN)')
db.execute('INSERT INTO foo VALUES (?)', (True,))
db.execute('INSERT INTO foo VALUES (?)', (False,))
for row in db.execute('SELECT * FROM foo'):
    print(row)

Output:
(True,)
(False,)

I can't use register_converter

aiosqlite.register_adapter(bool, int)
aiosqlite.register_converter("BOOLEAN", lambda v: bool(int(v)))

Thats take no effect

Output:
(1,)
(0,)

I'm still hitting this. Exact same scenario.

• OS: macOS 14.5
• Python version: 3.12.4
• aiosqlite version: 0.20.0

I was able to work around this:

sqlite3.register_adapter(bool, int)
sqlite3.register_converter("BOOLEAN", lambda v: bool(int(v)))

connection = await aiosqlite.connect(DATABASE, detect_types=sqlite3.PARSE_DECLTYPES)

Note that I had to use sqlite3 to set up the converter, and to specify the detect_types argument.
