Comment (by Afonso Silva):
Based on the previous answers, a workaround for allowing `init_command`
similar to MySQL is to use a signal receiver for `connection_created`,
e.g.:
{{{#!python
from django.conf import settings
from django.db.backends.signals import connection_created
from django.dispatcher import receiver
@receiver(connection_created)
def init_command(sender, connection, **kwargs) -> None:
command = connection.settings_dict["OPTIONS"].get("init_command")
if connection.vendor == "sqlite" and command:
cursor = connection.cursor()
cursor.execute(command)
}}}
This way you could add `init_command` to your `settings.py`:
{{{#!python
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': BASE_DIR / 'db.sqlite3',
'OPTIONS': {
'init_command': 'PRAGMA journal_mode=wal;'
}
}
}
}}}
I think having this natively in Django would be useful, is there any help
needed for the previous linked PR?
