У меня django.db.utils.InterfaceError: (0, '') ошибка на django.
Я погуглил и обнаружил, что эта ошибка связана с django mysql подключением.
То, что я сделал, это просто например,
from django.core.management.base import BaseCommand
from ...models import Issue
class Command(BaseCommand):
def handle(self, *args, **options):
print("dbconnection test:")
obj = Issue.objects.get(id=1)
print(obj.id)
exit()
В некоторых статьях показано решение с закрытием соединения
cursor = connection.cursor()
cursor.execute(query)
cursor.close()
, но у меня даже нет возможности connection.close()
Проблема возникает здесь /usr/local/lib/python3.6/site-packages/MySQLdb/connections.py
def query(self, query):
# Since _mysql releases GIL while querying, we need immutable buffer.
if isinstance(query, bytearray):
query = bytes(query)
_mysql.connection.query(self, query)
Я действительно ценю любую помощь. Большое спасибо.
Я добавил CONN_MAX_AGE Нет в настройках дБ, но напрасно.
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
....
'HOST': env('DATABASE_HOST'),
'PORT': env('DATABASE_PORT'),
'OPTIONS': {
'charset': 'utf8mb4',
'init_command': "SET sql_mode='STRICT_TRANS_TABLES'"
},
'CONN_MAX_AGE' : None ## add here
}
}
Это трассировка стека
