I was following the documentation for Gino (an asynchronous sqlalchemy wrapper), and when I just try to connect to an sqlite database, I get an error. Here's the code:
db = Gino()
class Server(db.Model):
__tablename__ = 'servers'
id = db.Column(db.Integer(), primary_key=True)
name = db.Column(db.Unicode(), default='noname')
async def main():
await db.set_bind('sqlite:///:memory:')
await db.gino.create_all()
asyncio.get_event_loop().run_until_complete(main())
Here's the error:
AttributeError: 'SQLiteDialect_pysqlite' object has no attribute 'init_pool'
Does this mean for sure that Gino does not support the use of an SQLite database, or could something else be going wrong?
Right at the top of their README
:
Now (early 2018) GINO supports only one dialect asyncpg.
Granted, it's now early 2019, but that doesn't look to have changed:
├── gino
│ ├── dialects
│ │ ├── __init__.py
│ │ ├── asyncpg.py
│ │ └── base.py
In asyncpg.py
they import PGDialect
from sqlalchemy and extend from that to make a class called AsyncPGDialect
which defines the init_pool
method.
