CachingMiddleware, with-as, AttributeError: __exit__

CachingMiddleware, with-as, AttributeError: exit

smolin

I'm trying to use the with-as construct with CachingMiddleware, following example in docs, but this throws "AttributeError: exit" - what am I doing wrong? Thanks!

from tinydb import TinyDB, where, database
from tinydb.middlewares import CachingMiddleware
from tinydb.storages import JSONStorage
db = TinyDB('tinydb_test.json', storage=CachingMiddleware(JSONStorage))
with database as db:
db.insert({'key':'keymaster', 'value':'gatekeeper'})

Hey smolin,

you use the wrong variable in your with-statement. You use database which is a TinyDB module instead of your TinyDB instance which is stored in db. The following should work:

from tinydb import TinyDB, where, database
from tinydb.middlewares import CachingMiddleware
from tinydb.storages import JSONStorage
db = TinyDB('tinydb_test.json', storage=CachingMiddleware(JSONStorage))
with db as _db:
    _db.insert({'key':'keymaster', 'value':'gatekeeper'})

Cheers!

OMG I'm a bonehead. Sorry for the line noise! And thanks for the help.

No worries! Stuff like that happens to everyone ?

Cheers!
