Example Code

from couchbase.cluster import Cluster, PasswordAuthenticator

def get_bucket():
    cluster = Cluster(...)
    authenticator = PasswordAuthenticator("username", "password")
    ...

Description

This is the example code from Document: https://fastapi.tiangolo.com/advanced/nosql-databases/

As described in title, the code can not found PasswordAuthenticator from couchbase.cluster

I tried to solve this, and I found something at repository by couchbase:

from couchbase.auth import PasswordAuthenticator

also you can see this in here: https://github.com/couchbase/couchbase-python-client/blob/64be5a03d83dbcb60fa8931621700cd867bb892f/couchbase/tests/connection_t.py#L22

I think this belongs with some changes in couchbase 4.0.0.

So, the document should be updated or needs to notify the version of couchbase that is under 4.0.x

Good catch! You'd be able to give a PR?

Well, I will have a try but I'm not sure I can :/

I think the example code will be updated to, (in couchbase 3.2.0+)

from couchbase.cluster import ClusterOptions
from couchbase.auth import PasswordAuthenticator

cluster = Cluster(
        "couchbase://couchbasehost:8091?fetch_mutation_tokens=1&operation_timeout=30&n1ql_timeout=300",
+       ClusterOptions(PasswordAuthenticator("username", "password"))
    )
-   authenticator = PasswordAuthenticator("username", "password")
-   cluster.authenticate(authenticator)
