hadrien / pyramid_mongokit Goto Github PK

I’m using multiple databases thanks to MongoConnection, and to get all database names related to the DB prefix I need to filter the result of database_names myself:

[name for name in conn.database_names() if name.startswith(conn.db_prefix)]

MongConnection could override database_names to do this for me.

We see this during application startup:

UserWarning: database name or authSource in URI is being ignored. If you wish to authenticate to showcase_devlocal, you must provide a username and password.
  "must provide a username and password." % (db_name,))

The client should be instantiated without DB name. See https://jira.mongodb.org/browse/PYTHON-477 for details

mongo db uri may contain options (http://docs.mongodb.org/manual/reference/connection-string/) and these options are included in MONGO_DB_NAME

example;
MONGO_URI = mongodb://localhost/my_glorious_db?replicaSet=rs_local_a

will give MONGO_DB_NAME = my_glorious_db?replicaSet=rs_local_a

Currently we can use config.include('pyramid_mongokit') to set up the connection object and request.mongo_db to access the database, but we have to import functions in order to create indices and register document classes at startup time. It would be nice to have methods on the config object instead.

SingleDBConnection uses naïve string formatting to combine MONGO_URI and MONGO_DB_NAME; if one passes parameters in query string (e.g. MONGO_URI=mongodb://localhost/?replicaSet=rs_local_a), then this error will happen: ConnectionFailure: localhost:27017 is not a member of replica set rs_local_a/my_database

I’ll submit a fix that uses urlparse.
