Stuck trying to find()

[pepoluan]

So I have a piece of code that looks like this:

    async def cdb_find(self, db_name: str, mango: dict) -> List[Dict[str, Any]]:
        simplog = self.simplog
        config = self.config
        if self._cdb is None:
            simplog("Connecting to CouchDB")
            username = config.couchdb_database_username
            password = config.couchdb_database_password
            host = config.couchdb_database_host
            port = config.couchdb_database_port
            self._cdb = aiocouch.CouchDB(server=f"http://{host}:{port}/", user=username, password=password)
            await self._cdb.check_credentials()
        db = await self._cdb[db_name]
        simplog(f"CouchDB find in '{db_name}' for: {mango}")
        ## STUCK HERE ##
        result = [doc.data async for doc in db.find(mango)]
        simplog(f"CouchDB got results from {db_name}")
        return result

If I await on this, I got stuck after CouchDB find in ... for: ... line.

I can confirm that the host & port are correct: Doing curl http://$HOST:$PORT/_utils/ shows Fauxton replying.

Where did I go wrong with the code above?

Ahh okay. The problem is that mango in my code is {"selector": ... criteria ...}, while .find() expects the ... criteria ... part (it will internally wrap the criteria in {"selector": ...}.

So I fix this by passing just the ... criteria ... part to .find(), and now it works!

Indeed, the selector parameter of find() expects selectors.
