Python Mysql request thru query storage for B3 (BigBrotherBot) - python-2.7

Question

I try to retrive MysqlDatabase Data from a given Database (maprating).
When i call the command !maprating i get the following Error:
230205 14:19:09 DEBUG 'AdminPlugin: handle command !maprating'
230205 14:19:09 VERBOSE "RCON sending (127.0.0.1:27960) 'tell 0 ^3: ^8[pm]^7 ^7There was an error processing your command'"
230205 14:19:09 ERROR "Handler AdminPlugin could not handle event Say: AttributeError: 'Cursor' object has no attribute 'fetchone'
This is the code i use for the maprating query. It should get me the average rating of the maps.
Important! the Python syntax needs to be for Python 2.7.* as the B3 Bot can only handle to this version of python.
def cmd_maprating(self, data, client, cmd=None):
map_name = self.console.game.mapName
query = "SELECT map_name, SUM(rating) AS total_rating FROM mapratings WHERE map_name = %s GROUP BY map_name"
cursor = self.console.storage.query(query, (map_name,))
if cursor.rowcount == 0:
client.message("No ratings for map %s" % map_name)
else:
result = cursor.fetchone()
client.message("Map %s has a total rating of %d" % (result['map_name'], result['total_rating']))
**Here is the complete code.

Thank you.

Answer 1

I got the problem solved by using the curser.getRow instead of fetchone() command that is supported by the B3 Bot given librarys.
def cmd_maprating(self, data, client, cmd=None):
map_name = self.console.game.mapName
query = "SELECT map_name, SUM(rating) AS total_rating FROM mapratings WHERE map_name = %s GROUP BY map_name"
cursor = self.console.storage.query(query, (map_name,))
if cursor.rowcount == 0:
client.message("No ratings for map %s" % map_name)
else:
result = cursor.getRow()
rating = result['total_rating']
if rating >= 0:
client.message("Map %s has a total rating of ^2%d" % (result['map_name'], rating))
else:
client.message("Map %s has a total rating of ^1%d" % (result['map_name'], rating))
