Well, I downloaded mysql.connector from the link.
I put it in the folder gluon.contrib.
I put the code below in file dal.py:
try:
try:
import contrib.mysql_connector as mysqlconn
except ImportError:
import mysql.connector
DRIVERS.append('MySQL(mysqlconn)')
except ImportError:
LOGGER.debug('no MySQL driver mysql.connector')
and it:
class MySQLAdapter(BaseAdapter):
drivers = ('MySQLdb','pymysql', 'mysqlconn')
I put it in action:
gluon.dal import from MySQLAdapter
gluon.contrib import from the mysql_connector mysqlconn
MySQLAdapter.driver = mysqlconn
And the error continues ...
