Hello!I am working on a GUI to connect to a MySQL database using MySQLdb (code in attached file). I define the cursor in lines 55-66 in the OnLogin function within the LoginDlg class.
/db= MySQLdb.connect(host='localhost', user=Username , passwd=pwd, db='Ornithobase')
self.cursor = db.cursor()/When I try to use the cursor on another part of the code (EditUser class, line 176)
/sql = 'select substring_index(CURRENT_USER(),"@",1)' login.cursor.execute(sql)/ I get this error: /AttributeError: 'LoginDlg' object has no attribute 'cursor'/ You can check the code for details, I think is better. Cheers!
