Re: Error: 'NoneType' object has no attribute 'strip'

If I remove slug code, then everything works fine. 

And can you tell me how can I expand the variables?

Thanks

Hi,

If you remove all the slug code do you still get this error? If so, then the error has nothing to do with automatically creating a slug.

Try expanding Local vars to see what "params" and "sql are.

File "e:\python\lib\site-packages\django\db\models\sql\compiler.py" in execute_sql
  920.                 cursor.execute(sql, params)
File "e:\python\lib\site-packages\django\db\backends\utils.py" in execute
  85.             sql = self.db.ops.last_executed_query(self.cursor, sql, params)

This does seem like a bug in mysql-connector. You may want to bring it up on the mysql-connector list. http://forums.mysql.com/list.php?50

You could also try using mysqlclient instead to see if you still have the problem. That's django's recommended connector.

so is there anyway to create slug automatically other than this ?

Looks like a bug in MySQL/connector (although it could just be a symptom of doing the same thing in Django as the bug poster):
