I am working on a system to index my music library, and I think I stumbled on a bug.
When a query gets formed quote marks are not entered in the query. here is a piece of code where I believe the problem lies.
Below is the complete code.

The query is formed with this code:

INSERT INTO shoutcast_song (path, title) VALUES (%s, %s)

the data is entered at the values but no quotation marks are found.
I believe the code should be like this:

INSERT INTO shoutcast_song (path, title) VALUES ('%s', '%s')

/var/lib/python-support/python2.5/django/db/models/sql/ in execute_sql

  1. except EmptyResultSet:
  2. if result_type == MULTI:
  3. return empty_iter()
  4. else:
  5. return


  1. cursor = self.connection.cursor()
  1. cursor.execute(sql, params) ...


  1. if not result_type:
  2. return cursor
  3. if result_type == SINGLE:
  4. if self.ordering_aliases:
  5. return cursor.fetchone()[:-len(results.ordering_aliases)]

Django uses the Python DBAPI interface to submit queries, and that API handles the quoting and argument substitution. You don't need to put the quotes into the template SQL itself.

I'm going to guess this is a problem with usage, rather than a fundamental problem with Django DB interface. If you need help diagnosing your problem, I suggest asking on Django-users with a repeatable example.
