Description (last modified by Karen Tracey)

  • Description: Django requires the exception to have "message" attribute, but some errors don't. The real error is hidden and difficult to get.
  • How to reproduce:
    • install cx_Oracle: sudo easy_install cx_Oracle #requires python-setuptools
    • in your settings.py, use: 
            * DATABASE_ENGINE = 'oracle'
      * DATABASE_NAME = 'XE'  # your dbname here
      * DATABASE_USER = 'testuser' # your user here
      * DATABASE_PASSWORD = 'password' # your password here
      * DATABASE_HOST = 'localhost'    # your db host
      * DATABASE_PORT = ''       # leave empty if default port 1521 
      * DEFAULT_TABLESPACE = 'NONEXISTING'  # use some invalid tablespace
      * DEFAULT_INDEX_TABLESPACE = 'NONEXISTING' # here also
    • with an empty database, run syncdb: ./manage syncdb

Traceback:

...
  File "/opt/csa-1.0.0-beta/parts/django/django/core/management/commands/syncdb.py", line 80, in handle_noargs
    cursor.execute(statement)
  File "/opt/csa-1.0.0-beta/parts/django/django/db/backends/oracle/base.py", line 364, in execute
    if e.message.code == 1400 and type(e) != IntegrityError:
AttributeError: DatabaseError instance has no attribute 'message'

I should have put the settings.py part into brackets.
