Description
Dear Developers,
I want to create a multi-language website without database.
I looked the doc and made a dropdown box for switching the language.
But when I switched the language, I saw the following error messages:
Traceback (most recent call last): File "/usr/local/lib/python2.5/site-packages/django/core/servers/basehttp.py", line 279, in run self.result = application(self.environ, self.start_response) File "/usr/local/lib/python2.5/site-packages/django/core/servers/basehttp.py", line 651, in __call__ return self.application(environ, start_response) File "/usr/local/lib/python2.5/site-packages/django/core/handlers/wsgi.py", line 245, in __call__ response = middleware_method(request, response) File "/usr/local/lib/python2.5/site-packages/django/contrib/sessions/middleware.py", line 36, in process_response request.session.save() File "/usr/local/lib/python2.5/site-packages/django/contrib/sessions/backends/db.py", line 52, in save session_key = self.session_key, File "/usr/local/lib/python2.5/site-packages/django/contrib/sessions/backends/base.py", line 152, in _get_session_key self._session_key = self._get_new_session_key() File "/usr/local/lib/python2.5/site-packages/django/contrib/sessions/backends/base.py", line 144, in _get_new_session_key if not self.exists(session_key): File "/usr/local/lib/python2.5/site-packages/django/contrib/sessions/backends/db.py", line 25, in exists Session.objects.get(session_key=session_key) File "/usr/local/lib/python2.5/site-packages/django/db/models/manager.py", line 120, in get return self.get_query_set().get(*args, **kwargs) File "/usr/local/lib/python2.5/site-packages/django/db/models/query.py", line 300, in get num = len(clone) File "/usr/local/lib/python2.5/site-packages/django/db/models/query.py", line 81, in __len__ self._result_cache = list(self.iterator()) File "/usr/local/lib/python2.5/site-packages/django/db/models/query.py", line 238, in iterator for row in self.query.results_iter(): File "/usr/local/lib/python2.5/site-packages/django/db/models/sql/query.py", line 287, in results_iter for rows in self.execute_sql(MULTI): File "/usr/local/lib/python2.5/site-packages/django/db/models/sql/query.py", line 2360, in execute_sql sql, params = self.as_sql() File "/usr/local/lib/python2.5/site-packages/django/db/models/sql/query.py", line 396, in as_sql out_cols = self.get_columns(with_col_aliases) File "/usr/local/lib/python2.5/site-packages/django/db/models/sql/query.py", line 740, in get_columns col_aliases) File "/usr/local/lib/python2.5/site-packages/django/db/models/sql/query.py", line 823, in get_default_columns r = '%s.%s' % (qn(alias), qn2(field.column)) File "/usr/local/lib/python2.5/site-packages/django/db/models/sql/query.py", line 175, in quote_name_unless_alias r = self.connection.ops.quote_name(name) File "/usr/local/lib/python2.5/site-packages/django/db/backends/dummy/base.py", line 15, in complain raise ImproperlyConfigured, "You haven't set the DATABASE_ENGINE setting yet." ImproperlyConfigured: You haven't set the DATABASE_ENGINE setting yet.
I just wondered, does session have anything to do with database?
BTW: The documentation of django does not give a clear overview of a topic. Almost everything is described pointlessly. Could you take a look at the doc of CodeIgniter (http://codeigniter.com/) and make yours more easier to understand?

Thanks. After having added SESSION_ENGINE = "django.contrib.sessions.backends.cache", it works.
I checked my settings.py, the session settings were not configured.
But I just wondered, why django uses database as the default storage for session.

Thanks for share the solution, you help me. ;)
set_language view uses django sessions if available and default sessions storage is database.
This is not a Django bug. Please ask usage questions on django-users or #django channel.
