Description

Running Django 1.2.3 on Ubuntu 10.04. Originally using SQLite 3.6.2, which there is known bugs for so I upgraded to 3.7.2 and am still having issues.

This was happening on OSX, then I wrapped the current_site code into functions or init statements. However, it still seems to happen on any that may be somehow reached by module loading. This does not happen anymore on OSX, and does not happen with mySQL

Here's a traceback:

And it goes through the files that call Site.objects.get_current_site() in the module loading, and finally ends with:

  File "/home/alfred/.hudson/jobs/company-sqlite/workspace/ve/lib/python2.6/site-packages/django/db/models/sql/compiler.py", line 727, in execute_sql
    cursor.execute(sql, params)

    return self.cursor.execute(sql, params)
  File "/home/alfred/.hudson/jobs/company-sqlite/workspace/ve/lib/python2.6/site-packages/django/db/backends/sqlite3/base.py", line 200, in execute
    return Database.Cursor.execute(self, query, params)
django.db.utils.DatabaseError: no such table: django_site

At this point, I'm out of ideas and can only think this is some obscure bug.

I don't know where to start to reproduce this.

Are you running the Django test suite? If so in which test does this happen? (you've not included the header of the output that appears above the traceback) or tests for your application?. What is the settings file you are using (of particular interest is the DATABASES setting.)

I'm using Debian Sid (sqlite 3.7.4) and don't see this error when running the Django suite for both trunk and the 1.2.X as of now using the tests/test_sqlite.py setting file.

I'm going to close this ticket, please reopen it if you still can reproduce it, and please include some of the details described above.

For the record -- I've had no luck reproducing this either.

  • Easy pickings unset
  • Resolution worksforme deleted
  • Severity set to Normal
  • Status changed from closed to new
  • Type set to Uncategorized
  • UI/UX unset

Just happened to me - reproducing:
use a model import in ini of an app

from configuration.models import myModel

run the testing suite with sqlite db

get:

django.db.utils.OperationalError: no such table: configuration_myModel

  • Keywords app-loading added
  • Resolution set to fixed
  • Status changed from new to closed

It isn't clear which conditions triggered this bug, but it cannot happen anymore in Django 1.7+, thanks to the app-loading refactor. Now it's explicitly forbidden to import models in __init__.py at the root of an application.
