7,454 PointsI have a weird error
Here is my code: https://w.trhou.se/0a3s6wn62p
When I type Course.objects.all() I get an Import error while I have imported Course class. What does this error mean? And how can I fix it?

Treehouse Moderator 67,989 PointsThe line "sqlite3.OperationalError: no such table: courses_course
" implies that while the models.py
has been updated to include the Course
class, the database file either hasn't been initialized with a manage.py syncdb
or hasn't been updated with a migration.
