Прохожу книгу Виталия Подобы "Веб-розробка з Python та Django для Початківців". Остановился на 7 разделе - разработке моделей. А именно - работа с MySQL.
Ubuntu 14.04, virtualenvs, Django==1.7.1, MySQL-python==1.2.5, Pillow==2.8.2, wheel==0.24.0
Python==2.7.6

Answer 1

[Steve_Smith]

Решил. Удалил и создал заново db.sqlite3.

Answer 2

[Roman K]

Вы не создали миграции для других приложений. Уберите из
python manage.py makemigrations students students.

Answer 4

[sim3x]

Error creating new content types. Please make sure contenttypes is migrated before trying to migrate apps individually.

попробуй так

python manage.py migrate contenttypes
python manage.py makemigrations
python manage.py migrate

[Steve_Smith]

Тогда:
python manage.py migrate contenttypes
Operations to perform:
Apply all migrations: contenttypes
Running migrations:
No migrations to apply.
Traceback (most recent call last):
File "manage.py", line 10, in
execute_from_command_line(sys.argv)

А дальше так как и выше.

Steve_Smith: добавь в вопрос

[Steve_Smith]

sim3x: добавил

[sim3x]

Steve_Smith: если покупал, то стоит воспользоваться "Постійна підтримка та коло друзів!"

пока что обнови коннектор
pip install --upgrade MySQL-python

[sim3x]

Steve_Smith: убери и settingиз APPS свои и сделай
python manage.py makemigrations
python manage.py migrate

проверь бд - создались ли там таблици
будет нормально дял начала пару раз снести бд и создать заново

[sim3x]

Steve_Smith: не за что
