"No changes detected" with SQLite, wrong answer

Description

If you make any changes, that SQLite doesn't allow to change via ALTER sql statement, Django shouldn't say "No changes detected", but it should say "You're using a piece of chick, so we cannot ALTER your changes".

Which changes are these?

comment:2 by Dan <d.kzlv.ru@…>, 11 years ago

For example, changing name of a field.

I'm not sure how to produce the behavior you're describing. For example if I change the Choice.votes field in the tutorial to vote, I get the following prompt:

$ python manage.py makemigrations polls
Did you rename choice.votes to choice.vote (a IntegerField)? [y/N] y
Migrations for 'polls':
  0002_auto_20140625_1306.py:
    - Rename field votes on choice to vote

SQLite does have ​some documented caveats, but as far as I know, the autodetector behavior is independent of the database you are using.
