So, let's say I have a model Car in the code with some changes.
These changes have not been applied, and I try to run reset_migrations.

ALL the migrations will be faked, including the last migration which has the changes of the Car model. So it's never actually applied.

Thanks for your good work!

Example:

If I need reset migrations starting from my third migration:

    python manage.py reset_migration app1 --starting 003

When I've executed command
python manage.py reset_migrations treasure
I've got error:

Traceback (most recent call last):

I suggest reason is cyrillic symbols in my project files.

Thank you!

Love this.

Would be even better with an option to drop the tables that it just reset and apply the new initial migration.

It may want an "Are you sure?" prompt to minimize risk of accidents and a -y or -f option to to answer yes automatically or force that (for scripts).

This is admittedly for a particular use case at the outset of a project when models are evolving rapidly and there is no live data yet per se, and whatever data is in there is from initial and test fixtures and easy to reload anyhow.

This extra feature would bring this use case into its one command turn-key solution scope. And would rock.

Hi Man,
I'm trying to use your script and after run
python manage.py reset_migrations app1 app2 app3...
I got this
..../reset_migrations.py", line 17, in delete_line
print_function('Deleting line in %s' % filename)
AttributeError: _Feature instance has no call method

Do you have any idea what's going on?
***My apps has dependencies

thanks in advance :)

Resetting voucher from https://github.com/django-oscar/django-oscar caused an error - it has a problem with the dependency app basket.

it should be straight forward.

Thanks,

It's a very minor issue, but I notice two typos in README.MD.

There are a couple of references to "INSTALL_APPS" but they should say "INSTALLED_APPS".

I realize most people already would already know what it should say, but there might be newbies who take the instruction literally.

It'd be nice if the package would be made compatible with python3, or a comment is made that it's not.
