Give a name to a migration from command line option

[Raffaele Salmaso]

With south, I can (or must) give a (possibly meaningful) name to a migration step

$ ./manage.py schemamigration --auto add_a_flag

$ ./manage.py schemamigration --empty my_schema_change_name

With django migrations it is impossible, it defaults to some "random" text

$ ./manage.py makemigrations myapp --empty pippo
App 'pippo' could not be found. Is it in INSTALLED_APPS?

you must change after creation

$ ./manage.py makemigrations myapp --empty
$ cd $APP/migrations
$ mv XXXX_23833_93333.py XXXX_migration.py

A -n/--name option in makemigrations command could be ok

[Raffaele Salmaso]

I've implemented --name option it against 1.7. If it is ok I'll make a proper PR against master

[Raffaele Salmaso]

add --name/-n option to makemigrations

[amagnus]

Tested --name and -n options: working properly.

[Raffaele Salmaso]

Adding tests to master/1.7.x I've found a limitation of call_command: cannot call with name="" options (see https://code.djangoproject.com/ticket/23306)
Wondering if changing option from --name/-n to --label/-l is ok.

[Raffaele Salmaso]

Keep --name/-n option, works fine in master thanks to https://code.djangoproject.com/ticket/23309 and a workaround in 1.7.x backport (call makemigrations.Command().execute() directly).
I've added two PR with tests and a note in migrations doc.

PR against 1.7.x ​https://github.com/django/django/pull/3091

In my opinion this isn't a release blocking issue, so it doesn't qualify for backport to 1.7. I left some comments for improvement on the PR against master.

[Raffaele Salmaso]

PR updates with comments.

If the 1.7 backport is too late please close its PR (I can maintain a private "fork" or continue to use mv until 1.8) and I'll add the .. versionadded:: 1.8 string.

PR against master updated with versionadded in docs
PR against 1.7.x dropped
