  Note that model interdependencies in Django can get very complex, and squashing
  may result in migrations that do not run; either mis-optimized (in which case
  you can try again with ``--no-optimize``, though you should also report an issue),
  or with a ``CircularDependencyError``, in which case you can manually resolve it.

Use the :option:`squashmigrations --squashed-name` option if you want to set
the name of the squashed migration rather than use an autogenerated one.
