 Hi,

 In this case, the migrations framework provides you with two choices:

 {{{
 $ python manage.py makemigrations
 You are trying to add a non-nullable field 'bar' to foo without a default;
 we can't do that (the database needs something to populate existing rows).
 Please select a fix:
  1) Provide a one-off default now (will be set on all existing rows)
  2) Quit, and let me add a default in models.py
 Select an option:

 }}}

 It seems to me like a better approach than guessing `default=''` (explicit
 being better than implicit and all).

 Is that not sufficient for your use-case?
