 If you start with following model:


 {{{
 class Thing(models.Model):
     name = models.CharField(max_length=100, default="xxx",
 verbose_name="name")
 }}}

 and change it to:


 {{{
 class Thing(models.Model):
     label = models.CharField(max_length=100, default="xxx",
 verbose_name="name")
 }}}

 Django asks:


 {{{
 Did you rename thing.name to thing.label (a CharField)? [y/N] y
 }}}

 and if you say yes, it creates a migration with:


 {{{
     operations = [
         migrations.RenameField(
             model_name='thing',
             old_name='name',
             new_name='label',
         ),
     ]
 }}}

 But if you change it to:


 {{{
 class thing(models.model):
     label = models.CharField(max_length=100, default="xxx",
 verbose_name="label")
 }}}


 if creates a migration with:


 {{{
     operations = [
         migrations.RemoveField(
             model_name='thing',
             name='name',
         ),
         migrations.AddField(
             model_name='thing',
             name='label',
             field=models.CharField(default='xxx', max_length=100,
 verbose_name='label'),
         ),
     ]
 }}}


 If you were to run this migration without thinking, you would risk losing
 data.
