So I just thought my small URL Todo django app (which I will poste the source of online soon - when I have some time to write up some README,.. too) could benefit from each urlTodo being able to be part of more than one category.
Now I already had some data in it so I was unsure. On IRC I was advised it might or might not work with automatic migrations. So I tested it.
Turns out it works ok, but does loose the assignement of the category (which was not an issue since I did not have that much data in it yet).
so all I had to do was change
category = models.ForeignKey(Category,
on_delete=models.PROTECT,
related_name='urltodos',
null=False,
verbose_name=_('category'))
to
category = models.ManyToManyField(Category,
related_name='urltodos',
verbose_name=_('category'))
and run ./manage.py makemigrations and ./manage.py migrate and then assign the categories that got lost agian.
Again I am impressed how easily this could be done with django!
