When setting a new FileField in a model to blank=True, it asks to specify a default value for existing rows when running a schemamigration. This would lead me to believe that I should set null = True which has been addressed
Here: How to make FileField in django optional?
And Here: Django - how to make ImageField/FileField optional?
However, the docs https://docs.djangoproject.com/en/dev/ref/models/fields/#null explicitly say that it is not recommended to set the default to null.
If this is the case, what are the alternatives for setting a default and making a FileField optional without using null?
