>>>>>>>django.core.exceptions.ValidationError: [u"'' value must be either True or False."]
Have you tried to set the default value of the BooleanField as True or False? BooleanFields must have a valid boolean as default value and so happends that empty string is not a valid boolean. Change the default value to False (as exemple), run the migration again, and it should work. 2017-06-30 14:23 GMT-03:00 <[email protected]>: > So I made the ultimate error.
