How to set NULL for IntegerField instead of setting 0?
Question:
I’m uploading some data from an excel file using xlrd and turning that data into models (with mainly IntegerField values) in Django. My excel file has a bunch of missing data. Unfortunately, these missing data are converted to the value of 0 in my models, instead of NULL. This means that when my Person model doesn’t have an age, that age gets recorded as 0, instead of as NULL.
What’s the best way to change this? I’ve tried doing this:
age = models.IntegerField(blank=True, null=True)
But the blank fields still get set to 0 by default.
Answers:
Instead of using
age = models.IntegerField()
use
age = models.IntegerField(blank=True, null=True)
When we specify
blank=True, null=True
it will allow you to store null in that column
