My application is working in the development environment. I deployed
the application in the production and copied the data in Posetgresql
db.
When I try to insert a new "Page" using the admin application, I
receive an "IntegrityError: null value in column "id" violates not-
null constraint".
Any ideas?
Thanks...
The "Page" model class is as follows:
class Page(models.Model):
title = models.CharField('Başlık',
maxlength = 100,
core = True,
db_index = True)
slug = models.SlugField(prepopulate_from = ('title',))
body = models.TextField(blank = True,
null = True)
sections = models.ManyToManyField(Section,
blank = True,
null = True)
And this is the traceback:
