Re: Error at OneToOneField in models while creating new models class
First you have to change your model name Class names starts with uppercase... My friend.. you are not making migrations... look at you have to do this: 1. Delete your migration folder 2. Delete you app table manually (DROP table) 3. python manage.py makemigrations app_name 4. migrate that's all El sábado, 22 de septiembre de 2018, 4:10:45 (UTC-5), Srinivas Gadi escribió: > > HI All, > > I am facing below error while creating a new model class. > the error pop up only at this line "user = models.OneToOneField(User)" > *"E1120:No value for argument 'on_delete' in constructor call"* > > from django.db import models > from django.contrib.auth.models import User > > class userProfile(models.Model): > user = models.OneToOneField(User) > > If I add "user = models.OneToOneField(User,*on_delete=models.CASCADE*)" > the error got subsided but the new class "userProfile" is not appearing > in admin page, under Users tab. > > Could some one please guide me how to fix this ? > > -- > Srinivas .G > 9966559383 > -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Django 1.9.8 with mysql 'Commands out of sync; you can't run this command now' exception
i know it, that problem ocurred when mysql is being used by other
process... so you can add CONN_MAX_AGE: 0 in your conection string... and
also try to use a diferent database and avoid to use multi threading
processes
