I am using the User
model from django.contrib.auth.models
. I have another model called Post
which references User
through a
it may be caused by you defined related_name option in ForeignKey (or OneToOneField), if it's like this :
user = models.OneToOneField(settings.AUTH_USER_MODEL,on_delete=models.CASCADE,related_name='post')
genre = models.CharField(max_length=100)
you should use it as below :
print(user.post.genre)
Or :
print(post.user.email)
Notice : if i can see your models.py and settings.py it would be better answer.
Post.objects.filter(user=request.user).order_by('-timestamp')
Have you included the application containing the Post model in your settings.py installed apps?
e.g.
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.staticfiles',
'testapp'
# Uncomment the next line to enable the admin:
# 'django.contrib.admin',
# Uncomment the next line to enable admin documentation:
# 'django.contrib.admindocs',
)
and ran manage.py syncdb?
python manage.py syncdb
i.e does the database table for the Post model definately exist?
I did a quick test and found no problems:
from django.db import models
from django.contrib.auth.models import User
class PostModel(models.Model):
user = models.ForeignKey(User)
(test) C:\Users\Steven\django_projects\test\testproj>python manage.py shell
