Using django 10 and postgres 9.4.
After the website full setup I noticed that I cannot create new objects from my applications, default django apps like users are OK.
ran makemigrations and migrate afterwords, and when re trying it says nothing to migrate.
To make it simple:
When entering django shell and typing
from users.models import *
User.objects.all()
Out[3]: [<User: root>]
but :
UserProfile.objects.all()
Out[4]:
<repr(<django.db.models.query.QuerySet at 0x39b4610>) failed: django.db.utils.ProgrammingError: relation "users_userprofile" does not exist
LINE 1: ...."is_superuser", "users_userprofile"."wight" FROM "users_use...
^
UserProfile is my site users with onetoone to django.contrib.auth
class UserProfile(models.Model):
user = models.OneToOneField(User)
Thanks
you must import the django.setup before doing the operation:
import django
django.setup()

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"
section/models.py
from django.db import models
from django.contrib.auth.models import User
class userProfile(models.Model):
user = models.OneToOneField(User)
admin.py
from django.contrib import admin
from section.models import userProfile
admin.site.register(userProfile)
If I add below entry with "on_delete=models.CASCADE"
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.
Also run migrations:
C:\Users\srini\djangoProjects\college>python manage.py makemigrations
No changes detected
C:\Users\srini\djangoProjects\college>python manage.py migrate
Operations to perform:
Apply all migrations: admin, auth, contenttypes, sessions
Running migrations:
No migrations to apply.
Could some one please guide me how to fix this ?
Include your app_name in INSTALLED_APPS list in settings.py.
Then try migrations. After that check Admin after running the server.
Version Info: Python 2.7, Django 1.9, Oscar Commerce - VERSION = (1.3)
I am trying to customize Products and few other models in the catalogue app following the documentation.
I have forked catalogue app (to myproject/forked_apps/catalogue) as per documentation documentation and did this in models.py:
from django.db import models
from oscar.apps.catalogue.abstract_models import AbstractProduct
class Product(AbstractProduct):
is_active = models.BooleanField(default=False)
from oscar.apps.catalogue.models import *
I have already included the modified catalogue app, in the INSTALLED_APPS in settings.py as an argument for get_core_apps function, as stated in docs (so my local app is replacing the original app from Oscar).
INSTALLED_APPS = [
...
] + get_core_apps(['forked_apps.catalogue'])
Migrations are also copied from oscar.apps.catalogue to my local app.
When I'm trying to make migrations I'm getting this error all the time:
RuntimeError: Conflicting 'product_product_options' models in application 'catalogue': <class 'oscar.apps.catalogue.models.Product_product_options'> and <class 'forked_apps.catalogue.models.Product_product_options'>.
I tried to remove all migrations from my local catalogue app (the I copied before from Oscar app), then it works, but all new migrations are created in Oscar source code folder, but I need them to be in my project...
How do I get over this error ?
Make sure you're using the following wherever you use the Product model:
from oscar.core.loading import get_model
Product = get_model('catalogue', 'Product')
if you, in some place of your code write an import just like this:
from oscar.apps.catalogue.models import Product
you will ran into this issue.
Version Info:
Python 3.4, Django 1.8, Oscar Commerce - VERSION = (1, 2, 1, 'final')
I am trying to customize Products in the catalogue app following the documentation.
Having forked the catalogue app, I have defined models.py as follows:
from django.db import models
from oscar.apps.catalogue.abstract_models import AbstractProduct
class Product(AbstractProduct):
is_active = models.BooleanField(default=False)
from oscar.apps.catalogue.models import *
I have already included the modified catalogue, in the INSTALLED_APPS in settings.py as a list, as suggested for a similar problem here.
INSTALLED_APPS = INSTALLED_APPS + get_core_apps(
['app.gravytrain.catalogue',])
Have copied the migration folder from oscar/apps/catalogue to my custom app.
However running migration causes the following error:
RuntimeError: Conflicting 'product_product_options' models in
application 'catalogue': <class
'gravytrain.catalogue.models.Product_product_options'> and <class
app.gravytrain.catalogue.models.Product_product_options'>.
How do I get over this error ?
If you want to import some models, you need use get_model function.
For example:
from oscar.core.loading import get_model
Product = get_model('catalogue', 'Product')
I had the same error. I have also included "from oscar.apps.catalogue.models import *" in the top of the model. Once I was removed it, that issue fixed.
I'm having trouble in Django 1.7, I am trying to save a user to a table, but I'm getting an error that the table does not exist.
Here is the code I'm executing:
from django.conf import settings
from django.contrib.auth import BACKEND_SESSION_KEY, SESSION_KEY, get_user_model
User = get_user_model()
from django.contrib.sessions.backends.db import SessionStore
from django.core.management.base import BaseCommand
class Command(BaseCommand):
def handle(self, email, *_, **__):
session_key = create_pre_authenticated_session(email)
self.stdout.write(session_key)
def create_pre_authenticated_session(email):
user = User.objects.create(email=email)
session = SessionStore()
session[SESSION_KEY] = user.pk
session[BACKEND_SESSION_KEY] = settings.AUTHENTICATION_BACKENDS[0]
session.save()
return session.session_key
However, at
user = User.objects.create(email=email)
I get an Error message :
django.db.utils.OperationalError: no such table: accounts_user
Here is the user model at accounts/models.py that I'm trying to use to build the table:
from django.db import models
from django.utils import timezone
class User(models.Model):
email = models.EmailField(primary_key=True)
last_login = models.DateTimeField(default=timezone.now)
REQUIRED_FIELDS = ()
USERNAME_FIELD = 'email'
def is_authenticated(self):
return True
I've run sqlmigrate against this migration with 'manage.py accounts 0001.initial' and I have gotten the correct create table SQL back, but running 'manage.py migrate' gives me the following :
Operations to perform:
Apply all migrations: sessions, admin, lists, contenttypes, accounts, auth
Running migrations:
No migrations to apply.
The migration is just the result of running 'makemigration' from the shell, no custom code. I do see accounts listed in the included applications, but the migration isn't being ran, so my site is in an odd spot where Django says the table is missing when I try to use it, but Django says it exists when I try to run the migration to create it. Why does Django erroneously think that the table already exists when I can look at the database and see that it doesn't?
#user856358 Your comment about the other sqlite file seems like the root cause. I encountered the same error, and it was resolved by removing that file and running another migration. In my case, the file was located as specified in settings.py:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, '../database/db.sqlite3'),
}
}
By removing the .sqlite3 file there, I was able to successfully run the migration and resolve the no-such-table error...
django.db.utils.OperationalError: no such table: accounts_user
$ rm ../database/db.sqlite3
$ python3 manage.py migrate
I am unable to use syncdb because my app uses some MySQL views. I have run manage.py sqlall <app>, but this does not output the SQL for django_content_type table or the auth_permission tables. I have also had a look into south and django evolution, but they both require syncdb, and I'm not sure they would help anyway.
I have manually added some models to the tables, but this is getting frustrating, and having installed the dbsettings app I am unsure of what I now need to enter.
Does anyone know of a way to get manage.py (or something else) to output the SQL for these tables and their contents?
Thanks.
Having done a bit more digging, I found these:
Fixing the auth_permission table after renaming a model in Django and manage.py sql command for django models - Django.
These output the tables, but not the data:
python manage.py sql auth
python manage.py sql admin
But this gets a lot closer. In the end I managed it with the following:
from django.contrib.auth.management import create_permissions
from django.db.models import get_apps
for app in get_apps():
create_permissions(app, None, 2)
from django.contrib.contenttypes.management import update_all_contenttypes
update_all_contenttypes(interactive=True)
This adds all the permissions and then all the content types which are needed. interactive=True means that it asks you if you want to remove stale content types.
#hajamie solution works for older supported version, taking a hint, below is what worked for me!
django = 1.9.7
from django.contrib.auth.management import create_permissions
from django.contrib.auth.models import Permission
from django.apps import apps
def fix_user_permission():
"""
run this method via shell whenever any amendments in any of the tables is made
"""
print "fixing user permissions"
# delete pre-existing user permission
Permission.objects.all().delete()
apps.models_module = True
create_permissions(apps, verbosity=0)
apps.models_module = None
print "process completed - fixed user permissions"
The easiest solution I found is to install Django Extensions, add it to settings.INSTALLED_APPS and run:
manage.py update_permissions
