I have the following project structure:
SocialRating
- accounts
-- __init__.py
-- models.py
-- tasks.py
- instagram
-- __init__.py
-- crawler.py
- social
-- __init__.py
-- models.py # Not Django models
- celery_worker.sh
accounts/models.py contains class:
from instagram.crawler import InstagramCrawler
class SocialProfile(models.Model):
...
def collect_profile_stats(self):
crawler = InstagramCrawler()
record_data = crawler.get_profile_stats(self.account_id)
InstagramCrawler class is located in instagram/crawler.py:
from social.models import SocialUserData, SocialCommentData, SocialProfileStatsRecordData
class InstagramCrawler(object):
...
And social/models.py contains simple data classes:
#dataclass
class SocialUserData(object):
user_id: str
#dataclass
class SocialCommentData(object):
social_id: str
user: SocialUserData
text: str
#dataclass
class SocialPostStatsRecordData(object):
post_id: str
subscribers_count: int
likes_count: int
reposts_count: int
comments_count: int
post_date: str
#dataclass
class SocialProfileStatsRecordData(object):
subscribers_count: int
accounts/tasks.py:
#app.task(bind=True)
def update_profile_stats(self, social_profile_pk: int):
social_profile = SocialProfile.objects.get(pk=social_profile_pk)
logger.info(f'Updating profile stats for {social_profile}')
social_profile.collect_profile_stats()
celery_worker.sh:
#!/usr/bin/env bash
celery -A SocialRating worker -l info
So, when I run celery_worker.sh (from project's root directory) it raises:
Signal handler <bound method DjangoFixup.on_import_modules of <celery.fixups.django.DjangoFixup object at 0x106819d30>> raised: ModuleNotFoundError("No module named 'social.models'")

But when I use InstagramCrawler directly from django command, it works fine:
class Command(BaseCommand):
def handle(self, *args, **options):
self.test_account_followers_count()
def test_account_followers_count(self):
crawler = InstagramCrawler()
print(crawler.get_subscribers_count('someacc'))
Why?
It seems as though the social.models module is not being loaded when Celery is run from celery_worker.sh.
Try explicitly setting the PYTHONPATH before running celery_worker.sh. For example:
export PYTHONPATH=.; ./celery_worker.sh

thank you for reading my post.
actually my problem is that when migrating from: (wagtail==1.9.1 ; wagtail_modeltranslation==0.6.0rc2) to (wagtail==2.8 ; wagtail-modeltranslation==0.10.17)

If I disable the extension import then I can run fine. I am using three models and have written serializers and trying to make an nested API using drf_extensions.
I guess the problem is related to this issue: https://github.com/chibisov/drf-extensions/issues/294
Temporary fix for me was to uninstall and install with:
pip install -U git+git://github.com/chibisov/drf-extensions.git#8001a440c7322be26bbe2d16f3a334a8b0b5860b
Firstly, I created a class that has __init__() on it in models.py, as you can see below. And when I import it in my views.py, the vscode intellisense also shows that my class takes 4 arguments. But when I try to run the program, it shows me an error saying that the class doesn't take any arguments. Any help would be appreciated, ty.
models.py:
from django.db import models
class destination:
def __init__(self, name, desc, price, img):
self.name = name
self.desc = desc
self.price = price
self.img = img
views.py:
from django.shortcuts import render
from .models import destination
dest1 = destination('Bali', 'Nice place to visit', 1000, 'destination_1.jpg')
dest2 = destination('Mumbai', 'The city that never sleeps', 500, 'destination_2.jpg')
dest3 = destination('Sylhet', 'The city of tea', 100, 'destination_3.jpg')
dests = [dest1, dest2, dest3]
def travello(req):
return render(req, 'index.html', {'dests': dests})

Running your Code snipped like it is works for me and the code snipped doesn't really tell the problem, so I expect you import another destination at some point, that you did not provide in your snipped or is hidden behind another import. I would recommend renaming your class e.g. Destination (using upper letter is the recommended way to write class names anyways) and see if that solves your problem.

from seasons.models import Seasons
ImportError: cannot import name 'Seasons'
I randomly got this error in my recent django app. I am not sure why. The models import in other apps/files in my project. Any help is appreciated.
I believe you faced circular model import. Seems like you are importing User into seasons.model and Seasons into users.model.
If you use them as a foreign key you can set it as:
user = models.ForeignKey('users.User')
I am getting an error in Django. I saw a lot of similar questions but am not able to find a working solution. I think the error is in importing the User model. I am not able to find a solution to this. Basically, it seems that it is not able to get the User model. Please help.
