I have been trying to use Textfield in class but the suggestions just does not show up. Instead i receive an error in my Cmd console. This was even the case while using CharField.
Below is my code:
from django.db import models
from django.db.models import CharField
from django.db.models import Textfield
from datetime import datetime
class Posts(models.Model):
title = models.CharField(max_length=200)
body = models.TextField()
created_at = models.DateTimeField(default=datetime.now, blank=True)
This is the error i get in my CMD:

Actually you don't need to import the fields separately, you could use the django.db.models that you have imported earlier.
And the error is produced because you should use TextField with a capital F

I have split the Django models into multiple model files following the follow file tree structure,
+-api(app)-+
+-__init__.py
+-models -+
|
+-__init__.py
+-model1.py
+-model2.py
+-model3.py
+-serializers-+
|
+-__init__.py
+- model1_serializer.py
+-views
+-apps.py
...
my __init__.py in models looks like,
from .model1 import *
from .model2 import *
and serializer __init__.py files look like this,
from .model1_serializer import MBTITypeSerializer
I have splitter views files and serializer files. When I try to import models some of them imports without any problem, but some imports not working. I have observed if I change the import order in __init__.py file the working imports change. This is how I tried to import models,
in serializers
from api.models import MBTIType

Here is the error trace,

Hoping any guidance to solve the issue.
check your model2.py, you have there on line 5 from api.serializers import serilizer1
But you don't need to have serializer1 in models.

It's frustrating that I'm a beginner and a rookie, I can't fix it.
And I didn't find the answer on the Internet, I can only try to come here and ask for your help
version:
Django: 3.2.10
drf : 3.11
redis: 3.0.2 （windows release）
my settings:
CACHES = {
'default':{
'BACKEND': 'django_redis.cache.RedisCache',
'LOCATION': 'redis://127.0.0.1:6379/0',## if redis server has passwd，
# "LOCATION": "password#redis://127. 0.0.1:6379",
'OPTIONS': {
'CLIENT_CLASS': 'django_redis.client.DefaultClient',
}
},
}
#
REST_FRAMEWORK_EXTENSIONS = {
'DEFAULT_CACHE_KEY_FUNC':
'rest_framework_extensions.utils.default_cache_key_func'
}
#views.py Like this：
from Users.serializers import UserAddrModelSerializer
from rest_framework_extensions.cache.decorators import cache_response
class Cache_test(APIView,):
permission_classes = []
throttle_classes = (AnonRateThrottle, UserRateThrottle)
#cache_response(timeout=60)
def get(self, request, *args, **kwargs):
obj = UserAddress.objects.all()
result = UserAddrModelSerializer(instance=obj, many=True).data
return Response(result)
This particular error is caused by drf-extensions not being compatible yet with Django 3.1+. (drf-extensions is one of the dependencies of your app; also, you say you're using 3.2.10, but 3.2 is still under development; the latest released version as of writing is 3.1.1) I've found a commit to the drf-extensions project on GitHub solving this issue, but that has not found its way yet to a release.
Some of your options:
Check if you really need the dependency, and if not, uninstall it. Depending on your caching needs, simply using Django's built-in caching framework might suffice.
Incorporate the fix in that commit that I linked into your installation of that dependency (i.e. patch your library locally).
Downgrade your Django installation in the meantime to version 3.0 (as a last resort).
I'm trying to make a model that needs a relationship of one to one with a feedstock that is used by a plenty of formulas. This is my code:
from django.db import models
from dashboard.models import Formulas, Feedstock
class FeedstockFormulas(models.Model):
ratio = models.FloatField()
feedstock = models.OneToOneField(Feedstock, on_delete=models.CASCADE, default="0")
formulas = models.ForeignKey(Formulas, on_delete=models.CASCADE)
This is the error I'm getting:

I can't really solve it, since the first parameter to ForeignKey is already a model...
It looks like this is a by-product of a circular import somewhere.
Try changing to

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

#dataclass

comments_count: int
post_date: str
#dataclass
class SocialProfileStatsRecordData(object):

def update_profile_stats(self, social_profile_pk: int):

logger.info(f'Updating profile stats for {social_profile}')
social_profile.collect_profile_stats()

from social.models import SocialUserData, SocialCommentData, SocialProfileStatsRecordData
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

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')
