Django ModuleNotFoundError：没有名为“设置”的模块

Question

The Problem

When I try to run 'python manage.py runserver' I get this error:

    Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x1068ddc80>

ModuleNotFoundError: No module named 'settings'

Here is my urls.py:

from django.conf.urls import url, include
from django.contrib import admin
from rest_framework.urlpatterns import format_suffix_patterns

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^ingest/', include('ingest.urls'))
]

urlpatterns = format_suffix_patterns(urlpatterns)

Here is my models.py where I am just trying to import the local settings.py file I have. Not the main settings.py file, but the one I made locally for this app.

from sqlalchemy import create_engine, Column, Integer, String, DateTime
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.engine.url import URL

import settings

DeclarativeBase = declarative_base()

def db_connect():
    return create_engine(URL(**settings.DATABASE))

def create_data_table(engine):
    DeclarativeBase.metadata.create_all(engine)

class Data(DeclarativeBase):
    __tablename__ = 'data'

    id = Column(Integer, primary_key=True)
    shipper_name = Column('shipper_name', String)
    seller_location = Column('seller_location', String)
    buyer_location = Column('buyer_location', String)
    product_category = Column('product_category', String)
    order_created_date = Column('order_created_date', String)

    def __init__(self, id, shipper_name, seller_location, buyer_location, product_category, order_created_date):
        self.id = id
        self.shipper_name = shipper_name
        self.seller_location = seller_location
        self.buyer_location = buyer_location
        self.product_category = product_category
        self.order_created_date = order_created_date

When I try to run the server, it is telling me that it cant find settings.py, but settings.py is literally in the same app that models.py is in. Not sure why this is happening. Any help would be GREATLY appreciated.

Answer 1

Replace

import settings

with

from django.conf import settings

Answer 2

If you have a custom settings.py, please update the question with the folder structure and the filenames.

It's probably a problem with the folder structure of the python package, so basically import settings doesn't work because settings.py is not found from where the file is trying to import.

Reference

Answer 3

"""
Load Settings from django
"""
def setup_settings():
    import os
    import django

    # Connect to the Django Database
    script_path = os.path.dirname(__file__)
    os.environ['DJANGO_SETTINGS_MODULE']='<<YOUR_PROJECT>>.settings'
    django.setup()

def load_settings():

    from django.core.exceptions import ImproperlyConfigured

    try:
        from django.conf import settings as settings
        settings.BASE_DIR <<<< Try to access one your settings
    except (ImproperlyConfigured, ModuleNotFoundError) as ex:
        print("Settings not loaded yet.. Load it now.")
        setup_settings()
        from django.conf import settings as settings
        settings.BASE_DIR
        print("BASE_DIR (%s) loaded." % settings.BASE_DIR)
    except Exception as ex:
        print("Could not load settings (%s)" % ex)

    if not hasattr(settings, 'BASE_DIR'):
        print("Could not find BASE_DIR in settings! ERROR!")
        sys.exit(1)

    return settings

Than in every file you just call this two lines:

import load_settings
settings = load_settings()

Answer 4

You will need to import it using the full path. Try

from ingest import settings
