问题

当我尝试运行“python manage.py runserver”时，我收到了这个错误：

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

    import settings.py
ModuleNotFoundError: No module named 'settings'

这是我的 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)

这是我的 models.py，我只是想导入我拥有的本地 settings.py 文件。不是主要的 settings.py 文件，而是我为这个应用在本地制作的那个。

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

当我尝试运行服务器时，它告诉我它无法找到 settings.py，但 settings.py 实际上与 models.py 所在的应用程序相同。不知道为什么会这样。任何帮助将不胜感激。

【问题讨论】：

尝试使用from supplyai.ingest import settings

标签： python django

【解决方案1】：

替换

import settings

与

from django.conf import settings

【讨论】：

【解决方案2】：

"""
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

比在每个文件中你只需调用这两行：

import load_settings
settings = load_settings()

【解决方案3】：

您需要使用完整路径导入它。试试

from ingest import settings
