Django ModuleNotFoundError：没有名为“模型”的模块

Question

我正在 Django 中构建一个网络应用程序来购买电影票。所有处理数据库的逻辑都在“ticket_handler”应用程序中。实际网站位于“movie_site”应用程序中，我正在“ticketing_api”应用程序中构建一个restful API。

每当我尝试将某些内容从一个应用程序导入到另一个应用程序时，都会收到“ModuleNotFound”错误。这是我的目录结构：

Movie_Ticketing_Service
|- movie_server
|   |- movie_server
|   |   |- __init__.py
|   |   |- asgi.py
|   |   |- settings.py
|   |   |- urls.py
|   |   |- wsgi.py
|   |- movie_site
|   |   |- migrations
|   |   |- templates
|   |   |- __init__.py
|   |   |- admin.py
|   |   |- apps.py
|   |   |- forms.py
|   |   |- models.py
|   |   |- tests.py
|   |   |- urls.py
|   |   |- views.py
|   |- ticket_handler
|   |   |- migrations
|   |   |- __init__.py
|   |   |- admin.py
|   |   |- apps.py
|   |   |- billing_handler.py
|   |   |- mail_handler.py
|   |   |- models.py
|   |   |- tests.py
|   |   |- ticket_handler.py
|   |   |- views.py
|   |- tecketing_api
|   |   |- migrations
|   |   |- __init__.py
|   |   |- admin.py
|   |   |- apps.py
|   |   |- forms.py
|   |   |- models.py
|   |   |- tests.py
|   |   |- views.py
|   |- db.sqlite3
|   |- manage.py
|- venv

这是我在 settings.py 中安装的应用程序：

 INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'movie_site.apps.MovieSiteConfig',
    'ticket_handler.apps.TicketHandlerConfig',
    'ticketing_api.apps.TicketingApiConfig'
]

引发异常的代码是 movie_site/views.py 中的导入语句：

from django.shortcuts import render, redirect
from ticket_handler.models import Movie, Showing
from ticket_handler.ticket_handler import TicketHandler
from ticket_handler.billing_handler import BillingHandler
from forms import TicketsForm, PurchaseForm, NewUserForm
from django.contrib.auth import login
from django.contrib import messages

它给了我：ModuleNotFoundError: No module named 'models'

我最初尝试过：

from movie_server.ticket_handler.models import Movie, Showing
from movie_server.ticket_handler.ticket_handler import TicketHandler
from movie_server.ticket_handler.billing_handler import BillingHandler

PyCharm 更喜欢这样，但我知道：ModuleNotFoundError: No module named 'movie_server.ticket_handler'

对此我有点抓狂，谷歌搜索并没有为我解决这个问题。如果您需要更多信息，请告诉我！

编辑：我被要求提供回溯，所以这里是：

ModuleNotFoundError: No module named 'models'

希望对您有所帮助！

Answer 1

从您的回溯中，我注意到您忘记在模型之前添加点：

改变

from models import Showing, Ticket

到

from .models import Showing, Ticket

Answer 2

哇！它也对我有用。看来我没有在我的管理员的 import .models 中添加“点”
