python - from anshu.myapp.views import TaskViewSet ModuleNotFoundError: No module named 'anshu.myapp'

问题描述

我在 Django 中使用 rest 框架。我的工作目录和项目如下所示。

当我运行服务器时，我得到的错误是

ModuleNotFoundError: No module named 'anshu.myapp'

请帮我。

anshu
    anshu
        __init__.py
        settings.py
        urls.py
        wsgi.py
    myapp
        migrations
        __init__.py
        admin.py
        models.py
        Serializers.py
        tests.py
        urls.py
        views.py
    manage.py

这是我的设置文件。

设置.py

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'myapp',
    'rest_framework',
)

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'django.middleware.security.SecurityMiddleware',
)

网址.py

from django.conf.urls import include, url
from django.contrib import admin
from rest_framework import routers
from .views import TaskViewSet


router = routers.DefaultRouter()
router.register(r'task',TaskViewSet)

urlpatterns = [

    url(r'^',include(router.urls)),
    url(r'^admin/', include(admin.site.urls)),
]

视图.py

from .models import Task
from rest_framework import viewsets
from .Serializers import TaskSerializer


class TaskViewSet(viewsets.ModelViewSet):

    queryset = Task.objects.all().order_by('-date_created')
    serializer_class = TaskSerializer

模型.py

from django.db import models

class Task(models.Model):
    task_name=models.CharField(max_length=20)
    task_desc=models.TextField(max_length=200)
    date_created=models.DateTimeField(auto_now=True)

    def __str__(self):
        return self.task_name

在“anshu.myapp.views import TaskViewSet”的 urls 文件中是不运行服务器的问题

我在用：-

python = 3
django = 2.0.3
rest_framework = 3.8.2

解决方案

您的外部anshu目录位于 Python 路径上，因此在导入时不应包含anshu前缀myapp. 将其更改为：

from myapp.views import TaskViewSet
