Question

我在Django中使用rest框架。我的工作目录和项目如下所示。

运行服务器时出现错误消息

ModuleNotFoundError: No module named 'anshu.myapp'

请帮助我。

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。

settings.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',
)

urls.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)),
]

views.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

model.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

“ anshu.myapp.views import TaskViewSet”的urls文件中是无法运行服务器的问题

我正在使用：-

python = 3
django = 2.0.3
rest_framework = 3.8.2

Answer 1

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

from myapp.views import TaskViewSet

Answer 2

您可以按照@Alasdair的回答将其更改为以下代码

from myapp.views import TaskViewSet

或

from .views import TaskViewSet

另一个问题是views.py

它是viewsets.ModelViewSet，而不是viewsets.Model.ViewSet。

class TaskViewSet(viewsets.ModelViewSet):

从anshu.myapp.views导入TaskViewSet ModuleNotFoundError：没有名为“ anshu.myapp”的模块
