Python ModuleNotFoundError:没有名为'django_backend.todo'的模块

刚刚开始了一个新的Django Rest框架项目，我一直在导入一个视图以在url.py中查看

这是一个全新的项目，我所做的只是添加模型、视图，现在尝试添加url

File "C:\Users\Simon\Documents\GitHub\tradingjournal\django_backend\django_backend\urls.py", line 20, in <module>
    from django_backend.todo.views import TodoView
ModuleNotFoundError: No module named 'django_backend.todo'

views.py

from django.shortcuts import render

# Create your views here.
from rest_framework import viewsets

from django_backend.todo.models import Todo
from django_backend.todo.serializers import TodoSerializer


class TodoView(viewsets.ModelViewSet):
    serializer_class = TodoSerializer
    queryset = Todo.objects.all()

设置.py

我尝试将django_backend.todo.views更改为todo.views，但正如您在屏幕截图中看到的，无法识别：

---

在Django项目中，项目的目录名在代码中实际上并不重要，因此

from django_backend.todo.views import TodoView

你需要写：

from todo.views import TodoView

接下来，您会看到pycharm抱怨这不是有效的导入，而实际上它是有效的导入，可以通过实际运行项目来查看。为什么会发生这种情况？这是因为它认为您的项目根目录，即django_后端上可能有一个目录作为源根目录，因此无法解析您的导入。要解决此问题，只需通过以下步骤将其设置为源根：

右键单击项目目录，即左侧项目结构上的django_后端 选择“将目录标记为”选项 单击源根目录

---

从todo.views import到DOVIEW等。在导入中不要使用项目名称，只使用应用程序名称。@AbdulAzizBarkat检查我添加的屏幕截图。如果我使用todo.Views，则找不到视图。这只是您的IDE不知道源根在哪里，如果您实际运行不会给出错误的项目，由于您正在使用pycharm，您可以通过以下方式设置：右键单击项目目录，即左侧项目结构上的django_后端>将目录标记为>源root@AbdulAzizBarkat谢谢，这就解决了！！如果你能发布一个答案，我可以解决这个问题，并给你互联网积分

from todo.views import TodoView
