Question

我在同一个文件夹（app）feed中有两个文件。

models.py

from django.db import models
from .managers import FeedManager

class Feed(models.Model):
    #fields for my model

managers.py

from django.db import models

from .models import Feed

class FeedManager(models.Manager):
    def get_queryset(self, *args, **kwargs):
        return super(FeedManager, self).get_queryset(*args, **kwargs)

运行服务器时出现以下错误：

      Unhandled exception in thread started by <function wrapper at 0x04064370>

    from .managers import FeedManager
  File "C:\Users\Sumit\Desktop\django\network\feed\managers.py", line 3, in <module>
    from .models import Feed
ImportError: cannot import name Feed

为什么我会收到此错误，如何解决此问题？

Answer 1

您已经介绍了一个循环导入：models模块依赖于managers模块，而models模块依赖于var DesafioTag = new HashSet<int>( desafio.Tags.Select(a => a.Id));模块。

由于无法解决依赖关系，因此无法解析任何模块。尝试重新组织您的模块。
