Django - 应用程序中的冲突模型，相同的路径但不同的情况

Question

Django 1.8。 我收到此错误：

我的结构如下：

accounting
  api
  migrations
  models
    __init__.py
    account.py
    transaction.py

在 init 我有以下代码：

from .account import Account
from .transaction import Transaction, RequestedWithdrawal

我不知道 django 从哪里提出了大写事务包，我没有在我的代码中的任何地方使用它。 那么为什么会出现这个错误，以及如何解决呢？

更新。 account.py 导入

import StringIO
import csv
import logging
from decimal import Decimal

from django.conf import settings
from django.db import models
from django.db.models import Q
from django_extensions.db.models import TimeStampedModel
from notifications import notify

logger = logging.getLogger(__name__)
from accounting.tasks import notify_of_withdrawal_request_action

landlord.py 导入

import datetime
import logging
from decimal import Decimal
from collections import Counter
import random
import string
import analytics

from django.utils.timezone import utc
from django.utils.functional import cached_property
from django.utils.timezone import now
from django.db import models, transaction
from django.contrib.auth.models import User
from django_extensions.db.models import TimeStampedModel
from easy_thumbnails.fields import ThumbnailerImageField
from jsonfield import JSONField
import stripe
from rentapplication.utils import generate_random_slug
from applications.models import ApplicationTemplate
from accounting.models import Account
from reports.models import  Report, ReportSourceProfile, ReportSource
from django.core.exceptions import ValidationError
from django.contrib.auth.tokens import default_token_generator
from django.conf import settings
import base64

transaction.py 导入

import logging
from decimal import Decimal


logger = logging.getLogger(__name__)

from django.db import models
from django_fsm import FSMField, transition
from django_extensions.db.models import TimeStampedModel

from reports.models import Report

import stripe

Answer 1

我不知道为什么我会看到这个奇怪的错误消息和堆栈跟踪。但问题在于models.py和tasks.py中的循环导入。
