Question

这是transaction.model的代码在这里，我试图从 WalletUser.models 导入 WalletUser 模型

import uuid as uuid
from django.db import models
from walletApp.WalletUser.models import WalletUser

class Transaction(models.Model):
STATUS_TYPES = (
    ('C', 'Compleat'),
    ('S', 'Success'),
    ('I', 'Incompleat'),
    ('A', 'aborted'),
)
uuid = models.UUIDField(unique=True, default=uuid.uuid4, editable=False, db_index=True)
status = models.CharField(choices=STATUS_TYPES, default='N', max_length=3)
created_on = models.DateTimeField(auto_now_add=True, null=False)
user = models.ForeignKey(WalletUser)
amount = models.FloatField()

def __str__(self):
    return self.uuid

我收到此错误

我也尝试过 walletApp.WalletUser.models 和 WalletUser.models 都不起作用。 WalletUser.models 是直接捐赠。 PLZ帮助我卡住了

Answer 1

from WalletUser.models import WalletUser

你们很亲近！由于您的应用与基础目录在同一目录中，因此您无需指定基础目录，您只需从应用中导入模型即可。

无法导入其他应用的模型表单模型
