Question

我正在尝试从elements.models导入一个类，我需要在另一个类上作为foreignkey。问题是，我得到一个我不理解的长错误列表。没有这条线，一切都很完美。

我导入线的模型

from django.db import models
from elements.models import Region

class Character(models.Model):
    """ User characters that hold the personal game stats """
    created = models.DateTimeField(auto_now_add=True)
    alive = models.BooleanField(default=True)
    name = models.CharField(max_length=63, unique=True)
    xp = models.IntegerField(default=0)
    region = models.ForeignKey(Region)
    alliance = models.ForeignKey('Alliance', null=True)
    credit = models.IntegerField(default=0)
    bullets = models.IntegerField(default=0)
    hitpoints = models.IntegerField()
    accuracy = models.FloatField(default=0)

    def __unicode__(self):
        return self.name

elements.models Region class：

class Region(models.Model):
    """ type of booze and their base price """
    name = models.CharField(max_length=31, unique=True)
    alliance_slots = models.IntegerField()

    def __unicode__(self):
        return self.name

现在，当我尝试同步数据库时，我得到以下错误列表

任何想法是什么原因造成的？

Answer 1

您可能正在进行循环导入。在导入包含Region类的models.py文件中的Character类时，您将导入包含Character类的models.py文件中的Region类。

尝试用此

替换您的Character类

from django.db import models

class Character(models.Model):
""" User characters that hold the personal game stats """
created = models.DateTimeField(auto_now_add=True)
alive = models.BooleanField(default=True)
name = models.CharField(max_length=63, unique=True)
xp = models.IntegerField(default=0)
region = models.ForeignKey('elements.Region')
alliance = models.ForeignKey('Alliance', null=True)
credit = models.IntegerField(default=0)
bullets = models.IntegerField(default=0)
hitpoints = models.IntegerField()
accuracy = models.FloatField(default=0)

def __unicode__(self):
    return self.name

从模型导入类时出现django错误
