python - 按字母顺序排序 Django models.py : refering to a model defined below

Question

快速提问，

我试图清理我的 models.py，它有点到处都是；我认为按字母顺序排列它们会很聪明......

问题 某些模型引用了其他模型(通过外键)，这些模型现在在文件中下面定义。

我确信这是一个简单的解决方法，我应该做什么？

from django.db import models


class Craft(models.Model):
    subdpt = models.ForeignKey(Subdepartment, on_delete=models.CASCADE)
    #### UNDEFINED NAME SUBDEPARTMENT ###

    title = models.CharField(max_length = 200)
    description = models.CharField(max_length = 200, blank = True)

    def __str__(self):
        return self.title

class Subdepartment(models.Model):
    subdpt_name = models.CharField(max_length=200)

    def __str__(self):
        return self.subdpt_name

    class Meta:
        permissions = (
            ("can_add", "Can add items in app"),
            ("can_edit", "Can edit items in app"),
        )

您始终可以将相关模型名称​​指定为字符串:

subdpt = models.ForeignKey('Subdepartment', on_delete=models.CASCADE)
