django 多级分类，一个 model 搞定

代码是一个学习项目代码，觉得这种分类方式挺简便，所以分享出来了。

代码语言：javascript复制

from django.db import models

# Create your models here.


class GoodsCategory(models.Model):
    """
    商品类别
    """
    CATEGORY_TYPE = (
        (1, "一级类目"),
        (2, "二级类目"),
        (3, "三级类目"),
    )

    name = models.CharField(default="", max_length=30, verbose_name="类别名", help_text="类别名")
    code = models.CharField(default="", max_length=30, verbose_name="类别code", help_text="类别code")
    desc = models.TextField(default="", verbose_name="类别描述", help_text="类别描述")
    category_type = models.IntegerField(choices=CATEGORY_TYPE, verbose_name="类目级别", help_text="类目级别")
    parent_category = models.ForeignKey("self", null=True, blank=True, verbose_name="父类目级别", help_text="父目录",
                                        related_name="sub_cat")
    is_tab = models.BooleanField(default=False, verbose_name="是否导航", help_text="是否导航")
    add_time = models.DateTimeField(default=datetime.now, verbose_name="添加时间")

    class Meta:
        verbose_name = "商品类别"
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.name
