python - 子目录未显示在 django 管理页面中

Question

我正在创建一个 Django 应用程序，该应用程序的目录是子目录的父目录，并且产品将沿着子目录映射。我在下面发布我的代码，请帮忙。

from django.db import models
from datetime import datetime
from django.forms import ModelForm
from django.contrib.auth.models import User

# Create your models here.

class Catalog(models.Model):
    name = models.CharField(max_length=300)
    slug = models.SlugField(max_length=150)
    publisher = models.CharField(max_length=300, blank=True)
    description = models.TextField()
    pub_date = models.DateTimeField(default=datetime.now)

    def __unicode__(self):
            return self.name

class SubCatalog(models.Model):
    catalog = models.ForeignKey(Catalog)
    name = models.CharField(max_length=300)
    slug = models.SlugField(max_length=150)
    description = models.TextField()
    pub_date = models.DateTimeField(default=datetime.now)

    def __unicode__(self):
            return self.name            

class Product(models.Model):
    catalog = models.ForeignKey(Catalog)
    subcatalog = models.ForeignKey(SubCatalog)
    name = models.CharField(max_length=300)
    slug = models.SlugField(max_length=150)
    description = models.TextField()
    photo = models.FileField(upload_to='product_photo', blank=True)
    manufacturer = models.CharField(max_length=300, blank=True)
    price_in_ksh = models.DecimalField(max_digits=6, decimal_places=0)

    def __unicode__(self):
        return self.name

您需要在应用admin.py中注册SubCatalog:

admin.site.register(SubCatalog)
