Question

我在models.py中注册了类别管理员。我通过ForenKey在Post模型中添加了该模型。但是，当我登录到管理控制台时，看不到我的类别，我只看到类别对象（1），类别对象（2）等。我将为您提供打印屏幕和代码。

如果是日本厨房或其他任何类别（即厨师的即时博客），我看到类别对象，即我在打印屏幕上突出显示的对象。我认为这没什么大不了的，但是我在django上工作了很长一段时间，所以我忘了很多东西。你能发现一个错误吗？

谢谢大家

    def save(self, *args, **kwargs):
        self.slug = slugify(self.title)
        super(Post, self).save(*args, **kwargs)

    def get_absolute_url(self):
        return reverse('detail', kwargs={'slug': self.slug})

    def __str__(self):
        return self.title

这是admin.py

from .models import Post, Category
from django.forms import ModelForm
from django.contrib.admin import ModelAdmin
from suit_ckeditor.widgets import CKEditorWidget


class PostForm(ModelForm):
    class Meta:
        widgets = {
            'name': CKEditorWidget(editor_options={'startupFocus': True})
        }


class CategoryAdmin(admin.ModelAdmin):
    list_display = ('name', 'slug')
    prepopulated_fields = {'slug': ('name',)}


admin.site.register(Category, CategoryAdmin)


class PostAdmin(admin.ModelAdmin):
    form = PostForm
    list_display = ['title', 'slug', 'date_posted', 'author']
    list_filter = ['title', 'date_posted']

    prepopulated_fields = {'slug': ('title',)}


admin.site.register(Post, PostAdmin)

您需要在模型中覆盖__str__方法，以处理要在管理员身上显示的内容。

class Category(models.Model):
    name = models.CharField(max_length=150)
    slug = models.SlugField(max_length=150)

    class Meta:
        ordering = ('name',)
        verbose_name = 'catergory'
        verbose_name_plural = 'catergories'

    def __str__(self):
        return self.name

我看不到Cathegory列表管理员，该如何解决
