Question

在进行第一个认真的django项目（进展非常顺利）时，我遇到了一个管理站点的愚蠢问题，无法在任何地方找到答案。我的管理站点不再显示任何模型（以前没有），甚至没有显示“用户和组”。

我从设置和URL中取出了自己的模块等，所以它们现在看起来像这样：

settings.py：

admin.py（尽管在settings.py中未将其用作模块注释）：

    from django.contrib import admin
from .models import Category, KnowledgeTree


class KnowledgeTreeAdmin(admin.ModelAdmin):
    list_display = ('id', 'level', 'index', 'treestring', 'name', 'category', 'description', 'parent',)

class CategoryAdmin(admin.ModelAdmin):
    list_display = ('id', 'index', 'name', 'description')
    list_editable = ('name','index')
    admin_order_field = ('index',)


admin.site.register(Category, CategoryAdmin)
admin.site.register(KnowledgeTree, KnowledgeTreeAdmin)

Django Admin不显示任何模型，甚至不显示Core（用户/组）
