管理文件

from django.contrib import admin

from .models import Form, ContactUs


admin.site.register(Form, ContactUs)

一开始我制作联系表格只是为了发送邮件，但后来我修改了它，因为我需要在站点管理中显示数据。

Answer 1

from django.contrib import admin
from .models import Form, ContactUs
admin.site.register(Form, ContactUs)

将您的管理文件更改为此

from django.contrib import admin

from .models import Form, ContactUs

admin.site.register(Form)
admin.site.register(ContactUs)
