如何在Django中使用createsuperuser命令时添加自定义错误消息？
如何在Django中使用createsuperuser命令时添加自定义错误消息？
提问于 2019-07-08 09:26:32
我已经创建了一个自定义用户模型，我希望电子邮件和用户名是一个独特的字段。我使用电子邮件作为我的主要用户名字段。两者都是独一无二的。问题是，当我创建一个“creates疗养用户”时，如果电子邮件已经被某人接收，我就会得到一个即时错误，但是如果使用username字段，它会检查末尾的唯一条件，这会导致一个丑陋的Postgres唯一约束失败错误。我希望用户名字段被立即检查，就像电子邮件字段一样。

您可以创建自己的django命令来创建超级用户。一个示例create超级用户命令可以是：
# your_app/management/commands/create_custom_superuser.py
from django.contrib.auth import get_user_model
from django.core.management.base import BaseCommand
class Command(BaseCommand):
def handle(self, *args, **options):
if not get_user_model().objects.filter(username="admin").exists():
# you can add some logs here
get_user_model().objects.create_superuser("admin", "admin@admin.com", "admin")然后可以通过python manage.py create_custom_superuser创建超级用户。
