요새 장고(django)로 개발을 진행하여 서비스 런칭을 준비중이다.

그런데 이게.. 참.. php만 하다가 python을 하려니 아직 익숙치않아 헷갈리는 부분이 존재.

그래서 개인적인 참고를 하기위해 정리한다.

프록시 모델

from django.contrib.auth.models import User, Group, UserManager

class ProxyUserManager(UserManager):
    def get_queryset(self):
        return super().get_queryset().filter(groups__name__in=['그룹명'])

class ProxyUser(User):
    objects = ProxyUserManager()

    class Meta:
        proxy = True
        verbose_name = '프록시 유저그룹'
        verbose_name_plural = '프록시 유저그룹'
        ordering = ('first_name', 'username')

모델명을 str로 표기할때

class Smodel(models.Model):
    name = models.CharField(max_length=30, verbose_name='S모델 이름')

    def __str__(self):
        return self.name

    class Meta:
        verbose_name = 'S모델'
        verbose_name_plural = 'S모델'
        ordering = ('id',)
