02. xadmin的过滤器queryset()

需求: 每个老师都只能看到自己的课程

 

# models.py
from django.contrib.auth.models import AbstractUser class UserProfile(AbstractUser): ...... class Courses: teacher = models.ForeignKey(Teacher, on_delete=models.CASCADE) class Teacher: # 由于是中途才添加的user外键,所以当前teacher表已经存在数据,此时最好设置为SET_NULL
    user=models.OneToOneField(UserProfile, null=True, blank=True, on_delete=models.SET_NULL)

 

# adminx.py
import xadmin from apps.courses.models import Courses class CoursesAdmin: list_display = ['name', 'desc', ... ] search_fields = ['name', 'desc', ... ] list_filter = ['name', ...] # 重写queryset()
    def queryset(self): # 取出当前Courses表单的所有对象
        qs = super().queryset() # 如果不是超级管理员,就对qs进行过滤
        if not self.request.user.is_superuser: # 对于OneToOne这种外键,可直接反向取user.teacher
            qs = qs.filter(teacher=self.request.user.teacher) return qs xadmin.site.register(Courses, CoursesAdmin)
