Django管理站点获取要在html中显示的id

我只是想，如果管理员选择学生，它将获得id并显示在html模板中

管理员

@admin.register(studentDiscount)
class studentDiscount(admin.ModelAdmin):
    list_display = ('Students_Enrollment_Records', 'Discount_Type','my_url_field')
    ordering = ('Students_Enrollment_Records',)
    search_fields = ('Students_Enrollment_Records',)
    def my_url_field(self, obj):
        return format_html("<a href='https://www.school.ph/enrollmentform/?StudentID=pk'>Report</a>", obj.Discount_Type)
    my_url_field.allow_tags = False
    my_url_field.short_description = 'Report'

---

如果要在URL中使用

折扣\u Type.pk

，请使用如下格式：

返回格式\u html（“https://www.school.ph/enrollmentform/?StudentID={}报告”，对象折扣_Type.pk）

class studentDiscount(models.Model):
    Students_Enrollment_Records = models.ForeignKey(StudentsEnrollmentRecord, related_name='+',
                                                    on_delete=models.CASCADE, null=True)
    Discount_Type = models.ForeignKey(Discount, related_name='+', on_delete=models.CASCADE, null=True,blank=True)

return format_html("https://www.school.ph/enrollmentform/?StudentID={}'>Report", obj.Discount_Type.pk)
