我有两个模型
用户模型和 DailyPresent 模型,用户为 DailyPresent 模型中的 foreign_key。
class DailyPresentReport(models.Model):
PRESENT = 'present'
ABSENT = 'absent'
ON_LEAVE = 'on_leave'
PRESENT_CHOICES = (
(PRESENT, 'Present'),
(ABSENT, 'Absent'),
(ON_LEAVE, 'On Leave'),
)
user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='daily_present_report')
present = models.CharField(max_length=10, choices=PRESENT_CHOICES, default=ABSENT)
punch_in = models.DateTimeField(null=True, blank=True)
punch_out = models.DateTimeField(null=True, blank=True)
date = models.DateField(null=True, blank=True)
work_time = models.DurationField(null=True, blank=True)
class Meta:
ordering = ['id']
def __str__(self):
return f'{str(self.user)}: {self.present}'
If User logs in then he is automatically made present
但是当用户没有登录时,什么也没有发生。
现在我想显示一个包含所有用户的表格,其中包含存在和不存在字段。
请帮助我..提前谢谢
