拥有bookingrecordsView
视图,在该视图中我提取了用户的所有保留。我添加了一个模型函数is_pending()
,该函数可获取预留实例,检查date_to
字段是否已通过,并返回一个字符串。获取预留的视图:
def bookingrecordsView(request):
rsv = Reservation.objects.filter(user=request.user)
return render(request, 'booking_history_page.html', {'rsv': rsv})
以及检查日期的功能:
class Reservation (models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE)
date_from = models.DateField(auto_now=False, auto_now_add=False, blank=False)
date_to = models.DateField(auto_now=False, auto_now_add=False, blank=False)
time_from = models.TimeField(auto_now=False, auto_now_add=False, blank=False)
time_to = models.TimeField(auto_now=False, auto_now_add=False, blank=False)
destination=models.CharField(max_length=20, blank=False, verbose_name="Where will you go")
chosen_vehicle=models.CharField(max_length = 20, blank=False, default='')
booking_time=models.DateTimeField(default = datetime.now)
garage = models.CharField(max_length = 20)
city = models.CharField(max_length = 20, default='')
area = models.CharField(max_length = 20, default='')
@property
Def is_pending(self):
if self.date_to < datetime.date.today():
return "Pending"
else:
return "Over"`
这是我的模板片段:
{% for r in rsv %}
<tr>
<td>{{ r.id }}</td>
<td>{{ r.date_from }} - {{ r.date_to }}</td>
<td>{{ r.time_from }} - {{ r.time_to }}</td>
<td>{{ r.chosen_vehicle }}</td>
<td>{{ r.garage }}</td>
<td>{{ r.destination }}</td>
<td>{{ r.is_pending }}</td>
</tr>
{% endfor %}`
现在,对于所有预订,即使是几个月前通过的预订,此状态始终返回“待处理”。
如何从Reservation
函数为每个is_pending()
实例获取正确的返回值,并将其相应地传递给模板?
