Question

我有一个称为“统计”的模型。从视图中，我创建了一个ListView使其显示在模板上。现在我的问题是我只想看到today's == date_expiry。如何使用ListView来做到这一点？

models.py

class Statistics(models.Model):
    site = models.CharField(max_length=264)
    name = models.CharField(max_length=264, blank=True)
    mac_add = models.CharField(max_length=264)
    minutes_used = models.CharField(max_length=265)
    date = models.DateTimeField(auto_now=True, blank=True)
    date_expiry = models.DateTimeField()

    def __str__(self):
        return self.name

views.py

class DisplayStats(ListView):
    model = Statistics

    ordering = ['date']

html

<table class="table">
     <tr>
         <th>Site</th>
         <th>Name</th>
         <th>Mac ID</th>
         <th>Hours</th>
         <th>Date</th>
         <th>Date Expired</th>
     </tr>
     {% for clients in object_list %}
        <tr>
            <td>{{ clients.site }}</td>
            <td>{{ clients.name }}</td>
            <td>{{ clients.mac_add }}</td>
            <td>{{ clients.minutes_used|cut:".0" }}</td>
            <td>{{ clients.date }}</td>
            <td>{{ clients.date_expiry }}</td>
        </tr>
     {% endfor %}
</table>

Answer 1

您可以过滤它。

import datetime

class DisplayStats(ListView):
    model = Statistics

    ordering = ['date']

    def get_queryset(self):
        # python3
        queryset  = super().get_queryset()
        # if python2
        # queryset = super(DisplayStats, self).get_queryset()
        queryset.filter(date_expiry=datetime.date.today())
        return queryset

Answer 2

您可以仅过滤查询集。您可以通过两种方式做到这一点：

覆盖queryset

import datetime

class DisplayStats(ListView):

    model = Statistics
    queryset = Statistics.objects.filter(date_expiry=datetime.date.today())
        ordering = ['date']

使用get_queryset()

import datetime

class DisplayStats(ListView):

    model = Statistics
    ordering = ['date']

    def get_queryset(self):
        return Statistics.objects.filter(date_expiry=datetime.date.today())
