如何在 Django 中显示今天、昨天和最近 7 天的数据？

Question

我想显示 today、yesterday 和最后 7 days 的数据，请告诉我该怎么做。

我正在尝试这个....但它只显示最近 7 天的数据，但我想根据 today、[=13= 在我的 HTML 文件中显示数据] 和 last 7 days 这是我的 views.py 文件..

def myview(request):
  datas= Mymodel.objects.filter(created_on_gte=datetime.now()- 
  timedelta(days=7)).count()
  context= {'datas':datas}
  return render(request, 'test.html', context}

这是我的 test.html 文件，我在其中显示数据...

<p>{{datas}} today</p>
<p>{{datas}} Yesterday</p>
<p>{{datas}} Last 7 Days</p>

Answer 1

此查询将给出聚合结果并在模板中适当使用它

from django.utils import timezone
from datetime import timedelta
from django.db import models

now = timezone.now()
Mymodel.objects.aggregate(
    today=models.Count('id', filter=models.Q(created_on__date=now.date())),
    yesterday=models.Count('id', filter=models.Q(created_on__date__gte=(now - timedelta(hours=24)).date())),
    last_7_day=models.Count('id', filter=models.Q(created_on__date__gte=(now - timedelta(days=7)).date())),
)

更新

from django.utils import timezone
from datetime import timedelta


def myview(request):
    now = timezone.now()
    <b>result =</b> Mymodel.objects.aggregate(
        total=models.Count('id'),
        today=models.Count('id', filter=models.Q(created_on__date=now.date())),
        yesterday=models.Count('id', filter=models.Q(created_on__date__gte=(now - timedelta(hours=24)).date())),
        last_7_day=models.Count('id', filter=models.Q(created_on__date__gte=(now - timedelta(days=7)).date())),
    )
    <b>context = {'result': result}</b>
    return render(request, 'test.html', <b>context</b>)

然后在您的模板中，

<p>{{ result.today }} today</p>
<p>{{ result.yesterday }} Yesterday</p>
<p>{{ result.last_7_day }} Last 7 Days</p>

Answer 2

尝试这样的事情：

from django.shortcuts import render

def days(request):
    
    week = Mymodel.objects.filter(created_on_gte=datetime.now()-timedelta(days=7)).count()
    yesterday = Mymodel.objects.filter(created_on_gte=datetime.now()-timedelta(days=1)).count()
    today = Mymodel.objects.filter(created_on_gte=datetime.now())

    context = {
        'week': week,
        'yesterday' : yesterday,
        'today' : today,
    }
return render(request, 'days.html', context)

.html

<p>{{today}} today</p>
<p>{{yesterday}} Yesterday</p>
<p>{{week}} Last 7 Days</p>
