如何以今天为截止日期获取Todo项目

Question

所以我仍在创建我的待办事项列表应用程序，我想呈现所有以今天的日期为截止日期的项目，以便提醒用户挂起的任务。

型号.py

from django.db import models
from django.contrib.auth.models import User
# Create your models here.
class ToDo(models.Model):
owner = models.ForeignKey(User, on_delete=models.CASCADE)
todo = models.CharField(max_length=50)
description = models.TextField(max_length=200, blank=True)
created = models.DateField(auto_now=True)
end = models.DateField()
start = models.DateField()
completed = models.BooleanField(default=False)
def __str__(self):
return f'{self.owner} - {self.todo}'

views.py

def index(request):
activities = ToDo.objects.all()
today = ToDo.objects.get(end=datetime.date.today)
todo = ToDo.objects.count()
complete = ToDo.objects.filter(completed=True).count()
percent = complete * 100 // todo 
if request.method == 'POST':
try:
search = request.POST.get('todo')
activities = ToDo.objects.filter(todo__icontains=search)

except:
search = request.POST.get('end')
activities = ToDo.objects.filter(end=search)
context = {
'activities' : activities,
'percent' : percent,
'today' : today,
}
return render(request, 'home.html', context)

我在视图中导入了DateTime.py

Answer 1

您就快到了！

today = ToDo.objects.get(end=datetime.date.today)

是问题所在。get((用于获取一行，您需要由filter完成的所有匹配行。您还发送函数today，而不是用today()调用它。

这样做：

today = ToDo.objects.filter(end=date.today())

Answer 2

试试

from django.utils import timezone
def index(request):
today = timezone.localtime(timezone.now())
deadline_today = ToDo.objects.filter(
end__year=today.year,
end__month=today.month,
end__day=today.day
)
context = {
...
'today' : deadline_today ,
}
