Strftime error Python

Question

我正在调用一个函数来获取司机收入的计算，但是，我不断收到此错误：

"line 396, in driver_get_revenue
monthly[month.strftime("%m")] = orders.count() * settings.DRIVER_DELIVERY_PRICE
AttributeError: 'int' object has no attribute 'strftime'"

函数是这样的：

def driver_get_revenue(request):
driver = JWTAuthentication().authenticate(request)[0].driver

#Returns the difference between date and time.
from datetime import timedelta
revenue = {}
monthly = {}
yearly = {}

today = timezone.now()
month = today.month
year = today.year

#Created a range to calculate the current weekday.
current_weekdays = [today + timedelta(days = i) for i in range(0 - today.weekday(), 7 - today.weekday())]
for day in current_weekdays:
orders = Order.objects.filter(
driver = driver,
status = Order.DELIVERED,
created_at__year = day.year,
created_at__month = day.month,
created_at__day = day.day
)
revenue[day.strftime("%A")] = orders.count() * settings.DRIVER_DELIVERY_PRICE


for day in range(0, 30):
orders = Order.objects.filter(
driver = driver,
status = Order.DELIVERED,
created_at__month = month,
created_at__day = day
)
(Line 396)  monthly[month.strftime("%m")] = orders.count() * settings.DRIVER_DELIVERY_PRICE


for month in range(0, 12):
orders = Order.objects.filter(
driver = driver,
status = Order.DELIVERED,
created_at__year = year,
created_at__month = month
)
yearly[year.strftime("%y")] = orders.count() * settings.DRIVER_DELIVERY_PRICE
return JsonResponse({"revenue": revenue,
"month": monthly,
"yearly": yearly})

我不确定我哪里出错了。我标记了第 396 行，以便您看到错误所在。任何帮助将不胜感激。

谢谢。

Answer 1

当你这样做时：month = today.month，月份变成整数。strftime函数适用于日期时间对象，而不是整数。

因此，month.strftime("%m")不起作用。

请尝试day.strftime("%m")，或者只是month，具体取决于您的要求。

相反，如果您正在寻找月份的名称，则可以这样做：

today = timezone.now()
month = today.month
month_name = today.strftime("%B") # e.g. December
...

。并在代码中使用month_name变量。
