How to use posgresql 'interval' in Django?
4
Here is my PostgreSQL statement.
select round(sum("amount") filter(where "date">=now()-interval '12 months')/12,0) as avg_12month from "amountTab"
How to use this in Django?
I have an object called 'Devc', with attribute 'date'.
I want to get the sum of the specific data within past 12 months, not past 365 days.

You can try this to get the data within the past 12 months.
today= datetime.now()
current_month_first_day = today.replace(day = 1)
previous_month_last_day = current_month_first_day - timedelta(days = 1)
past_12_month_first_day = previous_month_last_day - timedelta(days = 360)
past_12_month_first_day = past_12_month_first_day.replace(day = 1)
past_12_month_avg = Devc.objects.filter(date__range=(past_12_month_first_day,current_month_first_day)).aggregate(Sum('amount'))['amount']

You can try this to get the data within the past 12 months.
today= datetime.now()
current_month_first_day = today.replace(day = 1)
previous_month_last_day = current_month_first_day - timedelta(days = 1)
past_12_month_first_day = previous_month_last_day - timedelta(days = 360)
past_12_month_first_day = past_12_month_first_day.replace(day = 1)
past_12_month_avg = Devc.objects.filter(date__range=(past_12_month_first_day,current_month_first_day)).aggregate(Sum('amount'))['amount']
