Allow records to be grouped by hour. Similar to the already
existing options (
day, week, month, quarter, year
). Just add the paramerter
groupby='date:hour'
like shown below.
@api.multi
def sales_per_hour(self):
daily_sales = self.env['sale.report'].read_group(
domain=[],
fields=['date', 'price_subtotal'],
groupby='date:hour')
return daily_sales
