SQLalchemy merge two queries from same table - sqlalchemy

Question

I need to query the total sales & guest for each Store for yesterday and the same day last year with the goal to be able to display in a table using jinja2.
I currently have two queries with a Union...
this_year = db.session.query(Sales.name,
func.sum(Sales.sales).label('total_sales'),
func.sum(Sales.guests).label('total_guests')
).filter(Sales.date >= start_day,
Sales.date <= end_day
).group_by(Sales.name)
last_year = db.session.query(Sales.name,
func.sum(Sales.sales).label('total_sales'),
func.sum(Sales.guests).label('total_guests')
).filter(Sales.date >= start_day_ly,
Sales.date <= end_day_ly
).group_by(Sales.name)
daily_table = this_year.union(last_year).all()
... but it gives me a list like so:
STORE 1, SALES, GUESTS
STORE 1, SALES_LY, GUESTS_LY
STORE 2, SALES, GUESTS
STORE 2, SALES_LY, GUESTS_LY
ETC,,
what i want is:
STORE 1, SALES, SALES_LY, GUESTS, GUESTS_LY
STORE 2, SALES, SALES_LY, GUESTS, GUESTS_LY
class Sales(db.Model):
__tablename__ = 'Sales'
id = db.Column(db.Integer, primary_key=True)
date = db.Column(db.String(64))
daypart = db.Column(db.String(64))
name = db.Column(db.String(64))
sales = db.Column(db.Integer)
guests = db.Column(db.Integer)
data:
|id|date|daypart|name|sales|guests|
|-----|-----|-----|-----|-----|-----|
|14896| 2021-11-22| Dinner| STORE 1| 11250.05| 288|
|14897| 2021-11-22| Lunch| STORE 1| 9250.25| 157|
|14898| 2021-11-22| Dinner| STORE 2| 5764.95| 169|
|14899| 2021-11-22| Lunch| STORE 2| 5856.25| 168|
|14900| 2021-11-22| Dinner| STORE 3| 9186.7| 320|
|14901| 2021-11-22| Lunch| STORE 3| 7521.0| 175|
This data goes back several years.
I looked at GROUP_BY, SUBQUERY, CASE, JOIN but have not found a solution that works.

Answer 1

you have to use with_entities, and use and_
this_year = db.session.query(Sales)
.filter(and_(Sales.date >= start_day, Sales.date <= end_day))
.with_entities(
Sales.name.label('name'),
func.sum(Sales.sales).label('total_sales'),
func.sum(Sales.guests).label('total_guests')
)
.group_by(Sales.name)
last_year = db.session.query(Sales)
.filter(and_(Sales.date >= start_day_ly,Sales.date <= end_day_ly))
.with_entities(
Sales.name.label('name'),
func.sum(Sales.sales).label('total_sales'),
func.sum(Sales.guests).label('total_guests')
)
.group_by(Sales.name)
daily_table = this_year.union(last_year).all()
