SQLAlchemy filter by dict of lists

Question

Trying to make a query in flask_sqlalchemy. I want to filter using a dict of lists and using ORM not a query string. Still new to SQLAlchemy so any help would be appreciated.

I know I can do:

filter = {
'name': 'apple'
, 'age': 14
}

Items.query.filter(**filter).all()

Which translates to:

SELECT * FROM items WHERE name = 'apple' AND age = 14;

---

But I want:

filter = {
'name': ['apple', 'pear']
, 'age': [14, 15, 21]
}

To be:

SELECT * FROM items WHERE name IN ('apple', 'pear') AND age IN (14, 15, 21);

Answer 1

This seems to do the trick:

filter = {
    'name': ['apple', 'pear']
    , 'age': [14, 15, 21]
}    

items = Item.query

for field in query:
    items = items.filter(getattr(Item, field).in_(query[field]))

items = items.all()
