How to order by MapField key? "Field not found in model"

[barbeember]

Hi gang,

I'm not finding in the documentation the syntax to order by a MapField property.

In the test below, how would I order by 'field1' or 'field2'? I tried using the firestore syntax of map_field_name.key, but this doesn't seem to work.

TIA!

Test code:

class Test(Model):
    name = fo.fields.TextField()
    score_data = fo.fields.MapField(default={
        'field1': 0,
        'field2': 0
    })

test1 = Test(name='test1')
test1.save()
test1.score_data['field1'] = 100
test1.score_data['field2'] = 300
test1.upsert()

test2 = Test(name='test2')
test2.save()
test2.score_data['field1'] = 200
test2.score_data['field2'] = 200
test2.upsert()

test3 = Test(name='test3')
test3.save()
test3.score_data['field1'] = 300
test3.score_data['field2'] = 100
test3.upsert()

query = Test.collection.order('score_data.field2').fetch()

for test in query:
    field1 = test.score_data['field1']
    field2 = test.score_data['field2']
    print(f"{test.name} - field1:{field1}  field2:{field2}")

Output:

fireo.fields.errors.FieldNotFound: Field "score_data.field2" not found in model "Test"

In the Firestore UI, it works to orderBy("score_data.field1", "desc")

Fixed, update Fireo to 1.5.1
