The following example uses an elixir class:
class MyE(Entity):
id = Field(Integer, primary_key=True)
f_1 = ManyToOne('OtherE')
f_2 = ManyToOne('OtherE')
date = Field(Date)
MyE.query.select_from(union(MyE.table.select(),
select([MyE.id, MyE.f_1.label('f_2'),
MyE.f_2.label('f_1')]))).\
order_by([MyE.date])
This produces the following SQL:
SELECT anon_1.id AS anon_1_id, anon_1.f_1 AS anon_1_f_1, anon_1.date
AS anon_1_date
FROM (
SELECT mye.id AS id, mye.f_1 AS f_1, mye.f_2 AS f_2, mye.date AS date
FROM mye UNION ALL
SELECT mye.id AS id, mye.f_2 AS f_1, mye.f_1 AS f_2, mye.date AS date
FROM mye) AS anon_1 ORDER BY anon_1.date
Which strangely omits the anon_1_f_2 column and so doesn't populate
the mapper correctly (f_2 is populated with the contents of f_1)
Is this a bug?
I've upgraded SQLAlchemy to 0.5.0rc4 and also elixir to 0.6.1 but it
still appears.
Thanks
