I cannot reproduce. Here is what I get using your exact code:
In [2]:
dbt = DAL('sqlite:memory')
In [4]:
dbt.define_table('test',
Field('x', 'float'),
Field('y', 'float', compute=lambda r: r['x'] * 2))
Out[4]:
<Table test (id,x,y)>
In [5]:
dbt.test.validate_and_insert(x=1)
Out[5]:
<Row {'errors': {}, 'id': 1L}>
In [6]:
dbt.test(1)
Out[6]:
<Row {'x': 1.0, 'id': 1L, 'y': 2.0}>
