Comment:
I can't reproduce this. I'm using Oracle 10g Express Edition,
instantclient 11.2. I tested with Python 2.5 and Python 2.6, Django trunk,
and got the following results:
{{{
In [1]: import decimal
In [2]: from ticket15766.models import *
In [3]: c = Code(grenzwert=decimal.Decimal('10.00'), id=1)
In [4]: c.save()
In [5]: e = Erfasst(code=c)
In [6]: e.save()
In [7]: Erfasst.objects.get(id=1).code.grenzwert
Out[7]: Decimal("10.00")
In [8]: Erfasst.objects.select_related().get(id=1).code.grenzwert
Out[8]: Decimal("10")
In [9]: type(Erfasst.objects.select_related().get(id=1).code.grenzwert)
Out[9]: <class 'decimal.Decimal'>
}}}
If you can provide enough info for us to reproduce it, please do so and
re-open this ticket.
Also, I notice that in my results, the value `Decimal("10")` given with
`select_related()` is strictly speaking different from `Decimal("10.00")`.
I don't have enough experience with Decimal to know if this is a material
difference in itself. If it is, then you could re-open on that basis too.
But the info to track down your exact problem would probably be useful
anyway.
