Apologies for creating an issue if this is the expected behaviour (FWIW
there were no ideas on IRC):
Is the behaviour outlined in this snippet expected:
{{{#!python
# models.py
from django.db import models
class Fl(models.Model):
float = models.FloatField()
# ./manage.py shell
>>> from models import Fl
>>> a = Fl.objects.create(float=' 1.0 ')
>>> a
<Fl: Fl object>
>>> a.float
' 1.0 '
}}}
I'd have expected the FloatField to convert values to a float in the
return object as well (I can verify that the `to_python` method is being
run, because the number is saved to the database correctly.
Is the recommended way of solving this to subclass FloatField and use?
{{{
class MyFloatField(with_metaclass(models.SubBaseField,
models.FloadField)):
...
}}}
