Thanks Malcolm for very useful answer!
Now I can add data to any models as wants. But have small problem with
SelectField.
I have this class:
class CommonManipulator(forms.Manipulator):
def __init__(self, pk=None):
self.fields = (
forms.SelectField(field_name='region',
choices=[('','-------')] + [(o.id, o) for o in Region.objects.all()]),
[...]
)
def save(self, new_data):
t = Town(
region=new_data['region'],
[...]
)
And when I save form, got this error:
Invalid value: 'region' should be a <class
'serp2.apps.common.models.Region'> instance, not a <type 'str'> Request
Method: POST Request URL: http://localhost:8000/common/add_town/
Exception Type: TypeError
Exception Value: Invalid value: 'region' should be a instance,
not a
Exception Location:/home/greg/www/django_src/django/db/models/base.py in
__init__,
line 102
What can it be?
