Getting to manytomany objects from a form in the view, before saving to the database

(FYI - this is also on stackoverflow, awaiting answers)

For the following models: -

class Item(models.Model):
name = models.CharField(max_length=150)
value = models.DecimalField(max_digits=12,decimal_places=2)

class Organization(models.Model):
name = models.CharField(max_length=150)
items = models.ManyToManyField(Item, through='Customizable')

class Customizable(models.Model):
organization = models.ForeignKey(Organization)
item = models.ForeignKey (Item)
value = models.DecimalField(max_digits=12,decimal_places=2)

With the following form: -

class AssignItemsForm(forms.ModelForm):
items =
forms.ModelMultipleChoiceField(queryset=Item.objects.all(),required=False,widget=forms.CheckboxSelectMultiple)
class Meta:
model = Organization
exclude = ('name',)

How would I access the individual items that were checked after
form.is_valid and after form.save(commit=False)
in the view?

Regards,
CM.
