    copied!<p>I've got a form that renders a choicefield widget with a total of 3 choice values: 0, 6, 19 (these are of type "Decimal').</p> <p>When editing an object via a modelform that has the value 6 or 19 the widget has selected the proper one when rendered, but when the object is stored with the value "Decimal('0') it has selected the empty_label (which was added manually, since the list is not populated from a model when adding new objects)</p> <p>Populator:</p> <pre><code>taxlevels = [('', u'---'),] taxlevels += Metadata.objects.values_list('value', 'display'). \ filter(attribute__startswith='TAX').order_by('attribute') </code></pre> <p>Need I subclass the render method to do this?</p> <p>Thanx!</p> <p>EDIT: Added code snippets (didn't wanna spam ;)</p> <p>The form:</p> <pre><code>class ProductForm(forms.ModelForm): """ Product Model field specifications for new/edit. """ class Meta: model = Product def clean(self): cleaned_data = self.cleaned_data if cleaned_data.get('tax_level') == '--': msg = _('Choose a VAT percentage.') self._errors['tax_level'] = ErrorList([msg]) return cleaned_data description = forms.CharField( label = _('Notes'), help_text = _('Max. 100 characters'), max_length = 100, widget = forms.Textarea(attrs = {'rows': 2, 'cols': 40, 'maxlength': 100} ), required = False, ) # -- snip -- btwlevels = [('', u'---'),] btwlevels += Metadata.objects.values_list('value', 'display'). \ filter(attribute__startswith='BTW').order_by('attribute') tax_level = forms.ChoiceField( label = _('VAT'), choices = btwlevels, required = True, ) </code></pre> <p>The Model:</p> <pre><code>class Product(models.Model): """ Product Model """ objects=UserFilteredManager() owner = models.ForeignKey(User, editable=False) order = models.ForeignKey(Order, editable=False) name = models.CharField(_('Name'), max_length=50) description = models.CharField(_('Notes'), max_length=100) amount = models.DecimalField(_('Amount'), max_digits=10, decimal_places=2) unit_price = models.DecimalField(_('Unit price'), max_digits=10, decimal_places=2) tax_level = models.DecimalField(_('Tax'), max_digits=3, decimal_places=1) </code></pre> <p>hope this helps, I'll check the TypedChoiceField in the meantime.</p> <p>Thanx again.</p>
