That would certainly make sense, and would be a sensible extension to the manually-specified fields. regards Steve -- Steve Holden+1 571 484 6266 +1 800 494 3119 Holden Web LLC http://www.holdenweb.com/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Inconsistencies/Bug in ModelForm
Yes, Malcolm. You understood it correctly. I'll probably just add a quick MY_CHOICES_2 tuple that has these "-" values until I see what the plan is.

I understood the original poster's question to be about the difference between the auto-generated version and the version when he manually specified the field. My first reaction is that he's right and it should be the same in both cases (with the "" string), but I need to think about it a bit more.

Inconsistencies/Bug in ModelForm
Submitted ticket #8663 for the following: When a ModelForm? is used to display a form for a Model, the fields defined with a choices option insert a "---" value for the first option when the form is rendered. If you override a field and manually specify the choices for a Select widget, this "---" does not appear as the first choice. # models.py from django.db import models MY_CHOICES = ( (0, 'Zero'), (1, 'One'), ) class MyModel(models.Model): my_field = models.IntegerField(choices=MY_CHOICES) # forms.py from django import forms from myapp.models import MyModel, MY_CHOICES class MyModelForm(forms.ModelForm): #my_field = forms.IntegerField(widget=forms.Select(choices=MY_CHOICES)) class Meta: model = MyModel View the HTML for the form with my_field commented out: >>> from myapp.forms import MyModelForm >>> f = MyModelForm() >>> print f My field: - Zero One Now uncomment my_field in MyModelForm?: >>> from myapp.forms import MyModelForm >>> f = MyModelForm() >>> print f My field: Zero One This value doesn't appear in the 2nd case: - SVN-8643 --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
