Need help with a modelChoiceField

[Bobby Roberts]

ok here's my form:

class ParseFileChoiceField (forms.ModelChoiceField):
def label_from_instance (self,obj):
return obj.ProcessFile

class FrmParser (forms.Form):
parsefile = ParseFileChoiceField(queryset=Upload.objects.filter
(numrecs__exact=0),empty_label='Choose',required=True,widget=forms.Select
())


The result is this:

<select name="parsefile" id="id_parsefile">
<option value="" selected="selected">Choose</option>
<option value="3">Upload object</option>
</select>

I need the visible text to be the ProcessFile value rather than Upload
Object


any ideas?

label_from_instance was added after that version. For now the only
thing you can do is to define __unicode__ on the Upload model, and
that will provide the value that is displayed.

No __unicode__ in 0.96.  Probably __str__.
