Well, there are a couple things you could do:
for the PresupuestoAdminForm, you could do this to the CharField:
name = forms.CharField(max_length=100,
widget=forms.TextInput(attrs={'readonly': 'readonly'}))
(note the CharField is from the 'forms' package, not the 'models'....
you'll also need to remove the 'name' entry from the readonly_fields
tuple)
Alternatively, you could ignore using the custom ModelForm, and add
the 'name' field directly to the PresupuestoAdmin class. In that case
you can use the readonly_fields tuple.
I would probably go with the first choice since it will allow you to
write a custom query to populate the field in the constructor.
Example:
class StoreAdminForm(forms.ModelForm):
test = forms.CharField(max_length=100,
widget=forms.TextInput(attrs={'readonly': 'readonly'}))
def __init__(self, *args, **kwargs):
super(StoreAdminForm, self).__init__(*args, **kwargs)
if kwargs.has_key('instance'):
instance = kwargs['instance']
# do something with the instance here, like use it to
calculate something,
# then set the value on the 'test' field using
self.fields['test']
class Meta:
model = Store
Good luck!
