Well I experimented with your tips Daniel, and put this in my forms
file:
class SurveyForm(forms.ModelForm):
name = forms.CharField(max_length=50, widget=forms.TextInput(attrs=
{'size':'50'}))
class Meta:
model = Survey
And it works. I assume I just add the ones above that I want to change
the defaults on? Much DRYer - ah
Thank You
