Tim,
I found this in the Django source code on Github searching for
'formfield_overrides'. It is in a test module testing formfield_overrides
functionality. I'm assuming you imported TextInput from forms? This should
work to change your *admin* display. Are trying to change your Admin panel
form or a form going out to the user?
class BandAdmin(admin.ModelAdmin):
formfield_overrides = {
CharField: {'widget': forms.TextInput(attrs={'size': '10'})}
}
Regards,
Joe
