I've been using the following for something similar:
class PlainText(forms.HiddenInput):
def render(self, name, value, attrs=None):
return u'%s%s' % (forms.HiddenInput.render(self, name, value,
attrs), value)
def myobject_formfield_callback(field, **kwargs):
if field.name in ('hostname', 'ipaddress'):
kwargs['widget'] = PlainText()
return field.formfield(**kwargs)
else:
return field.formfield(**kwargs)
def myview(request):
myobject = get_object_from_somewhere()
initial = myobject.__dict__
FormClass = forms.form_for_instance(myobject,
formfield_callback=myobject_formfield_callback)
form = FormClass(initial=initial)
...
In my example I just want certain fields to show as text. If you want
that for all of them change the formfield_callback to always change the
widget.
If you only want the plain value without a hidden field change the
PlainText.render method accordingly.
Works for me.
