After some digging around, it looks like the newforms-admin branch
does not allow widget declarations within the model class itself.
However, adding a custom widget is quite easy.
In the branch, almost all of the admin app functionality has been
moved out of the inner Admin class and into a separate class called
ModelAdmin. If you want to customize the admin app's behavior, simply
subclass ModelAdmin and override the default functionality.
For example, look at this sample ModelAdmin subclass:
-----
from django.contrib import admin
[...]
class ProfileOptions(admin.ModelAdmin):
list_display = ('display_name', 'headline','setup_date')
filter_horizontal = ('techniques', 'products', 'setup')
fields = (('Administrative Settings',{'fields':
('subscriber','active')}),('Contact Information',{'fields':
('phone_numbers','im_accounts','zip_code')}),('Photos',{'fields':
('primary_photo','secondary_photos','private_photos')}),)
def formfield_for_dbfield(self, db_field, **kwargs):
if db_field.name == 'zip_code':
return ZipCodeField(**kwargs)
else:
return
super(ProfileOptions,self).formfield_for_dbfield(db_field,
**kwargs)
def queryset(self, request):
return self.model.user_profiles.get_query_set()
adminsite.register(Profile,ProfileOptions)
----
list_display and fields are used exactly as they were in inner Admin
classes. filter_horizontal is simply a tuple of fields that will use
the javascript multiple-select filter.
The queryset() function allows you to specify which manager should be
used to obtain the change list objects.
Then there's formfield_for_dbfield(), a function that allows you to
override the default form field types that are returned for your
models' fields. In this example, the function returns a custom field
class (ZipCodeField) for any model field named "zip_code".
Alternatively, you could specify a custom widget like so:
if db_field.name == 'zip_code':
kwargs['widget'] = WIDGET
return
super(ProfileOptions,self).formfield_for_dbfield(db_field,
**kwargs)
Finally, don't forget to register your ModelAdmin subclass for the
model.

I hope this helps! If I am wrong about any of this, please post so
others don't repeat my mistakes.
