render a
custom model field when marked as readonly in the admin

It is possible to override the default widget that is used to render a
custom model field... however the hidden_widget is more difficult. The
only way appears to be on a per model basis by changing the widget in the
model admin. This can be very difficult/impractical when inheriting
models that make use of the custom field with the field set to readonly in
the model admin.
For example, a simple field that uses a custom widget:
{{{
class CustomFileWidget(forms.FileInput):
return mark_safe(u"CustomFileWidget was used: %s" %
super(CustomFileWidget, self).render(name, value, attrs))
class CustomFileFormField(forms.FileField):
def __init__(self, *args, **kwargs):
kwargs['widget'] = CustomFileWidget
super(CustomFileFormField, self).__init__(*args, **kwargs)
class CustomFileField(models.FileField):
def formfield(self, **kwargs):
return super(CustomFileField,
self).formfield(form_class=CustomFileFormField,**kwargs)
}}}
However, there does not appear to be a kwarg for hidden_widget and using
something like the following will not work:
{{{
class CustomFileFormField(forms.FileField):
hidden_widget = CustomFileWidget
widget = CustomFileWidget
class CustomFileField(models.FileField):
def formfield(self, **kwargs):
return super(CustomFileField,
self).formfield(form_class=CustomFileFormField,**kwargs)
}}}
