Override FileField widget in InlineFormset_factory?

Question

I would like to change the default upload field (FileField) in an inlineformset_factory form, to use the AdminFileWidget from django.contrib.admin.widgets. The purpose of this is to show the path of the currently uploaded file as it does in the admin forms (perhaps there is another way to do this anyway?).

I have no trouble getting the widget to work using a custom form, just cant figure out how to change the widget in an inlineformset_factory.

This will get you the Admin FileField widget instead of the standard one with 5 extra fields.

views.py

MySpecialFormset = inlineformset_factory(  MyParentModel, 
                                           MyChildModel, 
                                           form=MyChildModelForm, 
                                           extra=5)

formset = MySpecialFormset(instance=myparentmodelinstance) #add request.POST and request.FILES if used on the POST cycle

forms.py

from django.contrib.admin.widgets import AdminFileWidget

class MyChildModelForm(forms.ModelForm):

    class Meta:
        model = MyChildModel

    def __init__(self, *args, **kwargs):
        super(MyChildModelForm, self).__init__(*args, **kwargs)

        self.fields['my_file_field'].widget = AdminFileWidget()
