I've encountered the same problem today. Here is my solution. This is example of read-only field for the ForeignKey value:

class MySelect(forms.Select):
    def render(self, name, value, attrs=None, choices=()):
        s = Site.objects.get(id=value)
        return s.name

class UserProfileInlineForm(forms.ModelForm):
    site = forms.ModelChoiceField(queryset=Site.objects.all(), widget=MySelect)

class UserProfileInline(admin.StackedInline):
    model = UserProfile
    form = UserProfileInlineForm
