Comment:
The admin app doesn't render hidden_widget at all, it just displays
readonly fields (using `getattr(modelinstance, fieldname)`). AFAICS
hidden_widget is only used by form previews and form wizards for holding
on to copies of fields that were entered in an earlier view.
If you are asking for a customised way to render a read-only field, then
it might be helpful to know that you can pass a callable to
readonly_fields that renders the result you want.
{{{
class Song(models.Model):
band = models.ForeignKey(Band)
title = CustomModelField(max_length=100)
def rendertitle(self):
return "A custom rendering of %s" % self.title
class SongAdmin(admin.ModelAdmin):
exclude = ('title',)
readonly_fields = ('rendertitle', )
}}}
