Django: where is the code that prints the "+" icon close to a foreign key?

Question

I cannot find which part of code print the "+" that is close to every foreign key field.

In fieldset.html there is only the call to {{ field.field }}, but in the file django/forms/widgets.py the code that prints the select, doesn't contain that code, so I suppose that there is a piece of code that manage the foreign key: where is it?

Thanks, Giovanni

Assuming you are referring to the admin interface, you should look for it in django/contrib/admin/widgets.py

The class name is RelatedFieldWidgetWrapper
