30386	Admin foreign key widgets don't quote keys.	Joshua Goodwin	Oluwayemisi Ismail	"In django.contrib.admin.ModelAdmin, _changeform_view,  _delete_view and history_view and do unquote(object_id):

https://github.com/django/django/blob/917fd9d03fdd21538864af4b412ac30b36d99268/django/contrib/admin/options.py#L1537

However, ForeignKeyRawIdWidget and RelatedFieldWidgetWrapper create links to this view without calling quote():

Steps to reproduce:

1. Create two models: Topping with a CharField primary key, and Pizza with a ForeignKey to Topping. Register both models with the admin site.
2. Create a Topping with the primary key '_40', and a Pizza with that topping
3. In the admin site, go the the /change/ page for the Pizza, and click on the 'change' icon for the Topping foreign key, or (if using ForeignKeyRawIdWidget) the link to the Topping '_40'.
4. See message 'Topping with ID ""@"" doesn't exist. Perhaps it was deleted?'."	Bug	assigned	contrib.admin	dev	Normal				Accepted	1	0	0	1	0	0
