In the 'change' page of the admin panel, if we try to edit a model linked
by ForeignKey which contains a space in the 'to_field' property, the
result is a 'not found page'.

Example:

{{{
class Media(models.Model):
author = models.ForeignKey('Author', verbose_name="Author",
on_delete=models.SET_NULL, to_field="name", default="Unknown", null=True)
}}}

In this case, if the Author.name contains a space, the generated URL to
edit this author will be:
https://domain.com/admin/web_app/author/Spaced%20Name/change/?_to_field=name&_popup=1

The result is (in french with a translation, sorry):

The strange thing is that I can't reproduce this behaviour in my local
version.

Comment:

I also cannot reproduce this issue with spaces, but it's possible with
other keys, e.g. `_40`. I believe we can close this as a duplicate of
#30386, which is due to the fact that foreign key widgets don't quote
keys.
