#23460 closed Bug (fixed)

Allow a literal `%s` to be passed through extra select

Description (last modified by Matt Robenolt)

Right now, if you try and do something like this:

Foo.objects.extra(select={'foo': "'%%s"'})

or

Foo.objects.extra(select={'foo': '"%s"'})

Ultimately add_extra raises a StopIteration while iterating over param_iter since there aren't actually any arguments to format.

It's expected to allow %%s as an escape sequence.

See: ​https://github.com/django/django/pull/3209 for patch.
