Chosen url only accepts integers as id

[jaap3]

Currently the urlpatterns generated by the ChooserViewSet only accept integers (d+) as the id parameter:

This makes it impossible to create a chooser that has UUIDs as a primary key.

Minimum code to get around this:

from django.urls import path
from generic_chooser.views import BaseChosenView, DRFChooserViewSet

class UUIDCapableChosenView(BaseChosenView):
    def get(self, request, pk):
        # needed to prevent TypeError: expected string or bytes-like object, got 'UUID'
        return super().get(request, str(pk))

class ChooserViewSet(DRFChooserViewSet):
    base_chosen_view_class = UUIDCapableChosenView

    def get_urlpatterns(self):
        urls = super().get_urlpatterns()
        urls[1] = path("<uuid:pk>/", self.chosen_view, name="chosen")
        return urls
