Question

I\'ve added a method highlight_link to my model\'s admin.py class:

    list_display = (\'start_time\

This is edited version of @user27478 answer, which uses thread-local vars:

class RadioGridAdmin(admin.ModelAdmin):
    def __init__(self, model, admin_site):
        super().__init__(model, admin_site)
        self._request_local = threading.local()

    def changelist_view(self, request, extra_context=None):
        self._request_local.request = request
        return super().changelist_view(request, extra_context)

    @property
    def _request(self):
        return self._request_local.request

    def example_highlight_link(self, obj):
        changelist = self.get_changelist_instance(self._request)
        url = changelist.get_query_string(new_params={'key1': 1})
