hi @q0w, good point, but it would probably be better to copy that missing method into this class.

the same as in the other views:

    def _get_schema_url(self, request):
        schema_url = self.url or get_relative_url(reverse(self.url_name, request=request))
        return set_query_parameters(
            url=schema_url,
            lang=request.GET.get('lang'),
            version=request.GET.get('version')
        )

[q0w]

@tfranzel updated.
Rapidoc view also does not have this method. Should it be updated too?

[tfranzel]

sure, why not. You can update this PR if you like or open an new one.

[q0w]

Done.
