My django apps works correctly locally, but when I deployed it facing a uswgi seg fault for one specific route. Every others routes works correctly. Here the view:
def bunny(request): """ Filter crawler, bot and real user :param request: :return: serve rendered page to crawler / SPA to user """ ......some other codes .... path = request.get_full_path_info() if path.startswith('/news_paper'): # <<-- seg fault for this routes only in production server news_paper = utils(unquote(path[12:])) if news_paper[1] == 0: # if news paper is not found return default list return render(request, 'site_list.html') news = News.objects.filter(news_paper=news_paper[1]).order_by('-created_at')[:15] return render(request, 'news.html', {'news': news, 'title': news_paper[0]}) elif path == '/about/': return render(request, 'about.html') else: return render(request, 'site_list.html') uWsgi conf file:
