python - Error handling in Django REST framework - empty file returned instead of Error view -

i have piece of code in django rest framework looks following. works if request arguments valid, if specify non-valid search keyword, browser returns empty python file length of 0 bytes instead of html error code. doing wrong respect error catching?

from rest_framework.response import response rest_framework.views import apiview rest_framework.renderers import jsonrenderer, statichtmlrenderer rest_framework.exceptions import parseerror  class getdataseriesid(apiview):     renderer_classes = (jsonrenderer, statichtmlrenderer)      def get(self, request, format=none):         # check format keyword , overrule default rendering format         if 'format' in request.query_params:             request.accepted_renderer.format = request.query_params['format']         # build keyword arguments  (left out clarity)         search_dict = {'station_name':'example'}         # render query         try:             res = dataseriesidserializer(**search_dict)         except exception e:             raise parseerror("malformed rest service request.\ndetail: %s", e)         return response(res.data) 

the server error log reports psycopsg2 error wanted generate:

[tue apr 19 13:09:53 2016] [error] error when executing query select [...]  [tue apr 19 13:09:53 2016] [error] column s.station_itgd not exist  indeed error wanted generate.  

the issue thought code capture error , generate proper eror view. doesn't happen. aware catching exception not practice - first step. once response work analyze errors may occur , improve part.

in drf view, supposed return response object. could, instead of raising parseerror, rest_framework import status return response({'detail':"your error message"}, status=status.http_400_bad_request), uncatched exception return response(status=status.http_500_internal_server_error)
