Hello Graham Dumpelton, and rest of the fellow community!
i need your competent help with this issue. I've read almost all of the
threads, but unfortunately didn't get a solution.

sys.stdout = sys.stderr
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "nano_fb_py_bot.settings")
application = get_wsgi_application()
and finally, *views.py *
user01@vkc-sandbox02:~/nano_fb_py_bot/fb_nanosemantics$ cat views.py
from django.shortcuts import render
from django.views import generic
from django.http.response import HttpResponse
from django.views.decorators.csrf import csrf_exempt

import traceback
import pymysql.cursors
import json, requests, re
import hashlib
from multiprocessing import Pool
PAGE_ACCESS_TOKEN = 'some_token'
VERIFY_TOKEN = '123456789'
# Create your views here.
class FacebookBotView(generic.View):
def get(self, request, *args, **kwargs):
if self.request.GET['hub.verify_token'] == VERIFY_TOKEN:
return HttpResponse(self.request.GET['hub.challenge'])
else:
return HttpResponse('Error, invalid token')
@method_decorator(csrf_exempt)
def dispatch(self, request, *args, **kwargs):
return generic.View.dispatch(self, request, *args, **kwargs)
When i run Django app from development web server,
python manage.py runserver 127.0.0.1:8000
everything works like a charm when i do
*curl
127.0.0.1:8000/Path_to_View/LInk?hub.verify_token=some_token&hub.challenge=some_challenge*
when i don't pass get params, i see error (and that's great!!!)
But when i try access this url served by apache - i get internal server
error 500.
And no error traceback shown in my virtualhost apache logs (please see
below).
if i simplify views.py, as below
class FacebookBotView(generic.View):
def get(self, request, *args, **kwargs):
return HttpResponse('Hello World!')
@method_decorator(csrf_exempt)
def dispatch(self, request, *args, **kwargs):
return generic.View.dispatch(self, request, *args, **kwargs)
Page accessible via apache, and i get web response.
but if i make a syntax, or ident mistake, or call some function - the error
comes back again, with no traceback.
And i mention again - none of this appears with dev. web server.
