Django On Production For Post Request Throws Server Error(500) On Compute Engine

I have deployed my Django 1.10 with python 3.6 Project on Google compute engine when I have changed Debug = True in my settings.py to Debug = False it throws Server Error (500) on

Solution 1:

As discussion above from comments, you can put exception handling in code and put logger in the code. For example:

import logging


classTagView(LoginRequiredMixin, generic.CreateView):
    form_class = forms.TagForm

    defpost(self, request, *args, **kwargs):
        try:
            post_data = request.POST.copy()
            post_data.update({'user': request.user.pk})
            form = forms.TagForm(post_data)
            if form.is_valid():
                tag = form.save(commit=False)
                tag.user = request.user
                tag.email = request.user.email
                tag.save()
            else:
                return HttpResponse(form.errors, status=400)

            return HttpResponseRedirect(reverse_lazy('users:dashboard'))

        except Exception as exp:
          logging.error(exp)  # For python 3return HttpResponse(exp, status=400)

And view the error logs using log monitoring tool like this blog mentioned: https://cloud.google.com/python/monitor-and-debug/logging-application-events

*** As per discussion in the comments in the answer, the problem resides in ALLOWED_HOSTS. Setting ALLOWED_HOSTS=['*'] or Setting the IP of the Server in Allowed Host solved the issue.
