I'm implementing haystack with the whoosh search engine. When I run 'rebuild_index' I get the following error in my terminal.
File "/home/dilts/installingDJANGO/ENV/lib/python3.5/site-packages/django/template/loader.py", line 74, in select_template
raise TemplateDoesNotExist(', '.join(template_name_list), chain=chain)
django.template.exceptions.TemplateDoesNotExist: search/indexes/submit_app/incident_text.txt
And this error in my browser.
reduce() of empty sequence with no initial value
incidents = SearchQuerySet().autocomplete(content_auto=request.POST.get(title, ''))
return clone.filter(six.moves.reduce(operator.__and__, query_bits))
My generic file structure looks like the following...
project
|--------submit_app
|--------search_app (uses a submit_app model called Incident)
|--------templates (where I put search/indexes/search_app/incident_text.txt)
From what I've read online, I believed my structure was correct, but from the error, I'm not so sure anymore. I feel like there might be some confusion with the shared model, but I don't know.

if request.method == 'POST': # If the form has been submitted...
form = IncidentsSearchForm(request.POST) # A form bound to the POST data
if form.is_valid(): # All validation rules pass
title = form.cleaned_data['title']
## this piece isn't working at I had hoped
incidents = SearchQuerySet().autocomplete(content_auto=request.POST.get(title, ''))
else:
form = IncidentsSearchForm() # An unbound form
title = ''
incidents = ''
return render(request, 'search.html',
