Datafile not found, datafile generation failed in confusable_homoglyphs/categories.py

I'm setting up a django project on an apache server. It is running fine on my PC under using manage.py runsslserver.
When I load onto the apache server I can run manage.py migrate and collectstatic and a number of setup programs.
BUT when I try to enter the webpage I get error message "Datafile not found, datafile generation failed" with this traceback:

I have been trying to sort this for 3 hours and cannot work it out. Any help greatly appreciated.

(I couldn't comment on the question because I don't have enough karma.)
You encountered this error because you rely on a library I wrote. It downloads some files from unicode.org whenever it gets loaded for the first time. Unfortunately I didn't expect a few use cases, for instance deploying apps with my lib as a dependency on Platforms as a Service, where dependencies would frequently get downloaded, which would also cause my lib to hit unicode.org much more frequently than I had expected.
Fortunately someone submitted a patch to the lib, fixing this issue for good. Please upgrade to confusable_homoglyphs>=3.0.0. :)

I have the same problem, and after doing some research I've discovered the source of the problem: the registration library requires confusable-homoglyphs, and confusable-homoglyphs looks for two files: categories.json and confusables.txt. If it doesn't find those files, it tries to download two files from unicode.org - Scripts.txt and confusables.txt - and generate the two json files from those. If you download those files too often, unicode.org will throttle your bandwidth and possibly even blacklist your address.
confusable-homoglyphs is hard-wired to put the files in the working directory returned by os.getcwd(), so I downloaded those files on a different computer and put them in my working directory. The Django migration was successful. I hope this works for you too!

django template errno 13

I have a problem with django template. I made new template file in pycharm and in code i think all is good. But i have errno 13 permission denied. Other templates are working fine.

i think i have permission to this folder because other templates are working.

I would recommend to go through this-
Also , the view that you uses the template are also in the same directory as other views since you said that other views are able to access their templates ?
Let me know , if this solves your problem

Maybe you are just forgetting to indicate the template path (template / app/index.html) in the views.py.

Django -- Models don't exist, but Django still loads them

Im getting a ProgrammingError when I try to delete a User object, this is wherever User.delete occurs, it even happens in the admin.
The Error
Django apparently 'thinks' that there's a relationship between auth_user and apiHandlers_cardholders which doesn't exist anywhere, the database doesn't have a column for this, and there is no models.[y nor admin.py in the app named apiHandlers , but Django expects it to, there is even a section of the Admin site devoted to it. This only started happening when I migrated from SQLite to PostGreSQL.
At the moment all the local dependencies (models, admin, forms and fields) are in an app called helpers, I'm not sure if this is efficient, but it keeps everything in one place and avoids complications.
UPDATE 0.1
No. One of the probably gonna be many updates
I used to have a problem when migrating, related to Django Rest Framework, but I eventually managed to fix it by a quick pip install to a new update of restframework, it's no longer giving me any error while making migrations and migrating.
Below is the current traceback I'm getting from the Django admin, it's basically the same in the other deletion methods.

UPDATE 0.2
I am using ./manage.py runserver (Mac) to run it, so far I haven't managed to test it with Nginx and WSGI on my server.
I am not getting a warning saying that it could affect another model, in the admin, for example, I am just getting this error immediately.

This is very likely to be because you have a stray models.pyc file somewhere. Clear out all the *.pyc files. You can try something like this if you are on linux:
find . -name '*pyc' -exec 'rm' '{}' ';'
Follow that by ./manage.py makemigrations apihandlers and then ./manage.py migrate

Python http_client error [duplicate]

I am trying to create a simple API using django rest framework. In the view i have the following code.
from django.shortcuts import render
from moviestash.models import Movie
from moviestash.serializer import MovieSerializer
from rest_framework import generics
#List all movies and add movies
class MovieList(generics.ListCreateAPIView):
queryset = Movie.objects.all()
serializer_class = MovieSerializer
#Get a movie and delete a movie
class MovieDetail(generics.RetrieveDestroyAPIView):
queryset = Movie.objects.all()
serializer_class = MovieSerializer
when i run the server and try to go to any url i get the following error.

This is very frustrating to say the least.

It looks like you are hitting issue 2969. It should work if you upgrade from Django 1.6 to 1.6.11. However, please note that 1.6 is now end of life and does not receive security fixes, so ideally you should upgrade to the latest supported version of Django or the latest LTS.

Django attribute error: 'module' object has no attribute 'is_usable'

I got the following error when calling the url in Django.
It's working before, I guess it's related with some accidental changes I made, but I have no idea what they are.
Thanks before for the help,
Robert

It looks like Django is looking for a usable template loader, but is finding something in settings.TEMPLATE_LOADERS that isn't honoring the template loader function protocol (described briefly here.)
Is it possible that one of your recent changes was to either settings.TEMPLATE_LOADERS or to a custom template loader? If the latter, your template function needs an is_usable attribute, presumably set to True.
