consonance | WhatsApp 's handshake implementation using Noise Protocol

I've written a plugin which writes JSON output to a file in the _data directory:

I'm trying to write a plugin for my Jekyll site which writes a sorted JSON response to a data file, but I'm having trouble dealing with the limit of items in the response. The basic response looks like this:

I need to expand the div elements while click on a link and collapse it using Angular.js. I am providing my code below.

I am in Django HTTP error codes hell. Would be great if an expert can help me out of my misconfiguration.

My Django project runs with nginx as a reverse proxy coupled to a gunicorn application server.

Requirement:

I want a custom Page not found template to render (i.e. 404) when a url pattern is entered that doesn't exist in my urls.py. Sounds simple enough, and is well documented.

I have already gone ahead and implemented this.

The Problem:

Assume example.com is my live project.

1) If I try to access https://example.com/asdfasdf (i.e. unmatched, random gibberish) on my production server, it displays the 500 template instead of 404.

2) Next, if I try to curl the said url pattern via curl -I https://example.com/asdfasdf/, I see 200 OK instead of 404 or 500. Wth?

3) Moreover, if I try the same behavior with Debug = True on localhost, 404 is returned correctly (both template and HTTP error code are in consonance).

These 3 behaviors are quite perplexing.

My configuration:

I created error_views.py and inserted it in the folder where I keep my regular views.py. This error file contains:

I'd like to generate all consonances of a given string.

Consonance is a stylistic literary device identified by the repetition of identical or similar consonants in neighboring words whose vowel sounds are different. (Wikipedia)

A consonant is a letter of an alphabet that denotes a consonant sound. The following table assimilates groups of English consonants, taking the following conveniences to keep things simple(istic):

1. It ignores diagraphs ("sh", "ch", "th", etc.).
2. It ignores vowels.
3. It ignores "h", "y", "w", "x".
4. It assumes that a given letter can only be a member of one consonants group. Thus, "c" is (randomly) put together with "s" and "z", and "g" with "j".

Let's also assume that an input that conforms to cases 2 & 3 is allowed and should simply be ignored. However, an input is invalid if it either conforms to case 1, or it breaks case 4 (see examples below).

So:
