Objective of Trinity 3
The objective of Trinity 3 is to completely annihilate its predecessor, Trinity, in both performance and code practice.
Simply said, Trinity 3 aims to offer a completely automated way of setting up a live mysql website with python easily under 5 minutes, without the need of the end user having to install third party modules! Instead, Trinity 3 automatically installs required modules via pip, and automatically creates required database tables. Just fill out settings.py and you're allset.

Technologies and Modules used
All required modules will be automatically installed by Trinity 3. (unlike its predecessor)

• Python 3.6.1 (General code base)
• Flask (Web module for python)
• PyMysql (Database module for python)
• Passlib (Password encryption & decryption module for python)
• Gevent (By default, trinity uses gevent as an wsgi. You can use any, though.)

What makes Trinity 3 shine

• The ability to automatically install required modules
• The ability to quickly render html templates
• The ability to automatically create all database tables
• The ability to run trinity on a custom port. (example

• Clean and easy mvc structuring.
• Easy to further develop upon.

Common Questions
Q: How does trinity go about templating?
A: Trinity uses flask's built in jinja2 templating system. Docs:

Q: Does trinity work across multiple platforms?
A: Yes, python itself is very cross platform, but i made sure to code the cms to work on linux and windows in specific.

Q: Have you experienced any bugs, crashes or memory leaks yet?
A: I've been using this very cms on

Report bugs if there's any, and i'll try to push a fix for it when i can.

Installation

1. Download Python 3.6.1 over at

2. Go into cmd, type "python" make sure it works otherwise you need to set it as a path variable (annoying)

3. Configure build/settings.py
4. Run python trinity_server.py, everything from there on is automated.
   
5. Reboot Trinity after setup is complete (bug)

Cheers!

Ah, you released your personal portfolio

I remember playing on the admin panel with it in the past

Yup yup, i must say this project ended up maturing pretty well.
Much more faster, modular and neater.

Throw back

Now

 

[Berk]

Oh the new version. Nice to see, wanna add features to it!

 

[Macemore]

Now make it run on linux!

 

[griimnak]

Now make it run on linux!

It does! (python 3.4+) just run it with python trinity_server.py

or are you just trolling

 

[TheRealMoonman]

Probably one of the most unique development projects ive seen on devbest probably, even better. it actually got released lmao.
Fantastic job.

Thanks man!
There's more to come, I eventually wanna get around using python's open and write functions to edit html from a dedicated admin panel, but that's when i actually get the motivation to get back into the grind again, though.

I'm looking forward to seeing it, its definitely a very useful language, have you tried Django?

I didn't see trinity_server.py, so not trolling, just ignorance.

Quick Update
Setup is now 100% automated, the user no longer needs to edit build/settings.py, instead trinity will take the user through a process of data gathering then writing that data into the configuration file via python's open() function, when build/settings.py is not found.

as always, the code's been updated over at

Working on Trinity Admin
Started doing some work on trinity's admin panel today, mainly because i stumbled across this really great admin theme

Login model completely rewritten, removed nesting code and implemented more object oriented approaches.

(login controller

I've also re-written most of my core engine to support flask-socketio

Updates aren't pushed yet, but will be pushed by the end of this week when it's all stable
 
Conclusion for the night
Off for the night, the general layout of the admin theme is now finished with some inspiration from @HighlySkilledHabbo's

Thanks! Yeah i've been trying to become more pro with python, my goal is to master it, learn all the correct practices, then move on to another language and grind it for awhile like i did with python.

That's the thing with programming languages though, you never can fully master it. That's what makes it great.

You're making great progress.

Nightly Update
I've completely rewritten the database connector into an object oriented class, and added the option to ping mysql every x seconds because i found that sometimes if i left the console server online for 2 days+ it'd say "mysql sever has gone away".
I'm not too worried about it though because you'll most likely put trinity into a virtual env if you're making your site live on a webhost, but you can still keep it open on a vps like a habbo emulator for example, if you want.

(validate_connection() and keep_connection_alive() are kept outside the handler because of how Trinity's core is designed)

import time
import pymysql
from build import settings
import threading


# KeepAlive: [True | False]
# Pings MySQL every x seconds
KeepAlive = dict(
    Enabled=True,
    Duration=60
)


class _Handler:
    # Create database instance
    def __init__(self):
        try:
            self.conn = pymysql.connect(
                settings.mysql['db_host'],
                settings.mysql['db_user'],
                settings.mysql['db_pass'],
                settings.mysql['db_name']
            )
        except Exception as error:
            self.throw_connection_failed_error(str(error))

    def throw_connection_failed_error(self, error):
        print(' [NOTICE] Database connection failed: {}').format(error)
        exit()


def validate_connection():
    if _Handler().conn.open is False:
        print(' [NOTICE] Database connection failed.')
    else:
        print(' * Database connected successfully!')


def keep_connection_alive():
    while True:
        time.sleep(KeepAlive['Duration'])
        try:
            _Handler().conn.ping()
            print(' * KeepAlive -> Pinged MySQL')
        except(Exception, pymysql.OperationalError):
            print(' [NOTICE] Database connection died, reconnecting..')
            _Handler()
_Handler()

if KeepAlive['Enabled'] is True:
    t = threading.Thread(target=keep_connection_alive)
    t.start()

instance = _Handler().conn.cursor()
_Handler().conn.autocommit(True)

I'm not gonna put it on github untill i've finished some other things, that's all for now.
 
Started more work on the admin panel today, currently working on the configuration section.
