Flask_Base:

It's a MVT structure to start developing web applications based on Flask. The structure is improved to work with PostgreSQL, but you can also work with any other RDBMS. There's also a simple Blackjack game made with jQuery's ajax functionality to provide an example of how to communicate with the server's routes, just for fun.

Git Clone and Deploy:

To start working with it you must clone this repository and provide a optimal virtualenvironment in order to deploy Flask_Base. It's important to install virtualenvwrapper on your system, it's a great tool to manage virtualenv.

Your system must have Postgresql installed, and the following packages will be required:

postgresql-11 libpq-dev python3-dev

Remember:

You must configure a user and a database for your application on PostgreSQL!

---

After you've installed those system dependencies, you can proceed cloning Flask_Base:

  

# git clone http://github.com/MarcelFox/flask_base

  

# cd flask_base/

  

# mkvirtualenv --python="/usr/bin/python3" -r requirements.txt venv_name

  

This flask base structure uses environment variables which works very well with virtualenvwrapper. At this point we have to set up only two variables:

SECRET_KEY

DATABASE_URL

Just add the following lines into the postactivate file on your virtualenv:

$HOME/.virtualenvs/venv_name/bin/postactivate:

  

export FLASK_APP='$HOME/flask_base/run.py'

  

export SECRET_KEY='Shrubbery'

  

export DATABASE_URL='postgresql://USER:PASS@localhost/DATABASE'

  

You also need to unset these variables when you deactivate from your virtualenv:

$HOME/.virtualenvs/venv_name/bin/postdeactivate:

  

unset FLASK_APP

  

unset SECRET_KEY

  

unset DATABASE_URL

  

Run!

(venv)$ uwsgi --ini="uwsgi.ini"

Now your application will be accessible on:

http://localhost:8080/
