Prerequisites#

A few tools need to be installed in the system to use the starter efficiently:

  • Python

  • A modern code editor like VsCode, or Sublime

  • (optional) GIT - for pulling the source code and work under a version control system

  • (optional) Docker for isolated execution

  • (optional) DB Servers: - MySql - PostgreSQL

Download Source Code#

The product can be downloaded from the official product page or directly from GitHub (public repository)

git clone https://github.com/app-generator/flask-datta-able.git
cd flask-datta-able

Once the source code is unzipped, the next step is to start it and use provided features.

Start in Docker#

The fastest way to start the product is to execute the Docker set up:

docker-compose up --build

If Docker is properly installed in the system, you can visit the browser at http://localhost:5085. Product should be up and running.

Codebase#

The project is coded using a simple and intuitive structure presented below:

  • Core: holds the project settings

  • Home: the application that integrates the Datta Able Design

  • Api: the generated API

Manual Build#

It’s best to use a Python Virtual Environment for installing the project dependencies. You can use the following code to create the virtual environment

virtualenv env

To activate the environment execute env\Scripts\activate.bat for Windows or source env/bin/activate on Linux-based operating systems.

Having the VENV active, we can proceed and install the project dependencies:

pip install -r requirements.txt

Environment#

The starter loads the environment variables from .env file. Here are the critical ones:

  • DEBUG: set by default to False (development mode)

  • SECRET_KEY: a random value used by Django to secure sensitive information like passwords and cookie information

  • Database Credentials: DB_ENGINE, DB_USERNAME, DB_PASS, DB_HOST, DB_PORT, DB_NAME
    • if detected, the database is switched automatically from the default SQLite to the specified DBMS

Setting up the Database#

By default, the application uses SQLite for persistence. In order to use MySql / PostgreSQL, you’ll need to install the Python driver(s):

pip install mysqlclient # for MySql
# OR
pip install psycopg2    # for PostgreSQL

To connect the application with the database, you’ll need to fill in the credentials int the .env file and run the migrations.

.env#
DB_ENGINE=mysql
# OR
DB_ENGINE=postgresql

# DB credentials below
DB_HOST=localhost
DB_NAME=<DB_NAME_HERE>
DB_USERNAME=<DB_USER_HERE>
DB_PASS=<DB_PASS_HERE>
DB_PORT=3306

Set up the environment

export FLASK_APP=run.py

Use the following commands to set up the database:

# Init migration folder
flask db init # to be executed only once

flask db migrate # Generate migration SQL
flask db upgrade # Apply changes

Running the project#

The following command starts the project using Flask development server:

flask run              # Starts on default PORT 5000
flask run --port 8999  # Starts on PORT 8999 (custom port)

By default Flask starts on port 5000 but this can be easily changed by adding the PORT number as argument. At this point, the app runs at http://127.0.0.1:5000/

Create Users#

By default, the app redirects guest users to authenticate. In order to access the private pages, follow this set up:

  • Start the app

  • Access the registration page and create a new user: - http://127.0.0.1:5000/register/

  • Access the sign in page and authenticate - http://127.0.0.1:5000/login/
