Quick Start

  1. Initialize and activate a virtualenv:
    • for windows
      virtualenv env
      \path\to\env\Scripts\activate
    • for linux
     sudo apt install python3-venv
     python3 -m venv env
     source env/bin/activate
  2. Install the dependencies:
     pip install -r requirements.txt # for windows
     pip3 install -r requirements.txt # for linux
  3. For database configuration in config.py
    POSTGRES = {
     'user': 'postgres',
     'pw': 'password',
     'db': 'my_database',
     'host': 'localhost',
     'port': '5432',
     }
    SQLALCHEMY_DATABASE_URI = 'postgresql://%(user)s:\%(pw)s@%(host)s:%(port)s/%(db)s' % POSTGRES 
  4. Run command for database migration:
     flask db init
     flask db migrate -m "Initial migration."
     flask db upgrade
  5. Run the development server:
    • for windows
     set FLASK_APP=run.py
     set FLASK_ENV=development
     flask run
    • for linux
     export FLASK_APP=run.py
     export FLASK_ENV=development
     flask run
