PyBelfast - Comparison between Django and Flask

Rebecca Martin, PyBelfast @laches1sm 

So wtf am I talking/slabbering about now?

• Do you really want to know?
  • Yes?
    • Oh no
    • Comparing Flask with Django
    • At least there might be parrots?

What even is Django and Flask?

• Both are web frameworks compiled in Python, used for building web applications, APIs, etc....
• Flask is a microframework, Django is simply a framework

Flask / Django

• Differing aims - Flask aims to 'keep the core simple but extensible' 
• Django - more about encouraging rapid development

Flask / Django

• Flask is based on WSGI - so needs a central callable object that is the implementation of the application 
• Gives several advantages:
  1. Subclassing
  2. Reflection of information 
  3. 'Explicit is better than implicit' 

Flask / Django

• Django is more based on the MVC principle:
• ORM --> Data model --> View --> Controller
• Django does most of the work for you
• Less customisable than Flask 

Flask / Django - Routing

• Flask - Werkzeug 
• Django - URL dispatcher/URL Conf

Flask / Django - Templates

• Flask - Only one template - Jinga2 
• Django - Can use many - default is Django Template language

Flask / Django - Best situation

• Flask is great if you want to customise anything and everything
• Django - has most everything bundled with it - a great Python web framework for beginners

Flask / Django - General Differences

• Flask is built on customisability - can be extended
• Django is built to take care of most web development concerns

Flask / Django - Any questions
