Basics

Install

Structure

• Project == site: app == service. project many to many app
• apps can live anywhere in the python path

Routing

• Each app can define routes in a URLconf file
• The routing file is included in the main site routing URLconf
• include chops off matched url part and sends to included for further processing
• Patterns don’t search GET and POST parameters, or the domain name
• Route has url, route name, view (HttpRequest handler) + kwargs. Like in Symfony

Difference django / symfony

• django lighter and more options for views

Orm

• saving directly on the entitiy
• not great: magical methods in django (e.g. backward one to many, always use default args)
• app should be added to the installed apps

• relations
  • one to many : ForeignKey on the owning side
  • many to many : ManyToManyField
  • one to one : OneToOneField
