Django Basics - kgolezardi/SAD-Project GitHub Wiki

First, we need a virtual environment! We used virtualenvwrapper to make one with the following commands:

$ pip install virtualenvwrapper
$ export WORKON_HOME=~/Envs
$ mkdir -p $WORKON_HOME
$ source /usr/local/bin/virtualenvwrapper.sh
$ mkvirtualenv bidilo -p python3

We should add Django to requirements, but for now:

$ pip install django

$ django-admin startproject mysite
$ python manage.py runserver
$ python manage.py startapp core

Why to use reverse_lazy instead of reverse?

It is useful for when you need to use a URL reversal before your project’s URLConf is loaded. Some common cases where this function is necessary are:

• providing a reversed URL as the url attribute of a generic class-based view.
• providing a reversed URL to a decorator (such as the login_url argument for the django.contrib.auth.decorators.permission_required() decorator).
• providing a reversed URL as a default value for a parameter in a function’s signature.
