PracticalDjangoProjects 筆記一

1. A Django project is a wrapper of sorts, which contains settings for one or more Django-powered applications and a list of which applications it uses.

2.  ADMONITION: PERMISSION ERRORS
If you’re using Linuxor Mac OS X,you may see an error message saying “permission denied.”If this happens,you need to tell your operating system that the django-admin.py script is safe to run as a program.You can do this by navigating to the directory that django-admin.py is in and typing the command chmod +x django-admin.py.

3. ADMONITION: CHANGING THE ADDRESS AND PORT
If something else is already using port 8000 on your computer,if you’re not allowed to run programs that bind to that port,or if you want to view pages served by Django’s development server from another computer,you’ll need to manually specify the address and port to use when you launch the development server.The syntax for this is python manage.py runserver ip_address:port_number.So,for example,to listen on all of your computer’s available IP addresses (so that other computers can view pages from the development server) and bind to port 9000 instead of 8000,you could type python manage.py runserver 0.0.0.0:9000.
