Using Python s os path how do I go up one directory

Question

I recently upgrade Django from v1 3 1 to v1 4   In my old settings py I have   TEMPLATE DIRS         os path join os path dirname    file       templates   replace                   Put strings here  like   home html django templates  or  C  www django templates         Always use forward slashes  even on Windows        Don t forget to use absolute paths  not relative paths      This will point to  Users hobbes3 Sites mysite templates  but because Django v1 4 moved the project folder to the same level as the app folders  my settings py file is now in  Users hobbes3 Sites mysite mysite  instead of  Users hobbes3 Sites mysite    So actually my question is now twofold    How do I use os path to look at a directory one level above from   file    In other words  I want  Users hobbes3 Sites mysite mysite settings py to find  Users hobbes3 Sites mysite templates using relative paths  Should I be keeping the template folder  which has cross-app templates  like admin  registration  etc   at the project  User hobbes3 Sites mysite level or at  User hobbes3 Sites mysite mysite

I think the easiest thing to do is just to reuse dirname() So you can call

os.path.dirname(os.path.dirname( __file__ ))

if you file is at /Users/hobbes3/Sites/mysite/templates/method.py

This will return "/Users/hobbes3/Sites/mysite"

To get the folder of a file just use   os path dirname path     To get a folder up just use os path dirname again  os path dirname os path dirname path     You might want to check if   file   is a symlink    if os path islink   file     path   os readlink    file

from os path import dirname  realpath  join join dirname realpath dirname   file        templates     Update   If you happen to  copy  settings py through symlinking   forivall s answer is better    user      project1            mysite              settings py         templates              wrong html      project2          mysite              settings py - gt   user project1 settings py         templates              right html   The method above will  see  wrong html while  forivall s method will see right html  In the absense of symlinks the two answers are identical

If you are using Python 3 4 or newer  a convenient way to move up multiple directories is pathlib   from pathlib import Path  full path    path to directory  str Path full path  parents 0       path to  str Path full path  parents 1       path  str Path full path  parents 2

os path abspath os path join os path dirname    file             templates      As far as where the templates folder should go  I don t know since Django 1 4 just came out and I haven t looked at it yet  You should probably ask another question on SE to solve that issue   You can also use normpath to clean up the path  rather than abspath  However  in this situation  Django expects an absolute path rather than a relative path   For cross platform compatability  use os pardir instead of
