I am using the os module to have relative paths in my Django projects settings.py
file. The variable SITE_ROOT is set to the current working directory of the settings.py
file and then used to reference all of the static/media
directories also located in that same directory.
Heres my issue:
print os.getcwd() print os.path.abspath(os.path.dirname(__file__))
In settings.py, the above statements both have identical outputs. but my template will only load if I use SITE_ROOT = os.path.abspath(os.path.dirname(__file__))
Django looks for the templates here:
TEMPLATE_DIRS = ( os.path.join(SITE_ROOT, 'templates'), )
SITE_ROOT set to os.getcwd()
seems to make Django look for the templates folder in the directory ABOVE the settings.py
file
I can just as easily not use os.getcwd()
and my site runs fine, but I am curious what may be going on here :)
Anyone know?
path. abspath() returns a normalized absolutized version of the pathname path which may sound fancy but it simply means that this method returns the pathname to the path passed as a parameter to this function.
path. dirname() method in Python is used to get the directory name from the specified path.
os. getcwd() returns the absolute path of the current working directory where Python is running as a string str .
os. getcwd() method tells us the location of current working directory (CWD). Parameter: No parameter is required. Return Value: This method returns a string which represents the current working directory.
As mouad said, os.getcwd()
won't give you exactly what you're expecting.
os.getcwd()
does a bit more than returning the current working directory. It defaults to $PWD in your env. It's not where the script is located but where you were when you executed the script.
Being in /home/user
and doing python manage.py
, os.getcwd()
will return /home/user
Being in /home/
and doing python user/manage.py
, os.getcwd()
will return /home
But it's still won't be always true since it's possible to use os.chdir()
. It is in other word like doing cd
. It will also change the return value of os.getcwd()
.
On the other hand. __file__
is the path of the module file. So you have to use this to be certain to have a path relative to your module instead of the current working directory that may change.
As ShawnFumo said, __file__
might not be always absolute. To get a better idea on how it works, you can check that answer: Python __file__
attribute. Also, as of Python3.4 __file__
should always be an absolute path.
The command os.path.abspath(os.path.dirname(__file__))
returns the directory in which the code file is stored, but os.getcwd()
gives you your current working directory which is by default where the code was executed, the latter can be changed using the os.chdir()
command.
