Hey, I am trying to do something very simple....
I have a downloads app in my django project. It has some fields like
file name, file path, file type and file size. What I wish is to take
the file path and get the file size via maybe getsize function in os,
but how can I write equivalent code for the same. I tried doing
something like this but it gave some errors( I am new at python as
well, so remind me of bad programming practices i had followed :P )
import .... #appropriate import satatements
FILETYPE_CHOICE=(
('Audio/Video','Audio/Video'),
('Text/Word','Text/Word'),
('source','Source Archives'),
('Binary','All other files go here!'),
)
class Files(models.Model):
"""Uploads area, all files to be ready for user use are put here"""
filepath = models.FilePathField(_('Choose File'),path="/home/sanket/
Music")
filedescription = models.CharField(_('File
Description'),max_length=100)
filetype = models.CharField(_('File
Type'),max_length=1,choices=FILETYPE_CHOICE)
fileuploadtime = models.DateTimeField(_('File Upload Time'))
def __unicode__(self):
return self.filepath
class Admin:
list_display =
('filepath','filesize','fileuploaddate','fileuploadtime')
list_filter = ('fileuploaddate')
def getSizeFromFilePath(filepath):
return os.path.getsize(filepath)
filesize = getSizeFromFilePath(filepath)
The problem is that the server grumbles about the path not being
available.... which seems logical, we havent put any till now :P.....
but then how do u accomplish such a task of modeling some of the
columns using the other column's information??
I got the above idea from the djangobook chapter on models. It didnt
talk much more detail... so I am rather helpless. Any help is
appreciated....
