Question

I’m uploading a zipped folder that contains a folder of text files, but it’s not detecting that the folder that is zipped up is a directory. I think it might have something to do with requiring an absolute path in the os.path.isdir call, but can’t seem to figure out how to implement that.

            zipped = zipfile.ZipFile(request.FILES['content'])
            for libitem in zipped.namelist():
                if libitem.startswith('__MACOSX/'):
                    continue
                # If it's a directory, open it
                if os.path.isdir(libitem):
                    print "You have hit a directory in the zip folder -- we must open it before continuing"
                    for item in os.listdir(libitem):

The file you’ve uploaded is a single zip file which is simply a container for other files and directories. All of the Python os.path functions operate on files on your local file system which means you must first extract the contents of your zip before you can use os.path or os.listdir.

Unfortunately it’s not possible to determine from the ZipFile object whether an entry is for a file or directory.

A rewrite or your code which does an extract first may look something like this:

import tempfile

# Create a temporary directory into which we can extract zip contents.
tmpdir = tempfile.mkdtemp()
try:
    zipped = zipfile.ZipFile(request.FILES['content'])
    zipped.extractall(tmpdir)

    # Walk through the extracted directory structure doing what you
    # want with each file.
    for (dirpath, dirnames, filenames) in os.walk(tmpdir):
        # Look into subdirectories?
        for dirname in dirnames:
            full_dir_path = os.path.join(dirpath, dirname)
            # Do stuff in this directory
        for filename in filenames:
            full_file_path = os.path.join(dirpath, filename)
            # Do stuff with this file.
finally:
    # ... Clean up temporary diretory recursively here.
