OSError: [Errno 2] No such file or directory

I have the below code to make a directory and then have a file upload to the directory. The same code works fine in a similar view in the same app, so I'm not sure what to think. Any ideas?

The code from the views is below:

    if form.validate_on_submit():
        # for document in form:
        dir_name = str(school.id) + '_' + school.englishname.replace(' ','_').lower() + '/'
        try:
            os.stat('static/schools/' + dir_name)
        except:
            os.mkdir('static/schools/' + dir_name)
        pic_files = request.files.getlist("picfiles[]")
        doc_files = request.files.getlist("docfiles[]")
        if pic_files[0].filename:
            for item in pic_files:
                if allowed_file(item.filename.lower()):

I launched a console from the base directory and used os.mkdir('static/schools/acme_school') to successfully create a new directoy. What gives?

Try os.mkdir('/static/schools/acme_school')

If you look at the error,

No such file or directory:
> 'static/schools/acme_school/'

you will see that it means that it cannot find static/schools, or even static, and that's why it cannot mkdir acme_school there.

So you should use an absolute file path instead of a relative path because you never know where the current working directory is. That is what graingerkid is saying with the extra '/' in front. However, the correct file path is probably something like /home/leapfrog/<your-webapp-name>/static/schools/acme_school/

Also as a side note, I just want to point out that you want to serve your static files staticly, otherwise your website will be super slow later on.

@graingerkid @conrad Your responses are much appreciated and thanks for the info on serving the files staticly. I changed the path to an absolute path as conrad suggested and it now works fine now.
