Re: Django Python OSError No such file or directory but file exists

Turns out unoconv takes 2 seconds to perform the file conversion.

So after the file conversion, I had to set time.sleep(3) before upload a file to S3.

And after 1 week I got this working using variables.

Thanks

I don't know why but if I set the string ("cv.pdf"), it process just fine.

If I use a variable instead, it doesn't.

Here is the working code:

        # convert to PDF

        env = os.environ.copy()

        env['HOME'] = '/tmp'

        subprocess.Popen(["unoconv","-f", "pdf", "-o", "cv.pdf","%s" % (file_in)], env = env)

        # Define S3 path

        resume_path = 'resumes/%s/' % str(date.today())

        

        # key is the S3 file name

        key = '%s%s' % (resume_path, file_out)

        

        # delete local file

        subprocess.call("rm -f %s" % user_cv_file, shell=True)

        

        # update the new file format

        user_cv.resume = key

        user_cv.save()

        

        # S3 Connection

        conn = S3Connection(settings.AWS_ACCESS_KEY_ID, settings.AWS_SECRET_ACCESS_KEY)

        bucket_out = Bucket(conn, settings.AWS_STORAGE_BUCKET_NAME)

        k_out = Key(bucket=bucket_out, name=user_cv.resume)

        # Upload to S3

        k_out.set_contents_from_filename('cv.pdf')

        k_out.make_public()

        # deleta o arquivo localmente

        subprocess.call("rm -f cv.pdf", shell=True)

Well, yeah, you're using local path basically. And you should NEVER use .split('/')[-1] to determine file basename, take a look at os.path module instead.

But that's not the point. You should try to use absolute path, I believe it would do the trick.

the method is called in a def post() within a class view:

user_cv = CandidateCV.objects.get(user=request.user)

user_cv_file = str(user_cv.resume).split('/')[-1]

s3upload(user_cv_file)

The file is converted from doc to pdf in server project folder, where manage.py is.

So probably there is no absolute path.

How can I solve it?

Thanks

Hi,

Are you sure s3file contains absolute path? I can't see where s3upload is being called.

Also, you might wanna use os.remove instead of calling subprocess.

You also might wanna check out PEP-8 and Sphinx for your docstrings.

I'm converting doc and docx files to pdf in the server using unoconv with LibreOffice. And I need to upload to S3 the converted file. I can convert with success the files and I can see them in the server. But when I try to upload the pdf, I get the error. What am I missing? Thanks in advance This works just fine: import subprocess from boto.s3.connection import S3Connection, Bucket, Key def doc_to_pdf(user): ''' Convert doc or docx to PDF. parameter user: is a request.user Usage: doc_to_pdf(self.request.user): ''' user_cv = CandidateCV.objects.get(user=user) user_cv_file = str(user_cv.resume).split('/')[-1] # tem que ser PDF user_cv_filetype = user_cv_file.split('.')[-1] if not user_cv_filetype in settings.PDF_FILE_TYPE: # Se não for PDF file_in = user_cv.resume.url file_name = file_in.split('/')[-1] # download urllib.request.urlretrieve(file_in, file_name) file_out = user_cv_file.split('.')[0] + '.pdf' # converte para PDF env = os.environ.copy() env['HOME'] = '/tmp' subprocess.Popen(["unoconv","-f", "pdf", "%s" % (file_in)], env = env) # Define a path para salvar o documento na S3 resume_path = 'resumes/%s/' % str(date.today()) # key é o nome do arquivo na S3 key = '%s%s' % (resume_path, file_out) # deleta o arquivo localmente subprocess.call("rm -f %s" % user_cv_file, shell=True) # Salva o novo formato no banco user_cv.resume = key user_cv.save() This is the code in which I get the error in line: k_out.set_contents_from_filename(s3file) def s3upload(s3file): # Conecta na AWS S3 conn = S3Connection(settings.AWS_ACCESS_KEY_ID, settings.AWS_SECRET_ACCESS_KEY) bucket_out = Bucket(conn, settings.AWS_STORAGE_BUCKET_NAME) k_out = Key(bucket=bucket_out, name=s3file) # Define a path para salvar o documento na S3 resume_path = 'resumes/%s/' % str(date.today()) # key é o nome do arquivo na S3 key = '%s%s' % (resume_path, s3file) k_out.key = key # Salva na AWS S3 k_out.set_contents_from_filename(s3file) k_out.make_public() # deleta o arquivo localmente subprocess.call("rm -f %s" % s3file, shell=True)
