Re: PDF response using wkhtmltopdf.

[Bill Freeman]

The return value of Popen isn't the output of the program, but instead
is the class instance.  I believe that you could provide a cStringIO
instance as the 'stdout' keyword argument, and it would capture
the program's output.  You could them use its getvalue() method's
return value as your HttpResponse method's first arguemnt.

But you should also check the command response status, and return
your choice of error message if it fails.  I suspect that there's a Popen
method to wait for the process to complete and check it's status.

It's all in the Popen documentation, I'm sure, probably with examples.

PDF response using wkhtmltopdf.

[juanefren]

I am using wkhtmltopdf to create PDF files, how ever I don't know how
to return them properly, docs says using a single dash instead of
output file name will write that to stdout. But I don't realize how to
return that content.

I have been trying using subprocess.Popen this way:

r = HttpResponse(Popen(command_args), mimetype='application/pdf')
r['Content-Disposition'] = 'filename=my_file_name.pdf'
return r

But I am not getting the result.

The only way I have managed to work is writting to file system in
media folder, and then redirect to the url based file, but this way
doesn't look good.

Thanks in advance.
