I'm working on an application that takes a Turtle Art (.ta) file, runs
it, creates a .png of the result, and displays it in a table. So far I
can create the .png and it's placed in the uploads folder with the
same name as the original .ta file but when i try to run
session.new_image = form.vars.file
session.new_image_title = form.vars.title
file_name_length = len(session.new_image)
os.system('python applications/turtle_art_images/modules/
PngGenerator.py applications/turtle_art_images/
uploads/'+session.new_image)
db(db.comment.title==session.new_image_title).update(newimage=os.system('applications/
turtle_art_images/uploads/'+session.new_image[0:(file_name_length-2)]
+'png'))
return dict()
where form.vars.file is the uploaded .ta file
I get the errors:
ERROR:Rocket.Errors.ThreadPool:Traceback (most recent call last):

and I'm totally lost as to why. Any ideas?
