I have a simple bottle.py app that let’s me upload files. Now since those files can be quite big i wanted to have a progress bar. I found jqUploader which looked to be like just what i wanted but now i have trouble getting it to work.
My upload worked perfectly when i had my own form but now i don’t know how to properly acces the data anymore.

py:

@route('/upload')
def upload():
  return static_file('upload_form.html', root='html')

@post('/load_from_file')
def load_from_file():
  print("Uploading...")
  name = request.forms.name
  data = request.files.myFile3
  print(data)
  filename = data.filename
  with open(os.path.join("C:\\", filename), "wb") as file_object:
      bytes = 0
      while True:
          datachunk = data.file.read(1024)
          if not datachunk:
              break            
          file_object.write(datachunk)
          bytes  += len(datachunk)
  return "Hello %s! You uploaded <b>%s</b>." % (name, filename)

    Here’s the working code (didn’t change anything in the html or js):

    @route('/upload')
def upload():
    #Upload-Form
    return static_file('upload_form.html', root='html')

@post('/load_from_file')
def load_from_file():
    #Actual Uploading
    if request.POST.Upload == 'Submit Query':
        try:
            data = request.POST.Filedata.file
            filename = request.POST.Filename
            filepath = os.path.join(settings.FOLDERS["TEMP_WORKING"], filename)
            with open(filepath, "wb") as file_object:
                while True:
                    datachunk = data.file.read(1024)
                    if not datachunk:
                        break            
                    file_object.write(datachunk)
            process_files_upload(filepath)            
        except:
            print(traceback.format_exc())
        #Check if only uploaded or already finished
        return "Upload Finished"
    else:
        redirect('/upload')
