There are a couple of things to fix in the models.py file before we can test our new functionality.  We'll go through these steps to address them:

    def __init__(self, filename, filepath=None):
        if filepath:
            if not os.path.exists(filepath):
                os.mkdir(filepath)
            self.filename = os.path.join(filepath, filename)
        else:
            self.filename = filename

If filepath is specified, we need to first make sure the directory exists. Since the mkdtmp() method called in the Application class does not actually create a temporary directory, we'll create it here. Once that's done, we'll join the filepath and filename values and store it in the CSVModel object's filename property. ...
