[Answer]-How to save a local file in a FileField in django

It looks like your issue is not with the FileField, but occurs when saving the VoiceMessage instance instead.

In the traceback, the failure occurs at the end of FieldFile.save():

  File "/home/israelord/.virtualenvs/ringtu-env/local/lib/python2.7/site-packages/django/db/models/fields/files.py", line 95, in save
    self.instance.save()

Which means that everything went fine there, and only when this method in turns call save() on the vm object does the problem arise:

# FileField.save() calls instance.save() just before returning
# Here, self.instance is the vm object
def save(self, name, content, save=True): 
    name = self.field.generate_filename(self.instance, name) 
    self.name = self.storage.save(name, content) 
    setattr(self.instance, self.field.name, self.name) 

    # Update the filesize cache 
    self._size = content.size 
    self._committed = True 

    # Save the object because it has changed, unless save is False 
    if save: 
        self.instance.save()

My best guess is the problem is on vm.date or another DateTimeField field, as the exception is raised in DateTimeField.to_python function. Can you check the type of msg['when']? You can also confirm this by skipping the instance save step:

vm.message.save(filename, File(msg['file']), False) # Added False
msg['file'].close()
vm.save() # Error should now be raised here
