Any idea, where I should look into it. Let me know if you need any specific file.

This simply means that self.status is somehow returning a None value. So insert a check and try like this:
if self.status != None:
self.status.split(' ',1)[0]

Note that I'm still able to play the audio file my template view, but I can't seek to a specific duration of this file. Any hints as to why this is happening ?
Here's my code for models.py :
class Song(models.Model):
song_name = models.CharField(max_length=100)
album_name = models.ForeignKey(Album, on_delete=models.CASCADE)
song_file = models.FileField(upload_to='songs/', null=True,
validators=[validate_song_extension])
def get_absolute_url(self):
return reverse('music:song-detail', kwargs={'pk': self.pk})
def __str__(self):
return self.song_name
I am using a simple CreateView to accept new entries for this Song model with no form_valid() method, is that the possible cause I'm getting this error ?
