Hi all, I'm just trying to learn Django. I have an existing site that I wrote in PHP, and I'l considering converting it to Django,
I have a legacy database that I don't want to make any changes to. I have the basics working in Django, but am having a problem with a ManyToManyField. Here are the 2 tables (simplified) class Played(models.Model): played_id = models.IntegerField(primary_key=True) track_id = models.IntegerField() date_played = models.DateTimeField() played_by = models.CharField(max_length=255L) played_by_me = models.IntegerField() class Meta: db_table = 'played' class Song(models.Model): id = models.IntegerField(primary_key=True) title = models.CharField(max_length=255L, blank=True) #These are what I've tried for ManyToMany with the error played = models.ManyToManyField(Played, db_column='id') # DatabaseError: (1146, "Table 'ampache.song_played' doesn't exist") played = models.ManyToManyField(Played, db_column='track_id') # DatabaseError: (1146, "Table 'ampache.song_played' doesn't exist") played = models.ManyToManyField(Played, db_table = 'played', db_column='id') # DatabaseError: (1054, "Unknown column 'T2.song_id' in 'where clause'") played = models.ManyToManyField(Played, db_table = 'played', db_column='track_id') # DatabaseError: (1054, "Unknown column 'T2.song_id' in 'where clause'") played = models.ManyToManyField(Played, through = 'played', db_column='id') # AttributeError: 'ManyToManyField' object has no attribute '_m2m_reverse_name_cache' class Meta: db_table = 'song' The code to produce the errors: > from djmusic.models import Song, Played > s = Song.objects.get(id=1229) > print s.title # Prints the title correctly > print s.played.all() # Generates one of the above errors > I know it's gotta be something simple I'm missing here. If I can get this figured out, there's a good chance that I'll convert my old PHP based site to Django.
