Hi Marta,

This error was a bit tricky to figure out, but it can be traced back to your order_by Meta attribute in your Post model.

order_by must be a tuple, and it looks like you simply forgot to add the comma to make it a tuple.

class Post(Model):
  timestamp = DateTimeField(default=datetime.datetime.now)
  user = ForeignKeyField(
    rel_model=User,
    related_name='posts'
  )
  content = TextField()

  class Meta:
    database = DATABASE
    order_by = ('-timestamp',) # Add comma
