For some reason order_by() is not working for me on a queryset. I've tried everything I can think of, but my Django/MySQL installation doesn't seem to be doing anything with order_by() method. The list appears to just remain in a fairly unordered state, or is ordered on some basis I cannot see.
My Django installation is 1.8.
An example of one of my models is as follows:
class PositiveTinyIntegerField(models.PositiveSmallIntegerField):
def db_type(self, connection):
if connection.settings_dict['ENGINE'] == 'django.db.backends.mysql':
return "tinyint unsigned"
else:
return super(PositiveTinyIntegerField, self).db_type(connection)
class School(models.Model):
school_type = models.CharField(max_length=40)
order = PositiveTinyIntegerField(default=1)
# Make the identity of db rows clear in admin
def __str__(self):
return self.school_type
And here is the the relevant line from my view:
schools = School.objects.order_by('order')
At first I thought the problem was related to having used the non-standard PositiveTinyIntegerField() defined by a class I found on a website somewhere which allows me to use the MySQL Tiny Integer field. However, when I ordered by 'id', or 'school_type' the list still remained in an ordered that appeared fairly random to my eye.
I could put in my own loop which orders the queryset after it has been retrieved, but I'd really rather solve this issue so I can use the standard Django way of doing it.
I hope someone can see where the issue may be coming from.
