Django queryset not ordering correctly on production

StackOverflow https://stackoverflow.com/questions/14575910

Pergunta

I have a model:

models.py

class Person(models.Model):
    name = models.CharField(...)

    def __unicode__(self):
        return u'%s' % self.name

class Entity(models.Model):
    client = models.ForeignKey(Person)

In my view I just want to obtain all the Entities and order them by the name of the client:

views.py

def all_entities(request):
    entities = Entity.objects.all().order_by('client')
    return render(request, 'template.html', {'entities': entities})

And so my template just prints all the entities.

template.html

<html>
{% for entity on entities %}
 {{ entity.client }}}
{% endfor %}
</html>

Happens is that in my development PC all works pretty good, I get a list of ordered client names, what I can't understand is that on my production server on webfaction.com the result is not ordered alphabetically as in my local environment.

I testes it on the shell too, results are the same, somehow order_by('client') is returning an alphabetically sorted list on my PC but not alphabetically ordered on production.

Notes: Both environments have Postgres and use the same backend.

Thanks

Solução

Well, I'm not going to try to figure out why it appears to work for you, but I can't help but notice that the ORM wouldn't know which field to order by given a direct order to order by client.

It's probably just sorting by PK.

entities = Entity.objects.all().order_by('client__name') 
#                                               ^^^^^^ specify sort field
