Models:
class Technology(models.Model):
name = models.CharField(max_length=100, unique=True)
slug = models.SlugField(max_length=100, unique=True)
class Site(models.Model):
name = models.CharField(max_length=100, unique=True)
slug = models.SlugField(max_length=100, unique=True)
technology = models.ManyToManyField(Technology, blank=True, null=True)
Views:
def portfolio(request, page=1):
sites_list =
Site.objects.select_related('technology').only('technology__name', 'name',
'slug',)
return render_to_response('portfolio.html', {'sites':sites_list,},
context_instance=RequestContext(request))
Template:
{% for site in sites %}
<div>
{{ site.name }},
{% for tech in site.technology.all %}
{{ tech.name }}
{% endfor %}
</div>
{% endfor %}
But in that example each site makes 1 additional query to get technology
list. Is there any way to make it in 1 query somehow?
