Django ORM equivalent
Question
I have the following code in a view to get some of the information on the account to display. I tried for hours to get this to work via ORM but couldn't make it work. I ended up doing it in raw SQL but what I want isn't very complex. I'm certain it's possible to do with ORM.
In the end, I just want to populate the dictionary accountDetails from a couple of tables.
cursor.execute("SELECT a.hostname, a.distro, b.location FROM xenpanel_subscription a, xenpanel_hardwarenode b WHERE a.node_id = b.id AND customer_id = %s", [request.user.id])
accountDetails = {
'username': request.user.username,
'hostname': [],
'distro': [],
'location': [],
}
for row in cursor.fetchall():
accountDetails['hostname'].append(row[0])
accountDetails['distro'].append(row[1])
accountDetails['location'].append(row[2])
return render_to_response('account.html', accountDetails, context_instance=RequestContext(request))
Solution
It would be easier if you post models. But from SQL I'm assuming the models are like this:
class XenPanelSubscription(models.Model):
hostname = models.CharField()
distro = models.CharField()
node = models.ForeignKey(XenPanelHardwareNode)
customer_id = models.IntegerField()
class Meta:
db_table = u'xenpanel_subscription'
class XenPanelHardwareNode(models.Model):
location = models.CharField()
class Meta:
db_table = u'xenpanel_hardwarenode'
Based on these models:
accountDetails = XenPanelSubscription.objects.filter(customer_id = request.user.id)
for accountDetail in accountDetails:
print accountDetail.hostname, accountDetail.distro, accountDetail.node.location
