Re: adding field to query set

What's your motive? Are you worried about performance?

If performance is not an issue, you can just do this:

for project in Project.objects.all():
print project.user.first_name + ' ' + project.user.last_namea

This might speed things up:

projects = Project.objects.all().select_related('user')
for project in projects:
print project.user.first_name + ' ' + project.user.last_namea

If that's not fast enough, you may want to do something using .extra()
or .raw(). I'm not sure how to do this effeciently with .extra().
