Question

I am creating a powerlifting database, or trying too. I have a users Squat, deadlift and Bench Press amounts. Lets say i want to add just there deadlift and benchpress amounts, for example, but not store it, in mysql shell i do this:

mysql> SELECT sq, dl, bp, sq+dl AS sq_+_dlweight FROM mysite_weightsprofile

Ok, i get that.

In views i can do this as so:

conn = mdb.connect('localhost', 'bobby', '#########', 'website');
cursor = conn.cursor()
cursor.execute("SELECT sq, dl, bp, sq+dl AS sq_+_dlweight FROM mysite_weightsprofile")
rows = cursor.fetchall()

However, this method seems quite convaluted, difficult to appropriate into templates and not very adjustable. Is there a way i can do the above using the short code

query_results = UserProfile.objects.all("?")

without having to create a cursor object.

Just add a method to your model. For instance:

class UserProfile(Model):
    squats = IntegerField(null=True, blank=True)
    deadlift = IntegerField(null=True, blank=True)

    def squats_and_deadlifts(self):
        return self.squats + self.deadlift

Then in your template:

{% for user_profile in query_results %}
Deadlifts + squats: {{ user_profile.squats_and_deadlifts }}
{% endfor %}
