Hello,
I am trying to perform a complex math calculation from a django query set.
How can I pass the results to the template for display? Annotations won't
work since the math is not a simple sum, diff or average.
MODEL
class TncData(models.Model):
callsign = models.TextField(max_length=2
7 matches
