What am I doing wrong?
class MyModel(models.Model): name = models.CharField(max_length=100, verbose_name=_("Name"), blank=False, null=False) rating = models.DecimalField(max_digits=2, decimal_places=2, default=0)
I do something like that:
average = count/len(votes) mymodel.rating = average mymodel.save()
count is the sum of all ratings of given
MyModel and votes is an array of those ratings, their division gives an average rating for MyModel (sorry if I described it incorrectly due to my poor English).
If i change previous to:
mymodel.name = 'anything' mymodel.save()
Then ‘anything’ ends up in the database, but rating does not.
Why? am I using wrong field type?
max_digits is a number of digits before and after the decimal point. With your settings it allows you to store numbers between 0.00 and 0.99. Is it right? I can not figure out the range of values for average variable.
