P.S. I left two bugs in there, for now I'll leave them in as an
exercise for the reader.
Three bugs ... and 2 questions:
1. You obviously forgot the sugar!
2. With that proportion of Earl Gray the tea would have been far too strong.
3. There might be 5% discrepancy in the total!
Now for the questions ...
class CalculatedPercentageField(models.PositiveSmallIntegerField):
pct_model = None
pct_field_name = None
def __init__(self, pct_model: models.Model, pct_field_name='percentage',
*args, **kwargs):
self.pct_model = pct_model
self.pct_field_name = pct_field_name
super().__init__(*args, **kwargs)
...
1. What does "pct_model: models.Model," do? I haven't seen that colon
before.
2. Will it work when used via the Admin and everything gets saved at
once in a single transaction?
Thanks very much for taking all that effort
Cheers
Mike
