I'm new to both python and django as well, but how about writing
a presentation method and mention that method in the list_display
of the admin interface, something like...
class Timecard(models.Model):
employee...
...
notes...
def get_week_result(self):
# make a result string like '0.0 4.5 8.0 8.0 ...etc.
# The 'start' field contains the weekday.
# or maybe one method for each day of the week.
return result
class TimecardAdmin(admin.ModelAdmin):
...
list_display = ('employee', ..., 'get_week_result')
...
However, the model you defined is slightly askew from your
presentation, if you want to look at a week at a time,
maybe you'd be better of defining the model/record as
being a week. Simply make things easier on yourself.
