Hi am very new to Django/Python and I need some help with a model
method
I have two tables Linked by a foreign key and their forms are embedded
in the admin interface.
One table is called Quote and one table is called Task. The task table
has a field called time_taken
In the Quote list I want to display the total amount of time to under
go all the tasks in each quote.
This is what I'm doing and its just displaying (None) in the list
class QuoteAdmin(admin.ModelAdmin):
fieldset = [
(None, {'fields': ['q_number']})
]
inlines = [TaskInline]
list_display = ('q_number', 'total_time','created_date')
def total_time(self,queryset):
task_objs = self.Task.objects.all()
total_time = 'No time taken'
for record in task_objs:
total_time = total_time + record.time_taken
return total_time
I'm trying to get all the tasks for each quote by doing
self.Task.objects.all() and then looping through them and adding the
time_taken to the var total_time.
I guess this syntax is just plain wrong or the method is not being
called as its not showing any errors
I have a javascript/PHP background and I would like to learn more
Python
- Please be kind :)
