I have two models,
Series, where each Event belongs to a Series. Most of the time, an Event's
start_time is the same as its Series'
Here's a stripped down version of the models.
#models.py class Series(models.Model): name = models.CharField(max_length=50) default_time = models.TimeField() class Event(models.Model): name = models.CharField(max_length=50) date = models.DateField() start_time = models.TimeField() series = models.ForeignKey(Series)
I use inlines in the admin application, so that I can edit all the Events for a Series at once.
If a series has already been created, I want to prepopulate the
start_time for each inline Event with the Series'
default_time. So far, I have created a model admin form for Event, and used the
initial option to prepopulate the time field with a fixed time.
#admin.py ... import datetime class OEventInlineAdminForm(forms.ModelForm): start_time = forms.TimeField(initial=datetime.time(18,30,00)) class Meta: model = OEvent class EventInline(admin.TabularInline): form = EventInlineAdminForm model = Event class SeriesAdmin(admin.ModelAdmin): inlines = [EventInline,]
I am not sure how to proceed from here. Is it possible to extend the code, so that the initial value for the
start_time field is the Series'
