Add multiple records at once in django admin panel - django

Question

I have following setup.
from django.db import models
from django.contrib.auth.models import User
class Event(models.Model):
name = models.CharField(max_length=64)
date = models.DateField()
ATTENDANCE_CHOICES = (
('A','Attending'),
('N','Absent'),
('L','Taken ill'),
)
class Attendance(models.Model):
student = models.ForeignKey(User)
event = models.ForeignKey(Event)
status = models.CharField(max_length=1, choices=ATTENDANCE_CHOICES)
In a nutshell: Students(User) attend or doesn't attend classes(Event), this is registered by Attendance.
Problem is adding those attendance records one at a time.
What I am looking for is a way to provide form for each class(each Event object) with list of all students and attendance status radio buttons or drop downs next to them.
Something like this:

I have looked at many discussions about multiple/bulk record insertion via django admin and am beginning to wonder is this even possible with django admin or do I have to create such form from scratch? Either way, what would be the best (most django-ish) approach?

Answer 1

"Is this even possible?" It's possible right out of the box.
Look into the django Admin app, Inlines, ModelForms, and the RadioSelect widget.
class MyForm(forms.ModelForm):
class Meta:
model = Attendance
def __init__(self, *args, **kwargs):
super(MyForm, self).__init__(*args, **kwargs
self.fields['status'].widget = forms.RadioSelect(choices=self.fields['status'].choices)
class AttendanceInline(admin.TabularInline):
model = Attendance
form = MyForm
class EventAdmin(admin.ModelAdmin):
inlines = [AttendanceInline]
def save_model(self, request, obj, form, change):
obj.save()
for user in User.objects.all():
obj.attendance_set.create(user=user, status='')
# you should consider a null field or a possible choice for "Undecided"
admin.site.register(Event, EventAdmin)
