Have you tried the above solutions.
P.S. I have no experience in hacking the Admin Interface, I have made
my own Admin pages using the above process

Django Sum all values with a distinct ForeignKey ID & zip them with fields from related table

[Gramware]

I would like to perform something similar to
http://stackoverflow.com/questions/861310/summing-the-values-from-the-2nd-table-based-on-id-of-the-1st-table
(ie get the sum of distinct event amounts in a payment table then
group the payments by event details and total money paid for them.
Also getting users and what they have paid for an event will be done)
in Django using PostgreSQL.

My models are as below:

class UserProfile(User):
onames = models.CharField(max_length=30, blank=True)
phoneNumber = models.CharField(max_length=15, blank=True)
regNo = models.CharField(max_length=15)
designation =
models.CharField(max_length=3,choices=DESIGNATION_CHOICES,
default='MEM')
image = models.ImageField(max_length=100,upload_to='photos/%Y/%m/
%d', blank=True, null=True, default='photos/2010/03/placeholder.jpg')
course = models.CharField(max_length=30, blank=True, null=True)
timezone = models.CharField(max_length=50, default='Africa/
Nairobi')
smsCom = models.BooleanField()
mailCom = models.BooleanField()

class Payments(models.Model):
username = models.ForeignKey(UserProfile, related_name='payer')
receiptNo = models.CharField(max_length=30, primary_key=True)
particulars = models.CharField(max_length=50)
date = models.DateField(auto_now_add=True)
amount = models.FloatField(max_length=99, blank=True)
eventID = models.ForeignKey('events', null=True, blank=True)
receiver = models.ForeignKey(UserProfile,
related_name='receiver')
deleted = models.BooleanField()

class events(models.Model):
eventName  = models.CharField(max_length=100)
eventID =  models.AutoField(primary_key=True)
details = models.TextField()
attendanceFee = models.FloatField(max_length=99)
date = models.DateField()
username = models.ManyToManyField(UserProfile,
related_name='user')
eventposter = models.ForeignKey(UserProfile,
related_name='event_poster')
deleted = models.BooleanField()

I do not fully understand your question, but if you would like to
Iterate (loop over) 2 values in your template at  the same time, you
can use the zip command like blow

In your views.py

peo = People.objects.all()
pub=Publications.objects.all()

render_to_response(template.html, {'tables':zip(peo,pub)})

in your template (template.html)

{% for pe, pu in tables %}
{{pe.field1}} {{pu.field1}}
{% endfor %}

I am assuming that for each record in people, there is a matching one
in publications

Why not use a ForeignKey?

I do not fully understand your question , but if you want to Iterate
over both tables  at the same time, you can do the following . This
will use the zip command to pack your variables

in view.py

peo = People.objects.all()
pub = Publication.objects.all()

render_to_response(template.html, {'tables':zip(peo, pub)} )

in your template(template.html)

{% for t in tables %}
{{t.field1}} {{t.field2}}
{% endfor %}

Why not use Foreign Key or ManyToMany field

Template-loader postmortem

Django tried loading these templates, in this order:
Using loader django.template.loaders.filesystem.load_template_source:
/home/projects/acms/acms_templates/admin/login.html (File does not
exist)
Using loader
django.template.loaders.app_directories.load_template_source:
Using loader django.template.loaders.eggs.load_template_source:





my url.py is

from django.conf.urls.defaults import *
from acms.views import hello, current_datetime, hours_ahead, login
import os.path

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
('^hello/$', hello),
('^log_in/$', login),
('^time/$', current_datetime),
(r'^admin/', include(admin.site.urls)),
(r'^time/plus/(\d{1,2})/$', hours_ahead),
(r'^media/(?P.*)', 'django.views.static.serve',
{'document_root':
'settings.MEDIA_ROOT'}),




and views.py

from django.shortcuts import render_to_response
from django.http import HttpResponse
import datetime

def hello(request):
return HttpResponse("Hello world")


def current_datetime(request):
now = datetime.datetime.now()
return render_to_response('base.html', {'current_date': now})


def hours_ahead(request, offset):
try:
offset = int(offset)
except ValueError:
raise Http404()
dt = datetime.datetime.now() + datetime.timedelta(hours=offset)
html = " In %s hour(s),  it will be %s. " %
(offset, dt)
return HttpResponse(html)


def login(request):
return render_to_response('login.html', {'': locals()})



What could be the issue, since I am following the Django book? Thanks.
