Hi,
I'm new to Django and just need some guidance.
Below is my attempt at creating a simple app that displays all transactions
and lists the grand total called 'points' for a particular user. Now the
following works and does just that, however, I'm not 100% if this is the
'correct' way nor really what a 'manager' is.
Could someone look at the following code and advice?
Many, many thanks O, and Happy Christmas everyone!
models.py
from django.db import models
from django.contrib.auth.models import User
class TransactionManager(models.Manager):
def Transaction_list(self,thisUser):
list = Transaction.objects.filter(user=thisUser)
return list
def points_total(self,thisUser):
return
Transaction.objects.filter(user=thisUser).aggregate(total_points=models.Sum('points'))
class Transaction (models.Model):
statusOptions = (
(0, 'Pending'),
(1, 'Added'),
(2, 'Deducted'),
(3, 'Processing'),
)
user = models.ForeignKey(User)
points = models.IntegerField(verbose_name=("Points"), default=0)
created = models.DateTimeField(("Created at"), auto_now_add=True)
updated = models.DateTimeField(verbose_name=("Updated at"),
auto_now=True)
status = models.IntegerField(default=0, choices=statusOptions)
objects = TransactionManager()
views.py
from django.template import RequestContext
from django.contrib.auth.decorators import login_required
from django.shortcuts import render_to_response
from points.models import Transaction
@login_required
def history(request):
thisPoints = Transaction.objects.Transaction_list(request.user)
totalPoints = Transaction.objects.points_total(request.user)
context = {'points':thisPoints,'totalPoints':totalPoints}
return render_to_response('points/history.html', context,
context_instance=RequestContext(request))
