Re: New to Django, sheet music organization site

Thank you very much! You have been very helpful. I have, however, run
into another problem.

When I try to access my Object, I get an error "invalid literal for
int() with base 10". I know it has something to do with ForeignKeys,
but cannot find how to fix it.

**models.py**------------------------------------------------------------------------------------------------------------------

from django.db import models

# Create your models here.

class Artist(models.Model):
name = models.CharField(max_length=100)
slug = models.SlugField(unique=True)

def __unicode__(self):
return self.name

class Album(models.Model):
name = models.CharField(max_length=200)
artist = models.ForeignKey(Artist)

def __unicode__(self):
return self.name

class Song(models.Model):
name = models.CharField(max_length=100)
artist = models.ForeignKey(Artist)
album = models.ForeignKey(Album)
date_added = models.DateField('date added')

def __unicode__(self):
return self.name

**views.py**------------------------------------------------------------------------------------------------------------------

from music.models import Song
from django.shortcuts import render_to_response

# Create your views here.

def index(request):
artist = Song.objects.all().order_by('name')
return render_to_response('music/index.html', {'artist': artist})

def artist(request, myartist):
myArgs = Song.objects.all().filter(artist=myartist)
return render_to_response('music/index.html', {'artist': myArgs})

Thanks
