Question

I am creating a little Django app with Users and I have created my own UserProfile model.. But I have some issues with my urls(atleast I think). I think the regular expressions I have used are wrong. Check it out:

the error I get:

ValueError at /usr/tony/

invalid literal for int() with base 10: 'tony'

My url:

url(r'^usr/(?P<username>\w+)/$', 'photocomp.apps.users.views.Userprofile'),

My view:

from django.shortcuts import render_to_response, get_object_or_404
from django.template import RequestContext
from django.contrib import auth
from django.http import HttpResponseRedirect
from photocomp.apps.users.models import UserProfile

def Userprofile(request, username):
    rc = context_instance=RequestContext(request)
    u = UserProfile.objects.get(user=username)
    return render_to_response("users/UserProfile.html",{'user':u},rc)

here is my model:

from django.db import models
from django.contrib.auth.models import User

class UserProfile(models.Model):
    user = models.ForeignKey(User, unique=True)
    first_name = models.CharField(max_length="30", blank=True)
    last_name = models.CharField(max_length="30", blank=True)
    email = models.EmailField(blank=True)
    country = models.CharField(blank=True,max_length="30")
    date_of_birth = models.DateField(null=True)
    avatar = models.ImageField(null=True, upload_to="/avatar")

Answer 1

u = UserProfile.objects.get(user__username=username)

It looks like you are searching for the username attribute of user. Foreign keys are spanned in django by double underscores.

Also .get() will throw a DoesNotExist exception it is advisable to wrap the query in try: except block so that it doesn’t 500 on the user.
https://docs.djangoproject.com/en/1.2/ref/exceptions/#objectdoesnotexist-and-doesnotexist

def Userprofile(request, username):
    rc = context_instance=RequestContext(request)
    try:
      u = UserProfile.objects.get(user__username=username)
    except UserProfile.DoesNotExist:
      # maybe render an error page?? or an error message at least to the user
      # that the account doesn't exist for that username?
    return render_to_response("users/UserProfile.html",{'user':u},rc)
