i need to connect these two models each other. when someone goes to 127.0.0.1/blog/username (with or without login) all the data which are belong to user named 'username' must be there.
here is my models.py:
class Profile(models.Model):
slogan = models.TextField(blank=True)
twitter = models.CharField(max_length = 100,blank=True)
web_site = models.CharField(max_length=100,blank=True)
email = models.CharField(max_length = 100,blank=True)
def __unicode__(self):
return self.slogan
class Post(models.Model):
owner = models.ForeignKey(User)
title = models.CharField(max_length = 100)
body = models.TextField()
bodyPreview = models.TextField() #preview için body alanı
titlePreview = models.CharField(max_length=100) # preview için title alanı
slug = AutoSlugField(populate_from='title' ,unique=True)
posted = models.DateField(auto_now_add=True)
isdraft = models.BooleanField(default=False)
def __unicode__(self):
return self.title
#permalink
def get_absolute_url(self):
return ('view_blog_post',None,{'postslug':self.slug})
and my index view :
def index(request,username):
post_list = Post.objects.filter(owner__username=username).filter(isdraft=False).order_by("-posted")
p_index = Paginator(post_list,3) #anasayfa için pagination.[her sayfada 3 post]
page = request.GET.get('page')
try:
indexPag = p_index.page(page)
except PageNotAnInteger:
indexPag = p_index.page(1)
except EmptyPage:
indexPag = p_index.page(p_index.num_pages)
## i need to get user's profile datas here. ??
return render_to_response('index.html',
{'post_list':post_list,'p_index':indexPag,'profile':query},
context_instance = RequestContext(request))

Answer 1

I think you should change your Profile model and add a OneToOne relationship to the User model(for more info see here):
class Profile(models.Model):
user = models.OneToOneField(User)
...
class Posts(models.Model):
author = models.ForeignKey(User)
...
and then in your views you can do:
user = get_object_or_404(User, username=username)
post_list = Post.objects.filter(author=user).filter(isdraft=False).order_by("-posted")
return render_to_response('index.html',
{'post_list': post_list, 'user': user, ...}, ...)
And then in your template you are able to access the user's profile.More here
e.g {{user.get_profile.slogan}}

Answer 2

In your view:
def index(request, username):
user = User.objects.get(username=username)
return render(request, 'index.html', {'user':user})
In your template:
{{ user.post_set }}
and You will receive list of posts of current user.

Answer 3

The most natural way to achieve that is to add a OneToOne relation between your Profile model and the django's User model.
from django.contrib.auth.models import User
class Profile(models.Model):
user = models.OneToOneField(User)
# More fields
class Article(models.Model):
author = models.ForeignKey(User)
# More fields
This way, you can access the profile data through a User object. Would be something like this:
user = User.objecets.get(username=username)
profile = user.profile
More info about this, you can read the django model fields documentation here
and you can also see this cool answer about the diference between the ForeignKey with unique=True and the OneToOneField
I hope this helps
