page with unique url and users content per user - django

Question

I'm trying to build a app in which every user has his own database content, but on one page/url some (chosen) database content is listed and publicly visible.
I did a lot of research, but cannot come up with the logic how this works. I have a username in the URL, but when I change it to other users names, the content is not changing... What step do I miss here?
views.py
def public_view(request, username):
if request.user.is_authenticated():
info = Profile.objects.filter(user=request.user)
instance = Parent.objects.filter(user=request.user)
childs = Child.objects.filter(user=request.user)
u = MyUser.objects.get(username=username)
context = {
'info': info,
'instance': instance,
'childs': childs,
'u': u,
}
return render(request, 'public/public_home.html', context)
else:
raise Http404
urls.py
from django.conf.urls import url
from django.contrib import admin
from . import views
urlpatterns = [
url(r'^user/(?P<username>\w+)/$', views.public_view, name='public_view'),
]

Answer 1

In your view you get data for current user using request.user in querysets.You should change your queryset's argument t u object:
def public_view(request, username):
if request.user.is_authenticated():
u = MyUser.objects.get(username=username)
info = Profile.objects.filter(user=u)
instance = Parent.objects.filter(user=u)
childs = Child.objects.filter(user=u)
context = {
'info': info,
'instance': instance,
'childs': childs,
'u': u,
}
return render(request, 'public/public_home.html', context)
else:
raise Http404
