I'm working on a platform for online labs registration for my university.
Login View [project views.py]
from django.http import HttpResponse, HttpResponseRedirect, Http404
from django.
shortcuts import render_to_response
from django.template import RequestContext
from django.contrib import auth
def index(request):
return render_to_response('index.html', {}, context_instance = RequestContext(request))
def login(request):
if request.method == "POST":
post = request.POST.copy()
if post.has_key('username') and post.has_key('password'):
usr = post['username']
pwd = post['password']
user = auth.authenticate(username=usr, password=pwd)
if user is not None and user.is_active:
auth.login(request, user)
if user.get_profile().is_teacher:
return HttpResponseRedirect('/teachers/'+user.username+'/')
else:
return HttpResponseRedirect('/students/'+user.username+'/')
else:
return render_to_response('index.html', {'msg': 'You don\'t belong here.'}, context_instance = RequestContext(request)
return render_to_response('login.html', {}, context_instance = RequestContext(request))
def logout(request):
auth.logout(request)
return render_to_response('index.html', {}, context_instance = RequestContext(request))
URLS
#========== PROJECT URLS ==========#
urlpatterns = patterns('',
(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT }),
(r'^admin/', include(admin.site.urls)),
(r'^teachers/', include('diogenis.teachers.urls')),
(r'^students/', include('diogenis.students.urls')),
(r'^login/', login),
(r'^logout/', logout),
(r'^$', index),
)
#========== TEACHERS APP URLS ==========#
urlpatterns = patterns('',
(r'^(?P<username>\w{0,50})/', labs),
)
The login view basically checks whether the logged in user is_teacher [UserProfile attribute via get_profile()] and redirects the user to his profile.
Labs View [teachers app views.py]
from django.http import HttpResponse, HttpResponseRedirect, Http404
from django.
shortcuts import render_to_response
from django.template import RequestContext
from django.contrib.auth.decorators import user_passes_test
from django.contrib.auth.models import User
from accounts.models import *
from labs.models import *
def user_is_teacher(user):
return user.is_authenticated() and user.get_profile().is_teacher
@user_passes_test(user_is_teacher, login_url="/login/")
def labs(request, username):
q1 = User.objects.get(username=username)
q2 = u'%s %s' % (q1.last_name, q1.first_name)
q2 = Teacher.objects.get(name=q2)
results = TeacherToLab.objects.filter(teacher=q2)
return render_to_response('teachers/labs.html', {'results': results}, context_instance = RequestContext(request))
I'm using @user_passes_test decorator for checking whether the authenticated user has the permission to use this view [labs view].
The problem I'm having with the current logic is that once Django authenticates a teacher user he has access to all teachers profiles basically by typing the teachers username in the url.
Once a teacher finds a co-worker's username he has direct access to his data.
Any suggestions would be much appreciated.
