Django routing/pathing to multiply apps - django

Question

Hi i know there is many of these asking about routing from a veiw to a new app in django. I have looked at a lot of them. And figured out to use app_name = 'name' and to use named routes for my html templates makes everything easier for sure. When i try to use a app_name:named-route i get this :
ValueError at /recipedashboard
The view recipeApp.views.dashboard didn't return an HttpResponse object. It returned None instead.
I have gotten the name_app:named-route to send me to the second app, but how do i pass the session to the new app?
userApp veiws:
from django.shortcuts import render, redirect
from django.contrib import messages
from .models import User as LoggedUser
# Create your views here.
def index(request):
return render(request, 'index.html')
def register(request):
if request.method == "GET":
return redirect('/')
errors = LoggedUser.objects.validate(request.POST)
if len(errors) > 0:
for er in errors.values():
messages.error(request, er)
return redirect('/')
else:
new_user = LoggedUser.objects.register(request.POST)
request.session['user_id'] = new_user.id
messages.success(request, "You have successfully registered")
return redirect('/success')
def login(request):
if request.method == "GET":
return redirect('/')
if not LoggedUser.objects.authenticate(request.POST['email'],
request.POST['password']):
messages.error(request, "Invalid Email/Password")
return redirect('/')
user = LoggedUser.objects.get(email=request.POST['email'])
request.session['user_id'] = user.id
messages.success(request, "You have successfully logged in!")
return redirect('/success')
def logout(request):
request.session.clear()
return redirect('/')
def success(request):
if 'user_id' not in request.session:
return redirect('/')
context = {
'user' : LoggedUser.objects.get(id=request.session['user_id'])
}
return redirect("recipe:recipe-dashboard")
recipeApp urls.py:
from django.urls import path
from . import views as recipeViews
app_name ='recipe'
urlpatterns = [
path('dashboard', recipeViews.dashboard, name= "recipe-dashboard" )
]
recipeApp.Views :
from django.shortcuts import render, redirect
from userApp.models import User as LoggedUser
# Create your views here.
def dashboard(request):
if 'user_id' not in request.session:
return redirect('/')
user = LoggedUser.objects.get(id=request.session['user_id'])
context = {
'user' : user
}
render (request, 'dashboard.html', context)

Answer 1

Your dashboard view is not returning anything.
You need to return the results of render. Like
from django.shortcuts import render, redirect
from userApp.models import User as LoggedUser
# Create your views here.
def dashboard(request):
if 'user_id' not in request.session:
return redirect('/')
user = LoggedUser.objects.get(id=request.session['user_id'])
context = {
'user' : user
}
return render (request, 'dashboard.html', context)
There is no need to deal with passing a session. The framework will handle that for you if the apps are all under the same project.
