Django routing/pathing to multiply apps-CodePudding

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)

CodePudding user response：

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.
