Setting Up Logins For Users with Django - django

Question

I am trying to use Django's built in user authentication for login/allowing users to create an account and login. I think there's something wrong with my urls or where files are placed in the project. Can anyone help?
I know the login.html file is supposed to be inside a folder called 'registration.' I think the fact that my templates are then in a sub folder called 'capstone' might be causing issues. I just don't know how to point to the right file when someone clicks to login.
In urls.py under 'weather' I have the following. In two tutorials I saw it should say 'accounts/' but I'm a bit confused as to why.
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('capstone.urls')), # medium site says to do this
path('accounts/', include('django.contrib.auth.urls')),
] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
This is how my files are set up in Visual Studio Code:
Now under weather, I have:
Now under urls.py under capstone, I have:
router = routers.DefaultRouter()
router.register(r'locations', views.LocationViewSet)
urlpatterns = [
path('accounts/', include('django.contrib.auth.urls')),
path('api-auth/', include('rest_framework.urls',
namespace='rest_framework')),
path("", views.home, name="home"),
path("register", views.register, name="register"),
path("login", views.login_view, name="login"),
] + static(settings.STATIC_URL,
document_root=settings.STATIC_ROOT)
urlpatterns += static(settings.STATIC_URL,
document_root=settings.STATIC_ROOT)
urlpatterns += static(settings.MEDIA_URL,
document_root=settings.MEDIA_ROOT)
views.py:
def home(request):
return render(request, "capstone/home.html")
def login_view(request):
if request.method == "POST":
email = request.POST["email"]
password = request.POST["password"]
user = authenticate(request, username=email,
password=password)
# Check if authentication successful
if user is not None:
login(request, user)
return HttpResponseRedirect(reverse('home'))
else:
return render(request, "capstone/login.html", {
"message": "Invalid email and/or password."
})
else:
return render(request, "capstone/login.html")
def register(request):
if request.method == "POST":
email = request.POST["email"]
# Ensure password matches confirmation - this part works!
password = request.POST["password"]
confirmation = request.POST["confirmation"]
if password != confirmation:
return render(request, "capstone/signup.html", {
"message": "Passwords must match."
})
# Attempt to create new user
try:
User = get_user_model()
user = User.objects.create_user(email, email,
password)
user.save()
except IntegrityError as e:
print(e)
return render(request, "capstone/signup.html", {
"message": "Email address already taken."
})
login(request, user)
return HttpResponseRedirect(reverse("home"))
else:
return render(request, "capstone/signup.html")

Setting the path to accounts/ allows you to create a url such as <your_site_name>/accounts/login
https://docs.djangoproject.com/en/3.2/topics/auth/default/#module-django.contrib.auth.views
Basicaly the link shows you get the login/, logout/, and a bunch other urls/views for free. You can append names to the url making it longer if you would like...
Now Im not sure which app the url_conf is in, that calls path('accounts/', include('django.contrib.auth.urls')), but I'm guessing since you have the static_dir addition at the bottom, its the weather/settings.py urls conf.
In settings.py in the TEMPLATES settings. If APP_DIRS is True, (which is by default), Django will check the template directory which is inside app directory that the template is being called in. In your case, it will check the template directory in the weather app (which is your main app). You would need to change your directory heiarchy.
Using django.contrib.auth urls
weather
|
|--templates
|
|--registration
|
|--login.html
If you want to use the capstone app. Then you need to move the call
path('accounts/', include('django.contrib.auth.urls')) to the capstone app. At which point the URL will change to <your_site_name/capstone/accounts/login>.
=============================
Now you have a login_view instead, named login which is overriding the login view of django contrib, so your heirachy should resemble something like this.
capstone
|
|--templates
|
|--capstone
|
| -- login.html
Also FYI make sure to end your paths to the URL’s with “/“. Like “login” should be “login/“
