request.user.is_authenticated does not work after changing urls - django

Question

So my code looked like this at first:
views.py
from django.shortcuts import render, redirect
from django.http import HttpResponse
from .models import Information
from django.db.models import Q
from django.contrib import messages
from django.contrib.auth import authenticate, login, logout
from .forms import MyForm
# rooms = [
# {'id': 1, 'name': 'Lets learn python!'},
# {'id': 2, 'name': 'Design with me'},
# {'id': 3, 'name': 'Frontend developers'},
# ]
def home(request):
q = request.GET.get('q') if request.GET.get('q') !=None else ''
information_search = Information.objects.filter(
Q(host__icontains=q) |
Q(hostname__icontains=q) |
Q(port__icontains=q) |
Q(platform__icontains=q) |
Q(username__icontains=q) |
Q(password__icontains=q) |
Q(groups__icontains=q)
)
sort_info = []
informations = Information.objects.all()
for i in informations:
if i.groups not in sort_info:
device_group = i.groups
sort_info.append(device_group)
information_count=information_search.count()
context = {'informations':informations, 'information_search':information_search, 'information_count':information_count, 'sort_info':sort_info}
return render(request, 'polls/home.html', context)
def view_data(request, pk):
information = Information.objects.get(id=pk)
context = {'information':information}
return render(request, 'polls/view_data.html', context)
def loginPage(request):
if request.method == 'POST':
username = request.POST.get('username')
password = request.POST.get('password')
try:
user = User.objects.get(username=username)
except:
messages.error(request, 'User does not exist')
user = authenticate(request, username=username, password=password)
if user is not None:
login(request, user)
return redirect('home')
else:
messages.error(request, "Username or password does not exist")
context = {}
return render(request, 'polls/login_register.html', context)
def logoutUser(request):
logout(request)
return redirect('home')
def edit_data(request, pk):
information = Information.objects.get(id=pk)
form = MyForm(instance=information)
if request.method == 'POST':
form = MyForm(request.POST, instance=information)
if form.is_valid():
form.save()
return redirect('home')
context = {'form': form}
return render(request, 'polls/room_form.html', context)
def delete_data(request, pk):
information = Information.objects.get(id=pk)
if request.method == 'POST':
information.delete()
return redirect('home')
return render(request, 'polls/delete.html', {'obj': information})
def my_form(request):
if request.method == "POST":
form = MyForm(request.POST)
if form.is_valid():
form.save()
return redirect('home')
else:
form = MyForm()
return render(request, 'polls/room_form.html', {'form': form})
urls.py
from django.urls import path
from . import views
urlpatterns = [
path('login/', views.loginPage, name="login"),
path('logout/', views.logoutUser, name="logout"),
path('', views.home, name='home'),
path('view_data/<str:pk>/', views.view_data, name = "view_data"),
path('edit_data/<str:pk>/', views.edit_data, name = "edit_data"),
path('host/', views.my_form, name='my_form'),
path('delete/<str:pk>/', views.delete_data, name='delete_data')
]
login_register.html
{% extends 'main.html' %}
{% block content %}
<div>
<form method="POST" action="">
{% csrf_token %}
<label>Username:</label>
<input type="text" name="username" placeholder="Enter Username" />
<label>Password:</label>
<input type="password" name="password" placeholder="Enter Password">
<input type="submit" value="login">
</form>
</div>
{% endblock content %}
I wanted to change the authentication system so that the home view is only returned if the user is logged in. I was able to show home view after the user logs in by making small changes to urls.py and login_register.html as follows:
views.py
from django.shortcuts import render, redirect
from django.http import HttpResponse
from .models import Information
from django.db.models import Q
from django.contrib import messages
from django.contrib.auth import authenticate, login, logout
from .forms import MyForm
# rooms = [
# {'id': 1, 'name': 'Lets learn python!'},
# {'id': 2, 'name': 'Design with me'},
# {'id': 3, 'name': 'Frontend developers'},
# ]
def home(request):
q = request.GET.get('q') if request.GET.get('q') !=None else ''
information_search = Information.objects.filter(
Q(host__icontains=q) |
Q(hostname__icontains=q) |
Q(port__icontains=q) |
Q(platform__icontains=q) |
Q(username__icontains=q) |
Q(password__icontains=q) |
Q(groups__icontains=q)
)
sort_info = []
informations = Information.objects.all()
for i in informations:
if i.groups not in sort_info:
device_group = i.groups
sort_info.append(device_group)
information_count=information_search.count()
context = {'informations':informations, 'information_search':information_search, 'information_count':information_count, 'sort_info':sort_info}
return render(request, 'polls/home.html', context)
def view_data(request, pk):
information = Information.objects.get(id=pk)
context = {'information':information}
return render(request, 'polls/view_data.html', context)
def loginPage(request):
if request.method == 'POST':
username = request.POST.get('username')
password = request.POST.get('password')
try:
user = User.objects.get(username=username)
except:
messages.error(request, 'User does not exist')
user = authenticate(request, username=username, password=password)
if user is not None:
login(request, user)
return redirect('home')
else:
messages.error(request, "Username or password does not exist")
context = {}
return render(request, 'polls/login_register.html', context)
def logoutUser(request):
logout(request)
return redirect('home')
def edit_data(request, pk):
information = Information.objects.get(id=pk)
form = MyForm(instance=information)
if request.method == 'POST':
form = MyForm(request.POST, instance=information)
if form.is_valid():
form.save()
return redirect('home')
context = {'form': form}
return render(request, 'polls/room_form.html', context)
def delete_data(request, pk):
information = Information.objects.get(id=pk)
if request.method == 'POST':
information.delete()
return redirect('home')
return render(request, 'polls/delete.html', {'obj': information})
def my_form(request):
if request.method == "POST":
form = MyForm(request.POST)
if form.is_valid():
form.save()
return redirect('home')
else:
form = MyForm()
return render(request, 'polls/room_form.html', {'form': form})
login_register.html
{% extends 'main.html' %}
{% block content %}
<div>
<form method="POST" action="home/">
{% csrf_token %}
<label>Username:</label>
<input type="text" name="username" placeholder="Enter Username" />
<label>Password:</label>
<input type="password" name="password" placeholder="Enter Password">
<input type="submit" value="login">
</form>
</div>
{% endblock content %}
However the bar at navbar.html which shows logout option if the user is logged in stops working..
navbar.html
<a href="/polls">
<h1>LOGO</h1>
</a>
<form method="GET" action="{% url 'home' %}">
<input type="text" name="q" placeholder="Search Devices...">
</form>
{% if request.user.is_authenticated %}
Logout
{% else %}
Login
{% endif %}
<hr>
navbar is included in main.html as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>StudyBud</title>
</head>
<body>
{% include 'navbar.html' %}
{% block content %}
{% endblock %}
</body>
</html>
and main.html is extended by other templates. Here main.html and navbar.html are stored in the templates folder of the root directory while other templates are in the 'polls' app folder.
If it helps here are my other files.
models.py
from django.db import models
from django.contrib.auth.models import User
class Information(models.Model):
host = models.CharField(max_length=200, null=True, blank=False)
hostname = models.CharField(max_length=200, null=True, blank=False)
port = models.IntegerField()
platform = models.CharField(max_length=200, null=True, blank=False)
username = models.CharField(max_length=200, null=True, blank=False)
password = models.CharField(max_length=200, null=True, blank=False)
groups = models.CharField(max_length=200, null=True, blank=False)
def __str__(self):
return self.host
Here is home.html which extends main.html and is supposed to show the logout bar.
{% extends 'main.html' %}
{% block content %}
<h2>Inventory Management</h2>
<style>
.home-container{
display: grid;
grid-template-columns: 1fr 3fr;
}
</style>
<div class="home-container">
<div>
<h3>Browse Groups</h3>
<hr>
{% for i in sort_info %}
<div>
{{i}}
<br><br>
</div>
{% endfor %}
</div>
<div>
<h5>{{information_count}} devices registered</h5>
<hr>
Add Device
<hr>
{% for information in information_search %}
<span>#{{information.host}}</span>
<h3> view </h3>
Edit
Delete
<hr>
{% endfor %}
</div>
</div>
{% endblock content %}
</div>
Any insight please? I am a beginner and I was trying to make changes and implement my own features in the code i followed through a tutorial.
