Register works but login doesn't for some reason even though I've rechecked the template tagging properly.
I'm using a custom login model, not using the admin authentication model.
this is the at basic_app/urls.py
from django.conf.urls import url
from basic_app import views
app_name = 'basic_app'
urlpatterns = [
url('register/',views.register,name='register'),
url('user_login/',views.user_loginPls,name='user_login'),
]
and code at base.html
<!DOCTYPE html>

I can't figure out this error, any help would be appreciated.
I'm running Django 2.0 btw
the error is in your login.html file.
In the form section, the action should take action="{% url 'user_login' %}" and not action="{% url 'basic_app/user_login' %}".
Hope this helps.

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

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)

login_register.html
{% extends 'main.html' %}

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;
}

<div class="home-container">

{% for i in sort_info %}

{% endfor %}
</div>
<div>
<h5>{{information_count}} devices registered</h5>
<hr>

<hr>
{% for information in information_search %}

<h3> view </h3>

This is the urls.py of the project

path('login/', auth_views.LoginView.as_view(template_name='blog/login.html'), name='login'),
path('logout/', auth_views.LogoutView.as_view(template_name='blog/logout.html'), name='logout'),
]
This is the form.py file:
from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm
class UserRegisterForm(UserCreationForm):
email = forms.EmailField()
class Meta:
model = User
fields = ['username', 'email', 'password1', 'password2']
You forgot to create a new form in forms.py, then also dont forget to enhance your login view.
You could try using this, adapted from the example in this tutorial:
from django.shortcuts import render, redirect
from django.contrib.auth import authenticate, login
from django.contrib.auth.forms import AuthenticationForm
def login(request):
if request.user.is_authenticated:
return redirect('/')
if request.method == 'POST':
username = request.POST['username']
password = request.POST['password']
user = authenticate(request, username=username, password=password)
if user is not None:
login(request, user)
return redirect('/')
else:
form = AuthenticationForm(request.POST)
return render(request, 'blog/login.html', {'form': form, 'title': 'Login'})
else:
form = AuthenticationForm()
return render(request, 'blog/login.html', {'form': form, 'title': 'Login'})
To use that you would have to change the login line in your urls.py to this:
path('login/', blog_views.login, name='login'),
