I'm using the Django authentication with my login form in my template, after i pressed the login button on the form the page refreshed but doesn't log me in and doesn't show the {{context}} error in the template.

My view:

def login_view(request):

    if request.method == 'POST':

        all_categories = Categories.objects.all()

        all_websites = Website.objects.all()

        all_discounts = Discount.objects.order_by('-id')

        username = request.POST.get('username')

        password = request.POST.get('password')

        user = authenticate(request, username=username, password=password)

        if user is not None:

            login(request, user)

            return redirect('/',categories=all_categories,websites=all_websites,discounts=all_discounts)

        else:

            context = 'wrong username or password'

            all_categories = Categories.objects.all()

            all_websites = Website.objects.all()

            all_discounts = Discount.objects.order_by('-id')

            return redirect('/',categories=all_categories,websites=all_websites,discounts=all_discounts,context=context)

My form (header.html)

<div class="col-md-3 top-info-cart text-right mt-lg-4">

                    {% if user.is_authenticated %}

                        <p>Welcome, {{ user.username }}.</p>

                        <p><a href="{% url 'frontend:logout' %}">logout</a></p>

                    {% else %}

                        <ul class="cart-inner-info">

                        <li class="button-log">

                            <a class="btn-open" href="#">

                                <span class="fa fa-user" aria-hidden="true"></span>

                            </a>

                        </li>

                        </ul>

                        <p>{{context}}</p>

                    {% endif %}



                    <!---->

                    <div class="overlay-login text-left">

                        <button type="button" class="overlay-close1">

                                    </div>

                                    </div>

                                    <button type="submit" class="btn btn-primary submit mb-4" value="Login">Sign In</button>

                                    <p>Don't have an account? <a href="{% url 'frontend:signup' %}" style="color: orange;">SIGN UP </a></p>

                                </form>

                            </div>

                            <!---->

                        </div>

                    </div>

And my urls.py:

from  django.urls import path

from .import views

app_name = 'frontend'

urlpatterns = [

    #index

    path('',views.index, name='index'),

     #/discount/id

    path('<id>/',views.single,name='single'),

    #/category/category_name

    path('category/<name>',views.category,name='category'),

    #/signup

    path('signup',views.signup,name='signup'),

    #/logout

    path('logout',views.logout,name='logout'),

    #/login

    path('login',views.login_view,name='login')

]

It's because of my authentication is wrong or my view function ? i been trying to fix this but still haven't figure it out. Hope someone can help me :)

Try changing your form's action to action="":

<form action="" method="post">

The way you have it set right now what I think is happening is your form is just re rendering the login view.

Add a form to your view:

def login_view(request):

    if request.method == 'POST':

        form = YourLoginForm(data=request.POST)

        if form.is_valid():

            ...

and you can just render your form in the template:

<form action="" method="post">



 {{ form.as_p }}

 <input type="submit" value="submit"/>



</form>

Also a potential problem is your view's redirect:

return redirect('/'

In my app this would redirect me to my login page because my home view redirects to my login page. Maybe try redirecting to another view upon successful login.
