[FIXED] login_required Django redirect next not working

Issue

Hello. I try to redirect user to the page he wants before he login, by login_required but the page doesn't redirecting! I have searched a lot but I found nothing. Here my main codes for login_required: I summarized them to the related subject. If need to add something else, tell me. Thank you in advance.

VIEW:

from django.contrib.auth.decorators import login_required

def user_login(request):
    next_url = request.GET.get('next')
    print(next_url)
    if request.method == 'POST':
        form = UserLoginForm(request.POST)
        if form.is_valid():
            cd = form.cleaned_data
            user = authenticate(request, username=cd['username'], password=cd['password'])
            if user is not None:
                login(request, user)
                messages.success(request, 'Login Successful', extra_tags='success')
                if next_url:
                    return redirect(next_url)
                return redirect('post:all_posts')
            else:
                messages.error(request, 'Wrong Username Or Password', extra_tags='warning')
    else:
        form = UserLoginForm()
    return render(request, 'account/login.html', {'form': form})

@login_required
def dashboard(request, user_id):
    users = get_object_or_404(User, id=user_id)
    posts = Post.objects.filter(user=users)
    context = {'user': users, 'posts': posts}
    return render(request, 'account/dashboard.html', context=context)

Login View:

{% extends 'base.html' %}

{% block content %}
    <form action="." method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Login" class="btn btn-primary">
    </form>

Solution

As you see, The next query is there in GET request but when the form is submitted URL queries are not being passed. You can see that in the image corresponding to POST request. You may need to add the next url to the login form and access the next url from POST data.

Add a hidden field in your login form

{% extends 'base.html' %} 
{% block content %} 
<form action="." method="post"> 
    {% csrf_token %} 
    {{ form.as_p }} 
    <input type="hidden" name="next" value="{{ request.GET.next }}" />
    <input type="submit" value="Login" class="btn btn-primary"> 
</form> 
{% endblock content %}

{{ request.GET.next }} is accessible by the request template context processors which is already there in the settings.TEMPLATES

And in your user_login access the next url from request.POST

def user_login(request): 
    if request.method == 'POST':
        next_url = request.POST.get('next')
        # code
