'AnonymousUser' object has no attribute '_meta' error in Django login function

Question

I'm having problem in the built-in login function in Django.

Here is the views.py code:

def login_page(request):
    if request.method == 'POST':
        form = AuthenticationForm(data=request.POST) 
        if form.is_valid:
            user = form.get_user()
            login(request, user)    
            return redirect('index')
    else: 
        form = AuthenticationForm() 
    return render(request, 'login.html', {'form':form})

And below is my html code.

<form action="{% url 'login' %}" method="post">
        {% csrf_token %}
        {{ form }}
        <input type="submit" value="Log in">
</form>

As soon as I click the 'Log in' button, it gives an error that says: 'AnonymousUser' object has no attribute '_meta'

I don't see which part is wrong. I very much appreciate your help. :)

@kyore I am using a custom user model and this is the same error that pops up while serializing user object. Any tips? — Sahil

is_valid is not a property, it is a function. So you need to call it like this:

if form.is_valid():

Explanation: As you are not calling that function, the AuthenticationForm is not authenticating the user inside clean method. Hence you are not getting the User instance with form.get_user() method.
