I can't create login in django 1.10.1 version

Question

I know it is basic to create login User Authentication. And I am a newbie here in using Django.

I have a problem in creating User Authentication:

Views.py

def Logins(request):
if request.method == 'POST':
    username = request.POST['username']
    password = request.POST['password']
    user = authenticate(username=username, password=password)
    if user is not None and user.is_active:
        login(request, user)
        return HttpResponseRedirect('music/login')
    return HttpResponseRedirect('music/login')
form = Userlogin
return render(request, 'music/login.html', {'Login_form': Userlogin})

urls.py url(r'^login/$', views.Logins, name='login'),

It shows It shows MultiValueDictKeyError at /music/login/. "'username'" Request Method: POST Request URL: http://127.0.0.1:8000/music/login/ Django Version: 1.10.4 Exception Type: MultiValueDictKeyError Exception Value:
"'username'"

login.html

{% block body %}
{% if form.errors %}
<p>Something is wrong</p>
{% endif %}

<form action="" method="post">
    {% csrf_token %}
    <label for="email">Login:</label>
    <label for="password">Password:</label>
    <input type="password" name="password" value="" id="username">

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

</form>
{% endblock %}

Thanks in advance.

Answer 1

The MultiValueDictKeyError seems to be because request.POST['username'] does not exist.

Add a username field in your login form.

<form action="" method="post">
    {% csrf_token %}
    <label for="username">Username:</label>
    <input type="text" name="username">
    <label for="email">Login:</label>
    <label for="password">Password:</label>
    <input type="password" name="password" value="" id="username">
    <input type="submit" value="login" />

</form>

Answer 2

request.POST is a dictionary. You should be doing it this way:

username = request.POST.get('username', None)
password = request.POST.get('password', None)
