at django login my request.POST.get data are all empty, I struggle with what I missed there

[Sabine Maennel]

This is my login view:

def login_view(request,template_name='userauth/login.html'):

    if request.method == 'POST':

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

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

        print username

        print password

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

        if user is not None:

            if user.is_active:

                login(request, user)

                next_page = reverse('public:courselist')

            else:

                next_page = reverse('userauth:login')

                messages.error(request, "Ihr Account wurde deaktiviert. Bitte nehmen Sie Kontakt zu uns auf, wenn Sie Ihnen wieder aktivieren wollen.")

        else:

            next_page = reverse('userauth:login')

            messages.error(request, u'Ung\u00FCltiges Login')

    else:

        dictionary = {'form': form }

        return render_to_response('userauth/login.html', dictionary,  context_instance=RequestContext(request))

    return HttpResponseRedirect(next_page)

And this is my form:

from django import forms

class LoginForm(forms.Form):

    username = forms.CharField(

        max_length=100,

        widget=forms.TextInput,

        required=False,

        label="",

    )

    password = forms.CharField(

        max_length=100,

        widget=forms.TextInput,

        required=False,

        label="",

    )

I think I need to tell Django somehow about the form, but I do need really know where? Can someone please help me with figuring this out? When I print out the username and password they are both None. 

  Thanks in advance

Hi Sabine,

Your code looks good. Can you post you template code?

Why are you not using form `is_valid`? [0]

What version of Django are you using? You can be facing that your
request.POST is empty! [1]

This may be not what you are looking for but you can use Django
Authentication System [2]

Thank you Alejandro, it must be the template somehow: I had a seperate login form: 

{% extends "base/base.html" %}

{% load crispy_forms_tags %}

{% block head_content %}

    <div id="heading" class="jumbotron">

<div class ="container">

<div class ="row">

        <h2>Anmeldung bei Netteachers</h2>

</div></div>

    </div>

{% endblock %}

{% block main_content %}

{% if form.errors %}

<p>Your username and password didn't match. Please try again.</p>

{% endif %}

<div class ="container">

<div class ="row">

     <div class="col-md-6 col-lg-6 col-sm-6">

        <form id="login_form" method="post" action="{% url 'userauth:login' %}">

            {% form crispy %}

            {% csrf_token %}

           <button type="submit" class="btn btn-success">Anmelden</button>  

      </form>

     </div>

     <div class="col-md-6 col-lg-6 col-sm-6">

         <h2>Eine Baustelle</h2>

         Derzeit werden logins nur für Administratoren verteilt. Netteachers ist noch in der Aufbauphase.

     </div>

</div>

</div>

{% endblock %}

This did not work. Forms.py is this:

from django import forms

class LoginForm(forms.Form):

    username = forms.CharField(

        max_length=100,

        widget=forms.TextInput,

        required=False,

        label="",

    )

    password = forms.CharField(

        max_length=100,

        widget=forms.TextInput,

        required=False,

        label="",

    )

I then put the form back in the navigation bar, where it did work. I will check out your links. I am still a little confused by the formhandling overall.

    Thanks a lot für your very valuable input.

Use a login view like this:

@sensitive_post_parameters('password')
def login_view(request):
    form = LoginForm(initial={'email': request.order.email})
    if request.POST.get('login'):
        form = LoginForm(data=request.POST)
        if form.is_valid():
            if user.is_active:
                auth.login(request, form.user)
                return redirect('public:courselist')
            else:

                messages.error(request, "Ihr Account wurde deaktiviert. Bitte nehmen Sie Kontakt zu uns auf, wenn Sie Ihnen wieder aktivieren wollen.")

                return redirect('userauth:login')
    return render(request, 'userauth/login.html', {'form': form})

and add a clean() method to your form like this:

    def clean(self):
        if self.cleaned_data.get('username') and self.cleaned_data.get('password'):
            self.user = authenticate(username=self.cleaned_data['username'], password=self.cleaned_data['password'])
            if self.user is None:
                raise forms.ValidationError('Please enter a correct username and password.')
            elif not self.user.is_active:  # or leave this out and handle inactive case in your view above.
                raise forms.ValidationError('This account is inactive.')
        return self.cleaned_data
