how to redirect different types of pages for different users after login in django

Question

I have created two different types of users - truck & company using Django. Here is my registration page of a user Registration Page

After registering, the data about whether the user is a truck or company will go to the database.

In my login page, only EmailID and Password are to be entered.

I would like to know how a user with a unique EmailID can redirects to a valid page based on the type of user.

I assume, Authentication and getting the data from POST request(in views.py ) to my login page isn't working properly. Please, someone help me fixing this.

here's my code:

views.py:

@csrf_protect
def login_view(request):
    title = "Login"
    if request.method == 'POST':
    email = request.POST.get('email', '')
    password = request.POST.get('password', '')
    user = auth.authenticate(username=email, password=password)
    form = LoginForm(data=request.POST)
    if form.is_valid():
        user_type = form.cleaned_data['Label']
        if user_type == 'Truck':
            return HttpResponseRedirect('/post_load/')
        elif user_type == 'Company':
            return HttpResponseRedirect('/live_deal/')
    else:
        form = LoginForm()

    return render(request, 'registration/login.html', {'form' : form, 'title': title})

urls.py:

url(r'^login/$', 'django.contrib.auth.views.login', {'authentication_form': LoginForm}),
url(r'^accounts/login/$', 'django.contrib.auth.views.login', {'authentication_form': LoginForm}),

forms.py:

class LoginForm(auth.forms.AuthenticationForm):

email = forms.EmailField(label=_("Email"),widget=forms.EmailInput)
CHOICES= (('Truck', 'Truck'),('Company', 'Company'),)
Label = forms.ChoiceField(choices=CHOICES, label='Label', widget=forms.RadioSelect())

login.html:

{%extends "registration/header.html"%}
{% block content %}
{% if form.errors %}
    <p>Your email and password didn't match. Please try again.</p>
{% endif %}

<form class="form-horizontal" method="post" action = "." >{%csrf_token%}
<div class="panel panel-default login">
            <div class="panel-heading">
                <span class="glyphicon glyphicon-lock"></span> Login</div>

</div>

Answer 1

Here's a better way to check that radio field in your views:-

user_type = form.cleaned_data['Label']
if user_type == 'truck':
   # send the user to truck page
else:
   # send the user to company page

A few more things - you don't really need to call that clean() method once you validate using is_valid() and you should move that authenticate() thing inside that POST section.
