How to pass database queryset objects from class based views(class SignUp(generic.CreateView)) to templates in Django

views.py

from django.shortcuts import render
from django.urls import reverse_lazy
from django.views import generic
from .forms import CustomUserCreationForm

class SignUp(generic.CreateView):
    form_class = CustomUserCreationForm
    success_url = reverse_lazy('login')
    template_name = 'signup.html'

urls.py

urlpatterns = [
    url(r'signup/', views.SignUp.as_view(), name='signup'),
    url(r'^$', TemplateView.as_view(template_name='home.html'), name='home'),
]

To pass context, you can write

context_object_name = 'username'

Now think like you are making a To Do app and want to print the Tasks as per their You can then do the following inside your class based view,

def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['tasks'] = context['tasks'].filter(user=self.request.user)
        context['count'] = context['tasks'].count()

In this way, you can write the database queryset in class based views.

If you want a perfect guide or source code to learn the django authentication i.e. login and logout user functions, I suggest you to go once through this tutorial, It is a todo list app which will cover your doubts

To Do list app with django authentication and queryset in class based views

The sourcecode for the above is here:

You need to override get_context_data method in SignUp class, like this:

class SignUp(generic.CreateView):
    form_class = CustomUserCreationForm
    success_url = reverse_lazy('login')
    template_name = 'signup.html'

    def get_context_data(self, **kwargs):
       context = super(SignUp, self).get_context_data(**kwargs)
       context['your_qset'] = YourModel.objects.all()
       return context

and use it in template:

{% for obj in your_qset %}
   {{ obj }}
{% endfor %}
