TypeError: Init Only takes 1 positional Argument

I am using Class Based Views to render my templates. Here is my code so far:

Views.py:

class CashFlowView(TemplateView):
    template_name = "visualization/cash_flow.html"

    def get_context_data(self, **kwargs):
        context = super(CashFlowView, self).get_context_data(**kwargs)
        return context

    def get(self, request, *args, **kwargs):
        context = self.get_context_data(**kwargs)
        return self.render_to_response(context)

    def render_to_response(self, context, **response_kwargs):
        response_kwargs.setdefault('content_type', self.content_type)
        return self.response_class(
            request=self.request,
            template=self.get_template_names(),
            context=context,
            using=self.template_engine,
            **response_kwargs
        )

urls.py:

from django.conf.urls import url
from django.contrib import admin
from .views import CashFlowView

urlpatterns = [
    url(r'cash-flow', CashFlowView, name='cashflowView')
]

As you can see I am using the templateView but I get this a weird init error. Any ideas?:

Internal Server Error: /visualization/cash-flow

You need to pass your TemplateView using its as_view method:

urlpatterns = [
    url(r'cash-flow', CashFlowView.as_view(), name='cashflowView')
]
