      return render(request, context)


Configure url:

.. code-block:: python

  # apps/core/urls.py
  from django.urls import path

  from core import views

  app_name = "core"

  urlpatterns = [
      path("new", views.new, name="new"),
  ]

      form = UserCreationForm()
      if request.method == "POST" and not request.action:

        if form.is_valid():
            form.save()
            return PicometResponseRedirect(request, "/account")
      context["form"] = form
      return render(request, context)

  @template("pages/Blog")
  def blog(request, slug):
      blogs = Blog.objects.filter(slug=slug)
      if blogs.exists():

          return render(request, context)
      return PicometResponseRedirect(request, "/blogs")
