is this (online tutorial) code calling a view from a view?

[Andrew Taylor]

Hi,

I've been following an online tutorial but been debugging. I've traced my 
issue to this line in the view function below:

return category(request, category_name_url)


Is this view effectively calling another view directly without going via 
the urls file (in the exception case)? If so can you advise me if this is 
good or bad practice?

Thanks,


Andy



from rango.forms import PageForm
def add_page(request, category_name_url):
    context = RequestContext(request)

    category_name = decode_url(category_name_url)
    if request.method == 'POST':
        form = PageForm(request.POST)

        if form.is_valid():
            # This time we cannot commit straight away.
            # Not all fields are automatically populated!
            page = form.save(commit=False)

            # Retrieve the associated Category object so we can add it.
            # Wrap the code in a try block - check if the category actually 
exists!
            try:
                cat = Category.objects.get(name=category_name)
                page.category = cat
            except Category.DoesNotExist:
                # If we get here, the category does not exist.
                # We render the add_page.html template without a context 
dictionary.
                # This will trigger the red text to appear in the template!
                return render_to_response('rango/add_page.html', {}, context)

            # Also, create a default value for the number of views.
            page.views = 0

            # With this, we can then save our new model instance.
            page.save()

            # Now that the page is saved, display the category instead.
            return category(request, category_name_url)
        else:
            print form.errors
    else:
        form = PageForm()

    return render_to_response( 'rango/add_page.html',
            {'category_name_url': category_name_url,
             'category_name': category_name, 'form': form},
             context)
