Question

I’m trying to call a view directly from another (if this is at all possible). I have a view:

def product_add(request, order_id=None):
    # Works. Handles a normal POST check and form submission and redirects
    # to another page if the form is properly validated.

Then I have a 2nd view, that queries the DB for the product data and should call the first one.

def product_copy_from_history(request, order_id=None, product_id=None):
    product = Product.objects.get(owner=request.user, pk=product_id)

    # I need to somehow setup a form with the product data so that the first
    # view thinks it gets a post request. 
    2nd_response = product_add(request, order_id)
    return 2nd_response

Since the second one needs to add the product as the first view does it I was wondering if I could just call the first view from the second one.

What I’m aiming for is just passing through the request object to the second view and return the obtained response object in turn back to the client.

Any help greatly appreciated, critism as well if this is a bad way to do it. But then some pointers .. to avoid DRY-ing.

Thanx!

Gerard.

My god, what was I thinking. This would be the cleanest solution ofcourse:

def product_add_from_history(request, order_id=None, product_id=None):
    """ Add existing product to current order
    """
    order = get_object_or_404(Order, pk=order_id, owner=request.user)
    product = Product.objects.get(owner=request.user, pk=product_id)

    newproduct = Product(
                    owner=request.user,
                    order = order,
                    name = product.name,
                    amount = product.amount,
                    unit_price = product.unit_price,
                    )
    newproduct.save()
    return HttpResponseRedirect(reverse('order-detail', args=[order_id]) )
