if request.env.user.premium_user == True:

    cPrice = request.env['product.template'].search([('id','!=',False)])

    cost_cp = {'costSP':cPrice}

    return request.render("shopping_cart.usertype",cost_cp)

I will get the following error

"'NoneType' object is not iterable" while evaluating
"keep('/shop/product/%s' % slug(product), page=(pager['page']['num'] if pager['page']['num']>1 else None))"
