NAME

Dancer::Plugin::Interchange6::Cart

DESCRIPTION

Extends Interchange6::Cart to tie cart to Interchange6::Schema::Result::Cart.

ATTRIBUTES

See "ATTRIBUTES" in Interchange6::Cart for a full list of attributes inherited by this module.

database

The database name as defined in the Dancer::Plugin::DBIC configuration.

Attribute is required.

sessions_id

Extends inherited sessions_id attribute.

Attribute is required.

METHODS

See "METHODS" in Interchange6::Cart for a full list of methods inherited by this module.

get_sessions_id

BUILDARGS

Sets default values for name, database and sessions_id if not given and loads other attribute values from DB cart. If DB cart does not exist then create new one.

BUILD

Load existing cart from the database along with any products it contains and add cart hooks.

METHODS

add

Add one or more products to the cart.

Possible arguments:

  • single product sku (scalar value)

  • hashref with keys 'sku' and 'quantity' (quantity is optional and defaults to 1)

  • an array reference of either of the above

In list context returns an array of Interchange6::Cart::Products and in scalar context returns an array reference of the same.

clear

Removes all products from the cart.

load_saved_products

Pulls old cart items into current cart - used after user login.

remove

Remove single product from the cart. Takes SKU of product to identify the product.

rename

Rename this cart. This is the writer method for "name" in Interchange6::Cart.

Arguments: new name

Returns: cart object

set_sessions_id

Writer method for "sessions_id" in Interchange6::Cart.

set_users_id

Writer method for "users_id" in Interchange6::Cart.

update

Update quantity of products in the cart.

Parameters are pairs of SKUs and quantities, e.g.

  $cart->update(9780977920174 => 5,
                9780596004927 => 3);

Triggers before_cart_update and after_cart_update hooks.

A quantity of zero is equivalent to removing this product, so in this case the remove hooks will be invoked instead of the update hooks.

Returns updated products that are still in the cart. Products removed via quantity 0 or products for which quantity has not changed will not be returned.

HOOKS

The following hooks are available:

before_cart_add_validate

Executed in "add" before arguments are validated as being valid. Hook receives the following arguments:

Receives: $cart, \%args

The args are those that were passed to add.

        my ( $cart, $args ) = @_;
        foreach my $arg ( @$args ) {
            my $sku = ref($arg) eq 'HASH' ? $arg->{sku} : $arg;
            die "bad product" if $sku eq "bad sku";
        }
    }
before_cart_add

Receives: $cart, \@products
