Ability to copy/duplicate an order (with and without association)

[NikRimington]

It would be great if there was an easy way to "snapshot/copy/dupliate" an order with or without an association to the original.

Scenario.

Building a Wishlist mechanism where users of the site can save their basket to a wishlist (they can have multiple wishlists), where a wishlist is a snapshot of the basket at that point in time. When creating the snapshot you wouldn't want to associate it with the origin, but you might want to "load your snapshot" back into the basket, where in this case you'd want to keep the wishlist intact but duplicate it and create a relationship between it. This would allow you to see orders that originated from a wishlist.

So we've had a bit of a private chat an so far we've come up withe a couple of possible options

Option 1 - CreateFrom factory method

Look at introducing a new Order factory method CreateFrom where you can pass an existing order and potentially some create options to create a new order from an existing order

Order.CreateFrom(existingOrder, CreateFromOptions.Lines & CreateFromOptions.Shipping & CreateFromOptions.Billing)

Pros

• Can create a new order from existing in one line of code

Cons

• Can only "create" from one order so if you need to merge multiple wishlist's, it can't be done this way

Option 2 - CopyFrom instance method

Look at adding either a series of CopyFrom methods such as CopyOrderLinesFrom, CopyCustomerInfoFrom, etc methods, or maybe a single CopyFrom method with similar config options as per the CreateFrom example to control what is copied

Order.Create(uow, storeId, language, currency, taxClass, orderStatus)
    .CopyFrom(existingOrder, CopyFromOptions.OrderLines & CopyFromOptions.Customer)

Pros

• Can merge multiple orders into one order

Cons

• You'd have to first create the new order first and then call the copy from method

[NikRimington]

Why not allow the following

Order.CopyFrom(existingOrder, CopyFromOptions.OrderLines & CopyFromOptions.Customer)
         .CopyLinesFrom(anotherExistingOrder, CopyLiesFromOptions.AppendAndUpdate)

Where AppendAndUpdate means if the same product exists it merges the quantities together, if it does it adds it.
Other options there could be AppendAndIgnore, where existing lines aren't updated with combined quantities if the product already exists on the order.

I would have thought, though, that if you wanted to merge multiple orders, the only thing you'd want to merge would be the OrderLines?

Basically the more I think about the more I would imagine you'd have a "base order" to copy from, but then you want to include the lines from another. I can imagine you'd want to include other stuff?
