Class Method Details

.find_applicable_sops(options = {}) ⇒ Object

@return array of hashes, each with the following structure: it basically returns the stage_index as well as the sop_index alongwith their respective ids. the matches array contains the product ids to which that sop is applicable, out of the product ids supplied.

this has to return the cart_items_latest_time, as well as requirement_query_hash both are hashes. we should just update the results of the query on the step itself. and schedule order should return the last step. and nothing more. secondly, there is only one call. basically it sends the cart_item information to the step so schedule order should receive the cart items array. and nothing else.

#schedule_order_new(cart_items, cart_item_to_preceeding_step_hash) ⇒ Object

@param cart_items : array of cart item objects, basically the cart_items from the order which are applicable to this sop. @param cart_item => last_step hash. this hash contains the last step for each cart item if more than one cart item has been updated in a step, so suppose we have more than one cart item on a particular step, then what ? step_address => [cart_item_ids,step] step_address => [cart_item_ids,step]

Returns:

  • nil: returns nothing.
