Lists

In this document

Lists

A list is a collection resource that returns ordered links to other resources.

Cortex lists follow this format:

  • An element link for each resource in the list.

  • A type set to elasticpath.collections.links. This type indicates there are no properties associated with the list, only links to other resources.

Lists Example: lineitems

lineitems are a list resource that contain links to each lineitem in the shopper's cart. In the lineitems resource, each lineitem is represented as an element link with a type set to elasticpath.collections.links: 
  1. {
  2.   "self": {
  3.     "type": "elasticpath.collections.links",
  4.     "uri": "/commerce-legacy/carts/mobee/guz=/lineitems",
  5.     "href": "http://api.elasticpath.net/cortex/carts/mobee/guz=/lineitems"
  6.   },
  7.   "links": [
  8.     {
  9.       "rel": "element",
  10.       "rev": "list",
  11.       "type": "elasticpath.carts.line-item",
  12.       "uri": "/commerce-legacy/carts/mobee/guz=/lineitems/hfq=",
  13.       "href": "http://api.elasticpath.net/cortex/carts/mobee/guz=/lineitems/hfq="
  14.     },
  15.     {

Pagination

Lists can be paginated when large numbers of links return.

Cortex paginated lists follow this format:
  • An element link for each resource on a page.
  • A next link to retrieve the next page of links.
  • A previous link to retrieve the previous page of links.
  • A type set to elasticpath.collections.pagination, which indicates the list is paginated.
  • A pagination object with the following fields:
    • current: The current page number.
    • page-size: The number of links on each page, excluding the next/previous pagination links.
    • pages: The total number of pages.
    • results: The total number of links, excluding the next/previous pagination links.
    • results-on-page: The number of links on the current page, excluding the next/previous pagination links.

Lists Pagination Example: Item Keyword Search

An item keyword search returns a paginated list resource that links to each item found by the keyword search:
  1. {
  2.   "self": {
  3.     "type": "elasticpath.collections.pagination",
  4.     "uri": "/commerce-legacy/searches/mobee/keywords/items/m43g=/pages/2",
  5.     "href": "http://api.elasticpath.net/cortex/searches/mobee/keywords/items/m43g=/pages/2"
  6.   },
  7.   "pagination": {
  8.     "current": 2,
  9.     "page-size": 5,
  10.     "pages": 6,
  11.     "results": 29,
  12.     "results-on-page": 5
  13.   },
  14.   "links": [
  15.     {
