Saving a Portal Item Back to ArcGIS Online

BillGrow — Tue, 12 Nov 2013 19:37:10 GMT

Is there a method in the javascript api to save a portal item back to ArcGIS Online after making changes in a custom application? For example adjusting a webmap's initial extent.

Thanks,
~Bill

This functionality isn't available in the javascript api. In order to update ArcGIS Online content you'll need to use the ArcGIS Portal Rest API:

Hi Kelly,

I don't see a REST operation that can be used to update the item data. Can you point out which operation is for editing and updating the item data?

Thanks,

Jason

Thanks Kelly,

I'm just getting back to this issue, so I'll give it a try. Jason, I'm assuming by looking at the page provided, updates can be made using a PUT request http://livedocs.dojotoolkit.org/dojo/request/xhr

Instead of using dojo/request/xhr take a look at esri.request. It is a utility method that simplifies the process. More info on using esri.request can be found here:

Jason,

Please take a look at the code snippet.

function updateWebMap() {
        var portal = new esri.arcgis.Portal("http://www.arcgis.com/sharing/rest");
        portal.signIn().then(getItem);
      };
function getItem(user) {
        var itemUrl = user.portal.url + "/content/items/" + webMapId;
        var request = esri.request({
          url: itemUrl,
          content: {
            "f": "json"
          }
        });
        request.then(dojo.partial(getWebMapText, user, itemUrl));
      };
function getWebMapText(user, itemUrl, item) {
        if (item.type === "Web Map") {
          //get current webmap text
          var request = esri.request({
            url: itemUrl + "/data",
            content: {
              "f": "json"
            }
          });
          request.then(dojo.partial(updateWebMapText, item, user));
        } else {
          alert("Not a Webmap item!");
        }
      };
function updateWebMapText(item, user) {
        var folder = (item.ownerFolder) ? "/" + item.ownerFolder : "";
        var userItemUrl = user.userContentUrl + folder + "/items/" + item.id;
        var webMapText = dojo.toJson(webMapJson);//your updated web map

        var contentUpdate = {
          "text": webMapText,
          "f": "json"
        };
        var request = esri.request({
          url: userItemUrl + "/update",
          content: contentUpdate
        }, {
          usePost: true
        });
        request.then(requestSucceeded);
        //console.log(userItemUrl);
      };
