Aikau: How to call a repo webscript from an aikau widget

francesco_forna

##Dear All,

I need to add a new button on Share Search result page that allow users to export search metadata results as Excel file.

So, I made the repo webscript to make the Excel outputstream based on user search data (i.e: terms, query, etc..) and I'm looking to bind to the Share Aikau Search Result page.

I added to Share search page a new button linke this:

var searchResultsMenuBar  = widgetUtils.findObject(model.jsonModel, "id", "SEARCH_RESULTS_MENU_BAR");
searchResultsMenuBar.config.widgets.push({
    id: "EXPORT_BUTTON_SEARCH",
    name: "alfresco/buttons/AlfButton",
    config: {         
      additionalCssClasses:"call-to-action",label : "export.search.result"
   }
})

Now how can we add the repo webscript call? Pheraps adding something like this:
        publishPayloadType: 'PROCESS',
        useHash: true,
        hashDataMapping: {
            searchTerm: "widgetsContent.0.config.searchTerm",
            siteId: "widgetsContent.0.config.siteId",
            searchSort: "widgetsContent.0.config.searchSort"
        },
        publishPayload: {

        }Could you suggest me any sample to do this?

Thank you.

Ok Guys,

we've found the solutions. I report some basic steps to solve this mess J.

1) Write your JS backend widget service and register it to the Aikau runtime; for example a servce to make XHR repository calls:

define(["dojo/_base/declare",
        "alfresco/services/BaseService",
        "alfresco/core/CoreXhr",
        "service/constants/Default",
        "alfresco/core/PathUtils",
        "alfresco/enums/urlTypes",
        "dojo/_base/lang",
        "dojo/_base/array",
        "alfresco/util/hashUtils"],
    function(declare, BaseService, CoreXhr, AlfConstants, PathUtils, urlTypes, lang, array, hashUtils) {

        return declare([BaseService, CoreXhr, PathUtils], {

            constructor: function alfresco_services_BaseService__constructor(args) {
                this.alfSubscribe("EXPORT_SEARCH_RESULTS_SERVICE", lang.hitch(this, this.onAction));
            },
            onAction: function facetedsearch_DocumentService_onAction(payload) {
                
               //  hashUtils.getHash() - IT CONTAINS YOUR SEARCH PARAMETERS
               // query - scope - searchTerm
                console.log(hashUtils.getHash());
                
                this.serviceXhr({
                    url: AlfConstants.PROXY_URI + "/api/YOUR_WEBSCRIPT_AND_SEARCH_PARAMS",
                    method: "GET",
                    successCallback: this.onSuccess,
                    callbackScope: this
                });

            },
            onSuccess: function facetedsearch_DocumentService_onSuccess(response, originalRequestConfig) {

                Alfresco.util.PopupManager.displayMessage({ title: this.message("export.search.result"), text: this.message("export.search.result.ok")});
            },
            onFailure: function facetedsearch_DocumentService_onFailure(response, originalRequestConfig) {

                Alfresco.util.PopupManager.displayMessage({ title: this.message("export.search.result"), text: this.message("export.search.result.no")});
            }
        })
    }
);

2) Declare your new faceted-search widgets override, for example by adding a new button:

//PUT THE NEW SERVICE IN PREVIOUS MODEL SERVICE LIST
model.jsonModel.services.push("widgets/medica-search-export");

//ADD YOUR BUTTON AND CALL THE NEW SERVICE BY USING the publishTopic config element.
var searchResultsMenuBar  = widgetUtils.findObject(model.jsonModel, "id", "SEARCH_RESULTS_MENU_BAR");
searchResultsMenuBar.config.widgets.push({
    id: "EXPORT_BUTTON_SEARCH",
    name: "alfresco/buttons/AlfButton",
    config: {
        label : "medica.export.search.result",
        additionalCssClasses:"call-to-action",
        publishPayloadType: 'PROCESS',
        publishTopic: "EXPORT_SEARCH_RESULTS_SERVICE"
    }
});
