How to get a watch list in widget in Service Portal ?

Hi Team,

How to get watch list for a particular ticket opened in service portal.

How to create a widget for this?

Any suggestions or ideas will help me a lot.

Thanks.

Hi Nithin,

Here is a quick widget I made, however it does not have any save functionality so you would have to add that. Also the sn-record-picker does not allow to add an email address as the usual watch list field does. If your goal is only to display a read of what was set on creation than this would do the job by simply setting sn-disabled="true".

HTML:

<div ng-if="data.canRead" class="panel panel-primary b">

   <div class="panel-heading">

       <h4 class="panel-title pull-left">

           ${Watch list}

       </h4>

       <div class="clearfix"></div>

   </div>

   <div class="panel-body">

           <div class="text-center text-italic text-muted">

               <sn-record-picker field="watch_list" sn-disabled="!data.canWrite" table="'sys_user'" display-field="'name'" search-fields="'name'" value-field="'sys_id'" default-query="'active=true'" multiple="true"></sn-record-picker>

           </div>

   </div>

</div>

Client script:

function($scope, spUtil) {

       var c = this;

       

       $scope.watch_list = {   

               displayValue: c.data.displayValue,   

               value: c.data.value,

               name: 'watch_list'   

   }; 

}

Server script:

(function() {

       

       var table = $sp.getParameter('table')

       var sys_id = $sp.getParameter('sys_id')

       var gr = new GlideRecord(table);

       if(gr.get(sys_id)){

               data.canRead = gr.watch_list.canRead();

               data.canWrite = gr.watch_list.canWrite();

               if(data.canRead){

                       data.displayValue = gr.getDisplayValue('watch_list');

                       data.value = gr.getValue('watch_list');

               }

       }

})();

I know this is incomplete but I hope it helps.

That only gives you the ability to provide a Watch List at time of ticket entry.

The widget is supposed to allow the ability to change it after submission.

In the ticket fields widget you are going to have to user sn-record-picker. To make it available to edit after the ticket is created:

HTML Template:

<sn-record-picker field="watch_list" sn-disabled="!data.canWrite" table="'sys_user'" display-field="'name'" search-fields="'name'" value-field="'sys_id'" default-query="'active=true^{web_service_access_only=false}user_nameISNOTEMPTY'" multiple="true">

$

…

Client Script:

$scope.watch_list = ;

$scope.save = function(){

c.data.action = 'change_req_wl';

c.data.watchList = $scope.watch_list.value;

c.server.update().then(function(){

});

};

Server Script:

if(input && input.action=='change_req_wl'){

if(gr.watch_list != input.watchList || (gr.caller_id != input.req && input.req.length>0)){

if (gr.watch_list != input.watchList){

gr.watch_list = input.watchList; gr.update(); gs.addInfoMessage('Updated');

}

else{

gs.addErrorMessage("Update failed, you don't have the required access");

}

….

data.canWrite = gr.watch_list.canWrite();

…..

var dV = gr.getDisplayValue('watch_list');

var sV = gr.getValue('watch_list');

data.displayValue = dV == '' ? [] : dV;

data.value = sV == null ? [] : sV;

Can you give screen shots of each? I feel like I'm missing something here.

Hi Laurent,

I am getting bunch of errors while loading this widget. Did you came across any issues for this?

Also is there a way we can add email address to watchlist using this widget?
