How to pass a XID from an input container to a query

---

Hey All,
I'm having a bit of trouble getting a <ma-point-query> directive to work with a data source XID from a <md-input-container>.
As you can see, when I manually enter the XID the code works as expected, but how do I automatically use the XID of the selected Data Source?

<md-input-container>
        <label>Choose a data source</label>
        <ma-data-source-list ng-model="myDataSource"></ma-data-source-list>
    </md-input-container>
    {{myDataSource.name}}   {{myDataSource.xid}}   {{myDataSource.id}}
    <ma-point-query query="'eq(dataSourceXid,{{myDataSource}})&amp;sort(deviceName,name)&amp;limit(200)'" points="eventPoints"></ma-point-query>
{{eventPoints.name}}

<md-input-container>
       <label>Choose a data source</label>
       <ma-data-source-list ng-model="myDataSource"></ma-data-source-list>
   </md-input-container>
   {{myDataSource.name}}   {{myDataSource.xid}}   {{myDataSource.id}}
   <ma-point-query query="'eq(dataSourceXid,DS_f4bd539a-6d8d-4557-8248-1650c7a447e9)&amp;sort(deviceName,name)&amp;limit(200)'" points="eventPoints"></ma-point-query>
   {{eventPoints}}

Sorry I sent the wrong snippet, its meant to say {{myDataSource.xid}} in the query not {{myDataSource}}

@zenvakil said in How to pass a XID from an input container to a query:

<ma-point-query query="'eq(dataSourceXid,DS_f4bd539a-6d8d-4557-8248-1650c7a447e9)&sort(deviceName,name)&limit(200)'" points="eventPoints"></ma-point-query>

    <ma-point-query query="'eq(dataSourceXid,'+myDataSource.xid+')&sort(deviceName,name)&limit(200)'" points="eventPoints"></ma-point-query>

   

That's how I do it
