DataBind Wijmo Grid to Zoom Data


Provide real-time Zoom data to interactive controls.

The Connect Server enables you to use Web services to connect to and query Zoom data. This article details how to import an OData feed of Zoom data into Wijmo Grid.

Configuring Connect Server

To work with live Zoom data in Wijmo Grid, we need to connect to Zoom from Connect Server, provide user access to the new virtual database, and create OData endpoints for the Zoom data.

Add a Connect Server User

Create a User to connect to Zoom from Wijmo Grid through Connect Server.

  1. Click Users -> Add
  2. Configure a User
  3. Click Save Changes and make note of the Authtoken for the new user

Connect to Zoom from Connect Server

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Open Connect Server and click Connections
  2. Select "Zoom" from Available Data Sources
  3. Enter the necessary authentication properties to connect to Zoom.

    Start by setting the Profile connection property to the location of the Zoom Profile on disk (e.g. C:\profiles\Zoom.apip). Next, set the ProfileSettings connection property to the connection string for Zoom (see below).

    Zoom API Profile Settings

    To authenticate to Zoom, you can use the OAuth standard to connect to your own data or to allow other users to connect to their data.

    First you will need to create an OAuth app. To do so, navigate to https://marketplace.zoom.us/develop/create and click Create under the OAuth section. Select whether or not the app will be for individual users or for the entire account, and uncheck the box to publish the app. Give the app a name and click Create. You will then be given your Client Secret and Client ID

    After setting the following connection properties, you are ready to connect:

    • AuthScheme: Set this to OAuth.
    • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
    • OAuthClientID: Set this to the OAuth Client ID that is specified in your app settings.
    • OAuthClientSecret: Set this to the OAuth Client Secret that is specified in your app settings.
    • CallbackURL: Set this to the Redirect URI you specified in your app settings.
  4. Click Save Changes
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions (SELECT is all that is required for Reveal).

Add Zoom OData Endpoints in Connect Server

After connecting to Zoom, create OData Endpoints for the desired table(s).

  1. Click OData -> Tables -> Add Tables
  2. Select the Zoom database
  3. Select the table(s) you wish to work with and click Next
  4. (Optional) Edit the resource to select specific fields and more
  5. Save the settings

(Optional) Configure Cross-Origin Resource Sharing (CORS)

When accessing and connecting to multiple domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in OData -> Settings.

  • Enable cross-origin resource sharing (CORS): ON
  • Allow all domains without '*': ON
  • Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
  • Access-Control-Allow-Headers: Authorization

Save the changes to the settings.

Connect to Zoom Data using Wijmo Grid

Create a Real-Time Grid

Follow the steps below to consume Zoom data from the Wijmo JavaScript controls:

  1. Load the required Wijmo, jQuery, and Knockout libraries: 
    			
			<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
			<script src="http://code.jquery.com/ui/1.11.0/jquery-ui.min.js"></script>

			<!--Theme-->
			<link href="http://cdn.wijmo.com/themes/aristo/jquery-wijmo.css" rel="stylesheet" type="text/css">

				<!--Wijmo Widgets CSS-->
				<link href="http://cdn.wijmo.com/jquery.wijmo-pro.all.3.20161.90.min.css" rel="stylesheet" type="text/css">

					<!--Wijmo Widgets JavaScript-->
					<script src="http://cdn.wijmo.com/jquery.wijmo-open.all.3.20161.90.min.js"></script>
					<script src="http://cdn.wijmo.com/jquery.wijmo-pro.all.3.20161.90.min.js"></script>
					<script src="http://cdn.wijmo.com/interop/wijmo.data.ajax.3.20161.90.js"></script>

					<!--Knockout JS Library-->
					<!-- Both of the links below can work -->
					<script src="http://cdn.wijmo.com/wijmo/external/knockout-2.2.0.js"></script>
					<!--<script src="http://cdn.wijmo.com/amd-js/3.20161.90/knockout-3.1.0.js"></script>-->

					<!--Wijmo Knockout Integration Library-->
					<script src="http://cdn.wijmo.com/interop/knockout.wijmo.3.20161.90.js"></script>
  2. Create a ViewModel and connect to it using the ODataView. You will need to replace the placeholder values for the URL of the API Server, an API Server user, and the authtoken for that user. 
    			
			<script id="scriptInit">
			$.support.cors = true;
			var viewModel;

			function ViewModel() {
			var meetingregistrantsView = new wijmo.data.ODataView("http://MyServer:MyPort/api.rsc/MeetingRegistrants", {
			ajax: {
			dataType: "jsonp",
			username: "MyUser",
			password: "MyAuthtoken",
			data: { "$inlinecount": null }
			},
			pageSize: 10
			});
			meetingregistrantsView.refresh();
			meetingregistrantsView.nextPage();
			this.meetingregistrants = meetingregistrantsView;
			this.prevPage = function () {meetingregistrantsView.prevPage();};
			this.nextPage = function () {meetingregistrantsView.nextPage();};
			}

			$(document).ready(function () {
			viewModel = new ViewModel();
			ko.applyBindings(viewModel, $(".container").get(0));
			});
			</script>
  3. DataBind: Below is a simple table with some paging buttons, which you can paste into the body section of your markup. 
    			
			<h2>Connect to Live Zoom Data in Real Time</h2>

			<h3>MeetingRegistrants</h3>
			<div>
				<button title="previous page" class="pagebuttons" data-bind="click: prevPage, button: {}">
					<span class="ui-icon ui-icon-seek-prev" />
				</button>
				<button title="next page" class="pagebuttons" data-bind="click: nextPage, button: {}">
					<span class="ui-icon ui-icon-seek-next" />
				</button>
			</div>
			<table id="demo-grid" data-bind="wijgrid: { 
      data: meetingregistrants, 
      showFilter: true, 
      allowPaging: true,
      pagerSettings: { position: 'none'},
      columnsAutogenerationMode: 'append',
    }" >
			</table>

At this point, you may be prompted to re-enter the username and authtoken. After doing so, a resulting table or grid should appear, as seen below. You can filter and sort through pages of Zoom data.
