DataBind Wijmo Grid to Drift Data


Provide real-time Drift data to interactive controls.

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

Configuring Connect Server

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

Add a Connect Server User

Create a User to connect to Drift 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 Drift 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 "Drift" from Available Data Sources
  3. Enter the necessary authentication properties to connect to Drift.

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

    Drift API Profile Settings

    Drift uses OAuth-based authentication.

    You must first register an application here: https://dev.drift.com. Your app will be assigned a client ID and a client secret. Set these in your connection string via the OAuthClientId and OAuthClientSecret properties. More information on setting up an OAuth application can be found at https://devdocs.drift.com/docs/.

    After setting the following options in the ProfileSettings connection property, you are ready to connect:

    • AuthScheme: Set this to OAuth.
    • OAuthClientId: Set this to the Client Id that is specified in your app settings.
    • OAuthClientSecret: Set this to Client Secret that is specified in your app settings.
    • CallbackURL: Set this to the Redirect URI you specified in your app settings.
    • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
  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 Drift OData Endpoints in Connect Server

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

  1. Click OData -> Tables -> Add Tables
  2. Select the Drift 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 Drift Data using Wijmo Grid

Create a Real-Time Grid

Follow the steps below to consume Drift 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 contactsView = new wijmo.data.ODataView("http://MyServer:MyPort/api.rsc/Contacts", {
			ajax: {
			dataType: "jsonp",
			username: "MyUser",
			password: "MyAuthtoken",
			data: { "$inlinecount": null }
			},
			pageSize: 10
			});
			contactsView.refresh();
			contactsView.nextPage();
			this.contacts = contactsView;
			this.prevPage = function () {contactsView.prevPage();};
			this.nextPage = function () {contactsView.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 Drift Data in Real Time</h2>

			<h3>Contacts</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: contacts, 
      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 Drift data.
