Build MVC Applications with Connectivity to PingOne Data

In this article, we will guide you through the process of utilizing wizards within Visual Studio to seamlessly integrate the CData ADO.NET Provider for PingOne into a basic MVC (Model, View, Controller) project.

Create the Entity Framework Model

Follow the steps below to save connection properties and map tables to entities in the data model.

1. Create a new MVC project in Visual Studio. In this example, the project name is MvcPingOneApp.

2. If you are using Entity Framework 6, you will need to take the preliminary step of registering the PingOne Entity Framework provider for your project. See the "LINQ and Entity Framework" chapter in the help documentation for a guide.

   Note that MVC 3 scaffolding and MVC 4 scaffolding do not support Entity Framework 6. You can use your scaffolding with Entity Framework 6 by upgrading to the latest version of MVC.
3. To add the .edmx file from the designer, right-click your Models folder and click Add New Item. Select ADO.NET Entity Data Model, name the model, and click Add. In this example, the name of the model is PingOneModel.
4. In the Entity Data Model wizard, select the option 'EF Designer from database'. The Entity Data Model wizard is displayed.
5. Click New Connection. Select CData PingOne Data Source in the dialog that is displayed.

6. Specify the required connection string properties.

   To connect to PingOne, configure these properties:

   • : The region where the data for your PingOne organization is being hosted.
   • : The type of authentication to use when connecting to PingOne.
   • Either (required when using the default PingOne domain) or , configured as described below.

   Configuring WorkerAppEnvironmentId

   is the ID of the PingOne environment in which your Worker application resides. This parameter is used only when the environment is using the default PingOne domain (auth.pingone). It is configured after you have created the custom OAuth application you will use to authenticate to PingOne, as described in Creating a Custom OAuth Application in the Help documentation.

   First, find the value for this property:

   1. From the home page of your PingOne organization, move to the navigation sidebar and click Environments.
   2. Find the environment in which you have created your custom OAuth/Worker application (usually Administrators), and click Manage Environment. The environment's home page displays.
   3. In the environment's home page navigation sidebar, click Applications.
   4. Find your OAuth or Worker application details in the list.
   5. Copy the value in the Environment ID field. It should look similar to:
      

      WorkerAppEnvironmentId='11e96fc7-aa4d-4a60-8196-9acf91424eca'

   Now set to the value of the Environment ID field.

   Configuring AuthorizationServerURL

   is the base URL of the PingOne authorization server for the environment where your application is located. This property is only used when you have set up a custom domain for the environment, as described in the PingOne platform API documentation. See Custom Domains.

   Authenticating to PingOne with OAuth

   PingOne supports both OAuth and OAuthClient authentication. In addition to performing the configuration steps described above, there are two more steps to complete to support OAuth or OAuthCliet authentication:

   • Create and configure a custom OAuth application, as described in Creating a Custom OAuth Application in the Help documentation.
   • To ensure that the driver can access the entities in Data Model, confirm that you have configured the correct roles for the admin user/worker application you will be using, as described in Administrator Roles in the Help documentation.
   • Set the appropriate properties for the authscheme and authflow of your choice, as described in the following subsections.

   OAuth (Authorization Code grant)

   Set to OAuth.

   Get and Refresh the OAuth Access Token

   After setting the following, you are ready to connect:

   • : GETANDREFRESH. To avoid the need to repeat the OAuth exchange and manually setting the each time you connect, use .
   • : The Client ID you obtained when you created your custom OAuth application.
   • : The Client Secret you obtained when you created your custom OAuth application.
   • : The redirect URI you defined when you registered your custom OAuth application. For example: https://localhost:3333

   When you connect, the driver opens PingOne's OAuth endpoint in your default browser. Log in and grant permissions to the application. The driver then completes the OAuth process:

   1. The driver obtains an access token from PingOne and uses it to request data.
   2. The OAuth values are saved in the location specified in , to be persisted across connections.

   The driver refreshes the access token automatically when it expires.

   For other OAuth methods, including Web Applications, Headless Machines, or Client Credentials Grant, refer to the Help documentation.

   A typical connection string is below:

   AuthScheme=OAuth;WorkerAppEnvironmentId=eebc33a8-xxxx-4f3a-yyyy-d3e5262fd49e;Region=NA;OAuthClientId=client_id;OAuthClientSecret=client_secret;InitiateOAuth=GETANDREFRESH;

   👁 The connection for the model. (QuickBooks is shown.)
   

7. Name the connection and select whether to include sensitive information, such as connection credentials, in the connection string. For simplicity, this example saves sensitive information in Web.config. The connection settings are saved as PingOneEntities.

   👁 The completed connection step in the ADO.NET Entity Data Model wizard. (A QuickBooks connection is shown.)
   
8. Select the views you need. In this example, [CData].[Administrators].Users is imported. Also, the option to pluralize object names is deselected in this example. Click Finish to create the .edmx file.👁 Tables to be imported into the .edmx file. (QuickBooks is shown.)
   
9. Build your project to complete this step.

Scaffold the Controller and Views

Once you've established the model and completed the project build, you can employ ASP.NET Scaffolding wizards to generate both the controller and the views.

1. In Solution Explorer, right-click the controllers folder and click Add -> Controller. Select MVC 5 Controller with views, using Entity Framework.
2. In the Add Controller dialog that is then displayed, select the following options:
   • Model class: Select a table you imported; for example, [CData].[Administrators].Users.
   • Data context class: Select your context class.
3. Leave the default values for the other fields. 👁 Creating a new controller from an existing entity data model in the Add Controller dialog in MVC 5. (QuickBooks is shown.)
   

You can now access the list of [CData].[Administrators].Users records at http://MySite/[CData].[Administrators].Users. With every state change the site picks up any data changes. 👁 The live table. (QuickBooks is shown.)
