Executing Requests with the Client API

All apps created with Code On Time app generator contain a single client-side API used for all server-side operations, including Select, Insert, Update, Delete, Report, Batch Edit, etc. One significant advantage of using a centralized API is that any style of user interface is able to access the same API – this has allowed the co-development of Classic and Touch UI.

Another major advantage in the client-side API is that developers are able to extend their apps with custom behavior utilizing the same data access routines – any access control rules, data controller customizations, and security restrictions will also equally apply to these custom requests.

To access the client API from custom JavaScript, simply call the method $app.execute(options) with the required parameters set on the options object. See a list of available options parameters below.

Property Description Default Value
controller The controller to direct the request to. (required)
view The view of the controller to use. grid1
done
success
Callback function when the request was send and received successfully. First argument contains the results. List of records can be found under the result property equal to the name of the controller.
fail
error
Callback function when the request failed.
command The name of the command to execute. “Select”
argument The argument of the command to execute.
lastCommand The last command name.
lastCommandArgument The last command argument.
pageSize The number of records to return in a single page. 100
pageIndex The page number to return. 0
filter An array of field filter objects. Each object must have 3 properties:
- “field” specifies the field name
- “operation” specifies the filter operation to perform
- “value” specifies the value of the filter. For operations with two operands (such as “between”), specify an array of two values.
values An array of field value objects. Each object can have the following properties:
- “name” specifies the name of the field matching the one defined in the controller.
- “value” specifies the current value of the field.
- “newValue” specifies the new value.
- “modified” specifies that the new value will be used in any Insert or Update expressions. Setting “newValue” will set “modified” to true by default.
selectedValues An array of strings that contain the primary keys of the selected records. Used for batch update.
tags Specify a list of tags that can be processed on the server.
requiresData Specifies if data should be returned to the client. true
requiresAggregates Specifies if aggregates defined on the view should be returned with the request. false
fieldFilter Specifies a list of fields to include in the response for each record. Not setting this value will return all fields.
format Specifies if field values should be formatted when the results are returned. true
includeRawResponse Specifies if the result should include the raw response in the rawResponse property. false

The simplest way to test your queries is to use the Developer Tools Console, available in most modern browsers.

First, browse to your running site in your favorite browser. Press “F12” to bring up Developer Tools. Switch to the Console tab.

Using the Console tab of Developer Tools to test the $app.execute() API.

You may now begin typing in $app.execute() requests in the console. Note the use of console.log(result), which will print the JavaScript object to the console when the request returns.

The following examples will use the online Northwind sample.

Select

The simplest use case for using the API is to request a page of data. See the following example below on how to fetch the first 10 records from the Orders table where the field “ShipCountry” is equal to “USA”.

$app.execute({
    controller: 'Orders',
    pageSize: 10,
    filter: [
        { field: 'ShipCountry', operator: '=', value: 'USA' }
    ],
    done: function (result) {
        console.log(result);
    }
})

The result shown in the Developer Tools Console.

Selecting 10 orders with a filter.

Insert

In order to insert records to a particular table, the request must specify the “Insert” command and a list of field values. This list is represented by the values property. Each field value object contains a field name. Values that will be assigned to the new record are stored in the field value’s newValue property. The primary key of the table is added as a field value object with the property value equal to null in order for the response to return the new primary key of the inserted record.

$app.execute({
    controller: 'Orders',
    command: 'Insert',
    values: [
        { name: 'OrderID', value: null },
        { name: 'ShipCity', newValue: 'San Diego' },
        { name: 'ShipCountry', newValue: 'USA' }
    ],
    done: function (result) {
        console.log(result);
    }
})

See the results below.

Inserting a record using the $app.execute() API.

Refreshing the view in the browser window will reveal the new record.

The new record is displayed in the grid.

Update

When performing operations on an existing record, either the primary key or an array of selected values must be specified. New field values must be specified in the newValue property.

$app.execute({
    controller: 'Orders',
    command: 'Update',
    values: [
        { name: 'OrderID', value: 11083 },
        { name: 'OrderDate', newValue: new Date() }
    ],
    done: function (result) {
        console.log(result);
    }
})

The result is shown below.

Updating an order via the $app.execute() API.

The result can be seen by refreshing the list of orders.

The updated field value is visible by refreshing the page.

Delete

Delete operations must specify the primary key in the values array.

$app.execute({
    controller: 'Orders',
    command: 'Delete',
    values: [
        { name: 'OrderID', value: 11079 }
    ],
    done: function (result) {
        console.log(result);
    }
})

See result below.

Deleting a record.

The rowsAffected property will be equal to “1” if the record was successfully deleted.

Announcing Cloud On Time Connector for DotNetNuke

Starting with release 8.6.6.0, apps created with any edition of Code On Time generator can be integrated with external DotNetNuke websites with the help of Cloud On Time Connector for DotNetNuke.

Cloud On Time Connector for DotNetNuke is a ready-to-deploy module that provides OAuth 2.0 endpoints for any number of external apps created with Code On Time. It also enables application data presentation/links within the portal pages. Utilize the power of Code On Time to rapidly build database applications integrated with DotNetNuke.

Users will also have the ability to “Login with DotNetNuke”, and use their existing DotNetNuke accounts in the Code On Time app.

The instructions below will use the Northwind sample and a fresh instance of DNN 9.0.2 hosted on Microsoft Azure.

Make sure to enable Content Management System for the database of your app. 

Installing Cloud On Time Connector for DotNetNuke module

The next step is to install the Cloud On Time Connector for DotNetNuke module into your DNN portal instance. Download the latest release of the module from the Releases page.

Using your preferred browser, navigate to your DNN portal and sign in with a SuperUser account.

Logging into DotNetNuke with a SuperUser  account.

The module is now installed in your DotNetNuke instance.  Note that the website will restart, which may cause some delay immediately after installation.

Configuring Authentication Endpoint

Cloud On Time Connector for DotNetNuke can integrate any number of external applications into your DotNetNuke portal. An endpoint page with an instance of the module will need to be created in the portal for each integrated application. The developer must configure the Code On Time app and the module instance on the portal page with matching parameters to enable communications over OAuth 2.0 protocol.

First, let’s create a publicly-accessible endpoint page.  Under the “Content” icon in the sidebar, select the “Pages” option.

Opening the Pages panel.

In the top right corner of the Pages panel, press “Add Page”.

Adding a new page.

Specify the following properties:

Property Value
Name end-point-app1
URL /end-point-app1
Display In Menu Off

The name and URL provided above are for demonstration purposes only. You can choose any name and URL that you like.

Under the Permissions tab, check the box to allow all users to view tab. This will enable both anonymous and authenticated users to access the page.

Allowing all users to view the tab.

Press “Add Page”. On the next screen, drag the page to the end of the page list.

Positiong the page in the menu.

The browser will then redirect to the page in edit mode. In the bottom-left corner, press the “Add Module” button.

Adding a module to the page.

From the Add Module screen, click on “Cloud On Time Connector”.

Adding the "Cloud On Time Connector" module.

Drag the floating module and drop on the first dashed placeholder in the end-point-app1 page.

Dropping the module into the first placeholder.

Mouse over the top right corner of the module instance on the page to reveal the control bar.  Mouse over the gear icon, and press “Settings” in the hover menu.

Opening the settings for the module.

Switch to the “Configuration” tab. Use the following settings:

Property Value Explanation
Mode Authentication Endpoint This module instance will serve to authenticate users and offer an endpoint for the Code On Time app.
Client ID app1 The unique identifier for your Code On Time app.
App URL [Your app URL] The location that your application is accessible from.
example: https://cotapp1.azurewebsites.net
Client Secret [randomly generated] A secret value used for server-to-server communications.
example: 4eba319ad0fe41c9b1f02ae69b7466f2
Allowed Tokens Portal:PortalName User:DisplayName A comma- or space-separated list of DNN tokens that will be passed to the app created with Code On Time at the time of user login. Optional.

When configuration is complete, press “Update” to save your changes. Now the module instance on the page end-point-app1 has been configured to accept authentication connections.

We will need to configure the app created with Code On Time to request authentication connections to the DotNetNuke portal.

Navigate to your app, login as admin, and switch to the Site Content page. Press the Plus icon to create a new record.

Adding a new Site Content record.

Select “Open Authentication Registration”, and press OK.

Creating a new Open Authentication Registration.

Configure the following:

Property Value
Authentication DotNetNuke
Client Id app1
Client Secret [randomly generated secret from the module settings]
Client Uri [Your DNN portal URL]/end-point-app1
Redirect Uri [Public URL of your app]/appservices/saas/dnn
Tokens Portal:PortalName User:DisplayName

Your configuration should look like the one below:

Open Authentication registration form has been filled out.

Press the checkmark icon to save the new record. Your app is now configured for authentication connections with DotNetNuke portal.

To test the connection, log out of your app.

Logging out of the app.

Once logged out, your app will show the login form. Notice that a new action “LOGIN WITH DOTNETNUKE” is now available.

Login with DotNetNuke is now visible on the login form.

Push the new action, and you will be navigated to your DotNetNuke portal. If you are not signed into your portal, the login page will be displayed.

Redirected to the DNN login page.

After user has logged in, the login page will redirect to the authentication endpoint. If there are no issues with the configuration, the portal and app will communicate over OAuth2.0 protocol. A user account will be created in the app membership database with the DotNetNuke username, email, roles, picture, and random password. If tokens were requested in the configuration of the app, then the values will be captured by the application.

The DotNetNuke user has been signed in.

If the Account Manager is enabled in the application, subsequent logins will not authenticate with DotNetNuke portal again until the user logs out. You can add “Auto Login: true” parameter to the sys/saas/dnn entry in the SiteContent table to automatically redirect unauthenticated users to DotNetNuke.

If you have developed multiple applications, then create additional authentication endpoint pages following the instructions above for each app. Note that your apps can be deployed anywhere and do not need to physically reside on the same server as the DotNetNuke portal.

Data Presentation in DNN Portal

The Cloud On Time Connector for DotNetNuke module also allows displaying data from your application directly in the portal pages.

Navigate to your DotNetNuke portal with the configured application endpoint as a SuperUser account.

Hover over the Content icon on the sidebar, and press “Pages”.

Allowing registered users to access the tab.

Press “Add Page”. On the next screen, drag to place the new page after the Home page.

Positioning the Products page.

You will be navigated to the new Products page. In the bottom left corner, press “Add Module”.

Adding a module to the page.

Select the “Cloud On Time Connector” module from the list.

Adding the Cloud On Time Connector module.

Drag the floating module and drop on the first dashed area in the page.

Dropping the module onto the page.

Hover over the gear icon above the module, and press “Settings”.

Opening the settings for the module.

Switch to the Configuration tab. If the authentication endpoint has already been configured, then the Mode property of this module instance will be set to “Data Presentation”. Enter the following:

Property Value
Mode Data Presentation
App App1 ([your URL])
Page URL ~/pages/products
Height 600px
Show Navigation false

Press “Update” to save your changes. Proceed to refresh the page. The module will now display a grid of products.

A grid of products is now displayed within the DotNetNuke portal

Accessing User Tokens

If tokens were configured for both sys/saas/dnn entry and the authentication endpoint of DotNetNuke portal, then the values can be used in the implementation of business rules in the application. For example, token “User:DisplayName” can be accessed by the following sample code:

SQL:

set @Result_ShowAlert = 'Hello ' + @Profile_User_DisplayName

C#:

Result.ShowAlert("Hello " + Convert.ToString(GetProperty("Profile_User_DisplayName")));

Visual Basic:

Result.ShowAlert("Hello " & Convert.ToString(GetProperty("Profile_User_DisplayName")))
