Implementing View Files for Custom Content Types in NetSuite

TL;DR Opening

This article explains how to implement view files for custom content types (CCT) in NetSuite, detailing the critical steps required to define functionality and dependencies essential for your custom applications.

What is a View File?

A view file in NetSuite defines what the Custom Content Type (CCT) loads when it is added to the application. It outlines the dependencies, initializes settings, and connects HTML templates for rendering dynamic content.

How to Implement a View File

To effectively implement a view file, follow these steps:

1. Review Dependencies

The view requires CustomContentType.Base.View, which extends Backbone.View. This base class initializes CCT settings. An example dependency configuration could be as follows:

1"text-purple-400">define('NetSuite.ImageViewer.ImageViewerCCT.View'
2,  [
3    'CustomContentType.Base.View'
4  ,  'Utils'
5  ,  'netsuite_imageviewer_imageviewercct.tpl'
6  ,  'jQuery'
7  ]
8,  "text-purple-400">function (
9    CustomContentTypeBaseView
10  ,  Utils
11  ,  netsuite_imageviewer_imageviewercct_tpl
12  ,  jQuery
13  )

2. Define the Template

Specify the template to include the necessary HTML for rendering data:

template: netsuite_imageviewer_imageviewercct_tpl

For more information about templates, refer to the relevant section on Implementing the Template File.

3. Initialize the View

Define the initialize() function to instantiate the view with provided options:

1initialize: "text-purple-400">function initialize(options) {
2  "text-purple-400">if (options) {
3    "text-purple-400">this.container = options.container;
4  }
5  "text-purple-400">this._initialize();
6}

4. Install Function

Implement an install() function, which includes processing AJAX requests if necessary:

install: "text-purple-400">function(settings, context_data) {
  "text-purple-400">this._install(settings, context_data);
  "text-purple-400">var promise = jQuery.Deferred();
  "text-purple-400">return promise.resolve();
}

Note: Settings cannot be edited until the promise resolves.

5. Define contextDataRequest

Specify required access to data via contextData objects. For instance, the ImageViewer CCT may need access to item data:

contextDataRequest: ['item']

6. Validate Context Data

Override validateContextDataRequest to confirm data existence:

validateContextDataRequest: "text-purple-400">function validateContextDataRequest() {
  "text-purple-400">return true;
}

7. Define getContext()

This method provides data to the template. Define fields in a settings object, leveraging CCT records:

getContext: "text-purple-400">function getContext() {
  // context logic here
}

Fields defined might include:

8. Save the View File

Complete the coding and save your view file, ensuring all dependencies and methods are correctly implemented.

9. Next Steps

To continue creating an extension for a CCT, refer to the Implement the Template File section for further guidance.

Who This Affects

• Developers: Responsible for customizing and deploying CCT extensions.
• System Administrators: Setup and managing CCTs through Site Management Tools (SMT).

Key Takeaways

• View files define CCT behavior and must specify dependencies and templates.
• Initializing views and handling context data are critical for dynamic content.
• Validation and context management ensure data integrity within the application.
