Question

Angular.js loads, processes, and presents a dynamic template that is fetched through an $resource from a REST

My Angular application requires customizable reporting functionality. The goal is to permit users to select from a variety of available reports, with a backend REST API providing both the template and data in JSON format for user customization.

The app will then need to insert the template into a "reporting" view page and populate it with the provided data using Angular's compilation process for display.

Although I've explored using ng-include, it only supports URLs or file paths, which are not suitable for my needs as the template text is retrieved dynamically via the REST service. If ng-include could accept template text directly, that could potentially solve the issue, but unfortunately it does not.

I attempted to create a directive to handle this task, calling a method (getTemplate()) to load the fetched template from the scope. However, it seems my directive does not have access to the necessary scope for this operation.

What approach should I take to achieve this functionality? While a directive seems like the best solution, I am struggling to implement it correctly, feeling overwhelmed by the documentation and numerous failed attempts.

Answer №1

To render the dynamic template on the DOM, you can compile it within a controller like this:

var element = angular.element('#myselector');   
element.html(dynamicHtml);

$compile(element.contents())($scope);

It's recommended to organize your route templates by using a single DIV container and pulling all static templates into a JavaScript file with tools like HTMLToJS or grunt task:

<section class="view">
  <div id="myselector"></div>
</section>

I attempted to create a directive in order to call a method on the page (getTemplate()) that would load the template already fetched from the scope. However, my directive lacks access to the scope.

It is true that direct access to the scope may be limited, but there is a workaround for passing data from the scope to the directive. For instance, if you wish to pass a variable "x" from the scope to the directive, you can utilize the following syntax:

<directive directiveVar='x'/>

Within the directive, it is necessary to implement an isolated scope like this:

"scope": {
    "directiveVar": "="
},

This variable will only be accessible in the controller and postlink function, therefore your directive's template should appear as follows:

<ng-bind-html="directiveVar"/>

In the postlink phase, you may require the following code snippet:

$scope.directiveVar = $sce.trustAsHtml($scope.directiveVar)
