How can I use the Grails Asset plugin to reference a static HTML file?

Currently, I am working with Grails 2.4.1 and have incorporated version 1.9.7 of the Grails Asset Pipeline Plugin.

In my project, there is a javascript file that defines an AngularJS directive. This Javascript file needs to access a static HTML template file which will be used by the AngularJS directive.

The question at hand is how do I correctly reference the HTML file within the asset directory?

Project Structure:

  • grails-app
  • assets
    • javascripts
      • directives
        • hierarchyviewer.js
        • hierarchyviewer.html

Project Structure when using the Angular Template Asset pipeline grails plugin

  • grails-app
    • assets
      • javascripts
        • directives
          • hierarchyviewer.js
      • templates
        • hierarchyviewer.tpl.html

The file 'directivea.js' contains the following code:

angular.module('HierarchyViewer', []).directive('hierarchyviewer',function(){
    return {
        restrict: 'EA',
        scope: {},
        replace: true,
        controller: function ($scope, $http) {
        },
        templateUrl: 'hierarchyviewer.tpl.html'
    }

})

However, upon attempting to load a page that references the directive, a 404 error is returned for the directives/directivea.html reference.

How should I properly reference the template while utilizing the Asset Pipeline plugin?

Answer №1

Hello there, I am the creator of the Angular Template Asset Pipeline Plugin and I have some suggestions for you to make it work smoothly.

  • Ensure that module names are written in camel case format for the plugin to function correctly.
  • The plugin removes the .tpl extension from file names, resulting in a file named hierarchyviewertemplate.js in this scenario.
  • It is crucial to keep file names (excluding extensions) unique to avoid conflicts.

Regarding file locations, having files with identical names in different parent folders within the assets directory can cause issues. For example:

  • /assets/javascripts/hierarchyviewertemplate.js
  • /assets/templates/hierarchyviewertemplate.tpl.html

For code implementation, consider using the following structure:

//= require_self
//= require_tree /hierarchyViewer

angular.module('hierarchyViewer', []).directive('hierarchyviewer',function(){
    return {
        restrict: 'EA',
        scope: {},
        replace: true,
        controller: function ($scope, $http) {
        },
        templateUrl: 'hierarchyviewertemplate.html'
    }
});

This setup assumes your hierarchyviewertemplate.tpl.html file is located at:

grails-app -> assets -> templates -> heirarchyViewer -> hierarchyviewertemplate.tpl.html

If your template resides within a plugin, replace require_tree with require_full_tree.

I hope these suggestions are helpful for you.

Have you heard about the awesome plugin known as angular-template-asset-pipeline? What it does is clever - it stores your .tpl.htm templates in the $templateCache. This makes it super easy to use them in your Angular application. Take a look at this code snippet for an example (taken from the documentation):

angular.module('myApp.appSection', ['ngRoute'])
.config(function($routeProvider) {
      $routeProvider
          .when('/home', {
              templateUrl: 'home.htm'
          })
          .otherwise({redirectTo: '/home'});
});
