AngularJS: Issue with directive function not being executed

I created a directive in my code, but for some reason the function I provided to define the directive is not being called. It was working perfectly fine before, and now it just suddenly stopped without any clear explanation.

Below is the code snippet of my directive:

portalApp.directive('contactPanel', function () {
    console.log("NEVER SHOWN!");
    return {
        restrict: 'AE',
        replace: 'true',
        templateUrl: 'partials/account/contactPanel.html',
        scope: {
            contact: '=contact',
            primaryRoleName: '@',
            roleName: '@',
            primary: '=primary',
            locations: '=locations'
        },
        controller: function (userService, $rootScope, $scope) {
            ...snip...
        }
    };
});

Here is an example of how I use this directive:

<contact-panel contact="user.account.contacts.billing" role-name="billing"
               locations="locations"></contact-panel>

Please note that I am using the correct casing, camel-case in JavaScript, and hyphenation in HTML tags.

The issue lies in the fact that the message 'NEVER SHOWN!' from the second line of the directive declaration does not appear in the console when I check. While other console messages show up, it seems like the framework is just ignoring my directive declaration completely.

I am seeking a solution for this problem and would appreciate any insights or debugging methods to help resolve these issues.

Answer №1

There are two potential reasons why you are seeing the behavior described. One possibility is that the HTML with the directive was not compiled, while the other is that the directive is not properly registered.

In the case where it was "not compiled," this could happen if the directive is being used outside of the Angular app. For example:

<div ng-app="portalApp">
 ...
</div>
...
<contact-panel></contact-panel>

Alternatively, if you dynamically added the HTML but did not $compile and link it.

On the other hand, in the scenario where it was "not registered," it may be due to re-registration of the app's module. This can occur like so:

var portalApp = angular.module("portalApp", []);
portalApp.directive("contactPanel", function(){...});

// then elsewhere you use a setter:

angular.module("portalApp", []).controller("FooCtrl", function(){});    
// instead of using the getter:
// var app = angular.module("portalApp");

The second call to angular.module("portalApp", []) actually removes the previous registration of .directive("contactPanel", ....

Answer №2

After some investigation, I finally identified the root cause of the issue. It turns out that inadvertently moving the directive into a configuration block was the main culprit:

portalApp.config(function ($stateProvider, $urlRouterProvider) {
    portalApp.directive('contactPanel', function () {
        console.log("NEVER SHOWN!");
        return {
            ...snip...
        };
    });
});

Once I relocated it outside of the configuration block and into the global scope, the directive immediately displayed correctly.

The reason behind this behavior is that Angular processes directives before configuration code like so:

runInvokeQueue(moduleFn._invokeQueue);    // runs directives
runInvokeQueue(moduleFn._configBlocks);   // runs config blocks

This means that any additions to the _invokeQueue (which the directive() function performs) within a config block will not be executed.

I appreciate the assistance from everyone who attempted to troubleshoot this with me.
