Setting a variable in the App.Config using Angular Translate

In my Angular App, I have installed Angular Translate.

Here is a snippet of my app.js file:

.config(function($stateProvider, $urlRouterProvider, $ionicConfigProvider, $ionicFilterBarConfigProvider, $httpProvider, $translateProvider) {

    $translateProvider.translations('it', {       
        SEARCH: 'Cerca',
    })

    $translateProvider.translations('en', {       
        SEARCH: 'Search',
    })

    //... Various .state(...

});

//Translate config
$translateProvider.preferredLanguage('en');

$ionicFilterBarConfigProvider.placeholder("Search");

My goal is to dynamically change the placeholder text for the search bar based on the selected translation.

I attempted this approach without success:

var SRC_WORD = $filter('translate')('SEARCH');
$ionicFilterBarConfigProvider.placeholder(SRC_WORD)

It didn't work as expected.

I also tried this method, but since it's not within the HTML context, it did not work either:

$ionicFilterBarConfigProvider.placeholder("{{'SEARCH' | translate }}")

Seems like I'm missing something. Any ideas?

Answer №1

During the configuration phase, service providers like $ionicFilterBarConfigProvider can be accessed, while service instances like $ionicFilterBarConfig are only available during the run phase.

The reason for this distinction is that the config phase (within the config block) is where service instances are set up before being created.

In certain scenarios, it is feasible to treat a service provider as an instance and configure it dynamically during the run phase:

app.config(function ($provide, $ionicFilterBarConfigProvider) {
  $provide.value('$ionicFilterBarConfigProvider', $ionicFilterBarConfigProvider);
});

app.controller(..., function ($filter, $ionicFilterBarConfigProvider) {
  var SRC_WORD = $filter('translate')('SEARCH');
  $ionicFilterBarConfigProvider.placeholder(SRC_WORD)
});

This approach does not come with any guarantees and its effectiveness relies on the internal workings of the specific service.
