How to inject service to angular constant

Question

I would like to define a constant which use $locale service. Constants are objects, so I can't inject it as parameter as in case of controller. How can I use it?

angular.module('app').constant('SOME_CONSTANT', {
  'LOCALE': $locale.id.slice(0, 2)
})

Answer 1

You can manually grab $locale with the $injector. Observe the following...

app.constant('SOME_CONSTANT', { 
    'LOCALE': angular.injector(['ng']).get('$locale').id.slice(0, 2) 
});
