The Ultimate Guide to Initializing Variables in UI Router State Access

In my application, I have defined 2 states. One is "tickets" which matches /tickets ...

$stateProvider // defines the states of my application
  .state("tickets", { // assigns properties to each state
      url: "/tickets", // route
      templateUrl: "modules/tickets/views/ticketsTemplate.html", // template to use
      controller: "TicketsController", // controller to use
      controllerAs : "tickets" // alias for the controller, for using this
  });

and the other one is "tickets.buscar" which matches /tickets/:id and uses the same controller as the parent ("TicketsController") ...

.state("tickets.buscar",{
      url: "/:id",
      templateUrl: "modules/tickets/views/ticketsResult.html"
      }
  ) // inherits the controller from the parent

In the controller, there is an init() function that initializes the necessary variables.

this.init = function(){
  this.title = "Tickets";
  this.id = $state.params.id;

  if(this.id){
    this.getTicket(this.id);
  };
};

this.init();

Based on my understanding from the UI Router documentation, there are 3 ways to access a state:

  • by using the URL (or following an external link)
  • using $state.go()
  • using ui-sref in the HTML

I am trying to find a way to trigger a controller reload so that regardless of how the state is accessed, the init function is executed.

I know about the { reload : true } option in $state.go() but that only addresses one of the access methods. I also looked into this other question, but the solution provided doesn't work, and the $state parameter isn't documented in UI Router's documentation.

Answer №1

An effective method could involve utilizing the resolve object during state creation to automatically set the ticket for you. While untested, this approach should prove successful.

.state("tickets.buscar", {
    url: "/:id",
    templateUrl: "modules/tickets/views/ticketsResult.html",
    resolve: {
        ticket: function($state) {
            // return the output of `getTicket`
            // consider relocating the entire method here
        }
    }
}

Subsequently, within your controller, remember to inject both ticket and $scope.

angular.module('someModule')
.controller('TicketsController', ['$scope', 'ticket', function($scope, ticket) {
    console.log(ticket);
]);

Answer №2

One great option would be to utilize the `StateChangeSuccess´ event:

$rootScope.$on('$stateChangeSuccess', 
function(event, toState, toParams, fromState, fromParams){ 
    //start setting up everything here...
})
