Angular [$injector:unpr] Unknown provider with customize directive - angularjs

Question

I have a little issue by using a customize directive within the template field of UI-Bootstrap modal directive.
My aim is send data to modal via resolve attribute and re-use these resolved parameters inside the controller of my own directive.
var app = angular.module('app', ['ui.bootstrap']);
app.controller('MyCtrl', ['$scope', '$modal', function($scope, $modal) {
$scope.openModal = function () {
var popup = $modal.open({
template: '<my-modal></my-modal>',
resolve : {
mydata : function() {
return 42;
}
}
});
};
}]);
app.controller('ModalController', ['$scope', 'mydata', function($scope, mydata) {
//The error is in this directive controller
$scope.mydata = mydata;
}]);
app.directive('myModal', function() {
return {
restrict: 'E',
templateUrl : 'mymodal.html',
controller : 'ModalController',
replace: true
};
});
Maybe I proceed in the wrong way.
Any suggest to make this code functionnal ?

Answer 1

The resolve parameters are only injected to the controller defined in the $modal.open config parameters, but you want to inject it to the directive controller. That will not work. Imagine you would use the myModal directive somewhere else, there wouldn't be a myData object that could be used.
But i don't realy see, what you need the directive for. You could go much easier this way:
app.controller('MyCtrl', ['$scope', '$modal',
function($scope, $modal) {
$scope.openModal = function() {
var popup = $modal.open({
templateUrl: 'mymodal.html',
controller: 'ModalController',
resolve: {
mydata: function() {
return 42;
}
}
});
};
}
]);
// Here the mydata of your resolves will be injected!
app.controller('ModalController', ['$scope', 'mydata',
function($scope, mydata) {
$scope.mydata = mydata
}
]);

you need to provide an Object "mydata". Ensure, that you have a correct implemented factory which provides your myData Object. If you had done that, you can "inject" your myData Object where ever you want to.
yourApp.MyDataFactory = function () {
var myData = {i: "am", an: "object"};
return myData;
}
this would provide an "myData" Object

I'm not sure what you are trying to accomplish with the directive, but if you are trying to provide a generic way to invoke the $model, that you can then use from many places in your app, you may be better off to wrap $model with a service. Than you can then call from other places in your app.
I forked and modified your plunkr to work this way: http://plnkr.co/edit/0CShbYNNWNC9SiuLDVw3?p=preview
app.controller('MyCtrl', ['$scope', 'modalSvc', function($scope, modalSvc) {
var mydata = {
value1: 42
};
$scope.openModal = function () {
modalSvc.open(mydata);
};
}]);
app.factory('modalSvc', ['$modal', function ($modal) {
var open = function (mydata) {
var modalInstance,
modalConfig = {
controller: 'ModalController',
resolve: {
mydata: function () {
return mydata;
}
},
templateUrl: 'mymodal.html'
};
modalInstance = $modal.open(modalConfig);
return modalInstance;
};
return {
open: open
};
}]);
Also, I changed mydata to be an object, rather than '42', as I am sure you will have other data to pass in. the markup was updated accouringly:
<div class="modal-body">
BODY {{mydata.value1}}
</div>
Doing it this way, the resolve property works, and you can get your data.
As for the other answers mentioning you must define mydata, the resolve property passed into $model does this for you, so it can be injected into the modal's controller (ModalController), like you have done.
