angularjs app structure/ $scope - angularjs

I can't seem to wire this up properly. I'll list the appropriate pieces. My issue is accessing the injected resources. All of the dependent pieces are undefined when I try to reference them.
var app = angular.module('app', ['ngResource','ui.bootstrap', 'ngGrid','app.services', 'app.directives', 'app.controllers'
])
.config(['$routeProvider', function ($routeProvider) {
return $routeProvider.
when('/', { templateUrl: 'partials/transaction.view.html', controller: 'TransactionCtrl' }).
when('/about', { templateUrl: 'partials/about.view.html', controller: 'AboutCtrl' }).
when('/transaction', { templateUrl: 'partials/transaction.view.html', controller: 'TransactionCtrl' }).
otherwise({ redirectTo: '/' });
}])
.config(['$httpProvider', function ($httpProvider) {
return $httpProvider.responseInterceptors.push(['logger', '$rootScope', '$q',
function (logger, $rootScope, $q) {
var error, success;
success = function (response) {
$rootScope.$broadcast("success:" + response.status, response);
logger.log("success:" + response.status);
return response;
};
error = function (response) {
var deferred;
deferred = $q.defer();
$rootScope.$broadcast("error:" + response.status, response);
logger.log("error:" + response.status);
return $q.reject(response);
};
return function (promise) {
return promise.then(success, error);
};
}
]);
}])
.run(['$rootScope', 'logger', function ($rootScope, logger) {
return $rootScope.$on('$routeChangeSuccess', function (event, currentRoute, priorRoute) {
return $rootScope.$broadcast("" + currentRoute.controller + "$routeChangeSuccess", currentRoute, priorRoute);
});
}]);
...the controllers are here:
angular.module('pennyWatch.controllers', ['$scope', '$location','logger', 'ngGrid', 'transactionService']).
controller('TransactionCtrl', [function ($scope, logger, ngGrid, transactionService) {
//code here
}]).
controller('AboutCtrl',[function ($scope, logger) {
$scope.logEntries = logger.logEntries;
}]);
So none of the resources I specified are available (all undefined): '$scope', '$location','logger', 'ngGrid', 'transactionService'
Any light shed on this would be greatly appreciated!
Thanks

I'm pretty sure the syntax for a controller is:
.controller('TransactionCtrl', ['$scope', 'logger', 'ngGrid', 'transactionService', function ($scope, logger, ngGrid, transactionService) {
//code here
}]);
You first list what to inject, then as the last element of the array to define a function with parameters that will represent what's injected.
For instance you could even have:
.controller('TransactionCtrl', ['$scope', 'logger', 'ngGrid', 'transactionService', function ($s, logr, ngGrid, transServ) {
//code here
}]);
This is to allow for easy minification.
The alternative controller syntax uses the parameter names when choosing what to inject. And since minification usually involves shortening variable names, it's suggested you use the syntax above.
Alternative syntax:
.controller('TransactionCtrl', function ($scope, logger, ngGrid, transactionService) {
//code here
});

I think you are swapping module-loading with service-injection
when declaring the pennywatch.controllers module, you should invoke the angular.module function passing the module dependencies in brackets, not the services. many of the services you cannot access are in the ng module, for instance
service injection is applied at the controller level

services throwing error in the controller as function not defined

amcApp.service('utilService', function ($http, $q,$rootScope) {
var getSupportTypes = function () {
var deferred = $q.defer();
$http.get($rootScope.BaseUrl+'vendor/supportTypes')
.then(function daoSuccess(response) {
console.log("Getting Sub Customer Service call success ", response);
deferred.resolve(response);
}, function daoError(reason) {
console.log("Getting SubC data service call error", reason);
deferred.reject(reason);
});
return deferred.promise;
};
return{
getSupportTypes : getSupportTypes,
};
});
Above is the service I defined.
Below is the controller I defined.
amcApp.controller('contractForm', ['$scope', '$http','$rootScope','$filter', '$uibModal', '$state', 'testService','utilService','contractService',
function ($scope, $http,$rootScope, $filter,$uibModal, testService,utilService,contractService) {
//Service of getting the Support Types.
utilService.getSupportTypes().then(function(response){
$scope.supportTypes = response.data.UtilDataType;
});
}]);
This is the error I'm getting:
Can I get any suggestions?
Check the dependencies what you inject into the controller, you have an extra $state in the array which has not been passed to the function. I would suggest to remove as the following:
amcApp.controller('contractForm', ['$scope', '$http', '$rootScope', '$filter', '$uibModal', 'testService','utilService','contractService',
function ($scope, $http, $rootScope, $filter, $uibModal, testService, utilService, contractService) {
//Service of getting the Support Types.
utilService.getSupportTypes().then(function (response){
$scope.supportTypes = response.data.UtilDataType;
});
}]);
On the other hand I would simply remove all the not used services, I assume this is working also fine:
amcApp.controller('contractForm', ['$scope', 'utilService', function ($scope, utilService) {
//Service of getting the Support Types.
utilService.getSupportTypes().then(function (response) {
$scope.supportTypes = response.data.UtilDataType;
});
}]);
Just a suggestion - if you keep your code clean it is much easier to figure out the root cause of any issues.

Restangular ignores setBaseUrl

The app runs on http://domain1 an must request data from http://domain2 with the following code:
'use strict';
// Declare app level module which depends on views, and components
var myApp = angular.module('myApp', [
'ngRoute',
'restangular'
]);
myApp.config(['$routeProvider', 'RestangularProvider', function($routeProvider, RestangularProvider) {
$routeProvider.when('/view1', {
templateUrl: '/view1.html',
controller: 'View1Ctrl'
});
$routeProvider.otherwise({redirectTo: '/view1'});
RestangularProvider.setBaseUrl("http://domain2/");
}]);
var rest = null;
myApp.controller('View1Ctrl', ['$scope', 'Restangular', function($scope, Restangular) {
rest = Restangular;
var cursos = Restangular.one("resource",100).get()
}]);
Nonetheless, the request goes to http://domain1. What is going on? I also inspected the Restangular configuration, by putting Restangular in the global scope, as the rest variable, and the base url seems is property set.
Hey you can create a factory and use different domain to get data something like below
(function () {
'use strict';
angular.module('app')
.factory('Domain2Restangular', ['Restangular', Domain2RestangularFunction]);
function Domain2RestangularFunction( Restangular) {
return Restangular.withConfig(function(RestangularConfigurer) {
var baseURL = 'http://domain2';
RestangularConfigurer.setBaseUrl(baseURL);
RestangularConfigurer.setDefaultHeaders({'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8' });
});
}
}());
You can invoke
return Domain2Restangular.all('')
.post(data)
.then(function(response) {
return response;
}, function(error) {
return error
});

Inject dependency to controller called by directive

I would like to know if it is possible (if it is, so how? :)), to inject a dependency to a controller called by a directive.
I have a controller controller called MyCtrl. Here is his signature:
app.controller('MyCtrl', function ($scope, dataService, aDependency){...}
This Controller is usually defined in my route:
.segment('myPage', {
templateUrl: templatesUrl + 'mypage.html',
resolve: {
aDependency: ['$q', 'dataService', '$location', function ($q, dataService, $location) {
var defer = $q.defer();
dataService.retrieveCCData(defer, $location);
return defer.promise;
}],
},
controller: 'MyCtrl'
})
But now, I would also like to call this controller from a directive.
Problem is that I don't know How to inject the aDependency.
It said that the provider is unknown.
Here's my directive:
app.directive('gettingStarted1', ['dataService', function (dataService) {
return {
restrict: 'E',
templateUrl: templatesUrl + 'mypage.html',
controller: 'MyCtrl',
//resolve: {
//datasources: ['dataService', function (dataService) {
//return null;
//}]
//}
};
}]);
Resolve is impossible in directive.
Some help will be appreciate
Thank you
Make aDependency a separate service.
app.provider('aDependency', function () {
this.$get = ['$q', 'dataService', '$location', function ($q, dataService, $location) {
var defer = $q.defer();
dataService.retrieveCCData(defer, $location);
return defer.promise;
}];
});
You can resolve it with
resolve: {
'aDependency': 'aDependency',
}
or
resolve: ['aDependency'];
you could use the controller Function from the directive
.directive("sampledirective", function (dependancy1, dependancy2, ....) {
return {
scope: '=',
controller: function ($rootScope, $scope) {
//DO your controller magic here where you got your scope stuff
}
}
})
One thing i learned it seems the $scope values arent immediatly updated from directive to Controller. If you use objects like
$scope.smth.smth = 'test'
It gets updated immediatly else you would need to $apply

AngularJS - Consuming REST API with Restangular in a factory

I understand how to use Restangular in a controller, however my thoughts are that Restangular is essentially an ORM on steroids.
The ORM shouldn't have any knowledge of the state of the application. That is the job of the controller.
I also want to re-use queries to the ORM, and as such, I believe that Restangular should be used inside a service.
My problem is that I am a js / angularjs and restangular noob, having only about 2-3 months exp with anything front-end.
My Controllers:
app.controller('AdminSupplierIndexController',
['$scope', '$stateParams', '$state', 'Supplier',
function ($scope, $stateParams, $state, Supplier) {
$state.reload();
Supplier.getAll.then(function (suppliers) {
$scope.suppliers = suppliers;
});
}]);
app.controller('AdminSupplierDetailController',
['$scope', '$stateParams', 'Supplier',
function ($scope, $stateParams, Supplier) {
Supplier.getOne({ supplierId : $stateParams.supplierID}).then(function(supplier) {
$scope.supplier = supplier;
});
}]);
My Factory
app.factory('Supplier', ['Restangular', function (Restangular) {
return {
getAll: Restangular.all('supplier').getList(),
getOne: Restangular.one('supplier', supplierId).get()
};
}]);
My Supplier.getAll method works fine - I can list all the suppliers from the Supplier factory.
My problem is with my Supplier.getOne method.
Question 1: How do I inject the supplierId into the factory? I am getting ReferenceError: supplierId is not defined
Question 2: Am I trying to over-engineer things considering that I would have to create individual methods for C-R-U-D for every single factory when these methods are already provided by Restangular?
I know this is old, but an alternate way would just be to wrap it within a function. This way, you can keep any other logic within the service/method.
app.factory('Supplier', ['Restangular', function (Restangular) {
return {
getAll: Restangular.all('supplier').getList(),
getOne: function(supplierId) {
return Restangular.one('supplier', supplierId).get()
}
};
}]);
Found the solution in https://github.com/mgonto/restangular#decoupled-restangular-service
Essentially, the way I have solved this problem is as follows:
app.js
$stateProvider
...
.state('admin.supplier', {
url : "/supplier",
templateUrl : 'templates/admin/supplier/index.html',
controller: "AdminSupplierIndexController",
resolve: {
suppliers: ['Supplier', function(Supplier) {
return Supplier.getList();
}]
}
})
.state('admin.supplier.detail', {
url : "/:supplierId",
templateUrl : "templates/admin/supplier/detail.html",
controller: "AdminSupplierDetailController",
resolve: {
supplier : ['Supplier', '$stateParams', function(Supplier, $stateParams) {
return Supplier.one($stateParams.supplierId).get();
}]
}
})
...
Supplier.js
app.factory('Supplier', ['Restangular', function(Restangular) {
return Restangular.service('supplier');
}]);
SupplierControllers.js
app.controller('AdminSupplierIndexController', ['$scope', '$stateParams', '$state', 'suppliers',
function ($scope, $stateParams, $state, suppliers) {
$state.reload();
$scope.suppliers = suppliers;
}]);
app.controller('AdminSupplierDetailController', ['$scope', 'supplier',
function ($scope, supplier) {
$scope.supplier = supplier;
}]);

Angular routeProvider Resolve not called

I have a simple resolve function set up in my route provider. Something like
.config(['$routeProvider', 'Constants', function config($routeProvider, Constants) {
$routeProvider.
when('mypage', {
templateUrl: 'partials/mypage.tpl.html',
controller: 'MyPageCtrl',
reloadOnSearch: false,
resolve: {
factory: 'MyPageResolve'
}
})
)];
Where that factory is declared in a module like this:
.factory('MyPageResolve', ['$q', '$log', 'someAPI',
function ($q, $log, someAPI) {
var defer = $q.defer();
var postUserFunc = function () {
someAPI.get(
function(data, status) { //$http.get().success() func
defer.resolve();
}
);
};
return defer.promise;
}]);
What's happening is on straight refresh or on the first load, this resolve method is hit. However, if I have a $location.url('/mypage'); change from one route to this one, angular is not re-resolving this controller.
I might be not thinking of resolve in the right way, and if so, would take recommendations on the 'angular' way to do this. I would like all this information loaded before the view, and is variable based on the route params.
Ends up I needed to make that factory into just a function. A factory acts as a singleton, so it will only run once.
So I made my factory look like:
var myPageResolve = ['$q', '$log', 'someAPI',
function ($q, $log, someAPI) {
var defer = $q.defer();
var postUserFunc = function () {
someAPI.get(
function(data, status) { //$http.get().success() func
defer.resolve();
}
);
};
return defer.promise;
}]);
And instead of resolving on 'myPageResolve', I resolved on myPageResolve. Very subtle change made all the difference.
