Reusing of functions which is defined between controllers

i would like to reuse the code defined between the controllers
.controller('GenericController', ['$scope', '$controller', '$rootScope', '$dialogs', '$state', '$http', '$modal', '$q', '$timeout', 'projectFactory', 'projectPromise', 'phaseFactory', 'buFactory', 'stakeholderGroupFactory', 'ldapFactory', 'genericFactory', 'User',
function ($scope, $controller, $rootScope, $dialogs, $state, $http, $modal, $q, $timeout, projectFactory, projectPromise, phaseFactory, buFactory, stakeholderGroupFactory, ldapFactory, genericFactory, User) {
$scope.testing = function() {
console.log("Hello");
};
}]);

You can use the factory and create the object for the function to reuse it.
app.factory("sample",function(){
return function() {
console.log("Hello");
};
})
else collating multiple common functions
app.factory("commonFunctions",function(){
commonFunction1(){
console.log("common func1")
}
commonFunction2(){
console.log("common func2")
}
return {
commonFunction1: commonFunction1,
commonFunction1: commonFunction2
};
})

Used the $controller for the importing this fixed my issue

AngularJS $injector:unpr issue with Angular Bootstrap modal

So i'm getting a Error: [$injector:unpr] when I try and inject $modal into my controller.
here is what I have:
var controllers = angular.module("controllers", ['services', 'ngCookies','ngStorage','ui.bootstrap', 'ngRoute']);
controllers.controller("MainController", ['$scope', '$http', '$location', 'configurationData', 'dashboardData', 'orderByFilter', '$cookieStore' , 'isstevenFilterArray', '$rootScope', '$modal' , function ($scope, $http, $location, configurationData, dashboardData, orderByFilter, $cookieStore, isstevenFilterArray, $rootScope, $modal)
<script src="vendor/angular-bootstrap/ui-bootstrap-tpls.js"></script>

You have to put <script src="vendor/angular-bootstrap/ui-bootstrap-tpls.js"> line at the top. After that only you should be creating module and controllers.
Try below code:
<script src="vendor/angular-bootstrap/ui-bootstrap-tpls.js"></script>
var controllers = angular.module("controllers", ['services', 'ngCookies','ngStorage','ui.bootstrap', 'ngRoute']);
controllers.controller("MainController", ['$scope', '$http', '$location', 'configurationData', 'dashboardData', 'orderByFilter', '$cookieStore' , 'isstevenFilterArray', '$rootScope', '$modal' , function ($scope, $http, $location, configurationData, dashboardData, orderByFilter, $cookieStore, isstevenFilterArray, $rootScope, $modal)

AngularJS constants undefined is not an object

new to Angular and I'm trying to inject constants from a separate file. It seems to work with the DI, but when I try to use it, I get an error: Error: undefined is not an object (evaluating 'CApiEndpoints.authUrl').
I tried dot notation and brackets as suggested in Accessing AngularJS constants but continue to get the error.
The files are included in index.html, and DI doesn't complain.
index.html
<script type="text/javascript" src="js/angular/constants.js"></script>
<script type="text/javascript" src="js/angular/app.js"></script>
js/angular/constants.js
var app = angular.module('appConst', []);
app.constant('CApiEndpoints', {
authUrl: 'http://api.example.com/v1/',
...
});
and my js/angular/app.js
var app = angular.module('app', ['ngRoute', 'ngCookies', 'appConst', 'appServices']);
app.controller('pageController', ['$scope', '$route', '$http', '$cookies', 'CApiEndpoints', function($scope, $route, $http, $cookies, $routeParams, $location, CApiEndpoints){
console.log(CApiEndpoints); // shows 'undefined'
$http({
method : 'GET',
url : CApiEndpoints.authUrl + 'user_info'
})
.then(
function successCallback(response) {
console.log(response);
},
function errorCallback(response) {
console.log(response);
});
}]);
Any help would be appreciated. I've searched for the last 2 hours trying to figure this out.

While injecting dependencies inside your controller function using DI inline array annotation, they must follow the order how they are injected in array.
If you follow above rule you will come to know that you have two extra paramters inside your function, so you should remove those two unwanted ($routeParams, $location) dependency.
app.controller('pageController', ['$scope', '$route', '$http', '$cookies', 'CApiEndpoints',
function($scope, $route, $http, $cookies, CApiEndpoints){
//controller code
}
]);
If you haven't added those parameter mistakenly, you should add those parameter on both side inside function & array.
app.controller('pageController', ['$scope', '$route', '$http', '$cookies', '$routeParams', '$location', 'CApiEndpoints',
function($scope, $route, $http, $cookies, $routeParams, $location CApiEndpoints){
//controller code
}
]);

Using Angular services to hold commonly required data

I am currently writing my first application in Angular and have been very much enjoying all the framework has to offer so far. Like most newbies I set off building everything into a main controller, copying the tutorials. I am now seeing the error of my ways and refactoring.
My question is about services holding data that is commonly required among controllers.
I've now taken the data out of the 'main controller' and placed it into a service that I have injected into both controllers requiring access. Now though neither controller sees the functionality I've defined in the new service:
varianceService is not defined
Being new to this approach i welcome all and any help, aswell as help with my current problem, any comments on the best way to apply this approach would also be highly appreciated.
Thanks in advance.
Here is an example of the code:
var app = angular.module(
'VarianceAnalysis', ['ngRoute', 'ngAnimate', 'mgcrea.ngStrap', 'mgcrea.ngStrap.tooltip', 'mgcrea.ngStrap.helpers.dateParser', 'SharedServices']
)
.service('varianceService', function () {
var variances = {};
return {
redirect: function (path) {
$location.path(path);
},
getHttpVariances: function (month1, month2) {
var url = "/Home/GetVariances?month_1=";
url += month1;
url += "&month_2="
url += month2;
url += "&forwardBilling=true"
$http.get(url).success(function (data) {
variances = data;
return data;
});
return {};
},
getVariances: function () {
return variances;
}
};
})
.config(['$routeProvider',
function ($routeProvider) {
$routeProvider.
when('/MainPage', {
templateUrl: 'mainpage.html',
controller: 'MainPageCtrl'
}).
when('/Variance/:type', {
templateUrl: 'variance.html',
controller: 'VarianceCtrl'
}).
otherwise({
redirectTo: '/MainPage'
});
}])
.controller('VarianceCtrl', ['$scope', 'varianceService', function ($scope, $http, $location, $routeParams) {
$scope.variance_type = varianceService.getVariances();
}])
.controller('MainPageCtrl', ['$scope', 'varianceService', function ($scope, $http, $location) {
$scope.go = function (month1, month 2) {
$scope.variances = varianceService.getHttpVariances(month1, month2);
}]);

The problems lies in the bracket notation of injecting services in your function..
What you inject in the bracket notation must also be present in the function definition..
e.g.
controller('MyCtrl', ['$scope', '$http', 'varianceService', function($scope, $http, varianceService) {
}]);
so in relation to your code above.. it should be like this..
.controller('VarianceCtrl', ['$scope', '$http', '$location', '$routeParams', 'varianceService', function ($scope, $http, $location, $routeParams, varianceService) {
$scope.variance_type = varianceService.getVariances();
}])
.controller('MainPageCtrl', ['$scope', '$http', '$location', 'varianceService', function ($scope, $http, $location, varianceService) {
$scope.go = function (month1, month 2) {
$scope.variances = varianceService.getHttpVariances(month1, month2);
}]);
just as how you have ordered the injected services in your bracket notation, it must also pertain the same order in your function definition.

Change this
.controller('VarianceCtrl', ['$scope', 'varianceService', function ($scope, $http, $location, $routeParams) {
$scope.variance_type = varianceService.getVariances();
}])
to
.controller('VarianceCtrl', ['$scope', '$http', '$location', '$routeParams', 'varianceService', function ($scope, $http, $location, $routeParams, varianceService) {
$scope.variance_type = varianceService.getVariances();
}])

Unknown scope provider $scope

I am trying to inject $scope but it's not working. This is my code:
var appCtrl = app.controller(
'AppCtrl',
function ($scope, $resource, $location, $route, sharedProperties) {}
);
appCtrl.prepData = function (
$q, $scope, $resource, $location, $route, sharedProperties) {}
I am trying to define a function after getting the appCtrl variable. But $scope wouldn't work there. Any idea how to resolve this issue?
