Login Controller -

 var myapp = angular.module('myApp', ['ngRoute']);

    myapp.config(["$routeProvider", function($routeProvider) {
        $routeProvider

        })
        .otherwise({
            redirectTo: '/'
        });

    }]);

    myapp.controller('loginctrl', ['$scope', '$route', '$http', '$routeParams', '$location', 
                     function($scope, $route, $http, $routeParams, $location) {
        console.log("im a controller");



        $scope.login = function() {
            //console.log($scope.user);

                    console.log(response.data);
                    // called asynchronously if an error occurs
                    // or server returns response with an error status.
                });

        };
    }]);


    myapp.controller('addusersctrl',['$scope','$http',function($scope,$http){
        console.log("im a controller");



        $scope.login = function() {
            //console.log($scope.user);

            // $http.post('/login',$scope.user).success(function(response){
            //  console.log(response);

     var express = require('express')

        app.post('/login',function(req, res){
            console.log(req.body);

        // // direct way uncomment this and try to http request

        //  client.post("http://192.168.1.6:8080/RestTGRP/TGRP/checkAPI", function (data, response) {

            });

Whenever we are trying to navigate from login to addusers page, we are getting 404 Page Not Found Error. How to redirect a page from controller page?

Answer 1

It is most likely the way you have provided the templateUrl in the route configuration. My suggestion would be to figure out your docroot, it is most likely the project folder in case of nodejs and provide a complete path relative to the docroot in the templateUrl and not the "../" style representation. What you are trying to do is provide the templateUrl relative to the login controller.

For example if your project structure is:

 nodeproject/
         |-> js/
         |-> loginPage/    
                |-> views/

Your templateUrl in the routeConfig would be:

myapp.config(["$routeProvider", function($routeProvider) {
    $routeProvider

    .when('/addusers', {
        controller: 'addusersctrl',
        templateUrl: '/loginPage/views/addusers.html'
    })
    .otherwise({
        redirectTo: '/'
    });

}]);
