Is there any better way to display POST request in Angular Js

I have used both PUT and POST request to modify and create a data. But the thing is POST request is not working properly. When i click on add() button , automatically POST request is generating id in the json-data before filling the information in the text fields.
Moreover data should be updated when I click on the save() button . Below I have pasted my code, if I have made any mistake tel me know and I appreciate every one whomever gives any information.
HTMl :
<button class="btn btn-info" ng-click="addmode()"> Add </button>
<button class="btn btn-success" ng-show="editMode" ng-click="saveinfo()"> Save </button>
Angular JS :
$scope.addmode = function(information) {
var postinfo = information;
$http({
url:'http://localhost:3000/contacts' ,
method : 'POST',
data : postinfo
})
.then(
function successCallback(response) {
$scope.selectedcontact = '';
console.log(response.data)
},
function errorCallback(response) {
console.log("Error : " + response.data);
});
};

First create services/api.js
angular.module('app')
.factory('api', function ($rootScope,ApiEndpoint, $http, $q,$timeout,$cookies) {
var get = function (url) {
var config = {url: url, method: ApiEndpoint.Methods.GET};
return this.call(config);
};
var del = function (url) {
var config = {url: url, method: ApiEndpoint.Methods.DELETE};
return this.call(config);
};
var post = function (url, data) {
var config = {url: url, method: ApiEndpoint.Methods.POST, data: data};
return this.call(config);
};
var put = function (url, data) {
var config = {url: url, method: ApiEndpoint.Methods.PUT, data: data};
return this.call(config);
};
return {call: call, get: get, post: post, del: del, put: put};
});
After create service/apiendpoint.js
angular.module('app')
.constant('ApiEndpoint', {
ServerUrl: 'http://localhost/',
BaseUrl: 'http://localhost/',
Methods: {GET: 'GET', POST: 'POST', PUT: 'PUT', DELETE: 'DELETE'},
Models: {
test:"fe_api/test",
},
URLS: {
QUERY: 'app/'
},
getUrl: function (url) {
var host=window.location.host;
var protocol=window.location.protocol ;
return protocol+"//"+host+"/"+url;
}
});
**Create model handler **
angular.module('app')
.factory('ApiService', function (api, ApiEndpoint) {
var getModel = function (url_part)
{
var url = ApiEndpoint.getUrl(ApiEndpoint.URLS.QUERY) + url_part;
return api.get(url);
};
var getModelViaPost = function (url_part, data)
{
var url = ApiEndpoint.getUrl(ApiEndpoint.URLS.QUERY) + url_part;
return api.post(url, data);
};
var postModel = function(model_name, data) {
var url = ApiEndpoint.getUrl(ApiEndpoint.URLS.QUERY) + model_name;
return api.post(url, data);
};
var putModel = function(model_name, data) {
var url = ApiEndpoint.getUrl(ApiEndpoint.URLS.QUERY) + model_name;
return api.put(url, data);
};
var deleteModel = function(model_name, id) {
var url = ApiEndpoint.getUrl(ApiEndpoint.URLS.QUERY) + model_name + '/' + id;
return api.delete(url);
};
return {
getModel: getModel,
postModel : postModel,
putModel : putModel,
deleteModel : deleteModel,
getModelViaPost : getModelViaPost
};
});
write API call in the controller
var data = {
wut_token: $cookies.data,
};
ApiService.postModel(ApiEndpoint.Models.test, data).then(function (response) {
if (response.SUCCESS == "FALSE") {
} else {
}
})

How to call nest factory in Angularjs?

Hi I am developing web application in angularjs. I have requirement below. I have one factory. I have added code snippet below.
myapp.factory('sadadpaymentapi', ['$http', '$cookieStore', 'cfg', 'ScrollFunction', 'leaselisting', function ($http, $cookieStore, cfg, ScrollFunction, leaselisting) {
var sadadpaymentapiobject = {};
var baseurl = cfg.Baseurl;
var LoginID = $cookieStore.get("LoginID");
var cookiePreferredLanguage = $cookieStore.get('PreferredLanguage');
var urlapi = baseurl + "api/ServiceRequest/CreateRSSedad/";
sadadpaymentapiobject.callsadad = function (PaymentType) {
leaselisting.leaselisting().then(function (response) {
//Problem in calling
}, function (error) { });
var request = {
url: urlapi,
method: 'POST',
data: {
SRActivityID: LoginID,
PaymentType: PaymentType,
PaymentAmount: "100"
},
headers: ScrollFunction.getheaders()
};
return $http(request);
}
return sadadpaymentapiobject;
}]);
Here is my second factory leaselisting
myapp.factory('leaselisting', ['$http', '$cookieStore', 'cfg', 'ScrollFunction', function ($http, $cookieStore, cfg, ScrollFunction) {
var leaselistingobject = {};
var baseurl = cfg.Baseurl;
var LoginID = $cookieStore.get("LoginID");
var cookiePreferredLanguage = $cookieStore.get('PreferredLanguage');
leaselistingobject.leaselisting=function(){
var requestObj = {
url: "api/ServiceRequest/GetROLSPSRLeaseList/",
data: {
LoginID: LoginID,
RSAccountNumber: $cookieStore.get("AccountNumber")
},
headers: ScrollFunction.getheaders()
};
$http(requestObj).then(function (response) {
}, function (error) {
});
}
return leaselistingobject;
}]);
I have found error in below line
leaselisting.leaselisting().then(function (response) { //Problem in calling
}, function (error) { });
May i am i doing anything wrong in the above code? May i know is it possible to call one factory from another? The response i get from leaselisting i want to pass it in callsadad function of sadadpaymentapi. So can someone hep me in the above code? I am getting error Cannot read property 'then' of undefined in the leaselisting.leaselisting().then(function (response) {},function(error){});
Also is there any way I can directly inject factory like payment amount: inject factory something like this?

I assume, that leaselistingobject.getValue is an asynchronous function.
So first of get your value :
leaselistingobject.getValue = function(){
var requestObj = {
url: "api/ServiceRequest/getValue/"
};
return $http(requestObj).then(function (response) {
return response.data;
});
}
And then use it. To let all async actions finish we use angulars $q.Here you can find a small tutorial.
myapp.factory('sadadpaymentapi', ['$http', '$cookieStore', 'cfg', 'ScrollFunction', 'leaselisting', '$q',function ($http, $cookieStore, cfg, ScrollFunction, leaselisting, $q) {
var sadadpaymentapiobject = {};
var baseurl = cfg.Baseurl;
var LoginID = $cookieStore.get("LoginID");
var cookiePreferredLanguage = $cookieStore.get('PreferredLanguage');
var urlapi = baseurl + "api/ServiceRequest/CreateRSSedad/";
sadadpaymentapiobject.callsadad = function (PaymentType) {
var leastListingPromise = leaselisting.leaselisting();
var getValuePromise = leaselisting.getValue();
$q.all([leastListingPromise, getValuePromise]).then(function (responses) {
//Here you have both responses in an array
var request = {
url: urlapi,
method: 'POST',
data: {
SRActivityID: LoginID,
PaymentType: PaymentType,
PaymentAmount: responses[1]
},
headers: ScrollFunction.getheaders()
};
return $http(request);
});
}
return sadadpaymentapiobject;
}]);
To make leaselisting() return the response of the request change the end of the function from
$http(requestObj).then(function (response) {
}, function (error) {
});
to
return $http(requestObj).then(function (response) {
return response.data;
}, function (error) {
});
If wont do anything about possible errors you can omit the error function part:
return $http(requestObj).then(function (response) {
return response.data;
});

Knockout JS Validation not working

I am a newbie in Knockout JS. i want to apply validations in KO. i have used plugin knockout.validation.min.js . I have implemented it like this but not working
My View Model
$(document).ready(function myfunction() {
ko.applyBindings(new EmployeeKoViewModel());
})
var EmployeeKoViewModel = function () {
var self = this;
self.EmpId = ko.observable()
self.Name = ko.observable("").extend({ required: { message: "please enter employee name " } });
self.City = ko.observable("").extend({ required: { message: "please enter employee city " } });
self.Employees = ko.observableArray();
//GetEmployees();
var EmpData = {
EmpId: self.EmpId,
Name: self.Name,
City: self.City,
};
function GetEmployees() {
$.ajax({
type: "GET",
url: "/Employee/About",
}).done(function (data) {
self.Employees(data);
}).error(function (ex) {
alert("Error");
});
}
self.save = function () {
var EmployeeKoViewModel.errors = ko.validation.group(self);
if (!EmployeeKoViewModel.errors().length <= 0) {
EmployeeKoViewModel.errors.showAllMessages();
return false;
}
$.ajax({
type: "POST",
url: "/Employee/Save",
data: ko.toJSON(EmpData),
contentType: "application/json",
success: function (data) {
self.EmpId(data.EmpId);
GetEmployees();
},
error: function () {
alert("Failed");
}
});
//Ends Here
};
}
I have created a fiddle it is working when i comment GetEmployees() method but not working with it

At this line
var EmployeeKoViewModel.errors = ko.validation.group(self);
you are trying to create a variable, but the syntax is like creating an object with a property which is of course invalid. In order to fix this you can initialize your object first:
var EmployeeKoViewModel = {};
EmployeeKoViewModel.errors = ko.validation.group(self);
if (!EmployeeKoViewModel.errors().length <= 0) {
EmployeeKoViewModel.errors.showAllMessages();
return false;
}
Here is a working jsFiddle

How to call web service in sencha touch 2?

I 'm beginner in sencha touch 2 and i need to call webservice.The code of web service is:
public function loginAction()
{
$request = $this->getRequest();
$username = $request->request->get('username');
$password= $request->request->get('password');
$success=false;
$token="error";
$error="test";
$userManager = $this->get('fos_user.user_manager');
$user = $userManager->findUserBy(array('username' => $username));
if (! $user)
{
$token="username not exists";
$success=false;
}
else
{
$password_user=$user->getPassword();
$factory = $this->get('security.encoder_factory');
$encoder = $factory->getEncoder($user);
$password = $encoder->encodePassword($password, $user->getSalt());
if ($password!=$password_user)
{
$token="password incorrect";
$success=false;
}
else
{
$token="logged";
$success=true;
}
}
$info= array("token" => $token);
$res=array("success"=> $success);
$res = array("status"=> $res,
"resultat"=>$info
);
$serializer = $this->get('jms_serializer');
$response = $serializer->serialize($res,'json');
return new Response($response);
}
and i make in project sencha a view: Login.js and a controller: Login.js. The problem is in calling the web service and the code in controller Login.js:
Ext.define('Sample.controller.Login', {
extend: 'Ext.app.Controller',
config: {
refs: {
loginView: 'loginview',
mainMenuView: 'mainmenuview'
},
control: {
loginView: {
signInCommand: 'onSignInCommand'
},
mainMenuView: {
onSignOffCommand: 'onSignOffCommand'
}
}
},
// Session token
sessionToken: null,
// Transitions
getSlideLeftTransition: function () {
return { type: 'slide', direction: 'left' };
},
getSlideRightTransition: function () {
return { type: 'slide', direction: 'right' };
},
onSignInCommand: function (view, username, password) {
console.log('Username: ' + username + '\n' + 'Password: ' + password);
var me = this,
loginView = me.getLoginView();
if (username.length === 0 || password.length === 0) {
loginView.showSignInFailedMessage('Please enter your username and password.');
return;
}
loginView.setMasked({
xtype: 'loadmask',
message: 'Signing In...'
});
Ext.Ajax.request({
url: 'http://localhost/dawinilastversion/web/app_dev.php/api/login',
method: 'post',
params: {
username: username,
password: password
},
success: function (response) {
var loginResponse = Ext.JSON.decode(response.responseText);
if (loginResponse.success === "true") {
// The server will send a token that can be used throughout the app to confirm that the user is authenticated.
me.sessionToken = loginResponse.sessionToken;
me.signInSuccess(); //Just simulating success.
} else {
me.signInFailure(loginResponse.message);
console.log('erreur.');
}
},
failure: function (response) {
me.sessionToken = null;
me.signInFailure('Login failed. Please try again later.');
}
});
},
signInSuccess: function () {
console.log('Signed in.');
var loginView = this.getLoginView();
mainMenuView = this.getMainMenuView();
loginView.setMasked(false);
Ext.Viewport.animateActiveItem(mainMenuView, this.getSlideLeftTransition());
},
singInFailure: function (message) {
var loginView = this.getLoginView();
loginView.showSignInFailedMessage(message);
loginView.setMasked(false);
},
onSignOffCommand: function () {
var me = this;
Ext.Ajax.request({
url: 'http://localhost/dawinilastversion/web/app_dev.php/api/login',
method: 'post',
params: {
sessionToken: me.sessionToken
},
success: function (response) {
// TODO: You need to handle this condition.
},
failure: function (response) {
// TODO: You need to handle this condition.
}
});
Ext.Viewport.animateActiveItem(this.getLoginView(), this.getSlideRightTransition());
}
});
And the web service login work with success:

you need to go one step deeper into the JSON response:
if (loginResponse.status.success === true)
and check against the bool true not the string true

Using a factory inside another factory AngularJS

I have a module...
angular.module('myModule', []);
And then a factory
angular.module('myModule')
.factory('factory1', [
function() {
//some var's and functions
}
]);
And then another factory
angular.module('myModule')
.factory('factory2', [
function() {
//some var's and functions BUT I want to use some var's from factory1
}
]);
But I want to use some variables from factory1 inside factory2, how can I inject factory1 into factory2?

This is what I would do:
On Factory One
angular.module('sampleApp')
.factory('factory1', function() {
var factory1 = {};
factory1.method1 = function () {
return true;
};
factory1.method2 = function () {
return "hello";
};
return factory1;
}
);
On Factory Two
angular.module('sampleApp')
.factory('factory2', ['factory1',
function(factory1) {
var factory2 = {};
factory2.method3 = function () {
return "bye vs " + factory1.method2();
};
return factory2;
}
]);

This is what i did and worked fine. Call SessionPresenters from Session
angular.module('tryme3App')
.factory('Session', function ($resource, DateUtils, SessionPresenters) {
return $resource('api/sessions/:id', {}, {
'query': { method: 'GET', isArray: true},
'get': {
method: 'GET',
transformResponse: function (data) {
data = angular.fromJson(data);
var result = SessionPresenters.get({id: data.id})
data.presenters = result;
return data;
}
},
'update': { method:'PUT' }
});
}).factory('SessionPresenters', function ($resource, DateUtils) {
return $resource('api/session.Presenters/:id', {}, {
'query': { method: 'GET', isArray: true},
'get': {
method: 'GET', isArray: true
},
'update': { method:'PUT' }
});
});
