I am using Angular 1.4.4 and Django 1.8. When i post data from Angular to Django view it comes in the form of whole data as key in the QueryDict.
So in view in debug mode when i evaluate request.POST it returns this
<QueryDict: {u'{"messagetitle":"","value":"","valueam":"","wrong_response":"","stop":"","messagekind":"1","undefined":"","messagetype":"3","state":"","language_id":1}': [u'']}>
Notice posted data is inside u'' as key and its value is [u'']
Angular dataservice code is this
function createDraft(data) {
return $http({
url: view_url + 'create_draft/',
method: 'POST',
data: data,
headers: {
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
}
})
}
Controller code
app.controller('message',function($scope, $ngBootbox, dataservice, $http){
$scope.formData = {
"messagetitle":"", "value":"", "valueam":"",
"wrong_response": "", "stop": "", "messagekind": "1",
"undefined_response": "", "messagetype":"3",
"state": "", "language_id":1
};
saveDraft = function(){
dataservice.createDraft($scope.formData).then(
function(res) {
$ngBootbox.alert("<div class='alert-success alert_box'>Draft Saved</div>")
},
function(res) {
var error_message = res['statusText'].trim();
if (error_message === '')
error_message = 'Error Occurred';
$ngBootbox.alert("<div class='alert-warning alert_box'>" + error_message + "</div>")
})
}
saveDraft function is called from angular template(which is html form) on button click.
Let me know what i am doing wrong here. I have tried some answers on stackoverflow but could not find any question/answer which addresses my specific problem.
PS:
I know i can do json.loads(request.body) but i need to post data in django's request.POST
Use $.param(data) instead of data in your service

I am new to angular-js and building a simple to-do application. I am creating a task and displaying the created task in a html table using ng-repeat. But the problem is that after posting the data, $scope.tasks variable is updated on controller side, but not in view. The view updates after refreshing the web page only and the task is added to html table. How can I make the view update after creating the task. Thanks in advance. Here is my code:
In my controller:
var app = angular.module('MyApp', ['ngMaterial', 'ngMessages']);
app.controller('DemoCtrl', function($scope,$mdSidenav,$mdDialog,$interval,$http,$mdToast) {
$scope.tasks = [];
_refreshTaskData(); //initial refresh
$scope.submitForm = function() {
var description = "";
var taskId = "";
$scope.formData = {
taskId: $scope.taskId,
description: $scope.description,
};
$http({
method: "POST",
url: 'savetask',
data: angular.toJson($scope.formData),
headers : {
'Content-Type': 'application/json',
}
}).then(_success, _error);
};
function _refreshTaskData() {
$http({
method : 'GET',
url : 'getTask',
}).then(function(res) { // success
$scope.tasks = res.data;
}, function(res) { // error
console.log("Error: " + res.status + " : " + res.data);
});
}
function _success(res) {
$mdDialog.hide();
console.log('in success function');
_refreshTaskData(); ;
}
function _error(res) {
//error handling
}
});
In my view:
<table>
<tr ng-repeat=" t in tasks">
<td>{{t.id}}</td>
<td>{{t.description}}</td>
</tr>
</table>
You must understand that these JS frameworks are asynchronous. Now what happens is, if you do an API call and make another API call whose result is based on the first one, the console does not wait for the result from one API and directly moves forward. SO what's happening in your case is sometimes/many times, before the POST call is served, the controller is not able to get fresh data with GET in time, thus not updating the view. What you can possibly do is enforce the GET only when POST is served
$http({
method: "POST",
url: 'savetask',
data: angular.toJson($scope.formData),
headers : {
'Content-Type': 'application/json',
}
}).then(function(res){
$http({
method : 'GET',
url : 'getTask',
}).then(function(res) { // success
$scope.tasks = res.data;
}, function(err) { // error
console.log("Error: " + err.status + " : " + err.data);
});
});
It would be best if you are sending a success message from the backend and checking before GET call
I think you are not calling _refreshEmployeeData at any point of time. If you add that instead of _refreshTaskData in your JS, then you will be able to see the result in view.
Also kindly use ng-init to call the _refreshEmployeeData in the controller. That would be the best way to initialize the fields.
I tried to make a post request from ionic to web api this way
ionic code
$http({
url: 'http://localhost:1449/api/IonicApi',
method: "POST",
data: {
firstName : "a",
lastName : "b",
email : "ab#ab.com"
},
headers: { 'Content-Type': "application/x-www-form-urlencoded; charset=UTF-8" }
}).then(function (response) {
// success
$ionicPopup.alert({
title: 'Your Name is '+$scope.man.firstName + ' '+$scope.man.lastName,
template: 'It might taste good'
})
}, function (response) { // optional
// failed
console.log('failed');
});
and the c# part is
public IHttpActionResult Post(tblPerson person)
{
db = new MobileDBEntities();
db.tblPersons.Add(person);
db.SaveChanges();
return Ok();
I tried from postman to post data it was working. But from Ionic it is passing null data of object
What wrong did I make here?
Postman screenshot I am adding here
Is it possible to call you api like below where obj is your data
$http.post('http://localhost:1449/api/IonicApi',obj).success(function(){
}).error(function()
{
});
Hi I am developing one application using web api2 and angularjs. Finding hard time to send data to web api methods. I am having problem to send data as objects n PUT and POST methods. In delete and getbyid methods i am able to send single parameter but i am not able to send data as object. I am receiving null as below.
I am calling as below using angularjs.
this.saveSubscriber = function (sub) {
return $http({
method: 'post',
data: sub,
url: '/NCT_Users/',
// contentType: "application/json"
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
});
}
If i comment header and uncomment contentType in above code I am getting totally null object as below.
May i know why i am not able to bind object to model? Any help would be appreciated. Thank you.
var person = {firstName:"John", lastName:"Doe", age:46};
$http.post('url', person)
.success(function (response){
alert(response);
});
accesstoken is defined variable.you can define your variables to pass it to server
var person = {
firstName:"John",
lastName:"Doe",
age:46
};
$http.post('url', person)
.success(function (response) {
alert(response);
});
try this way.
var sub = {
User_CreatedDate: "",
UserEmailId: "",
User_Id: "",
User_MobileNum: "",
User_Name: "",
User_Password: "",
User_Role: "",
User_Status: "",
User_UpdateDate: ""
};
$http.post('/NCT_Users/', sub).success(function (response) { alert(response); });
the fields are filled by you
It happens like this because you are sending an JS Object via an 'application/x-www-form-urlencoded' header. You have to send the data as parameters, try this updated function:
this.saveSubscriber = function (sub) {
return $http({
method: 'POST',
data: $.param(sub),
url: '/NCT_Users/',
headers : { 'Content-Type': 'application/x-www-form-urlencoded' }
});
}
I have an application made with .NET core framework and pure html in the front end. I was using AJAX to post and get data.
I am new to Angular and decided to convert the front end of the application to Angular for learning purposes.
For Example, I have a button that will change the state of employees from 'Billed' to 'Available' state. The ID for available state is defined in the back end and it is '1'.
//MOVE TO BENCH BUTTON CLICK
$(document).ready(function()
{
var allVals = [];
$("#MoveToBench").click(function()
{
$('input:checkbox:checked').each(function () {
allVals.push($(this).val());
});
for (i = 0;i<allVals.length;i++){
PostBenchList(allVals[i])
}
function PostBenchList(entityId) {
var data = 'entityID='.concat(entityId).concat('&nextStateId=1');
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "http://localhost:1783/api/Workflow?"+data,
data: data,
dataType: "text",
success: function (data) {
location.reload();
alert("Successfully added the selected Employees to TalentPool");
},
fail: function (error) {
Console.Log(error);
}
})
}
});
});
The above code is taking an array of entityID's as input. For the Angular application, the array is not required as only one entity ID will be passed.
The API controller in the backend is :
// POST api/values
[HttpPost]
public void Post(int entityId, int nextStateId)
{
JObject jsonObject = JObject.Parse(System.IO.File.ReadAllText("Config.Json"));
string jsonFile = jsonObject.GetValue("WorkfowJsonFileLocation").ToString();
var nextState = _stateServices.Get(nextStateId);
var handler = new WorkflowHandler(nextState, jsonFile, _entityServices, 1, _stateServices, _subStateServices, _appServices);
handler.PerformAction(entityId);
}
The above code worked for me and it would change the state ID of the employee(EntityID)to 1(nextStateId)
Now I have a button in AngularJS and I want it to do the same action. How would I achieve this? As I am still in the procedure of learning, I don't have a clue how to do this. Can anyone help me to achieve this? This would help me to learn and do all similar buttons.
Thank You.
You can use ng-click and call a function to post the data,
HTML:
<button ng-click="PostData()">
Click to POST
</button>
Controller:
app.controller('PostController',['$scope',function($scope)
{
$scope.sendPost = function() {
var data = $.param({
json: JSON.stringify({
name: $scope.newName
})
});
$http.post("/echo/json/", data).success(function(data, status) {
$scope.hello = data;
})
}
}]);
DEMO APP
$http({method: 'POST', url: 'http://localhost:5001/products', data: {token: $scope.product.token}}).success(
function () {
alert('success');
}
);
In the pyramid side, request.POST show that NOVars: Not a form request. Not an HTML form submission( Content-Type: application/json)
I am using cornice to provide my api(/products) and I thinks it is pyramid's problem.
Does anyone have a solution?
Angular sends the post body (data) as application/json while forms are normally sent as application/x-www-form-urlencoded. Pyramid parses the body and let you access it in request.POST when it's encoded as a normal form.
It is not be possible to represent every data encoded the Angular way (json) as a key/value pair like is provided by pyramid API.
[
1,
2,
3,
4
]
Solution on Pyramid side
It can be solved per view or globally
Per view
This is the pyramid way and the most flexible way to handle this.
#view_config(renderer='json')
def myview(request):
data = request.json_body
# deal with data.
return {
"success" : True
}
Globally
Pyramid can most likely be set to assume a body encoded as application/json is an object and its properties be put in request.POST.
Solution on Angular side
As with the pyramid side, it can be solved per request and globally.
Per request
You need to send the data the way forms are normally sent:
$http({
method: 'POST',
url: url,
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
transformRequest: function(obj) {
var str = [];
for(var p in obj) {
if (obj.hasOwnProperty(p)) {
str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
}
}
return str.join("&");
},
data: xsrf
}).success(function () {});
Globally
To send posts as form by default, configure the $httpProvider to do so.
angular.module('httpPostAsForm', [])
.config(['$httpProvider', function ($httpProvider) {
$httpProvider.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded";
$httpProvider.defaults.transformRequest.unshift(function (obj) {
var str = [];
for(var p in obj) {
if (obj.hasOwnProperty(p)) {
str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
}
}
return str.join("&");
});
}]);
Then include this module in your app:
angular.module("app", ["httpPostAsForm"]);
AngularJS $http.post is different from jquery's. The data you pass is not posted as a form but as json in the request body. So your pyramid view can not decode it as usual. You have to either:
directly access the request body and decode it in your pyramid view;
or modify your angularjs code to post your data as form content : see this other question in stackoverflow
the answer is angular $post do OPTIONS request first and then do the POST request, get data form the request.json_body
Use req.json_body if you post some json-decoded content. req.GET, req.POST, req.params only cope with from submissions. Btw, $http -> ngResource -> restangular ...
Try setting contenttype in $http, something like below.
$http(
{
url: url,
contentType: "application/json",
data: data,
method: method
})
.success(function (response) {
successcb(response);
}).error(function (data, status, headers, config) { errorcb(data); });
};
You can simply get the POST data this way:
query = json.loads(request.body)
