ASP.Net WEB API AND ANGULAR Not outputting one column vs another - sql-server

I was able to set up a asp.net web api and scaffolding to my sql server database. The return of the records from sql server appears to be JSON. The model has a few tables linked to each other by foreign keys and only has 2 records right now. Comp_Id = 1 and 2. The results to my local api looks like this:
[{"ASSOC_INC_OFF":[{"OFFICERINVOLVEDs":[],"AIO_ID":1,"COMP_ID":1,"OFCNUM":1,"LINK_TYPE":null}],"CRITICALINCIDENTs":[{"CIType":"Physical Force resulting in Death or Serious Bodily Injury","CINotice":null,"CIMonitorRolledOut1":null,"CIDAMonitored":null,"CIOIMQuestions":null,"CICharged":null,"CIMonitor1":null,"CIMonitor2":null,"CINotes":null,"CIOfcCharges":null,"CIOutcome":null,"COMP_ID":1,"RolledOut_DT":null,"CI_ID":1,"CINotice_DT":"2016-01-07T00:00:00","CIOIMAllegNotes":null,"CIMonitorRolledOut2":null,"CIMonitorRolledOut3":null,"CIMonitorRolledOut4":null,"CIMonitorRolledOut5":null,"CIMonitorRolledOut6":null,"CIMonitorRolledOut7":null}],"COMP_ID":1,"FileNum":"case1","Received_DT":"2016-01-21T00:00:00","Completed_DT":null,"OIMIntake_DT":null,"Status":null,"Occurred_DT":null,"ComplaintType":null,"Source":"Chiefs Office","Precinct":"District 2","AddrCity":null,"AddrState":null,"AddrZip":null,"CaseSummary":null,"IABNotified_DT":null,"ClosureLetSent_DT":null,"CaseType":null,"OIMOutcome":null,"InitialFinding":null,"ClosedFindings":null,"OIMRecFinding":null,"timestamp":null,"Department":"DSD","Address":null,"DeclineReason":null,"Filenum2":null,"Filenum3":null,"OIMDiscRev_DT":null,"OIMInvRev_DT":null,"OIMInvRoute_DT":null,"OIMDiscRoute_DT":null,"CRORoute_DT":null},{"ASSOC_INC_OFF":[],"CRITICALINCIDENTs":[{"CIType":"Officer/Deputy-Involved Shooting","CINotice":null,"CIMonitorRolledOut1":null,"CIDAMonitored":null,"CIOIMQuestions":null,"CICharged":null,"CIMonitor1":null,"CIMonitor2":null,"CINotes":null,"CIOfcCharges":null,"CIOutcome":null,"COMP_ID":2,"RolledOut_DT":null,"CI_ID":2,"CINotice_DT":null,"CIOIMAllegNotes":null,"CIMonitorRolledOut2":null,"CIMonitorRolledOut3":null,"CIMonitorRolledOut4":null,"CIMonitorRolledOut5":null,"CIMonitorRolledOut6":null,"CIMonitorRolledOut7":null}],"COMP_ID":2,"FileNum":"cw1","Received_DT":"2016-01-03T00:00:00","Completed_DT":null,"OIMIntake_DT":null,"Status":"Active","Occurred_DT":null,"ComplaintType":null,"Source":"Citizen Walk-in","Precinct":"District 7","AddrCity":null,"AddrState":null,"AddrZip":null,"CaseSummary":null,"IABNotified_DT":null,"ClosureLetSent_DT":null,"CaseType":"District-Bureau","OIMOutcome":"Satisfactory","InitialFinding":"Formal","ClosedFindings":null,"OIMRecFinding":"Decline","timestamp":null,"Department":"DSD","Address":null,"DeclineReason":"Body Worn Camera","Filenum2":null,"Filenum3":null,"OIMDiscRev_DT":null,"OIMInvRev_DT":null,"OIMInvRoute_DT":null,"OIMDiscRoute_DT":null,"CRORoute_DT":null}]
I am able to bind COMP_ID to my view but when I add in CIType, nothings appears.
console.log($scope.complaints) returns:
My Controller looks like this:
app.controller('UpdateController', function ($scope, ComplaintService) {
getCities();
function getCities() {
ComplaintService.getCities()
.success(function (complaints) {
$scope.complaints = complaints;
})
.error(function (error) {
$scope.status = 'Unable to load customer data: ' + error.message;
});
}
});
My service looks like this:
app.factory('ComplaintService', ['$http', function ($http){
var urlBase = 'http://localhost:63942/api';
var ComplaintService = {};
ComplaintService.getCities = function () {
return $http.get(urlBase+ '/complaints');
};
return ComplaintService;
}]);
and my index looks like this:
<div class="row">
<div class="col-md-3" ng-controller="UpdateController">
<table class="table">
<tr>
<th>Id</th>
<th>CI TYPE</th>
<tr ng-repeat="a in complaints">
<td>{{a.COMP_ID}}</td>
<td>{{a.CIType }}</td>
</table>
</div>
I am certainly confused about why I can render out only COMPID but not the rest of this api contents as it is all listed under localhost:###/api/complaints.

var someResultArray = [];
$scope.complaints.forEach(function(elem){
//basically checks if this exists in the object to avoid undefined issues
if(elem.ASSOC_INF_OFF){
elem.ASSOC_INF_OFF.forEach(function(assoc){
//do something with each assoc, ex: push it to another array
someResultArray.push(assoc);
});
}
});
an object in javascript can be treated by dotting yourself down, or you can also address its content by index, even though its an object. So you could write elem["ASSOC_INF_OFF"], and it would still work.

Unable to bind Json Data with Table Header using AngularJS

Im getting data in this format from api, but when i try binding it to table using angularjs it is creating empty space instead of values. Im also getting more then one table from some Api's please explain who to bind different datatables in different tables too. thanks
{"Table":
[{
"SchoolId":1,
"schoolname":"Microsoft",
"SCHOOLCODE":"29911583",
"WEBSITE":"JLR",
"USEREMAIL":"faucibus#aliquamiaculislacus.org",

Angular Controller
SMSApp.factory('GetStudentService', function ($http) {
studobj = {};
studobj.getAll = function () {
var stud=[];
stud = $http({ method: 'Get', url: 'http://localhost:58545/api/Student?Studentid=1' }).
then(function (response) {
return response.data;
});
return stud;
};
return studobj;
});
SMSApp.controller('studentController', function ($scope, GetStudentService) {
$scope.msg = "Welcome from Controller";
GetStudentService.getAll().then(function (result) {
$scope.school = result;
console.log(result);
});
});
HTML Code
<tbody ng-controller="studentController">
<tr ng-repeat="schools in school track by $index">
<td>{{schools.SchoolId}}</td>
<td>{{schools.schoolname}}</td>
<td>{{schools.SCHOOLCODE}}</td>
<td>{{schools.WEBSITE}}</td>
<td>{{schools.USEREMAIL}}</td>
</tr>
</tbody>
WHAT I GET
Change in your Angular Controller :
SMSApp.controller('studentController', function ($scope, GetStudentService) {
$scope.msg = "Welcome from Controller";
GetStudentService.getAll().then(function (result) {
/********************* Changed Here ********************/
$scope.school = JSON.parse(result._body); // Or only JSON.parse(result)
$scope.school = $scope.school.table;
});
});
And your HTML Code :
<tbody ng-controller="studentController">
<tr ng-repeat="schools in school track by $index">
<td>{{schools.SchoolId}}</td>
<td>{{schools.schoolname}}</td>
<td>{{schools.SCHOOLCODE}}</td>
<td>{{schools.WEBSITE}}</td>
<td>{{schools.USEREMAIL}}</td>
</tr>
</tbody>
Naming the data school is confusing. Do instead:
GetStudentService.getAll().then(function (data) {
$scope.tableObj = data;
console.log(data);
});
<tbody ng-controller="studentController">
<tr ng-repeat="school in tableObj.Table track by school.SchoolId">
<td>{{school.SchoolId}}</td>
<td>{{school.schoolname}}</td>
<td>{{school.SCHOOLCODE}}</td>
<td>{{school.WEBSITE}}</td>
<td>{{school.USEREMAIL}}</td>
</tr>
</tbody>
From the Docs:
Best Practice: If you are working with objects that have a unique identifier property, you should track by this identifier instead of the object instance, e.g. item in items track by item.id. Should you reload your data later, ngRepeat will not have to rebuild the DOM elements for items it has already rendered, even if the JavaScript objects in the collection have been substituted for new ones. For large collections, this significantly improves rendering performance.
— AngularJS ng-repeat API Reference
Just replace your result with result.Table in your controller because if you properly see your response it is inside "Table" named array. Try this you should be able to see your records
SMSApp.controller('studentController', function ($scope, GetStudentService) {
$scope.msg = "Welcome from Controller";
GetStudentService.getAll().then(function (result) {
$scope.school = result.Table;
console.log(result);
});
});
Note: I have replaced your API call in the jsfiddle link with the response mentioned in the question.

Not fetching data with Angular JS

I'm trying to build an app with Angular JS that fetches data from a Django REST API.
I have this script
var userListApp = angular.module('userListApp', ['ngResource']);
userListApp.factory('Classroom', function($resource) {
return $resource('/classrooms/:id/',
{'query': {method: 'GET', isArray:false}}
);
});
userListApp.controller('UsersController', function($scope, Classroom) {
Classroom.query(function(data) {
$scope.classrooms = data;
});
});
and this is the html
<div ng-app="userListApp">
<div ng-controller="UsersController">
<table class="table table-striped">
<thead>
<tr>
<th>Classroom</th>
<th>School</th>
<th>Academic year</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="classroom in classrooms">
<td>{{classroom.classroom}}</td>
<td>{{classroom.school}}</td>
<td>{{classroom.academic_year}}</td>
</tr>
</tbody>
</table>
</div>
</div>
But I'm getting this error in the console
Error: $resource:badcfg
Response does not match configured parameter
Error in resource configuration for action query. Expected response to contain an array but got an object (Request: GET /classrooms)
(from the error reference page of Angular JS)
I was looking at some answers here on stackoverflow, and came to this one, and I tried to do what they say
userListApp.factory('Classroom', function($resource) {
return $resource('/classrooms/:id/',
{method: 'classrooms', id: '*'},
{'query': {method: 'GET', isArray:false}}
);
});
And I'm getting no error, but no data either. There are, however, some tables on the webpage, like if it's trying to "catch" something, here's a screenshot
UPDATE:
I've tried to put this line
return $resource('/classrooms/?format=json',
Instead of this
return $resource('/classrooms/:id/',
on the Angular app, and there's no data, but, if I go to developer tools on Network -> XHR, I get the json data
[{"school":{"id":1,"school_name":"IPSIA F. Lampertico","address":"Viale Giangiorgio Trissino, 30","city":"Vicenza"},"academic_year":"2015/2016","classroom":"1^A","floor":0,"students":[{"classroom":1,"first_name":"Stefano","last_name":"Rossi","gender":"M","birthday":"1998-06-22"},{"classroom":1,"first_name":"Luca","last_name":"Possanzini","gender":"M","birthday":"1999-11-22"}]
but, as I said, that data is not shown on the tables in the html.
UPDATE 2:
After adding "?format=json'" to the resource url, I get the exact amount of rows (in my data I have three classrooms, so I get three rows in the HTML table), but no data in it.
UPDATE 3:
I've added this line to debug the code
userListApp.controller('UsersController', function($scope, Classroom) {
Classroom.query(function(data) {
$scope.classrooms = data;
console.log(data); <--- NEW LINE FOR THE DEBUG
});
});
and now I get this, on the console log
Your data is not in the correct format. The data you posted has missing }] in the end. Recheck your server response.
I replicated the whole scenario on my machine and your code worked perfectly fine.
HTML: Same as yours.
Script:
var userListApp = angular.module('userListApp', ['ngResource']);
userListApp.factory('Classroom', function($resource) {
return $resource('http://localhost:9000/classrooms/1', //changed this line only.
{'query': {method: 'GET', isArray:false}}
);
});
userListApp.controller('UsersController', function($scope, Classroom) {
Classroom.query(function(data) {
$scope.classrooms = data;
});
});
http://localhost:9000/classrooms/1 returns just the data that you specified with }] appended at the end.

How to echo JSON array as Smart Table data with Angluarjs

I'm pretty new to Angular, and trying to build a table using Smart Table based on data I'm fetching from a REST api. I can build the table fine with manually entered data, but when I try to insert a JSON array of data from the server the resulting table is empty.
Currently I have the following set up:
dataFactory.js - calls the API and gets a JSON response:
app.factory('dataFactory', ['$http', function($http) {
var urlBase = 'http://myurl.com/api';
var dataFactory = {};
dataFactory.getOrders = function() {
return $http.get(urlBase + '/orders');
};
return dataFactory;
}]);
My view is fairly basic and looks like this using to the Smart Table extension:
<div ng-controller="MainController">
<table st-table="ordersTable" class="table table-striped">
<thead>
<tr>
<th st-sort="createdBy">Name</th>
<th st-sort="id">ID</th>
<th st-sort="state">State</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="row in ordersTable">
<td>{{row.createdBy}}</td>
<td>{{row.id}}</td>
<td>{{row.state}}</td>
</tr>
</tbody>
</table>
</div>
And my MainController.js processes and stores the data, and builds the table:
app.controller('MainController', ['$scope', 'dataFactory', function($scope, dataFactory) {
$scope.status;
$scope.orders;
getOrders();
function getOrders() {
dataFactory.getOrders()
.success(function(ord) {
$scope.orders = ord;
})
.error(function(error) {
$scope.status = 'Unable to load order data: ' + error.message;
});
}
$scope.ordersTable = [
// If I build the data manually the table builds using the following 3 lines
//{createdBy: 'Laurent', id: '56433', state: 'Open')},
//{createdBy: 'Blandine', id: '34367', state: 'Open')},
//{createdBy: 'Francoise', id: '34566', state: 'Closed'}
//... however I actually want the data to come from the JSON array returned by my factory like this:
$scope.orders
];
}]);
What am I doing wrong? How can I get my data to show up in the table?
In the success callback you are updating $scope.orders and not $scope.orderTable. By the way use promise function then instead of success and error callback (extract from angularjs doc):
The $http legacy promise methods success and error have been deprecated. Use the standard then method instead. If $httpProvider.useLegacyPromiseExtensions is set to false then these methods will throw $http/legacy error.

In Angularjs, how to update table data after deleting a row from it

I am using the angularjs to call Asp.net Web API. After I delete a row from the table?
I also did not find the solution in w3schools.
My HTML code
<tr ng-repeat="user in users | filter: search">
<td>{{ user.Id }}</td>
<td>{{ user.FullName }}</td>
<td>{{ user.Mobile }}</td>
<td>{{ user.Birthdate }}</td>
<td>{{ user.Gender }}</td>
<td>{{ user.AcademicLevel }}</td>
<td>
My Angularjs code
$scope.DeleteUser = function (id) {
UserID = $scope.users[id].Id;
$http.delete('/api/users/' + UserID).success(function (data) {
(function (data) {
$scope.error = "error " + data;
});
}
I searched in Stackoverflow, I found some of these where they did not work for me, they confused me.
$scope.refresh()
$scope.apply();
First of all, handling server requests in your controller is a bad idea. As a rule of thumb, use services to delegate calls to the server, and use the controller for "gluing" up your models to your view.
There are a few issues in your code, it should look something like this:
$scope.DeleteUser = function (id) {
var userId = $scope.users[id].Id;
$http.delete('/api/users/' + userId)
.success(function (data) {
$scope.error = "error " + data;
});
}
Even if the call to the server was successful, you never updated your front-end model. What you have read on other topics regarding $scope.refresh(), I suppose that has the purpose of fetching the data again, like so:
$scope.refresh = function(){
$http.get('/api/users')
.success(function(data){
$scope.users = data;
});
}
So in order the refresh your view, you must update your model.
$scope.DeleteUser = function (id) {
var userId = $scope.users[id].Id;
$http.delete('/api/users/' + userId)
.success(function (data) {
//either this
$scope.refresh();
//or this
$scope.users.splice(id,1);
});
}
Two solutions : once you've performed your deletion, remove the user from the users array by doing a slice :
$scope.DeleteUser = function (index) {
var UserID = $scope.users[index].Id;
$http.delete('/api/users/' + UserID).then(function(del) {
$scope.users.splice(index,1);
});
}
You can get the index of the user by using $index in your ng-repeat but as your code may be asynchronous this is not recommended.
Or, you can just make another get from your API once your deletion is resolved.
$scope.DeleteUser = function (index) {
var UserID = $scope.users[index].Id;
$http.delete('/api/users/' + UserID).then(function(del) {
$http.get('/api/users').then(function(data){
$scope.users = data;
});
});
}
But... What if the person who's using your application is deleting users faster than your API is able to ?
First solution will fail for sure, and the second will hardly maintain you DOM clean as long as all requests came back in the same order they were sent.
One solution is to prevent any request to the API as long as another is already pending.
In JavaScript as Functions are in fact executable Objects they can have properties. So we'll add a isBusy property to the DeleteUser function to know when it is already processing.
$scope.DeleteUser = function (index) {
if(!$scope.DeleteUser.isBusy){
var UserID = $scope.users[id].Id;
$scope.DeleteUser.isBusy = true;
$http.delete('/api/users/' + UserID).then(function(del) {
$scope.users.splice(id,1);
$scope.DeleteUser.isBusy = false;
});
}
}
EDIT:
Update code to use .then() on $http promise object as .success() is now deprecated.
Just remove the user from the array:
// Find index of the user
var index = $scope.users.indexOf(id);
// Remove user from array
$scope.users.splice(index, 1);
Also, why are you fetching the user's id, when you already have it?:
$scope.DeleteUser = function (id) {
$http.delete('/api/users/' + id).success(function (data) {
var index = $scope.users.indexOf(id);
$scope.users.splice(index, 1);
});
}

Why can't I display data from Mongodb with Angular

and I am trying to display a collection called books in mongodb but for some reason I run into an ng-repeat dupes error. Also the data retrieved from my $http.get operation returns the HTML syntax of the entire page for some reason instead of accessing the data from the books collection. Thing is I created other programs prior to this where I had absolutely no problem with ng-repeat and they still work, the difference being the angular version is older. I am thinking that is the problem. If you have any insight on what I am doing wrong I would appreciate it. Thank you
Error:
Error: [ngRepeat:dupes]
http://errors.angularjs.org/1.3.14/ngRepeat/dupes?p0=book%20in%20library&p1=string%3A%3C&p2=%3C
Controller code:
var app = angular.module("myApp", []);
app.controller("bookCtrl", function($scope, $http) {
var refresh=function(){
$http.get('http://localhost:3000/storeHome').success(function(response){
console.log("I got the data I requested");
console.log(response); //returns HTML of the page instead of an object
$scope.library = response;
$scope.book="";
});
};
refresh();
});
Route code:
var express = require('express');
var router = express.Router();
var Book =require('../../models/book');
router.get('/', function(req, res) {
res.render('bookStore/storeHome');
});
//get all books from the database
router.get('/',function(req,res,next){
Book.find(function(err, books) {
if (err)
res.send(err);
console.log(books);
res.json(books);
});
});
Book model:
var mongoose = require('mongoose');
var BookSchema = new mongoose.Schema({
title: String,
author: String,
publisher: String,
year: Number
});
module.exports=mongoose.model('Book', BookSchema);
HTML
<div class="container" ng-app="myApp" ng-controller="bookCtrl">
<table class="table">
<!--omitted code in between -->
<tr ng-repeat="book in library"> <!-- I tried track by $index and it didn't work-->
<td>{{book.title}} </td>
</tr>
</div>
I think the nodejs response is wrong. The res.json...try another options please.
EDIT: LIke this: res.status(200).send({myBooksList:list})
or this: res.send(200,{myBooksList:list})
Im still not sure :D, sorry.
Change your template's ng-repeat to :
<tr ng-repeat="book in library track by $index">
It doesn't handle duplicate data very well as it tries to find an identifier that is unique for every item. But since there's duplicates in the data angular is unable to do so... We can use the assigned repeat index to track the item by.
This might work:
Book.find(function(err, books) {
if (err)
res.send(err);
res.end(JSON.stringify(books));
}
}));
