I have been working on a todo application, and I am facing an issue with the ng-repeat directive in my code. It seems to create five todo boxes even when the database is empty. This may be related to the loadData function that I am calling, but I am unable to pinpoint the exact cause. You can view a screenshot of how it appears in my browser along with debugger data here. Upon making a GET request to localhost:3000/api/todos, I receive [], indicating that the database is indeed empty. Any suggestions or insights?
Here is a snippet from my html file:
<div class="row">
<h1>Things you have to do</h1>
<li ng-repeat="todo in todos">
<p id="todobox"> {{ todo.name }} </p>
</li>
<form>
<input type="text" placeholder="I need to do..." ng-model="formData.newTodo" required>
<button ng-click="addTodo(formData)">Add</button>
</form>
</div>
This is my controller:
var app = angular.module('myApp', ['navigationDirective']);
app.controller('MainController', ['$scope','$http', function($scope, $http){
$scope.formData = {};
$scope.loadData = function(){
$http.get('/api/todos')
.then(function(data){
console.log('Data:' + data);
$scope.todos = data;
});
};
//call the loadData function that returns the data from the json file
$scope.loadData();
//Add a new todo to the database
$scope.addTodo = function(){
$scope.formData = {
name: $scope.formData.newTodo
};
$http.post('/api/todos', $scope.formData)
.then(function(data){
console.log($scope.formData.name);
$scope.todos = data;
$scope.formData = {};
console.log(data);
});
}
}]);
and here is my server.js file:
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var mongoose = require('mongoose');
//connect to database
mongoose.connect('mongodb://localhost:27017/tododbtest');
// set static files location
// used for requests that our frontend will make
app.use(express.static(__dirname + '/public'));
//app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
//define our model for the todos
var Todo = mongoose.model('Todo', {
name: String,
//maybe change it to bool later
//checked: boolean
});
//when I get a get request I'm going to send
//the index.html file
app.get('/', function(req, res){
res.sendFile( __dirname + '/public/index.html');
});
//get all the todos from the database
app.get('/api/todos', function(req, res){
Todo.find(function(err, todos){
if(err)
res.send(err)
console.log(todos);
res.json(todos);
});
});
//create a todo
app.post('/api/todos', function(req, res){
console.log("Req.body.name:" + req.body.name);
Todo.create({name: req.body.name, checked: false},
function(err, todo){
if(err) res.send(err);
Todo.find(function(err, todos){
if(err) res.send(err);
res.json(todos);
});
});
});
app.listen(3000);
