Utilize ng-model to incorporate an object

Question

Utilize ng-model to incorporate an object

I am faced with a challenge when it comes to updating values in a form upon submission. The current setup looks like this:

<form ng-submit="updateMovie()">
    <input type="text" ng-model="movie.title"/>
    <input type="text" ng-model="movie.rating"/>

    //what should be added here for ng-model//
    <input type="text" ng-modal ="movie.__"/>
   there may be multiple genre inputs depending on user input

</form>

The data structure submitted by the form will resemble the following format, without considering the ids at this point. I am uncertain about how to deal with creating the genre data, which is an array of objects.

"id": 4792,
"title": "Insidious",
"rating": "7.0",
"genres": [
  {
    "id": 3,
    "name": "horror"
  },
  {
    "id": 7,
    "name": "Drama"
  }
]

To update the list of genres in a movie object in AngularJS, you can create an input field where users can type in a genre and then click a button to add it to the list.

Here is an example implementation:

angular.module("app", [])

.controller('mainCtrl', function($scope) {
  $scope.movie = {};

  $scope.movie.genres = [];
  $scope.add = function() {
    if ($scope.genre) {
      $scope.movie.genres.push($scope.genre);
      $scope.genre = '';
    }
  }
});

<html ng-app="app">

<head>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.7/angular.min.js"></script>

<body ng-controller="mainCtrl">
  <form ng-submit="updateMovie()">
    <label for="title">Title: </label>
    <input type="text" id="title" ng-model="movie.title">
    <br>
    <label for="rating">Rating: </label>
    <input type="text" id="rating" ng-model="movie.rating">
    <br>
    <label for="genre">Genre: </label>
    <input type="text" id="genre" ng-model="genre">
    <button type="button" ng-click="add()">Add genre</button>
  </form>
</body>

To begin with, there is a fundamental flaw in your design strategy as you are attempting to allow the user to input any type of data and then match it against a predefined set of information which may be random. I would suggest considering using alternative methods such as multi-select dropdowns or checkboxes. An auto-suggestion feature that confines the user to a predetermined list of genres could also greatly enhance the user experience.

If you still wish to proceed with this approach, there are steps you can take to improve the process.

Separate the ng-model for the entered genre(s) from the form data. This means that in the updateMovie() function, you will need to manipulate the data appropriately.

Allow the user to associate a genre with a simple string:

<input type="text" ng-model ="movie.userGenres"/>

In the updateMovie() method, parse the data based on spaces, commas, etc., and map it to your genres array if feasible. Subsequently, transmit the mapped data instead of the raw inputted string provided by the user.

If you're looking to enhance your tagging system, consider using ngTagInput.

var application = angular.module('application', []);

application.controller('yourController', function() {
    $scope.film = {
      title: '',
      summary: '',
      categories: [],
    };
});


<tags-input id="categories" class="input-border" ng-model="film.categories"
                            placeholder="Categories for film"
                            add-on-comma="true"
                            replace-spaces-with-dashes="false"
                            on-tag-added="$tag.text=$tag.text.toLowerCase()"></tags-input>

To customize the format of genres, convert them into an array like this:

[{text: 'genre1'}, {text: 'genre2'}]
