In Part-I we have done how to use basic AngularJs in our Ruby on Rails Project.

Now today we will work with the controller and model in angularJs and submit that book form and add that book into the list.Lets proceed further:

Step 1: Now we will define a controller into our view (index.html.erb) using a div using ‘ng-controller’ like:

Step 2: Now we will define the controller in the welcome.js file

Here ‘myapp’ is same as we have defined in application.html.erb within ‘ng-app’ and ‘welcomeCtrl’ is same which we have defined in view index.html.erb.

$scope is an object by which we will use to interact with the view, we can get and set variables and functions on it.

Here we have set a books array with hashes as the elements.

Step 3: Now first of all we have to access this books array on our view and show a list of books . So come to the index.html.erb and add a list like:

Here ‘ng-repeat’ will works like as loop and return every book one by one that are available in books array.

Now Refresh the browser and you will see a list of available books.

Step 4: Now we have to submit this form and add the value to the list shown below.

For this we have to add  ng-submit=”addEntry()” in our form tag. Basically ‘ng-submit’ will call the ‘addEntry()’ method when this form will submit. Like,

Step 5: Now we have to define this ‘addEntry()’ method in our Angular controller that we have defined in welcome.js file

Here $scope.books.push($scope.newEntry) will push the newEntry object in books array. ‘newEntry’ is that object which will use to access the form fields as we have described in Part-I blog.

And after pushing the newEntry data into books array we have to reset the fields so we will initialize ‘newEntry’ with null {}

Now All Done, refresh and add some book.
