Requesting data in Angular using the get method

Question

Requesting data in Angular using the get method

I currently have an operational angular form embedded within a rails app. It successfully sends a get request to the rails server.

However, I am facing an issue where if the app receives a normal get request, the page refreshes. But when the request is sent through angular, although it reaches the server, the page does not refresh (even though I can retrieve data using these get requests).

My query is regarding how to pass a get request in an angular form so that the server can process it as usual and trigger a page refresh.

The HTML code snippet:

<form ng-submit="submitForm()" style="margin-top:30px;">
  <h3>get request</h3>
  <button type="submit" class="btn btn-primary">Get</button>
</form>

The controller code in app.js:

$scope.submitForm = function(){
  posts.factorySubmit();
};

The factory get function in app.js:

o.factorySubmit = function() { 
      $http.get('http://localhost:8080/clients');
};

--Side note - Interestingly, creating a get request with regular JavaScript in the app (outside of the angular context) results in the expected behavior of page refreshing.

You have wisely encapsulated your $http call within a factory, showcasing good coding practice. However, one important aspect you are missing is capturing the response from the call.

o.factorySubmit = function() {
      // Don't forget to include a return statement here
      return $http.get('http://localhost:8080/clients'); // This method returns a promise
};

Subsequently, when you invoke this function...

$scope.submitForm = function(){
  posts.factorySubmit().then(function(response) {
    $scope.requests = response.data;  // This is where you can access your response data
  },
  function(response) {
    // Handle any errors here
  });
};

An interesting feature of Angular is its ability to automatically update the page in response to changes. It incorporates a digest cycle internally that triggers updates. By using the built-in $http provider, the page will be refreshed whenever you modify the $scope variables.

Angular is specifically designed to cater to Single Page Applications without the need for page refreshes. If you do wish to manually refresh the page, you can achieve this by using:

$scope.submitForm = function(){
  posts.factorySubmit().success(function(){
   $route.refresh();
  });
};

You should include the above code in the success function of your $get request, and don't forget to inject $route into your controller.
