4 min readIn Ember.js, XHR calls should typically be kept in the route's model hook or in a service. The model hook of a route is where you can fetch data from an API using XHR calls and set it as the model for that route, which will automatically be rendered in the template. Alternatively, you can create a service to handle all of your XHR calls. Services are reusable across different parts of your application and can provide a centralized place to manage and make XHR requests.

5 min readIn Ember.js, when creating a child record and you need to get its parent ID, you can do so by maintaining a reference to the parent record. This can be achieved by either passing the parent record as a parameter when creating the child record, or setting the parent record on the child record after it has been created.For example, if you have a parentModel and a childModel with a belongsTo relationship, you can create a new child record like this: let parentRecord = this.get('store').

5 min readIn Ember.js, bindings are used to create data bindings between properties of different objects. To set up bindings in Ember.js, you can declare them in two ways:In the template file using the {{bind}} helper, you can specify the paths of the properties you want to bind to. For example, {{bind someProperty}} will create a one-way binding from the current object's someProperty to the property of the same name in the target object.

5 min readTo modularize Ember.js templates, you can break them down into smaller, reusable components. This can be achieved by creating individual template files for each component and then including these components in the main template file. By doing this, you can create a more organized and maintainable codebase.Another approach is to use Ember's built-in template helper functions, such as {{partial}} or {{render}}, to include partial templates within your main template.

6 min readTo re-render a template using a cached property in Ember.js, you can make use of the @cached decorator. This decorator is used to create a property that returns a cached value, which will only be re-calculated if one of its dependencies changes.To implement this, you can define a cached property in your Ember component or controller using the @cached decorator on a getter method. This cached property can then be used in your template to display the cached value.

5 min readIn Ember.js, handling HTTP request failures can be done by utilizing Ember's built-in error handling mechanisms.One approach is to use the catch method on the promise object returned by the ajax or $.ajax methods to handle any errors that occur during the HTTP request. This allows you to define a callback function that will be called if the request fails.Another method is to use the didError hook on the model or route object to handle errors that occur during the request.

4 min readOne-way binding in Ember.js allows you to pass data from a parent component down to a child component without allowing the child component to modify the data. This is useful when you want to maintain a single source of truth for data across multiple components.To use one-way binding in Ember.js, you can use the @ symbol in your component template to indicate that the data being passed is read-only.

6 min readIn Ember.js, views can be inherited by creating a new view that extends an existing one. This allows you to reuse common functionality and properties across different views in your application. To inherit a view in Ember.js, you would typically create a new view using the extend() method and reference the parent view as the base. You can then add or override any specific functionality or properties as needed in the child view.

6 min readTo run Ember.js on localhost, you first need to have Node.js and npm installed on your system.Once you have Node.js and npm installed, you can create a new Ember.js project by running the following command in your terminal: npm install -g ember-cli After that, you can navigate to the directory where you want to create your Ember.js project and run the following command: ember new my-ember-project This will create a new Ember.js project in a folder called my-ember-project.

6 min readIn Ember.js, you can catch global keypress events by adding event listeners to the window or document objects. This allows you to listen for keypress events anywhere in your Ember application, not just within specific components or routes.To catch global keypress events, you can create a service or mixin that adds event listeners to the window or document objects.

6 min readIn Ember.js, you can add or remove a class to an array of objects by iterating through the array and updating each object individually. You can do this by using the set method to update the class attribute of each object in the array.For example, if you have an array of objects called items and you want to add a class called new-class to each object in the array, you can do so by using the following code: items.forEach(item => { item.
