How to create buttons in a user interface to manage data?

If you are looking to improve the user experience by allowing them to manage data effectively, the use of interactive buttons is essential. Any modern application should facilitate direct interaction to update and create data without relying on tools like Postman. Here we will cover how to implement buttons in an application using IONIC and Typescript.

What buttons do we need?

To manage our data wheels, we will create two crucial buttons:

1. Refresh data button: This button will allow the user to refresh the list of wheels, reflecting recent changes.
2. Create new wheel button: When clicked, the user will be directed to a screen to enter details of a new wheel.

How to add the buttons in IONIC?

First, let's add the necessary tags in the code corresponding to the Toolbar. For this, we follow the steps:

<ion-buttons slot="start"> <ion-button (click)="getRaids()"> <ion-icon slot="start" name="refresh"></ion-icon> </ion-button></ion-buttons></ion-buttons>.

Here, getRaids() is a method that we will define to get the wheels information. Next, we prepare the following button, which will redirect to a new page to create wheels.

<ion-buttons slot="end"> <ion-button routerLink="/create-raide"> <ion-icon slot="end" name="add"></ion-icon> </ion-button></ion-buttons></ion-buttons>

How to implement the GetRaids method?

This method is fundamental. Its main task is to call the API to get the updated wheel information.

function getRaids() { // we call the API to get the wheels this.raidService.getRaids().subscribe((raids) => { this.raids = raids; });} }

What role do dynamic routes play in the creation screen?

Flexibility in routes is key to reusing components, allowing the user to create or edit wheels via a URI parameter.

const routes: Routes = [ { { path: 'create-raide/:id', component: RaideFormPage }, { path: 'create-raide', component: RaideFormPage }];

How to inject the ActiveRoute to handle parameters?

The ActiveRoute is crucial to extract parameters from the URL, allowing differentiated behaviors depending on the user action (create vs edit):

 {import { ActivatedRoute } from '@angular/router';
@Component({ // ...})export class RaideFormPage implements OnInit { constructor(private route: ActivatedRoute) {}
 ngOnInit() { this.route.params.subscribe(params => { const id = params['id']; if (id) { this.loadRaide(id); // Method for loading data from the specific wheel } } );} }}

What's next after the buttons and routes?

Now that our buttons are ready and the routes are working correctly, the next step is to implement the form that will allow us to enter the details of the wheels. This will be done in a new class that will focus on building a form using Angular forms to collect and validate the data before it is submitted.
