In Angular 11, I noticed that the data with the key 'id' is highlighted in red in this particular section. Is there a way to change this visual formatting?

My goal is to access the id within the form input, and once added, I want to display the details of the added record.

  add(city:City)
  {

    this.httpClient.post(this.path+'cities/add',city).subscribe(data=>{
      this.alertifyService.success("Şehir Başarayla Eklendi.");
      this.router.navigateByUrl('cityDetail/'+data['id']);
    });
  }

Answer №1

Implement a new feature for adding city information

addCity(city: City) {
  this.httpClient.post<{ id: string }>(this.path+'cities/add', city).subscribe(data => {
    this.alertifyService.success("City successfully added.");
    this.router.navigateByUrl('cityDetail/' + data['id']);
  });
}

Answer №2

You are not fully utilizing the capabilities of typescript in this scenario, which is why you are encountering difficulty accessing the id property. It's important to define the type of arguments, responses, invocations, and returns whenever possible.

In your specific situation, you neglected to specify how angular should handle the response from this post request. Essentially, you need to determine what type of data will be received. To address this, consider using a typescript type assertion, like so:

Keep in mind that the properties and types I included in the post request are just examples.

this.httpClient.post<{
    prop1: string;
    prop2: boolean;
    id: number
}>(this.path + 'cities/add', city)
