How can Angular 4 manage an object containing other objects most effectively?

Who can guide me on the best way to handle a data structure like this:

 {  
      "1":{  
         "id":"1",
         "name":"Facebook",
         "created_at":"",
         "updated_at":"",
         "fields":{  
            "1":{  
               "id":"1",
               "name":"G\u00f6rsel",
               "service_id":"1",
               "ord":"1",
               "token":"fimage",
               "type":"1",
               "created_at":null,
               "updated_at":null
            },
            "2":{  
               "id":"2",
               "name":"Post Metini",
               "service_id":"1",
               "ord":"2",
               "token":"ftext",
               "type":"2",
               "created_at":null,
               "updated_at":null
            },
            "3":{  
               "id":"3",
               "name":"Ba\u015fl\u0131k",
               "service_id":"1",
               "ord":"3",
               "token":"fheader",
               "type":"2",
               "created_at":null,
               "updated_at":null
            },
            "4":{  
               "id":"4",
               "name":"Link A\u00e7\u0131klamas\u0131",
               "service_id":"1",
               "ord":"4",
               "token":"flink_description",
               "type":"2",
               "created_at":null,
               "updated_at":null
            }
         }
      },
      "2":{  },
      "3":{  }
}

I have observed that Angular functions such as sorting, filtering, and looping through data are based on javascript arrays. What is the recommended method of handling similar structures in Angular 4 for functionalities like *ngFor, filters, etc.? When attempting to iterate over this object with NgFor, I encounter:

Error: Cannot find a differ supporting object '[object Object]' of type 'object'. NgFor only supports binding to Iterables such as Arrays.

At this point, I am uncertain about the best course of action. I could convert the object to an array, but is that the optimal approach?

Answer №1

Enhancing the organization of the structure would be beneficial. Utilizing an array of objects within the "fields" section could provide more efficiency as it allows for easy looping through the array.

Answer №2

After seeking advice from @ThomasSablik on a similar issue, I decided to use Pipes to handle it. His recommendation led me to the perfect solution that met my needs. Currently, I am utilizing the following pipe which is performing exceptionally well:

export class KeyValuesPipe implements PipeTransform {
  transform(value, args:string[]) : any {
    let keys = [];
    for (let key in value) {
      keys.push({key: key, value: value[key]});
    }
    return keys;
  }
}

I am grateful to Thomas for guiding me in the right direction.
