What is the best way to assign a value to a key-value property in Angular?

Consider the scenario where I have the given object:

export interface File {
  id: string;
  displayname: string;
  filesize: number;
  isarchived: boolean;
  userId: string;
  [key: string]: any;
}

and the following method:

export class BasketService {
    addFile(file: File ) { //Some code here }
}

Now, when I invoke my method like this:

this._basketService.addFile({
  id: file.id,
  displayname: file.originalEntry['displayname'],
  filesize: file.originalEntry['filesize'],
  isarchived: file.originalEntry['isarchived'],
  userId: this._appSession.user.id,
  ???: file.originalEntry // <=== How can I set the key value pair here?
});

The object:

file.originalEntry is [key: string]
. Instead of passing individual key/value pairs, I want to pass the entire object.

Answer №1

Take a shot at it in this way:

this._basketService.addFile({
  id: file.id,
  displayname: file.originalEntry['displayname'],
  filesize: file.originalEntry['filesize'],
  isarchived: file.originalEntry['isarchived'],
  userId: this._appSession.user.id,
  keyValue: {key:file.id, value: file.originalEntry}
});

Answer №2

When the declaration appears as follows:

public dictionary: { [key: string]: string } = {};

You can assign a value to it using this method:

this.dictionary = { ID: key, Value: defaultValue }; // where key and defaultValue are variables

In your scenario, provide the following:

{ ID: key, Value: defaultValue }

Answer №3

To successfully tackle this issue, I specifically defined the key/value pairs needed for my object as shown below:

const digitalObject = {
        id: file.id,
        displayname: file.originalEntry['displayname'],
        filesize: file.originalEntry['filesize'],
        isarchived: file.originalEntry['isarchived'],
        userId: this._appSession.user.id,
        code: file.originalEntry['code'],
        needle: file.originalEntry['needle'],
        x8: file.originalEntry['x8'][0],
        x5: file.originalEntry['x5'][0],
        8: file.originalEntry['8'][0],
        5: file.originalEntry['5'][0],
        creationtime: file.creationTime
    };

    this._basketService.addFile(digitalObject);

I appreciate all the helpful contributions that led to resolving this issue.
