If I have an array of JSON objects, how can I cast or assign the Report class to it?
console.log('jsonBody ' + jsonBody);
// Output: jsonBody [object Object],[object Object]
console.log('jsonBody ' + JSON.stringify(jsonBody));
// Output: jsonBody [{"created_at":"2016-02-04","updated_at":"2016-02-04 00:45:56.000"}, {"created_at":"2016-02-04","updated_at":"2016-02-04 00:45:56.000"}]
// TypeScript class
export class Report {
created_at!: Date;
updated_at!: Date;
}
Develop a constructor that can handle JSON object parameters:
class ReportData {
dateCreated!: Date;
dateUpdated!: Date;
constructor({dateCreated, dateUpdated}: {dateCreated: string, dateUpdated: string}) {
this.dateCreated = new Date(dateCreated);
this.dateUpdated = new Date(dateUpdated);
}
}
let jsonData = [{"dateCreated":"2016-02-04","dateUpdated":"2016-02-04 00:45:56.000"}, {"dateCreated":"2016-02-04","dateUpdated":"2016-02-04 00:45:56.000"}];
let dataArray: ReportData[] = jsonData.map(obj => new ReportData(obj));
