TypeScript と BackboneJS を使用してテスト アプリケーションに取り組んでいます。主に従業員名簿です。コレクションを定義しようとすると、次のエラーが発生します。
Type of overridden member 'url' is not subtype of original member defined by type 'Collection'
これが私のモデルとコレクションの定義です。
class Employee extends Backbone.Model {
reports: EmployeeCollection;
constructor (options? ) {
super(options);
this.reports = new EmployeeCollection();
this.reports.url = '../api/employees/' + this.id + '/reports';
}
}
class EmployeeCollection extends Backbone.Collection {
url: string = "../api/employees";
model = Employee;
findByName(key) {}
}
Backbone と TypeScript を接続するためのいくつかの定義も使用しています。使用しているファイルは次のとおりです。
export class Model {
static extend(properties: any, classProperties?: any): any; // do not use, prefer TypeScript's extend functionality
constructor (attributes?: any, options?: any);
