  selector: 'form-date-simple',
  template: ` <sf [schema]="schema" (formSubmit)="submit($event)" (formChange)="change($event)"></sf> `,
})
export class FormDateSimpleComponent {
  schema: SFSchema = {
    properties: {
      datetime: {
        type: 'string',
        format: 'date-time',
      },
      date: {
        type: 'string',
        format: 'date',
      },
      date_number: {
        type: 'number',
        ui: { widget: 'date' } as SFDateWidgetSchema,
      },
      year: {
        type: 'number',
        ui: { widget: 'date', mode: 'year', format: 'yyyy' } as SFDateWidgetSchema,
      },
      month: {

        format: 'month',
      },
      week: {
        type: 'string',

  constructor(private msg: NzMessageService) {}

  submit(value: {}): void {
    this.msg.success(JSON.stringify(value));
  }

  change(value: {}): void {
