Using ng-template in child component from Parent Component in Angular

I am facing a situation where I have a BaseComponent and IncomingRequestsComponent that inherit from BaseComponent. To utilize templates in components that inherit from BaseComponent, I need to include them in the HTML of BaseComponent.

export class BaseTimeComponent implements OnInit, OnDestroy, AfterViewInit {
// some code
}

<ng-template #selectField let-field="fieldName" let-record="recordId">
{{fieldName}} - {{record}}
</ng-template>

For IncomingRequests:

export class IncomingRequestsComponent extends BaseComponent implements OnInit {
// some code
}

<ng-container *ngIf="field.DataType == 3">
  <ng-container
   [ngTemplateOutlet]="selectTemplate"
   [ngTemplateOutletContext]="{ fieldName: fieldName, recordId: recordId}"
  ></ng-container>
</ng-container>

Despite the absence of errors, the template is not getting passed to the IncomingRequestsComponent. Is there an alternative approach to achieve this goal?

Answer №1

Decorators are often used to modify a class, however, they do not impact the class that extends the base class (check out this example where the decorator should be called thrice, not twice).

As a result, you cannot simply provide a "base HTML file" to your child classes.

If you wish to reference a template from a component, you must create an instance of the component and its children, utilizing Angular to facilitate data sharing between them.
