Troubleshoot: Issue with injecting external component into another component using directive in Angular 2

I need the child component template to be loaded into the parent component template. (calling them child and parent for simplicity)

Here is the child component:

import {Component,Directive, ElementRef, Input} from '@angular/core';
import {IONIC_DIRECTIVES} from 'ionic-angular';


@Component({ 
  selector: '[parentselector]',
  template: '<div>I AM A CHILD</div>',
  directives: [IONIC_DIRECTIVES] 
})


export class ChildPage {
    constructor() {

    }
}

This is my parent component:

@Component({
    templateUrl: 'build/pages/parent/parent.html',
    directives: [ChildPage]
})

And here is the HTML of the Parent Component:

<ion-content>
    <ion-slides>
        <ion-slide><parentselector>Parent To Be Overridden</parentselector>
        </ion-slide>
    </ion-slides>
</ion-content>

Can you spot any issues in this setup?

Answer №1

According to the information provided in the Angular 2 Cheat Sheet (refer to the selector section), brackets are used to restrict where a directive can be applied. For instance:

selector:'[parentselector]' - indicates attribute selection only
selector:'parentselector' - specifies element selection only
selector:'.parentselector' - allows CSS class selection only

Therefore, removing the [] should resolve any issues.
