I have an app I’m re-developing in ionic which I did in ionic-v1 a year or so ago. I have multiple template types which a user will pick from and I would like to make a dynamic component which loads its templateURL based off the user configuration value. So everything is working as far as loading the component and getting the right template except when I go to run the app, it gives template errors as though it doesn’t know ngModel is an angular attribute.
Here’s what I have:
import { Compiler, Component, AfterViewInit, OnInit, Injector, ViewChild, NgModule, NgModuleRef, ViewContainerRef } from '@angular/core';
import { NavController } from 'ionic-angular';
import { ImageSliderComponent } from '../../app/components/image-slider/image-slider';
import { SomeService } from '../../app/services/app.services';
@Component({
template: `<ng-container #dynamicvc></ng-container>`
})
export class DynamicHome implements OnInit {
@ViewChild('dynamicvc', { read: ViewContainerRef }) container;
ehi: any;
sponsorGroups: any[];
baseUrl: string;
selectedSegment: string;
constructor(private compiler: Compiler, private injector: Injector, private moduleRef: NgModuleRef<any>, private someSvc: SomeService, private navCtrl: NavController) {
let vm = this;
vm.selectedSegment = 'home';
}
ngAfterViewInit() {
let vm = this;
const MaterialCardsSpookyHomeComponent = Component({
templateUrl: './materialcardsspooky/materialcardsspooky-home.html'
})(class MaterialCardsSpookyHomeComponent { });
const MaterialCardsSpookyHomeModule = NgModule({
declarations: [
MaterialCardsSpookyHomeComponent,
ImageSliderComponent
],
imports: [
IonicPageModule.forChild(MaterialCardsSpookyHomeComponent)
]
})(class MaterialCardsSpookyHomeModule { });
let moduleToUse = null;
switch (vm.someSvc.template.toLowerCase()) {
case 'materialcardsspooky':
moduleToUse = MaterialCardsSpookyHomeModule;
break;
}
if (moduleToUse) {
vm.compiler.compileModuleAndAllComponentsAsync(moduleToUse).then((factories) => {
const f = factories.componentFactories[0];
const cmpRef = f.create(vm.injector, [], null, vm.moduleRef);
cmpRef.instance.ehi = vm.ehi;
cmpRef.instance.sponsorGroups = vm.sponsorGroups;
cmpRef.instance.baseUrl = vm.baseUrl;
cmpRef.instance.selectedSegment = vm.selectedSegment;
vm.container.insert(cmpRef.hostView);
});
}
}
ngOnInit() {
let vm = this;
}
}
Here’s my template:
<ion-header>
<ion-toolbar no-border-top no-border-bottom>
<ion-segment [(ngModel)]="selectedSegment">
<ion-segment-button value="home" no-border-bottom>
<ion-icon name="home"></ion-icon>
</ion-segment-button>
</ion-segment>
</ion-toolbar>
</ion-header>
<ion-content>
<div [ngSwitch]="selectedSegment">
<div *ngSwitchCase="'home'">
<image-slider [slides]="ehi?.images" [imagetype]="2"></image-slider>
...
</div>
</div>
</ion-content>
Here’s my custom component:
import { Component, OnInit, Input, ViewChild } from '@angular/core';
import { Slides } from 'ionic-angular';
@Component({
selector: 'image-slider',
templateUrl: 'image-slider.html'
})
export class ImageSliderComponent implements OnInit {
@Input() slides: any[];
@Input() imagetype: string;
imageSlides: any[] = [];
@ViewChild(Slides) imgSlides: Slides;
constructor() { }
ngOnInit() {
let vm = this;
vm.slides.forEach((s) => {
if (s.imageType === vm.imagetype.toString()) {
if (s.imageUrl.indexOf(vm.ehmSvc.baseUrl) != 0) {
s.imageUrl = vm.ehmSvc.baseUrl + s.imageUrl;
}
vm.imageSlides.push(s);
}
});
//[pager]="true" [loop]="true" [effect]="fade" [centeredSlides]="true" [spaceBetween]="10"
if (vm.imageSlides.length === 1) {
vm.imgSlides.pager = false;
} else {
vm.imgSlides.pager = true;
}
vm.imgSlides.autoHeight = true;
}
}
And here are my errors in Chrome Dev Tools:
Can’t bind to ‘slides’ since it isn’t a known property of ‘image-slider’.
- If ‘image-slider’ is an Angular component and it has ‘slides’ input, then verify that it is part of this module.
- If ‘image-slider’ is a Web Component then add ‘CUSTOM_ELEMENTS_SCHEMA’ to the ‘@NgModule.schemas’ of this component
to suppress this message.- To allow any property add ‘NO_ERRORS_SCHEMA’ to the ‘@NgModule.schemas’ of this component. ("
Any ideas how or even if I can accomplish this? Also, using VS2017 and standard Ionic template with default build scripts, i.e. webpack.
