I am trying to get two way binding to work with Angular/ionic and I have the following for my component html:
<ion-card>
<ion-card-header>
<ion-button><</ion-button>
<ion-card-title>Create course</ion-card-title>
<ion-button (click)=createYogaClass()>Create</ion-button>
</ion-card-header>
<ion-card-content>
<ion-list>
<ion-item>
<ion-label>Name course</ion-label>
<ion-input [(ngModel)]='randomString'>{{randomString}}</ion-input>
</ion-item>
<ion-item>
<ion-label>Location</ion-label>
<ion-input type="text"></ion-input>
</ion-item>
<ion-item>
<ion-label>Date</ion-label>
<ion-input type="date"></ion-input>
</ion-item>
<ion-item>
<ion-label>Start time</ion-label>
<ion-input type="time"></ion-input>
</ion-item>
<ion-item>
<ion-label>End time</ion-label>
<ion-input type="time"></ion-input>
</ion-item>
<ion-item>
<ion-label>Course description</ion-label>
<ion-textarea type="text"></ion-textarea>
</ion-item>
<ion-item>
<ion-label>Teacher</ion-label>
<ion-input type="text"></ion-input>
</ion-item>
<ion-item>
<ion-label>Teacher's description</ion-label>
<ion-textarea type="text"></ion-textarea>
</ion-item>
<ion-item>
<ion-label>Available seats</ion-label>
<ion-input type="number"></ion-input>
</ion-item>
</ion-list>
</ion-card-content>
</ion-card>
And this for my component .ts file:
import { Component, OnInit } from '@angular/core';
@Component({
selector: 'app-create',
templateUrl: './create.component.html',
styleUrls: ['./create.component.scss'],
})
export class CreateComponent implements OnInit {
randomString: string = 'randomString';
constructor() { }
createYogaClass(){
console.log("Creating yogaclass!");
console.log(this.randomString);
}
ngOnInit() {}
}
However whenever I try to change the value through the input changed the 'randomString' remains undefined... Can you help me figure out what the issue is. Just for clarification my app.module.ts file:
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { RouteReuseStrategy } from '@angular/router';
import { HttpClientModule } from '@angular/common/http';
import { FormsModule } from '@angular/forms';
import { IonicModule, IonicRouteStrategy } from '@ionic/angular';
import { AppComponent } from './app.component';
import { AppRoutingModule } from './app-routing.module';
import { RegisterComponent } from './register/register.component';
@NgModule({
declarations: [AppComponent, RegisterComponent],
entryComponents: [],
imports: [BrowserModule, IonicModule.forRoot(), AppRoutingModule, HttpClientModule, FormsModule],
providers: [{ provide: RouteReuseStrategy, useClass: IonicRouteStrategy, }],
bootstrap: [AppComponent],
})
export class AppModule {}
the current result after pressing create button: https://imgur.com/a/j7tLLVg

I figured it out I forget to add my CreateComponent to the declarations like so:
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { RouteReuseStrategy } from '@angular/router';
import { HttpClientModule } from '@angular/common/http';
import { FormsModule } from '@angular/forms';
import { IonicModule, IonicRouteStrategy } from '@ionic/angular';
import { AppComponent } from './app.component';
import { AppRoutingModule } from './app-routing.module';
import { RegisterComponent } from './register/register.component';
import { CreateComponent } from './create/create.component';
@NgModule({
declarations: [AppComponent, RegisterComponent, CreateComponent],
entryComponents: [],
imports: [BrowserModule, IonicModule.forRoot(), AppRoutingModule, HttpClientModule, FormsModule],
providers: [{ provide: RouteReuseStrategy, useClass: IonicRouteStrategy, }],
bootstrap: [AppComponent],
})
export class AppModule {}
