Angular error: "Can't bind to 'ngModel' since it isn't a known property of 'input'"
In order to use two-way data binding for form inputs you need to import the FormsModule
package in your Angular module.
import { FormsModule } from '@angular/forms';
@NgModule({
imports: [
FormsModule
]
EDIT
Since there are lot of duplicate questions with the same problem, I am enhancing this answer.
There are two possible reasons
Missing
FormsModule
, hence Add this to your Module,import { FormsModule } from '@angular/forms'; @NgModule({ imports: [ FormsModule ]
Check the syntax/spelling of
[(ngModel)]
in the input tag
This is a right answer. you need to import FormsMoudle
first in app.module.ts
**
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { NgModule } from '@angular/core';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
FormsModule,
ReactiveFormsModule ,
BrowserModule,
AppRoutingModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
** second in app.component.spec.ts
import { TestBed, async } from '@angular/core/testing';
import { RouterTestingModule } from '@angular/router/testing';
import { AppComponent } from './app.component';
import { FormsModule } from '@angular/forms';
describe('AppComponent', () => {
beforeEach(async(() => {
TestBed.configureTestingModule({
imports: [
RouterTestingModule,
FormsModule
],
declarations: [
AppComponent
],
}).compileComponents();
}));
Best regards and hope will be helpfull
Your ngModel
is not working because it's not a part of your NgModule
yet.
You have to tell the NgModule
that you have authority to use ngModel
throughout your app, You can do it by adding FormsModule
into your app.module.ts
-> imports
-> []
.
import { FormsModule } from '@angular/forms';
@NgModule({
imports: [ FormsModule ], // HERE
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
