Angular Can't bind to 'ngModel' With FormsModule already imported

Question

Note : I'm not a front end dev, even if I do a bit of it. If anything you see can be improved, do not hesitate to share ;)

Strange behavior here, I can't find out why. I have the famous "Can't bind to 'ngModel' since it isn't a known property of 'input'." in the console. But "FormsModule" is imported in the corresponding @Module, which contains the component on the declarations array. So I can't find a solutions on the already answered questions (or if you find, tell me how ;) ). The module :

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { FormsModule } from '@angular/forms';
import { TranslateModule } from '@ngx-translate/core';


import { UserPreferencesComponent } from './user-preferences/user-preferences.component';


@NgModule({
  declarations: [
    UserPreferencesComponent
  ],
  imports: [
    CommonModule,
    FormsModule,
    TranslateModule
  ]
})
export class UserPreferencesModule { }

The component

import { Component, OnInit } from '@angular/core';
import { TranslateService } from '@ngx-translate/core';
import { UserPreferences } from '../../entities/UserPreferences';
import { UserPreferencesService } from '../../services/user-preferences.service';

@Component({
  selector: 'acm-user-preferences',
  templateUrl: './user-preferences.component.html',
  styleUrls: ['./user-preferences.component.scss']
})
export class UserPreferencesComponent implements OnInit {
  public userPrefs: UserPreferences;
  public foo: number;

  constructor(private translateService: TranslateService, private userPreferencesService: UserPreferencesService) { }

  public ngOnInit(): void {
    this.userPreferencesService.getUserPreferences('default').subscribe(userPref => {
      this.userPrefs = userPref;
    });
  }
}

The html template

<h1>Preferences</h1>>
<input [(ngModel)]="foo">

The error in the console

Error: src/app/user-preferences/user-preferences/user-preferences.component.html:13:8 - error NG8002: Can't bind to 'ngModel' since it isn't a known property of 'input'.

13 <input [(ngModel)]="foo">

At this point I'm lost, I don't know where I have done something wrong....

Answer 1

After some times, I finally found it : I did not imported the UserPreferencesModule in the AppModule... So simple, yet so many times... Have a nice day every one !

Answer 2

Please import the below code in your "UserPreferencesModule" module file

import { FormsModule, ReactiveFormsModule } from '@angular/forms';

and below code add in imports array

imports : [ FormsModule, ReactiveFormsModule ]

if you don't want to create a <form> then add this code in your input

[(ngModel)]="foo" [ngModelOptions]="{standalone: true}"

Hope, it might be helpful.
