The issue of not being able to bind to 'formGroup' because it is not a recognized property of 'form' persisted despite trying solutions from other sources

I have followed the instructions in the guide but I am encountering issues.

An error message stating the following is being displayed:

Can't bind to 'formGroup' since it isn't a known property of 'form'.

Another error occurs when I remove the [(ngModel)] from the items:

[ERROR ->] <ion-input type="text" formControlName="nome" name="nome" required></ion-input>
        </ion-item>
 "): ng:///HomePageModule/HomePage.html@59:10
No provider for NgControl ("
        <ion-item>

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

imports: [
    BrowserModule,
    IonicModule.forRoot(),
    AppRoutingModule,
    FormsModule,
    ReactiveFormsModule 
  ],

 import { FormsModule, ReactiveFormsModule, Validators, FormBuilder, FormGroup, FormControl } from '@angular/forms';

 inscricaoForm;

  constructor(formBuilder: FormBuilder, inscricaoForm: FormGroup) {
    this.inscricaoForm = formBuilder.group({
      dataInscricao: ['', Validators.required],
      nome: ['', Validators.required],
      endereco: ['', Validators.required]
    });
  }

<form [formGroup]="inscricaoForm">

Answer №1

Avoid importing FormModule and ReactiveFormsModule twice.

Additionally, there is no need to inject your own property. Here is a better approach:

app-module.ts

import { NgModule } from '@angular/core';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { AppComponent } from './app.component';

@NgModule({
  imports:      [ BrowserModule, FormsModule, ReactiveFormsModule ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }


app-component.ts

import { Validators, FormBuilder, FormGroup, FormControl } from '@angular/forms';

...

inscricaoForm : FormGroup;

constructor(formBuilder: FormBuilder) {
  this.inscricaoForm = formBuilder.group({
    dataInscricao: ['', Validators.required],
    nome: ['', Validators.required],
    endereco: ['', Validators.required]
  });
}

Aha! I finally figured out the issue. All I had to do was include ReactiveModulesImport in my home.module.ts file. It's funny how such a simple solution caused me so much stress!
