Encountering an Issue: No directive was identified with the exportAs attribute 'ngModel' while utilizing Template Form in Angular

Here is the HTML code from my-pin.component.html:

<div class="container">
<div class="container">
    <div class="row">
        <div class="col-6" id='pinInput'>
            <form (ngSubmit)="onSubmit()"  #f>
                <label for="pin">Enter Pin</label>
                <input type="number" name="userPin" id="userPin" required ngModel #myPin="ngModel">
                <span class="help-block" *ngIf="!myPin.valid && myPinPin.touched">Please enter your pin</span>
                <button class="btn btn-primary" type="submit" [disabled]="!f.valid">Submit</button>
            </form>

        </div>
    </div>

Also, this is the content of the pin.module.ts file:

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';

import { PinRoutingModule } from './pin-routing.module';
import { MyPinComponent } from './my-pin/my-pin.component';
import { FormsModule } from '@angular/forms';


@NgModule({
declarations: [
MyPinComponent
],
imports: [
CommonModule,
PinRoutingModule,
FormsModule
]
})
export class PinModule { }

The structure of files follows this pattern: pin (contains app.files) -> my-pin (a new module with module files and component files).

Upon compiling, I encountered a 'No directive found with exportAs 'ngModel'' error. The objective is to enforce user input in a number textbox (for a pin) and display an error if no data is entered.

Answer №1

Stumbled upon this in your code snippet myPinPin.touched, it seems like a simple typo. Please correct it to myPin.touched.

 <input type="number" name="userPin" id="userPin" required ngModel #myPin="ngModel">
                <span class="help-block" *ngIf="!myPin.valid && myPin.touched">Please enter your pin</span>

Don't forget to set the ngModel since you are using template driven forms. Make sure to include something similar to the following after declaring it in the component (template)

[(ngModel)]="userPin"

You can find more information on template driven form error handling. Happy coding! :)

Answer №2

Delete the #myPin="ngModel" section and give it another shot
