Angular: No value accessor for form control with unspecified name attribute

Jun 21 2021 58

I have a small project with Angular 9. And I have a component as below:

 @Component( {
    selector: 'switch-extra-field',
    template: `
            <div class="form-group" [formGroup]="formGroup" >
                <switch [attr.title]="field.etiquette" 
                    [attr.value]="field.valeur" [(ngModel)]="field.valeur"
                    [formControl]="fieldControl" [attr.id]="etiquette">
                </switch>
            </div>
    `
} )

When I run this component I got an error No value accessor for form control with unspecified name attribute.

 ERROR Error: No value accessor for form control with unspecified name attribute
  at _throwError (forms.es5.js:1918)
  at setUpControl (forms.es5.js:1828)

How can I resolve it?

    You can try to use ngDefaultControl directive to make your form has default 2way binding.

     <switch [(ngModel)]="name" ngDefaultControl></switch>

    I hope it works for you.

    I think the message error throw is very clear. you lost name attribute to the element has [ngModel]. To fix this issue, you can add more name="fieldName" ngDefaultControl to your element.
