I have a field on the form with radio Buttons:

<div class="form-group" >
     <label class="control-label col-md-4">Tipo Atividade2*:</label>
     <input type="radio" [(ngModel)]="atividadeFixa" value="true" required> Fixa<br>
     <input type="radio" [(ngModel)]="atividadeFixa" value="false" required> Não Fixa<br>
</div>

I need to Load the value who comes from the back to the front. How can I do this ?

object code:

export class Atividade {

    atividadeFixa: boolean
}

code service

editarAtividade(atividade : Atividade) : Observable<any>{
        //return Observable.of("Edition not implemented yet")
        let params = this.setParamsAtividade(atividade)
        params.set("atividade", atividade.id.toString())
return this.http.doPut(Rotas.ATIVIDADE, params)
}

How you are using ngModel only change the property value atividadeFixa.

I did in stackblitz an example with setTimeout() and changing the value of it kind of simulates a request.

  • just vc create a method and change the ngModel value in it
