How to iterate array inside an angular / ionic ngFor

Navigation
0

I have the following template: 

export interface Perguntas{
     historico:[{id_historico: number, resposta_historico: string}]
}

In my ts file I perform an http request for a service that returns this data to me, if I give a console.log (this.questions), I get my data as follows:

I need to iterate through this data in my template, I tried something like: 

<ion-card *ngFor="let pergunta of perguntas; let i = index">

<p>{{pergunta.data}}</p>

Here it works correctly, my problem is in iterating the historical array, I tried: 

<div class="message">{{pergunta.historico.pergunta_historico}}</div>

Why does not it work? No error message is displayed on my console, however the value is not shown.

The .historical question is also an array. You have to iterate this array. Something like: 

<div class="message" *ngFor="let historico of pergunta.historico> 
    {{historico.pergunta_historico}}
</div>
