<mat-form-field>
<input matInput placeholder="Especie" formControlName="Especie">
</mat-form-field>
<mat-form-field>
<input matInput placeholder="Nome" formControlName="Nome">

</mat-form-field>

<input matInput placeholder="Tamanho" formControlName="Tamanho">

</div>
Esse é o component.ts
import { Component, OnInit } from '@angular/core';
import { AnimaisService } from '../shared/animais.service';
import { MatSnackBar } from '@angular/material';
import { iAnimais } from '../models/animais.model';
import { Observable } from 'rxjs';
import { FormBuilder, Validators } from '@angular/forms';
@Component({
selector: 'app-animais',
templateUrl: './animais.component.html',
styleUrls: ['./animais.component.css']
})
export class AnimaisComponent implements OnInit {
animal$: Observable<iAnimais[]>;
animalForm = this.fb.group({
IdChip: ['', [Validators.required]],
Tutor: ['', [Validators.required]],
DataNasc: ['', [Validators.required]],
Especie: ['', [Validators.required]],
Nome: ['', [Validators.required]],
Observacoes: ['', [Validators.required]],
Raca: ['', [Validators.required]],
Tamanho: ['', [Validators.required]],
Ocorrencias: ['']
})
constructor(
private fb: FormBuilder,
private snackBar: MatSnackBar,
private animaisService: AnimaisService,
) { }
ngOnInit() {
}
searchAnimal() {
this.animal$ =
this.animaisService.getAnimal(this.animalForm.value.IdChip);
console.log(this.animal$);
console.log('Setando formulario')
this.animalForm.setValue(this.animal$);
}
E o código que eu utilizo para buscar os dados no Firebase é atráves do serviço é esse:
getAnimal(IdChip: String): Observable<iAnimais[]> {
return this.afs.collection<iAnimais>('animais',
ref => ref.limit(1).where('IdChip', '==', IdChip))
.valueChanges();
}
O que eu consegui identificar é que o getAnimal() está retornando um valor indefinido.
async searchAnimal() {
this.animal$ = await
this.animaisService.getAnimal(this.animalForm.value.IdChip);
console.log(this.animal$);
console.log('Setando formulario')
this.animalForm.setValue(this.animal$);
}
