如何通过 API 绑定 FormArray 检索?

How to bind FormArray retrieve by API?

以下是我如何从 API 检索数据并绑定到 angular 中的 FormGroup 元素:

this.api.GetRecipe(id).subscribe((data) => {
  this.form = this.fb.group({
    nome: [data.nome, [Validators.required]],
    ingredienti: this.fb.group({
      acqua: [data.ingredienti.acqua, [Validators.required]]
    })
  });
});

但我不知道如何绑定数组。比如在那里检索farine(这是一个对象数组):

this.api.GetRecipe(id).subscribe((data) => {
  this.form = this.fb.group({
    nome: [data.nome, [Validators.required]],
    ingredienti: this.fb.group({
      acqua: [data.ingredienti.acqua, [Validators.required]],
      farine: this.fb.array([
        this.fb.group({
          quantita: [data.ingredienti.farine[x].quantita, [Validators.required]],
          forza: [data.ingredienti.farine[x].forza, [Validators.required]]
        })
      ])
    })
  });
});

当然 [x] 不在任何地方。每次迭代我在哪里检索 x?或者将数据从 API 传播到每个 FormGroup 的方式是什么?拉姆达?

使用map方法创建formGroup数组

this.api.GetRecipe(id).subscribe((data) => {
  this.form = this.fb.group({
    nome: [data.nome, [Validators.required]],
    ingredienti: this.fb.group({
      acqua: [data.ingredienti.acqua, [Validators.required]],
      farine: this.fb.array(
       data.ingredienti.farine.map(ingredient=>(
         this.fb.group({
          quantita: [ingredient.quantita, [Validators.required]],
          forza: [ingredient.forza, [Validators.required]]
        })))
      )
    })
  });
});
