    this.afs.collection('installment').doc().set(deal);
    let alert = this.alertCtrl.create({
      title: "ATTENTION",
      subTitle: "Done",
      buttons: ['OK']
    });
    alert.present();
  }
}

我需要将数据发送到Firestore.有人可以告诉我如何发送吗?

I need to send the data to firestore. Any one can please tell me how can I send it?

推荐答案

看起来您正在尝试创建一个新文档，但是当前，您的代码未设置要创建的文档ID.一个建议是让Cloud Firestore使用自动ID.

Looks like you are trying to create a new document, but currently, your code doesn't set a document id to be created. One suggestion is to just let Cloud Firestore use an auto id.

为此，请更改此行:

this.afs.collection('installment').doc().set(deal);

对此:

this.afs.collection('installment').add(deal);
