fieldTransform

[fellnerse]

Hey just another quick question:

is it possible to use fieldTransform like this: https://stackoverflow.com/questions/57779415/cloud-firestore-rest-api-add-server-timestamp
to get a servertimestamp? If so, is it possible to use this as document id as well?

No, the library is not support the document commit at this time.

Now the library update, v2.1.6 is available which document commit is added.

This is the example for document commit which you can try.

this looks really cool; Not too sure yet how to combine with the create document example tho, this way makes it more complex I think; somehow the time serve I currently use hase sometimes issues (i.e. returning year 2036), thats the reason why I would like to use this

I probably need to send 2 requests, right?

[mobizt]

Yes because of Google APIs design.

The Cloud Firestore APIs are complex and very flexible as its data can be complex and flexible too.

The Cloud Firestore is suitable for all support platforms instead of low memory device.

[fellnerse]

Yes I understand, I'm only posting data to the firestore, so I think the rest api works fine. Now I have to see if its worth to double my number of requests..

For timestamp server value, it sets to the defined field path. You need to read value (timestamp type value) from that field path later.

The result payload when use get document function with assigned document mask for timestamp field path will be as below.

{
  "name": "projects/<projectId>/databases/(default)/documents/<collectionId>/<documentId>",
  "fields": {
    "<fieldId>": {
      "timestampValue": "2021-05-11T08:59:02.072Z"
    }
  },
  "createTime": "2021-05-11T07:00:53.792691Z",
  "updateTime": "2021-05-11T08:59:02.107983Z"
}

You may need to parse the timestampValue which is the string in the payload to Unix timestamp or time yourself.
