谷歌云数据存储查询

Question

Trying to locate data based on its Name/ID field which is auto generated within Google cloud. I want to be able to update the given entity, however I am finding it hard to work with the data formatting. I have a list of data with a button which says 'Update" when clicking the update it gives the Unique Name/ID of that entity, however i cannot seem to find a method of also pulling the information associated with that Name/ID within google cloud.

Table with data in

Data inside google cloud

Unique ID located but struggling to pull the other data based on that ID

def updateSong():

    songID = request.form['Update']
    # songQuery = datastore_client.query(kind="Song")
    # songs = list(songQuery.fetch())

    query = datastore_client.query(kind='Song', ancestor=songID)
    songData = query.fetch()

    print(songData)

    id_token = request.cookies.get("token")
    error_message = None

    if id_token:
        try:

            user_data = google.oauth2.id_token.verify_firebase_token(
                id_token, firebase_request_adapter)

        except ValueError as exc:
            error_message = str(exc)
    
    return render_template('UpdateSong.html', user_data=user_data, error_message=error_message, songID=songID)

Is there not a method of querying the song ID to then be able to use it as such:

song['Title'] = song title

Answer 1

Try this

    query = datastore_client.query()
    query.key_filter(datastore_client.key('Song', songID))
    song = list(query.fetch())
