How to prevent anonymous keys on Firebase?

Question

I'm working on a chat project on the platform Raspberry PI 3, Openelec OS.

Trying to write to the DB and getting unwanted anonymous keys.

Unwanted key marked with yellow. Movie2 and it's keys and values are the wanted result, but I made it manually.

I only ask how can I prevent this anonymous random key to be there and how can I replace it with other key? (string, a movie name for example)

This is my code:

url = 'https://chat-example-97c62.firebaseio.com/Movie1.json'
postdata = {
    'date': str(time.asctime( time.localtime(time.time()) )),
    'temp': str("Hello from Kodi")
 }
req = urllib2.Request(url)
req.add_header('Content-Type','application/json')
data = json.dumps(postdata)

Thanks.

When you send a POST request to Firebase, it automatically generates a Key (Anonymous Key), if you want to use your own key you need to use a PATCH request, this is an example on Python 3:

def update_entry(user, message):

    my_data = dict()
    my_data["user"] = user
    my_data["message"] = message

    json_data = json.dumps(my_data).encode()
    request = urllib.requests.Request("https://<YOUR-PROJECT-ID>.firebaseio.com/movies/<REPLACE_THIS_WITH_YOUR_DESIRED_KEY>.json", data=json_data, method="PATCH")

    try:
        loader = urllib.request.urlopen(request)
    except urllib.error.URLError as e:
        message = json.loads(e.read())
        print(message["error"])
    else:
        print(loader.read())
