Uses the PATCH method to update record with new information. The data used in this example is at Chilkat Firebase Pigs Database, and is shown here:

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

# Uses the PATCH method to update a Firebase record.

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# This example assumes a JWT authentication token, if required, has been previously obtained.
# See Get Firebase Access Token from JSON Service Account Private Key for sample code.

# Load the previously obtained Firebase access token into a string.
fac = Chilkat::CkFileAccess.new()
accessToken = fac.readEntireTextFile("qa_data/tokens/firebaseToken.txt","utf-8")
if (fac.get_LastMethodSuccess() != true)
    print fac.lastErrorText() + "\n";
    exit
end

rest = Chilkat::CkRest.new()

# Make the initial connection (without sending a request yet).
# Once connected, any number of requests may be sent.  It is not necessary to explicitly
# call Connect before each request.  
success = rest.Connect("chilkat.firebaseio.com",443,true,true)
if (success != true)
    print rest.lastErrorText() + "\n";
    exit
end

authGoogle.put_AccessToken(accessToken)
rest.SetAuthGoogle(authGoogle)

# Chilkat's sample data (pig-rescue data) is publicly readable at: https://chilkat.firebaseio.com/.json
# This data is publicly readable, but not writable.  You'll need to 
# run against your own database..

# We're going to update "Molly II" to "Molly III"
pigNameUpdate = Chilkat::CkJsonObject.new()
pigNameUpdate.AppendString("name","Molly III")

# The string content of the last arg passed is  {"name":"Molly III"} 
jsonResponse = rest.fullRequestString("PATCH","/pig-rescue/animal/-KI3bD-FU_Dake7sYOiP.json",pigNameUpdate.emit())
if (rest.get_LastMethodSuccess() != true)
    # Something happened in the communications (either no request was sent, or no response was received.
    # (The Chilkat REST API also has lower-level methods where an app can send the request in one call,
    # and then receive the response in another call.)
    print rest.lastErrorText() + "\n";
    exit
end

# Check the response status code.   A 200 response status indicates success.
if (rest.get_ResponseStatusCode() != 200)
    print rest.responseStatusText() + "\n";
    print jsonResponse + "\n";
    print "Failed." + "\n";

end

# When successful, the response contains the data written.
