I'm seeing some very strange behavior retrieving a users' private photos from Picasa into Rails. I know that this issue may be relative to my application but I am fairly certain I have eliminated all the variables. I can parse a user's private photos using the data API but now when I try doing it for a different user I get the first user's data! It's as if the server side is caching my token? To replicate:

1) Add UserA with credentials for Google Data to rails db. 2) Get photos for UserA. Everything works. 3) run rake db:migrate VERSION=0, then VERSION=40. I am wiping all my data in rails. Restart the server. 4) Add UserB with credentials for Google Data to rails db. 5) Get photos for UserB. End up with UserA's data!!

Here is my call:

@google_auth = GoogleUser.new(@user, @pass, 'lh2') # I am including my GoogleUser class below @result_string = @google_auth.make_request('http:// picasaweb.google.com/data/feed/api/user/default?kind=photo&start- index=1&max-results=10') # NOTE: I tried switching default to the actual username of UserB but to no avail.

# here is an example of a photo url for the wrong person: @original_filename = @media_node.get_elements('media:content') [0].attribute('url').value

Is it possible this could be happening? Here is my class. Thanks!

require 'net/http' require 'net/https' require 'uri'

module Net class HTTPS < HTTP def initialize(address, port = nil) super(address, port) self.use_ssl = true end end end

class GoogleUser

GOOGLE_LOGIN_URL = URI.parse('https://www.google.com/accounts/ ClientLogin') attr_accessor :email, :password, :header, :service_type

def initialize(email, password, service_type) @headers = { } self.email=email self.password=password self.authenticate self.service_type end

def authenticate $VERBOSE = nil # LH2 very important for Picasa response = Net::HTTPS.post_form(GOOGLE_LOGIN_URL, {'Email' => email, 'Passwd' => password, 'service' => service_type, 'source' => 'formula' }) self.header = { 'Authorization' => "GoogleLogin auth=#{response.body.split(/ =/).last}", 'Content-Type' => 'application/atom+xml' } end
