#save(perform_validation = true) {|result| ... } ⇒ Object

This is where all of the magic happens. This is where we hook in and add all of the OpenID sweetness.

I had to take this approach because when authenticating with OpenID nonces and what not are stored in database tables. That being said, the whole save process for ActiveRecord is wrapped in a transaction. Trying to authenticate with OpenID in a transaction is not good because that transaction be get rolled back, thus reversing all of the OpenID inserts and making OpenID authentication fail every time. So We need to step outside of the transaction and do our OpenID madness.

Another advantage of taking this approach is that we can set fields from their OpenID profile before we save the record, if their OpenID provider supports it.

Yields:

  • (result)
