protect_from_forgery :except => [:create]
skip_before_filter :verify_authenticity_token, :only => [:create]
A quick post on how to send an email with PL/SQL.
There’s a LOT of documentation available at the following link:
PROCEDURE EMAIL_ERROR_REPORT IS
/* Create vars */
v_From VARCHAR2 (80) := 'firstname.lastname@example.org';
v_Recipient VARCHAR2 (80) := 'email@example.com';--REPORT_RECEIVER;
v_Subject VARCHAR2 (80) := 'test subject';
v_Mail_Host VARCHAR2 (30) := 'smtp.test.com';
crlf VARCHAR2 (2) := CHR (13) || CHR (10);
/* Define connection */
v_Mail_Conn := UTL_SMTP.Open_Connection (v_Mail_Host, 25);
UTL_SMTP.Helo (v_Mail_Conn, v_Mail_Host);
UTL_SMTP.Mail (v_Mail_Conn, v_From);
UTL_SMTP.Rcpt (v_Mail_Conn, v_Recipient);
|| TO_CHAR (SYSDATE, 'Dy, DD Mon YYYY hh24:mi:ss')
|| 'From: '
|| 'Subject: '
|| 'To: '
|| 'some message text'
|| -- Message body
'more message text'
/* Catch exceptions */

Just run the following:
Let me know if you come across the cause, I’d be interested to know.
This is the SDK for PayPal adaptive payments. I’ve just uploaded it to *hopefully* make it a little easier to find. Please note that it has not been updated recently and that there are a few changes to be made. The StackOverflow post below provides a few examples:
Adaptive Payments with Ruby
I’ll try to list any others as I come across them, but if you’ve got some of your own please let me know and I’ll try to keep the post up to date.
