I added a lot of code to the write method in the project.task model. I need to figure out what's causing the error and for that I need to understand the error. Can someone tell me what this error means or when it's normally raiser.

The whole error message:

I had a constrain on stage_id to send email. The method that send the custom mail causes the error.

the problem was caused by sending subtypes, that were deleted before the mail.mail models _postprocess_sent_message method could written the email_status sent and then delete it. So it was trying to update and delete a record that wasn't there.

So I just inherited the model and overridden the method and the write and unlink statements into try/except. 

I know that this isn't a real fix but more of a bandage. So if anyone can help I would appreciate it.
