fail rollback transaction with manual raise exception

rubyonrails-talk
1

With :   PostgreSQL 8.4 or postgresql-8.3   rails 2.3.4   pg 9.x or pg 8.x

I test this code:

save! just throws an error if there is an issue. Do you have validations that are supposed to cause an exception in that case?

3

Actually you need to put that in an exception block. You are saving the data before the raise.

According to the ActiveRecord documentation, any exception thrown inside a transaction block must rollback all updates have been made within the transaction.

http://api.rubyonrails.org/classes/ActiveRecord/Rollback.html => "Normally, raising an exception will cause the transaction method to rollback the database transaction and pass on the exception"

5

Did you try 'raise ActiveRecord::Rollback' ?

without the .new

Yes I tried 'raise ActiveRecord::Rollback' without '.new', but i have the same problem.

7

what does the corresponding log file look like ?

I'm sorry. The problem was the following code that another developer had added:

class ApplicationController < ActionController::Base   prepend_around_filter :action_transaction

  def action_transaction     ActiveRecord::Base.transaction do       yield     end   end

end

thanks anyway
