Hi all, When submitting a master/detail form I first want to handle the children before saving the parent. There are has_many and belongs_to relations between the parent and the children, so I can edit the children using (psuedo-)code like: child.destroy for deleting, child.update_attributes for updating and @parent.children.push(child) for adding child-records. I update the parent by using:

Hi, In Agile Web Development with Rails section on Transactions (p 381) there are two main examples. 1) making changes in two records in the same database table 2) making changes in two records each in a different *database* I want to do what is in between: changes in two records each in a different table of the same database. Suppose they are apples and oranges tables. How do I write this?

I''m trying to enhance acts_as_nested_set. Well actually I already have, but I''ve done a hack up job of it. I would like to contribute these enhancements back, but I need a little help.

I have an import script that uses ActiveRecord, but it is generating a single transaction per SQL query. My import script is also threaded, so I don''t want to use ActiveRecord::Base.transaction {} blocks in my threads. Is there a config option that will just let me turn off transactions altogether?

Hello all. I''m working on a program that uses both ActiveRecord and PDF::Writer. The latter requires the Transaction::Simple module, and ActiveRecord contains a "built-in" copy of Transaction::Simple - but the namespaces appear to clash, if I''m understanding things correctly.
