Is there one command to save an ActiveRecord and all dependents?

Rails

Hi,

When testing, I sometimes modify a parent object, save it, but then
get tripped up bc the dependents do not reflect the change (maybe that
should be obvious.)

I’m wondering, is there a command that saves an ActiveRecord instance
and all its dependents?

Thanks,

Lille

you can call save on the childs but there is also this method

accepts_nested_attributes_for :child

thats how is was called in rails 2 try finding out if its called the
same in rails 3.

instead of child put the name of the child model

Why should you need to save the dependents if it is only the parent
that you have modified?
