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?
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
I think he wants to change a child with fields_for and but my not be aware that the method exist, its the only way i can make sense out of his question
