Rubberband Wound

Just a little thought I thought I should be sure to share, as it’s something I wasn’t aware of until this morning.

If you load an object in Rails and load any of it’s relatives through acts_as_tree, and then destroy the object, it will take the relatives with it.

@person = Person.find :first

@person.children.each do |child|
   child.reassign_to_parent(x)
   child.save
end

@person.destroy

The above code will destroy all of the children as well. My solution was to do a reload after I messed with the children.

@person = Person.find :first

@person.children.each do |child|
   child.reassign_to_parent(x)
   child.save
end

@person = Person.find @person.id

@person.destroy

This clears out the object’s knowledge of the children, and that destroy will leave the children alone.
