Not sure what the local variable "child" is doing? It's not being used in the 3rd line. I would have expected the code to look like this: parent = Parent.find(params[:parent_id]) child = parent.children.find(params[:child_id]) @dog = child.dogs.build(params[:dog]) This way, you're making sure that the child you find really belongs to the parent. Then, you build a new dog for that child's dog collection. Does this help?
