Organise ActiveRecord model into a tree structure

ancestry's Issues

parent_id in a form returns "undefined method"

I am not sure if this is related to the port and the modifications, but I noticed that when I am trying to do a simple "hook-up" of a model, it won't work.

This is my class:

class Node < ActiveRecord::Base
  has_ancestry orphan_strategy: :adopt, cache_depth: true

This is my schema for my Node.rb table:

# == Schema Information
#
# Table name: nodes
#
#  id             :integer          not null, primary key
#  family_tree_id :integer
#  created_at     :datetime
#  updated_at     :datetime
#  name           :string(255)
#  ancestry       :string(255)
#  ancestry_depth :integer          default(0)
#  max_tree_depth :integer          default(0)

This is my controller create & new actions:

  def new
    @node = Node.new(parent_id: params[:parent_id])
    respond_with(@node)
  end

  def create
    @family_tree = current_user.family_tree
    @node = @family_tree.nodes.new(node_params)
    @node.save
    respond_with(@node)
  end

My _form.html.erb (which is a simple_form, for what it's worth):

<%= f.input :parent_id, as: :hidden %>

This is the error I am getting:

undefined method `parent_id' for #<Node:0x007fac361ba1e0>

Any ideas?

For what it's worth, I swapped out the gems in my Gemfile and it works - as is - with the stock gem.

Here are the server logs for the working version:

What is the setter for parents?

@tjchambers How do I actually set the parents of an object?

In my _form.html.erb for my Node object, I have the following:

<div class="field">
  <%= f.input :parents, collection: @node.family_tree.nodes - @node.parents, label_method: :name, value_method: :id, label: "Parent 1" %>
</div>

In my Node.rb model, I have this:

attr_accessible :name, :family_tree_id, :user_id, :description, :parent_id, :parent, :parents

In my NodesController.rb I have this:

private
def node_params
  params.require(:node).permit(:user_id, :family_tree_id, :name, :description, :parent_id, :parent, :parents)
end

But when I try to assign a parent to a Node, I get the following error:
unknown attribute: parents

I suspect it is because there is no parents setter.

How do you set them without it?
