Hi there,
newbie making first steps with active_scaffold - and starting to love
it :-) However just ran into a problem.
I am using a simple act_as_tree for modeling hierarchically nested
categories.
create_table "categories", :force => true do |t|
t.string "name"
t.string "description"
t.integer "parent_id"
t.datetime "created_at"
t.datetime "updated_at"
end
class CategoriesController < ApplicationController
active_scaffold :category
end
class Category < ActiveRecord::Base
acts_as_tree :order => :name
end
and most things work as expected.
The /categories/ action shows a column "parent" and when a category
has no parent the centered text "Create New" shows up. Clicking on
this, however, produces 500 boiling down to
Processing CategoriesController#new (for 127.0.0.1 at 2010-01-13
11:56:41) [GET]
Parameters: {"parent_column"=>"children",
"adapter"=>"_list_inline_adapter", "parent_id"=>"8",
"parent_model"=>"Category"}
NoMethodError (You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.+):
I find it noticeable that in the lengthy stack trace, active_scaffold
does not show up at all.
This is with rails 2.3.4 and render_component in the rails-2.3 branch.
