POactivescaffold belongs_to relationship giving routing error
text
Body
copied!<p>I am using the following: Rails 3.0.3 Vhochstein's Fork for Activescaffold rake 0.9.0 ruby 1.9.2</p> <p>I have a model called component which has a belongs_to relationship with category. This was modelled using activescaffold and was working quite well. I took a break for a couple of months and now that I got back to it activescafold gives a "ActionController::RoutingError (undefined method `class_name' for nil:NilClass):" error whenever I try to access the component model. I figured this is due to the relationship (belongs_to). If i remove the relationship from the model, it works. If I add it back it fails!</p> <p>Any Ideas?</p> <p>Here is the Code:</p> <h2>Routes</h2> <pre><code> namespace :admin do resources :users,:roles,:vendors,:shipping_modes,:order_types,:sizes, :suppliers,:categories,:sub_categories, :material_types,:colours, :materials,:styles,:surcharges, :budget_templates, :budget_components do as_routes end </code></pre> <p>end</p> <h2>Controller</h2> <pre><code>class Admin::BudgetComponentsController < ApplicationController layout 'site_admin' active_scaffold :budget_component do |config| config.actions.exclude :delete,:update config.columns[:category].form_ui = :select config.create.columns = [:name,:category] config.list.columns = [:name,:category] config.show.columns = [:name,:category] config.show.columns.add_subgroup "Time Details" do |name_group| name_group.add :created_at,:updated_at end config.list.sorting = {:name => 'ASC'} end end </code></pre> <h2>Model</h2> <pre><code>class BudgetComponent < ActiveRecord::Base belongs_to :category validates_presence_of :name, :category_id validates_uniqueness_of :name end </code></pre>
