Hi all, As part of a school project I need to set up an items collection which has categories and subcategories. I have used scaffolding to create these but when i edited the subcategory controller file by inserting this into the edit function: @category = Category.find_by_id(:all) and edited the model sub_category.rb to have the following line in it:
belongs_to :category Now my problem is that when I now click the edit button it comes up with an error: TypeError in Sub_categories#edit Showing ItemCollection/app/views/sub_categories/_form.html.erb where line #1 raised: nil is not a symbol Extracted source (around line #1): 1: <%= form_for(@sub_category) do |f| %> 2: <% if @sub_category.errors.any? %> 3: <div id="error_explanation"> 4: <h2><%= pluralize(@sub_category.errors.count, "error") %> prohibited this sub_category from being saved:</h2> I even removed my changes to those files and the error still appears. Anyone have any ideas what might be causing this? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
