uninitialized constant ActionView::CompiledTemplates::Category

ruby-on-rails, ruby-on-rails-3.1

Solution

ok, just for others if they will get into this stupid things as I did, don't forget to have the category.rb in the app/models..

class Category < ActiveRecord::Base
  ...
end

Problem

using this tutorial http://railscasts.com/episodes/57-create-model-through-text-field need to make it work in my app, was on rails 3.0.7 and it worked fine, updated it to 3.1.3 and I got this error now ``` uninitialized constant ActionView::CompiledTemplates::Category ``` I would look for answers more time but now I am really short on time. I have looked into most part of google results related to this problem and no good. Need help please. form ``` <%= f.collection_select :category_id, Category.find(:all), :id, :name, :prompt => "Select a Category" %> or create one: <%= f.text_field :new_category_name %> ``` model ``` class Tvstation < ActiveRecord::Base belongs_to :category attr_accessor :new_category_name before_save :create_category_from_name def create_category_from_name create_category(:name => new_category_name) unless new_category_name.blank? end end ```
