After *much* digging and playing around, I finally figured out how to unit test instance variables that are created by actions. It was more difficult than I expected.

But get the following error when trying to access http://127.0.0.1:3000/recipe/new Errno::EINVAL in RecipeController#new Invalid argument

Postgres database. I have a categories table, with two columns id, and name. I have a recipes table, with a category_ids column.

When following the ONrails "Rolling on Ruby with Rails" tutorial part1 I (already) encountered the first complication. After doing those basic actions to set up the basic site, the tutorial tells me to overwrite the "list" method included in the "scaffold :recipe" method which we find in the recipe controller with this code: def list @recipes = recipe.find_all

I''m having a problem getting this example from the book to work: class Cookbook attr_accessor :title, :author def initialize @recipes = [] end def method_missing(m, *args, &block) @recipes.send(m, *args, &block) end end cb = Cookbook.new cb << recipe_for_cake cb << recipe_for_chicken beef_dishes = cb.find_all {|recipes| recipe.main_ingredient ==

And then I should be ready to roll with my project.. I have some fine tuning of the looks to do after, but funtionality first! This is probably a rails question.. but I''m not sure where to sign up for the rails questions email group? (I guess I turned this into a 2 question email).

I''m three pages into the OnLamp RoR Tutorial [1] and am wrestling with what appears to be a MySQL connection problem. I''ve created a simple controller called "recipe" with a corresponding "recipes" mysql table. The recipe controller is just a simple scaffold.
