validates_uniqueness_of where scope euqals created_by "magic" field
I have the following ActiveRecord objects:
class Recipe < ActiveRecord::Base
has_many :ratings, :dependent => true
. . .
end
class Rating < ActiveRecord::Base
validates_uniqueness_of :created_by, :scope => :recipe_id
belongs_to :recipe, :counter_cache => true
. . .
end
The created_by field on Rating is implemented as a "magic" field
similar to this:
http://wiki.rubyonrails.org/rails/pages/Howto+Add+created_by+and+updated_by.
It is working fine.

more work: to rename all the primary id''s in the legacy database, or to
work around the fact that the primary id''s are not called ''id'' within

I''ve been successful in using a join table with two fields named
''recipe_id'' and ''tag_name'' to relate a table called Recipes with a table
called Taggs, using this model:
class Recipe < ActiveRecord::Base

Active Record Query
...has many lessons and a lesson has many topics.
A topic can have a recipe or vice versa, a recipe has many topics
(optional).
I need to come up with the most efficient way of querying the database
to find those topics belonging to a course (via lessons of course) which
have a recipe (in other words recipe_id is not null for this topic
record).
Simple but challenging :)
Thanks for your time.

Getting Foreign Key to work!
Okay. So I have this simple site, which includes Recipes and then
Comments.
I want ppl to be able to comment on the recipes, and so I made comments

to not know that stuff.
When I click on a recipe, and then make a new comment and click ''submit''
(for the comment) it submits it, but it still has recipe_id as nil! I
know how to make the comment know that i...

In a find, can''t you use both :include and :limit ?
...t_update` AS t0_r10,
employees.`is_featured` AS t0_r11, employees.`is_deleted` AS t0_r12,
employees.`is_hidden` AS t0_r13, skills.`id` AS t1_r0,
skills.`parent_id` AS t1_r1, skills.`name` AS t1_r2, skills.`desc_short`
AS t1_r3 FROM employees LEFT OUTER JOIN skills_employees ON
skills_employees.recipe_id = employees.id LEFT OUTER JOIN skills ON
skills.id = skills_employees.skill_id WHERE (skill_id = 3)
But remember, I want to use this in a Pagination scenario, and that''ll
require :offset and :limit. Let''s add them in as a test.
