YAML inconsistencies...
I figured I''d post here before submitting a ticket, but I''m seeing some
confusing stuff when dealing with YAML now. I was using it to freeze
objects in my database, and so i had some data already around to mess with.
I upgraded both Ruby (1.8.3 -> 1.8.4) and Rails ( -> 1.1RC1) and this junk
started. I''ve outlined the problem in two pastes, which I''ll

find_by_sql vs connection.select_all
I was trying to do SUM based mySQL query simliar to the following:
SELECT SUM(updated_on - created_on) AS total from signups
If I were to run this command in the mySQL console I would get a
result. However, if I were to run it using the following command in
Rails:
Signup.find_by_sql("SELECT SUM(updated_on - created_on) AS total from
signups")

rake migrate VERSION=0 doesn''t appear to execute
All,
I''ve decided to jump into Migrations before I get too far along on the
DB side of things.
I already have some tables built, and I went ahead and built the
migration that would have created them from scratch, and I made sure
that there was a self.down section to drop them. I wanted to verify
that I could roll back so I figured I would use rake to drop these
pre-existing tables

Question: Migration - multiple creates
I want to create a migration file that creates multiple tables, so i''m
guessing the correct format would be:
Can anyone confirm ? I''m guessing that each new create script requires a
seperate class so formatted this way. Perhaps I''m wrong.
TIA

how to search date with ferret and acts_as_ferret?
Hey all,
How can I search date with ferret? Do I need to submit them in a special format?
Right now I have in my Item model:
acts_as_ferret :fields => [:created_on]
with eg created_on = Thu May 11 17:00:00 -0500 2006
now when I do Item.find_by_content("created_on:<#{Time.now}")
I get nil, I''m probably doing something wrong.
Any idea how to fix it?
thanx in advance

Dead horse: validates_associated
Regarding validates_associated...
Let''s say I have:

anonymously and therefore not require an author. Then I have:
Article:
belongs_to :author
validates_associated :author
But I DON''T have validates_presence_of. What I want to do is validate
