Tutorial for Queries
Hi! I''m looking for a good tutorial that explains the main points of
performing queries with Rails. I do have AWDWR and have read the
section on ''find'' but I''m looking for something that goes into more
detail on how to perform queries across tables.
Abstracted from my current application, this is an example:
* person has_many sites
* site has_one room

How to pass a collection to paginate?
There must be a better way to write this code:
@project_pages, @projects= paginate :project,
:per_page => 10,
:conditions => ["account_id = ?", account]
?!
If only I could pass the sub-collection
account = ...
@projects = account.project
to paginate, instead of letting it extract it with a find :all + sql
conditions

Pagination Question
Hi -
I''ve just started working with Rails, having come from a Cold Fusion
background. I''m curious how best to deal with a huge result set. For
example, I''m building an app that contains users. I''ve used
scaffolding to setup my initial pages for CRUD operations on users.
All that is great. The problem is, I''m going to end up with 1000+

custom find methods and pagination
i''ve got several methods in my models i use to find based on certain
criteria...i''ve done this so the controller code is less cluttered, plus the
DRY factor.
example:
class Foo < ActiveRecord::Base
def find_by_something(something)
find :all, :joins => ..., :conditions => ...
end
def find_by_something_else(something_else)

pagination over custom-sorted collections?
I have a little web app where we need to paginate collections of
items. I''m trying to sort the collection and then pass it, sorted, to
a Paginator, and still be able to paginate through the collection,
across several pages, with the new sort order. The only thing I''m
doing differently from the regular scaffolding approach is this:
@order_pages = Paginator.new(self,

How to paginate in descending order?
How can I paginate a set of fields in descending order based on their
created_on date?
For example, in a blog app, you want the very first entry on the first
page to be the most recent.
I see that paginate has an :order parameter, but I don''t see any way of
changing the direction of the order.
Thanks,
Jeff Coleman

Engines question
I would like to get at all models in a rails application to be able to
add a field to every one of them as part of a migration. Something
like the following:
Appmodels.each { |x| add_column x.table_name.to_s, :foo, :text }
I understand I can get the table name using
ActiveRecord::Base#table_name, but how do I get all the models into an
array that I can use in the above manner?

Migration?
I just installed ruby, lighttpd, and mysql from darwinports on me
laptop in lieu of the Apple version of ruby. Now when I fire up my
rails application, it''s not running lighttpd anymore -- it''s running
webrick. It also exits immediately. MySQL is running, the database
and tables are restored from the backup. What step am I missing?
Thanks for the help!
