using select() to relate tables
I''m sorry to be asking trivial questions, but I''m new to RoR and am
hooked :), so I''m very impatient to get things up and running.
given two related tables, "pcs" and "venues" (venues have many PC''s and

names in the "new PC" form along with other PC details to

splitting a story with double-spaced para''s
Quick question - if i want to separate a long string of text, separated
by single carriage returns, into an array of paragraphs, I can use the
following code:
paragraphs = article.content.split("\n")
The "\n" means a carriage return, as far as I can tell.
If I wanted to take text, that had been written using the more common
double carriage returns, into an array of

Button on view
Hi,
I have a page containing 3 views (2 are partials). One of the partials

Newbie - populating select list from db
Can''t seem to find an example of this anywhere - how do I populate a
select list in a form from a database?
I have a form to create a new task. The task is for a client, so there
should be a select list populated from my clients table. I thought this
would work:
<%= select ''task'', ''client_id'', Client.find_all, "id", "name"

why belongs_to does not like validation?
This works :
class Recipe < ActiveRecord::Base
belongs_to :category
end
But (when I add validation) this does not work :
class Recipe < ActiveRecord::Base
belongs_to :category
validates_length_of :category, :within => 6..20
validates_uniqueness_of :category, :message => "already exists"
end
thank you

Firefox won''t let me send ''&'' with AJAX!
Hi everyone,
I''ve encountered a HUGE problem, which may not be RoR-oriented, but
there might be a workaround somehow.
See, at this moment, I''m unable to send AJAX requests back and forth
when the information contains an ampersand (''&''). In essence, request is
never completed. The odd thing is that it only happens with Firefox (IE
and Opera works fine).

Can''t get select helper to populate dropdown w/default value
Guys,
I searched this forum and found plenty of people having this problem,
but I didn''t see any definitive solution. Usings Rails 1.0.

display the current value contained in the field of the record. All of
my other (text) fields populate correctly with current field values.

find(:all) vs find_all
I started with Ruby on Rails in the 0.13.x period, so I''m sure I
missed out on a lot of history. There''s probably some good
explanation for something I''ve been wondering about, but I haven''t
seen it written down anywhere. Maybe someone can clue me in.
I''ve always felt that one of the uglier APIs was the
