HABTM selection conditions
Hi,
I am currently trying to learn RoR and there is something I cannot
figure out.
I have two models: Article and Category, that are HABTM-linked.
Everything works fine if I want to select all articles corresponding to
a category, with something like
@articles = @category.find(@params[:id]).articles
However, I have a ''published'' field in my ''articles''

lost in an ActiveRecord::StatementInvalid
I have an error I don''t know how to debug. I am adding the login
suport in Depot (the example in the RoR book) and
LoginController#add_user throws ActiveRecord::StatementInvalid in an
innocent /login/add_user GET request.
The trace goes down to a call to SQLiteAdapter#table_structure, and
the source code suggests what''s happening is that "PRAGMA

sqlite, views, incorrect data types?
This has been driving me crazy for a few days now. I am using sqlite3
however I have also found this to be the case with 2.8.15:
I have data types text or integer on every column of every table in
the database. Now i know sqlite doesnt care much about data types,
but I believe rails does (correct me if im wrong). On pages that
query a table, everything is perfect.
BUT when I use a view

RJS Templates & Safari?
Hello,
I tried Cody Fauser RJS tutorial
(http://www.codyfauser.com/articles/2005/11/20/rails-rjs-templates)

file_column and tmp files
Hi again...
One more item.. the file_column plugin uses a tmp directory inside the
/public directory to store a temporary uploaded item. But it looks like
this folder is just going to grow and grow. Is there some way to clear
this out or not cause this to happen?
Thanks once again!

Replaced Rails Package with HiveLogic Install - problems
Hi,
I''ve got a strange problem. I had initially installed Rails using Tony
Arnold''s package:
<http://www.tonyarnold.com/articles/category/rails>
and that worked fine. (on OS X, obviously). I then decided to
reinstall using the instructions on the HiveLogic page, to get Ruby
1.8.4:

RoR - Mac OS 10.4.4 on Intel
I got a new 20 inch iMac dual core today and am busy getting it all
setup. A couple of issues though:
1. Is the Ruby 1.8.2 install by Apple still botched or has that been
fixed? I recall someone had fixed the rbconfig.rb to get it working.
Is this something I still have to do?
2. Does anyone know if Locomotive is using the uniersal binaries, or is
it targetting PPC yet? I couldn''t

Error with Rails 1.1RC1 and Properties page
I just tried setting up a simple Rails app, after updating to the

WEBrick started fine with script/server.
I then went to the http://localhost:3000 page and clicked on the
"About your application''s environment" link, and an error was

Question about Associations
Hi all. Got a stupid-simple question about associations. I have two
models - school and course. There are a fixed number of schools (set
up in the migration). Each course is assigned a school and a school
will be associated with multiple courses...
How do I set up the associations? Do (can) I have School :has_one
:course and Course :has_many :schools?
Does the schools table then get a course_id

Authentication and authorization of static content
Hello,
I''m a Java programmer looking to make my life easier. Thus, I''m
considering using Rails for my next project. I''ve read chunks of the
Agile book and it looks like authorizing users at the Controller level
is dead easy to do. However, I have a need to password protect static
content in my site. In the J2EE world, I would use a servlet filter to

Model Structure Advise
Hi,
I''m starting to build a simple (?!) FAQ system, and I''d like some
advice on setting up the model relationships.
I was going to go with a simple system of a Category table and a FAQ
table (holding questions and answers) - where one FAQ belongs to one
category.
That''s all nice - a simple has_many / belongs_to relationship. Then I
decided to add another level - Area.

Looking for DB/Model Design Suggestions
Hi,
I''m working on an app - my first Rails - and am looking for some
suggestions on the best way (or good way) to set up my models / DB. In
general there are teams and matches; a team will participate in multiple
matches, and in each match there will be 6 teams - 3 vs. 3.
I''m going to want to be able, for a particular team, pull up all matches

Which Ruby is my Rails using?
I just noticed something.
I''m running OS X and I''ve installed/updated Ruby to 1.8.4 using the
HiveLogic instructions.
In generating a new app, I noticed that the dispatch.cgi,
dispatch.fcgi and dispatch.rb all start with:
#!/usr/bin/ruby
and not
#!/usr/bin/env ruby
The script/server file does use ''env''.
Now, how will this impact how Rails is run? Will it

How do you move an application to a newer version of Rails?
Hello,
I''ve got an app written in rails 1.1.2 and I need to move it to 1.1.4
Installing the older version of rails is not an option (it''s not my
system) unfortunately.
Thanks,

Save only inserts null instead of actual values
Hi,
whenever I try to save my form, rails only enters null values in my
database. I''m using sqlite, I thought that sqlite might be the problem,
but the problem remains when I switched to mysql. Here is my code:
controller:
class CollectionController < ApplicationController
def new
@collection = Collection.new
end
def create
if request.get?

Routing in Rails
I am fiddling around with some special setups and my routing does not work.
So I wonder: how does routing work in Rails?
Is everything caught by dispatch.cgi script because it is the 404 handler?
What happens with static content? Is it supposed to be found before the cgi
script?
