Symlinks in Capistrano?
I have a few projects with large directories (say, user-uploaded files) that
make using Capistrano a bit awkward. However, I suspect that I may have
reached the "write a custom task" level.
(I suppose I''m just thinking out loud, here...)
It seems as though I''d want this directories symlinked in /shared... Maybe
there''s a way to extend the

The perfect development environment?
I am trying to create the perfect development environment for rails
and i dont know exactly which way to go. Do i create a windows
environment or a *nix environment. If i go *nix, what distro is best
suited for rails. I would be using mysql, so that would come in to
play. If i go *nix, i would use apache. Any ideas for the right
environment would be greatly appreciated. I guess the major choice is

Transactions and migrations (lots of records)???
Hi all -
I know this must be really easy to do, but I can''t for the life of me
figure it out.
I have about 100,000 rows I need to migrate over into rails using a
migration.
Right now, I select all of them out of the old database and do a series
of:
...
new.col = old.col
...
new.save
...
Problem is each one is it''s own transaction. And it''s slow. I''d

New Model Object from Existing Model Object
Hey Guys, need a hand again....
Lets say I have an Order... and an Order has Order Lines and Order_Lines
have Items...
I want to create a New Order, which would have New Order Lines with the same
Items...
Is there a fast / easy way to do this, w/o having to create a new order,
loop through all the order lines, and create them associating them with the
Items?
Any help would be great, thanks

When to make a new controller
Hey all,
Ok this is probably a newb question, but I haven''t been programming with
MVC for very long, and I''ve been wondering what the general opinion is,
or best practices, for making a new controller. Like what cases would
you need a new controller for and what cases can you just put everything
into one controller?
Thanks in advance,

using select_date causes errors...
I''m getting errors whenever the user chooses, for example, April 31st (
since there is no 31st in April, navicat freaks out ), there MUST be a
method that ruby has that would allow me to validate a date before I
submit to navicat.
I haven''t been able to find anything online about it either, it''s
probably something simple, I just can''t figure it out.
Thanks

before_destroy & verification
Hey, probably an easy question but,
I''m trying to get a method to run "before_destory" for a model, and I
want the method to throw an error, and not delete the object from the
database, if a certain condition is held
Obviously, I can just raise an error and rescue it... but for some
reason I can''t get <% error_messages_for ''model" %> to catch

Invoice and invoice_lines
Hello People,
I have a possibly very lame question.
I am fairly new to RoR, and I want to make sure I do it "right".
I have a model called Invoice, and one called InvoiceLines. Usual story:
the table "invoice" has a 1:n relationship with "invoice_lines", which
includes invoice_id.
Now... the application will have a "new order" button, which will allow

Stuck on ActiveRecord
Hi,
I''m having great fun developing with Rails but I''ve come to a problem
that I can''t quite figure out.
I have an Order object that "has_many" order_lines. This works perfectly
and I can see all the lines.
The OrderLine object has an order_id field as well as product_id and
amount.
Now ideally I would want to do :

Hi..Guys new plugin again
Hi..
Guys new plugin again
Foreign Key Associations is a plugin that automatically creates
associations based on foreign-keys. The associations are created at
runtime-ie. as your ActiveRecord models are loaded-so they will always
be up-to-date.
For example, given a foreign-key from a customer_id column in an
orders table to an id column in a customers table, the plugin
creates:

How to force a lock_version increment
Hi everyone,
I have a order with order_lines use case. On changing the lines, I
want to be sure no one else changed the order. So I use lock_version
on the order. This works fine if something is changed on the order
record.
But now i have the situation that I delete, alter and add order lines
without changing the order record itself. I have to check and
increment the order#lock_version however

Ignoring Validations In An Admin Tool?
I have the following validation on and ''Order'' model:
validates_presence_of :order_lines, :message => ''missing one or more
products.'', :on => :save
Ok, great. An order has to have products. Ok.
Problem is, there are some old orders that don''t have lines (don''t ask) and
in the admin tool we need to be able to work on these orders.

Samba 3.0.22 PDC trusting Active Directory 2003
I'm a longtime Samba user and admin (since 1.7) and I thought I had seen just about everything until Active Directory 2003 (native mode) completely took out our Samba user authentication (each server auth=domain to an AD 2000 domain). We have Samba running on a variety of servers (AIX, HP, Linux) and need to be able to provide our users with the ability to access their appropriate shares
