[Request] file_column configurability
I wasn''t sure where to email this request, so I am hoping the author of
file_column actually sees this. I was wondering if there were any plans to
allow some configurability in the file_column plugin. By configurability I
mean allowing the developer to define which table column is used as the
unique identifier when creating image folders. Right now it seems like it
uses the ID of the

Integrating with Legacy Databases
This seems like it must have been asked before - I really _did_ try to
find it in the archives, so my apologies if it''s already out there.
Utilizing ActiveRecord, I would like to specify a prefix for the
column names in my table. For example, in ''Recipe 16 Integrating with
Legacy Databases'' (Rails Recipes, from PragProg, by Fowler) they deal
with integration with a

Rails from the command line
I have controller that processes data in one table and puts results in
another. Now that its'' working, I would like to be able to run it from the
command line ( read: windows batch file). How can this be done?
It will be installed on a Windows box with InstantRails1.0, (if that
matters).
I will be doing more processes like this, so this is a good opportunity to
get it right.

how do I validate currency format if I am storing in cents?
Hi all -
To avoid floating point issues, I''ve decided to store monetary values in
cents in the database. However, the user will enter these in dollars
and cents. Two questions:
1) How do I do the validation for the currency format? It looks like
ActiveRecord truncates the cents since it thinks the field type is a
Fixnum. Am I forced to do validation in the controller?
2) Where

How to Affect Plugin Load Order
I''m using bundled_resource, login_engine, and a few other plugins. It
appears Rails considers plugins in alphabetic order. Turns out that
there is a particular order that will work and alphabetic ain''t it.
The login engine must be loaded first. Bundled resource then includes
''application_helper'' and the application helper includes LoginEngine. If

I just can''t figure it out !
Howdy RailsWarriors,
Its probably dead easy but I don''t see it.
Got this in my controller.
def new_computer
User.find(params[:id]).computers.create(:comp => ''New Comp:'')
end
Which with an .rjs template creates a div at the bottom of my list.
This all works like a charm.
But in the partial I load in my rjs I also have a button for ''delete'' in

Bizarre problems with AJAX / missing variables

Everything is working as expected on my development machine (OSX,

Guys,

Form validation - keepin correct fields displayed on refresh
All,
I''m finally doing my first real form in Rails - the model object that
I''m entering information for has 8 validations so far.
If I type in good values for all the fields but one, I get the pretty
validation, and the nice field highlighting, but all of the fields are
cleared, forcing me to retype all of that info. That is a big drag.
Is there a standard way to get the

acts_as_list and single table inheritance
in a single table inheritance model, rails will automatically set the
scope for acts_as_list to the ''type'' field as well as any other scope
conditions we provide.
Is there a way to disable this? i want to use STI but I want
acts_as_list to disregard the class type when getting/setting
positions.

ajax insertion into a form
After an ajax insertion in the dom, it seems the browser don''t
refresh its knowledge of the page.
The source of the page is identical after the insertion, whereas the
display is correct.
The ajax insertion is used to add an input field. The added fields
are ignored by the submission of the form.
Isn''t it possible to do that, or maybe there''s a problem in my code

Issue in ActiveRecord generated reader methods
Hi all!
I have come into a strange issue in Rails that I am hoping someone
can shed some light.
To make a very long story short, I have been researching how to
override ActiveRecord::Base#read_attribute and write_attribute to
perform security checks at the model level (influenced by the
ModelSecurity generator). Shortly after implementing some code to
check this behavior, I began to
