Activerecord::JDBCError: Invalid column number
Hi,
I''m rather new to Ruby and RoR, so I do not really know whether this ist
the right forum to place my question.
For my first ''project'' I planned to create a simple online-viewer, which
grabs data from an existing database and make them visible in a
structured form via browsers. So I thought that could be the right
beginner-project, because I have only read datasets

Strip & Sanitize BEFORE saving data
So I''ve googled my brains out, and I see a lot of talk about
TextHelper for views, but next to no discussion about cleaning text
_before_ it is saved.
I figured this had to be asked 4 zillion times, but I''m not finding
anything concrete/obvious.
Using h is fine as a safety catch, but that alone is not acceptable
to me as the means of diffusing the impact of HTML or JS

Newb - variable returns # sign?
Hi Gurus-
I want to return the variety from the species table based on the
active record link to inventory table
class Species < ActiveRecord::Base
has_many :inventories
end
class Inventory < ActiveRecord::Base
belongs_to :species (this is the singular and the plural, so that''s
OK)
end
My inventory_controller looks like:

Can't get simple link_to_remote to work
AFAICT, this is all I need to do to get a simple example working:
the <head> should have this:
<%= javascript_include_tag :defaults %>
My test page view should have a div with an id and the ERB like this:
<%= link_to_remote ''Click Me'',
:url => {:action => ''show_time'',
:update => ''time_box''} %>

Talking to Java APIs
I''m trying to figure out how Ruby in general, and/or anything extra
Rails may have, can talk to Java APIs of third party server apps.
After quite a few search attempts net-wide and on ruby forums, and
with "Programming Ruby" in hand, I''m coming up with zilch. Either I''m
not finding it, or I''m not recognizing it.
I''m assuming there has

Capture IP Address to Sessions
What I''d like to do:
Capture the IP addresses of the folks visiting a web site in the
Sessions table.
What needs to be in place (code, model, controller, etc.), where does
it need to go (application controller?), how best to set up the
Sessions table?
Appreciate a noob-friendly outline of what needs to be done.
Thanks.

Route Information
Is there a method to return a hash of the route configuration based on
a path?
For example:

{:controller => ''my_controller'', :action => ''my_action'', :id =>
''my_id''}
Thanks!

Alternative to storing ActiveRecord object in session
I''m writing a wizard-like module in my application where, in a series
of steps, the user builds upon an ActiveRecord object, and in the end,
saves the AR object into the database. The ActiveRecord object is
fairly complex, with a has_many association that could potentially get
large, so I don''t want to store it directly in the session. In fact,
having done so already caused a

How show validation errors in form_remote_tag?
I suspect this has been asked 400 times, but Google yields 2-3 rather
complex gymnastics in blogs (and possibly dated), and searching list
archives on ruby-forum proves kinda useless.
Using standard forms, it''s fairly easy to use
@object.errors[:field_name] in the form to embed an error message right
next to the field that has the invalid entry. The controller uses a
simple conditional

Column aliasing in ActiveRecord?
Anybody know of a way to alias a column in ActiveRecord such that you
could reference it via a different symbol in your view for view
purposes?
Like my column is named X but I want to display it as Y and maybe I have
an accessor named Y set up on the model so that when I "call" Y from the
view (and controller?) I''m actually manipulating the column X?
Hope that makes sense.
