Wrap error_messages_for() call when no instance var present
I am trying to put some smarts around a call to
<%= error_messages_for %>
so that when I first come into this page i.e. when my instance variable
@target_list has not been defined yet, the page doesn''t break.
I''m doing this:
<% if @target_list? %>
<%= error_messages_for ''target_list'' %>
<% end %>
I get a syntax error on line 1.

Best way to organize non-controller logic???
I don''t want to put certain code in my controller because I think it
makes things more confusing.
What is the best way to manage business logic such that it doesn''t end
up in the controller?
Basically, where should I put my regular utility classes and backing
objects that may not be models?
Thanks,
Wes

rake migrate VERSION=0 doesn''t appear to execute
All,
I''ve decided to jump into Migrations before I get too far along on the
DB side of things.
I already have some tables built, and I went ahead and built the
migration that would have created them from scratch, and I made sure
that there was a self.down section to drop them. I wanted to verify
that I could roll back so I figured I would use rake to drop these
pre-existing tables

<%= foo %> //foo is a string or returns a string

What is the method of "writing to the output stream" in RoR? Basically,

HABTM join table has an "ID" column - is this an issue?
All,
I''m building model objects for existing tables that I cannot modify.
In AWDWR, Dave says "Note that our join table has no id column...The
second reason for not including an id column in the join table is that
AR automatically includes all columns from the join tables when
accessing rows using it. If the join table included a column called id,
its id would overwrite the id

ADVICE: Generating unique identifiers for later DB insertion
All,
I have an ActiveRecord object that I need to be able to uniquely
identify _before_ I actually save the object (I may not end up saving
the object based on conditions). This is because I want to use the ID
in another context (a file name in the filesystem).
Depending on conditions, I may or may not need to do a lot of stuff
between the time that I generate the object ID and actually

What is has_many :through really buying you over HABTM?
So having just learned how to do has_many :through as opposed to HABTM,
and then, being concerned that I wouldn''t get it to work, I started
thinking about these two approaches.
It seems to me that the _only_ problem that the HM:T (has_many :through)
approach solves that HABTM doesn''t is the issue of the potential
collision of id columns between your join table and one of

Setup new data in the test database _after_ unit test runs
All,
I want to run automated unit tests as part of my build. I am building

into my test database that will act as fresh "system test" data for my
users to play with.

Verifying some understanding about manipulating DB data in before/after callbacks in RSpec
We had an after(:each) callback that looked like this:
PurchaseOrder.find(:all).each {|po|
DraftInvoice.find_all_by_po_number(po.po_number).each {|di| di.destroy}}
which we were hoping would reset some purchase order data in a certain way.
However, because we have "self.use_transactional_fixtures = true" set in
test_helper.rb, this code was never getting committed.

Security considerations with displaying uploaded HTML
I have an application where I am allowing users to upload (or refer the
app. to) arbritrary HTML that I am (currently) displaying in an IFRAME
on a page. The users will be authenticated so it''s not open to the
entire universe.
I was always uneasy with this, but after reading the security chapter of
AWDWR, I am even more concerned.
What kinds of applications do people have out there

AJAX/CSS issue (more UI focused)
All,
This isn''t strictly a problem or issue with RoR but I wondered if
someone might have some insight.
I have a DIV on a page which I am using to "preview" the contents of a
URL provided by the user. Basically, when the user clicks on a link, I
do an AJAX call to an action which uses Net::HTTP to request the URL in
question and then update the DIVs innerHTML attribute

Using <%= text_field %> within partials is problematic
