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

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

The true merit of non-memory based session stores
All, There is an assertion in AWDWR that the in-memory session store is "too simplistic." However, I find myself nudged in this direction by the need to keep a non-serializable model attribute available in my session and the relative pain of implementing either a custom serialization scheme for the model in question (or a custom caching mechanism so that I can store my attribute

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. So, I just

Addressing attribute of object specified by has_many fails
I have two model objects, Document and Images. Here are the relevant declarations: class Document < ActiveRecord::Base has_many :images class Image < ActiveRecord::Base belongs_to :document The database tables exist and foreign keys are set up correctly. In my controller, on an initial request, calling @document.images (nothing in it yet) is fine. However, after I attempt to

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.

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.

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 -- Posted via http://www.ruby-forum.com/.

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

Ruby server infrastructure evolution -> app. servers?
All, Just musing about this whole FastCGI thing (that I hadn''t even thought of since 1999 when looking at OpenMarket for a customer and even then it was "old"), and wondering when we might see projects/products that attempt to provide Ruby application services in a J2EE-like container. I see the Cerise project - any interesting information on that? I''m assuming

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 wrong with this initialize method (code example)?
Here is my class: class Document < ActiveRecord::Base public def initialize puts "Called initialize..." super.initialize end This generates the following error: You have a nil object when you didn''t expect it!

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

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
