Every time I use an asset tag helper, there is a parameter appended to the end of my file name. e.g. <input src="/images/search.gif?1213816620" type="image" /> From what I am reading, this appears to be a timestamp for caching purposes. It works in most cases, but I want to use image_path to embed a flash file. .swf file in public/images/flash e.g.

Ok so I have this route map.namespace :trades do |trades| trades.resources :buys, :path_prefix => ''/trades/:contract_id'' end I want the contract_id variable to filter a list of buys then I try to open this route http://localhost:3000/trades/1/buys I get a strange error: ActionController::RoutingError in Trades/buys#index Showing trades/buys/index.html.erb where line

Hello security gurus, yesterday, I mistakenly posted a question on the questions list about this article : http://www.securityfocus.com/bid/13676/info/ which talks about a form of DOS vulnerability. I was curious as to the possibility of FreeBSD 5.x being affected, and if anyone was working on this or not. Ted Mittelstaedt posted this possible patch based upon the OpenBSD patch : in

If I have a class, Asset, which has and belongs to many associated Asset objects, how do I do this? has_and_belongs_to_many :associated_assets, :class => "Asset", :foreign_key => ?????, :association_foreign_key => ????? Right now, my table has a :first_asset_id and a :second_asset_id, but I don''t see how the objects themselves are supposed to distinguish one from the

Hello, I've executed the following predict.coxph function to enable prediction for new variable values (error is included). *predict(cox_out,newdata=data.frame(Meter3.Value=100.001, Meter4.Value=200.001,Meter5.Value=300.001,Meter10.Value= 400.001,type="expected")) Error in model.frame.default(data = data.frame(Meter3.Value = 100.001, : variable lengths differ (found for

Hi, I''ve search for documentations on queries with Arel 2 but there is pretty nothing and all I''ve found is for Arel 1 so I''ve run into NoMethodError: undefined method `[]'' for #<Arel::SelectManager:0x00000003f1b820> errors with join syntax. My query is barely simple but involve nesting queries. I have 4 tables. Assets, Deposits, Orders and OrderLines

hey all In my schema, Lesson is many to many with Asset (through join table ''elements''), which are also many to many with Resource (through join table ''items''). This is all done with totally standard "has_many :through" - Lesson has_many :elements, :dependent => :destroy, :order => :position has_many :assets, :through => :elements,

I have a model Asset which has_and_belongs_to_many :tags. Tag has only one field, name. There is a table assets_tags which only has an asset_id and a tag_id. I can add a tag to one asset. If I try to add the same tag to another asset though (asset.tags << tag) I get this error: Mysql::Error: #23000Duplicate entry ''4'' for key 1: INSERT INTO assets_tags (`tag_id`, `id`,

I''m converting our app into restful rails. A couple of my classes (Resource and Asset) have a has_many relationship with each other - here''s the routes: map.resources :assets, :has_many=>[:resources] map.resources :resources, :has_many=>[:assets] I''m getting something weird in my view pages. When i go to /resources/4/assets it works. I go to the page

Hi, I've encountered a strange problem while using FreeBSD 6.0 for our local mirror (mirror.math.uni-bielefeld.de) and thus is providing access via ftp, http, rsync and cvsup (all local and remote). The system crashes periodically with a kernel panic (panic: sbdrop). The uptimes between two crashes are going from a few hours to a few weeks. The system is a i386, Intel Pentium 4 based with

I am trying to create a model that allows only unique assets to be added to a category. However, they could be added again to a different category. Finally, an asset can be shared across many categories. So my question is how do you check the uniqueness across a join table? This does not compile.... has_and_belongs_to_many :categories, :foreign_key => ''asset_id''

A model has 2 columns in its table asset_type_id asset_id the asset_type_id links directly to the table asset_types via a belongs_to asset_types contains a single column ''name'' method_missing in the model says when you call a method matching /^asset.*/ call the corresponding method substituting ''asset'' for the contents of asset_type.name (ie. the name in

I am going to be developing a Risk Assessment system for a secure environment whose database will double as an asset management system. Or at least the Risk Assessment stuff will be an outcropping of the asset management system. Has anyone had any experience with this or a similar project? This is my first attempt at a Rails project after spending a few weeks reading books and getting a general
