I have a sequence of migrations in a rails app which includes the following steps: Create basic version of the 'user' model Create an instance of this model - there needs to be at least one initial user in my system so that you can log in and start using it Update the 'user' model to add a new field / column. Now I'm using "validates...
I've got a rails application where users have to log in. Therefore in order for the application to be usable, there must be one initial user in the system for the first person to log in with (they can then create subsequent users). Up to now I've used a migration to add a special user to the database. After asking this question, it se...
The RoR tutorials posit one model per table for the ORM to work. My DB schema has some 70 tables divided conceptually into 5 groups of functionality (eg, any given table lives in one and only one functional group, and relations between tables of different groups are minimised.) So: should I design a model per conceptual group, or should...
I'm trying to import an XML file via a web page in a Ruby on Rails application, the code ruby view code is as follows (I've removed HTML layout tags to make reading the code easier) <% form_for( :fmfile, :url => '/fmfiles', :html => { :method => :post, :name => 'Form_Import_DDR', :enctype => 'multipart/form-data' } ) do |f| %> <%= f.fil...
I read everywhere that business logic belongs in the models and not in controller but where is the limit? I am toying with a personnal accounting application. Account Entry Operation When creating an operation it is only valid if the corresponding entries are created and linked to accounts so that the operation is balanced for exempl...
I've created a learning application using Bort, which is a base app that includes Restful Authentication and RSpec. I've got it up and running and added a new object that requires users to be logged in before they can do anything(before_filter :login_required in the controller). [edit: I should also mention that the user has_many of th...
Whenever I run rspec tests for my Rails application it takes forever and a day of overhead before it actually starts running tests. Why is rspec so slow? Is there a way to speed up Rails' initial load or single out the part of my Rails app I need (e.g. ActiveRecord stuff only) so it doesn't load absolutely everything to run a few tests...

Does anybody here have positive experience of working with MS SQL Server 2005 from Rails 2.x? Our developers use Mac OS X, and our production runs on Linux. For legacy reasons we should use MS SQL Server 2005. We're using ruby-odbc and are running into various problems, too depressing to list here. I get an impression that we're doin...
In an effort to reduce code duplication in my little Rails app, I've been working on getting common code between my models into it's own separate module, so far so good. The model stuff is fairly easy, I just have to include the module at the beginning, e.g.: class Iso < Sale include Shared::TracksSerialNumberExtension include Shar...

So I'm working on a Rails app to get the feeling for the whole thing. I've got a Product model that's a standard ActiveRecord model. However, I also want to get some additional product info from Amazon ECS. So my complete model gets some of its info from the database and some from the web service. My question is, should I: Make two mod...
I'm looking at Rails development as a backend to a Flex application and am trying to figure out the communication layer between the Rails app and the Flash Player. All of the things I am finding suggest using SOAP web services to communicate. However, Flash supports AMF which is nice and fast (and native). Is there any way of communic...

Is there a way to restart the Rails app (e.g. when you've changed a plugin/config file) while Mongrel is running. Or alternatively quickly restart Mongrel. Mongrel gives these hints that you can but how do you do it? ** Signals ready. TERM => stop. USR2 => restart. INT => stop (no restart). ** Rails signals registered. HUP => reloa...
As popular as Ruby and Rails are, it seems like this problem would already be solved. JRuby and mod_rails are all fine and dandy, but why isn't there an Apache mod for just straight Ruby? ...
