I'm having trouble creating an application in Rails. This application has two models, one to represent companies and the other to represent products. Each company sells zero or more products and I'm looking to capture this relationship in the model. Here's what I've got so far: I created the models by running the generator: script/gen...
I have a set of Cucumber features that are successfully running on a Mac OS X 10.5 machine and a Windows XP machine. I tried running them on a Mac OS X 10.4 machine today and Cucumber can't find any of the ActionController::IntegrationTest methods on the Cucumber::Rails::World. I am receiving the following error when trying to send a ge...
I have been working with Ruby on Rails for over a year now and have been offered some development work with Python. I would like know if development with Python is as enjoyable as Ruby in terms of the clarity and ease of use. And how well is Python suited for Web development.

Just looking at http://github.com/mojombo/grit Curious, if grit is on a web server, and the git repositories are on another, will this still work or it HAS to be on the same server? Or does it use remoting somehow? ...

Now, what if you want to count the number of paragraphs in a Script *without having a script_id key in the paragraph model ?* class Script ha...
Hi, Can anyone confirm what config exactly is required to make the one time password (persistence_token) work? From what I can work out so far it is the following, however this isn't working for me so I must be wrong: pass an additional URL parameter of "user_credentials=xxxxpersistence_tokenxxxx" question - are there any other URL p...
From a model that returns all the values from a table, how would I convert that to a hash of name value pairs {column_value => column_value} e.g. [{:id => 1, :name => 'first'}, {:id => 2, :name => 'second'}, {:id => 3, :name => 'third'}] to (specifying :id and :name) {'first' => 1, 'second' => 2, 'third' => 3} ...
I have several models with a date attribute and for each model I'd like to validate these dates against a given range. A basic example would be: validates_inclusion_of :dated_on, :in => Date.new(2000,1,1)..Date(2020,1,1) Ideally I'd like to evaluate the date range at runtime, using a similar approach as named_scope uses, e.g: valid...
This is happening in an after_save method in one of my models, PlayerAction. I didn't change any code during the upgrade (famous last words). It appears to be happening on the following line: if self.action_type.id == 1 The PlayerAction model has a belongs_to :action_type Changing action_type.id to action_type_id fixed that problem...

I can't figure out why rails has_one :through associations don't accept assignments. Here is the error: >> u = User.new => #<User id: nil, created_at: nil, updated_at: nil> >> u.primary_account => nil >> u.primary_account = Account.new NoMethodError: undefined method `update_attributes' for #<Class:0x1035ce5f0> from /Library/Ruby/Ge...
So we've got a legacy system that tracks places with IDs like "Europe/France/Paris", and I'm building a Rails facade to turn this into URLs like http:// foobar/places/Europe/France/Paris. This requirement is not negotiable, the number of possible levels in unlimited, and we can't escape the slashes. Setting up routes.rb for http://foob...
I am in the middle of developing an enterprise application using RoR (first time for us to build an enterprise app on RoR instead of Java), and while we do not have that much problem of obscuring the source code, I was still wondering if this was possible.
