I am just getting into Grails having had some experience with Rails, and I am looking at creating an app where I have to primarily persist tree structures (and query them as well). Rails has several very useful acts_as helpers for representing domain objects as different data structures, such as acts_as_tree. From my initial reading it ...
I'm using Rails migrations to manage a database schema, and I'm creating a simple table where I'd like to use a non-integer value as the primary key (in particular, a string). To abstract away from my problem, let's say there's a table employees where employees are identified by an alphanumeric string, e.g. "134SNW". I've tried creating...

However, I can't find any documentation on setting up a a source besides SQL. The config file doesn't seem to indicate that the source can be anything ...
Hello, We're using EngineYard Cloud to deploy our Ruby on Rails application. We are running Rails v2.3.3. EngineYard Cloud deploys to AWS instances in a manner similar to Capistrano.

I can do sudo gem rdoc activerecord --no-ri and sudo gem rdoc actionpack --no-ri both of which give me good docs. But sudo gem rdoc rails --no-ri gives me pretty much nothing, as the Rails gem itself is really just a holder for the others. How can I generate the equivalent of http://api.rubyonrails.org/? ...

I'm not a Rails developer (currently) so please forgive my ignorance on this. One thing I've always liked about Rails is migrations and how it fills a need that's common across all languages and platforms. With that said, I am curious to understand what a certain scenario would result with the changes made in 2.1. Rails 2.1 and higher...
Hi, I'm trying to create a multi-level ajax form on my rails app that can add/remove fields associated with a new object in a form when a button is clicked. However, I need to have multiple levels to this form (i.e. if someone adds a "Meal" object, there must also be a button inside the created "Meal" form for "Add a food".) I follow...

I have a weird situation involving the need of a double inner join. I have tried the query I need, I just don't know how to make rails do it. The Data Account (has_many :sites) Site (habtm :users, belongs_to :account) User (habtm :sites) Ignore that they are habtm or whatever, I can make them habtm or has_many :through. I want to b...
I'm using the following technique to set a wild-card cookie for our domain: cookies['root_domain_flash_warning'] = { 'value' => 'mistakes have been made!', 'domain' => ".#{APP_DOMAIN}", 'expires' => 2.minutes.from_now } Which seems to work handily. Unfortunately I can't seem to look up anything but the value associated with the...
Hi, I made a rails app that generates HTML code for eBay product description. Currently my client copies the HTML code to the eBay site manually. I wonder if I can automate the process. Of course, I don't want to start from scratch. Is there any eBay API plugin for that? Thanks. Sam ...

I'm building a site that has user defined pages that are composed of a set of widgets. The widgets are fairly basic, similar to what you'd find in Blogger. Some widgets are for data collection/formatting presentation with basic structure (lists, tables) and others provide more complex functionality (blog, photo albums, etc) I want to a...
