I have some code that is using SyncEnumerator. As you can see here, SyncEnumerator requires generator.rb. To include this, the developer of this plugin has require 'generator'. This worked on my previous Rails installation but is not working since I upgraded OS X and reinstalled Rails. Now when I try to install my gems, I get: Macint...

I'm running mongrel on 3001 port (tried in both cucumber and test environments) and access it from cucumber via celerity. One of my tests looks following: create item 1 item exists do smth with item it w...
Are there any cases in which Rails overwrites controller instance variables on a render :partial call performed in a template? For example, let's say we have: controller def my_action @widget = Widget.find(params[:id]) end view my_action.html.erb Hi there. <%= render :partial => 'my_helper' %> That's it, that's all. view _my_he...
I'm just starting out with Ruby/Rails and am wondering what Rails developers use to provide reports and/or charts on Rails sites. In ASP.NET I use the tools from DevExpress but I don't know enough about the Rails ecosystem to know what is available. Any insight would be appreciated. ...

Wow crazy title! But here's the problem. In efforts to dry up my school website management system application, I've made a module of my application (FileSet) restful and placed it in one place. Previously FileSet was used in the general website system, and also in a kids learning area system. They both behaved exactly the same except for...
I think that acts_as_rateable seems to be quite obsolete and doesn't support AJAX. I'm looking for a simple "5 star" rating system: is there any plugin or tutorial that can help? ...
I have a FinancialDocument#document_type model attribute. I'd like to let the user select the document type from an HTML select menu populated by an Array of Strings... doctypes = [ 'Invoice', 'Packing slip', 'Other' ] For each option, the displayed label and returned value would be identical. I looked at the select and collection_se...

How do I create a module that when included in a model will automatically add some relationships and named_scopes? Here's what I've got right now: module Resource has_many(:permissions) named_scope( :acl_check, lambda do |user_id, method| { :include => :permission, :conditions => [ ["permissions.user_id=...
I'm going to be implementing a Web app using Rails with MySQL running on a small CentOS VPS. (Small server, limited user base to start out.) It's going to store a lot of text, sort of like a blog. I'd like to offer strong search options -- parens, AND, OR, exact phrase. The other piece of it is that the data is private, so using Google ...
I'm new to rails so I apologize for my ignorance. I'm setting a constant in a class outside of a method: PARAM = { #... => ... 'field' => escape('somethingwith/slashes') } and get a NoMethodError: undefined method 'escape' I tried Rack::Utils::escape and Rack::Utils.escape instead, but both don't work. Thanks in advance....
I am playing with the scaffold feature of rails in Netbeans 6.5. Right click->Generate gives me a menu that allows me to create the scaffold but asks for "attribute pairs". I have some tables with quite a few columns and would rather have the scaffolded pages include them all instead of specifying each one individually. Does anyone know...

I have a polymorphic relationship in Rails, but in one particular instance of use, I'd only like to retrieve records for a specific class. What's the best approach to do this? ...
Hi, I have an issue with Ruby on Rails. I have several model classes that inherit from the same class in order to have some generic behaviour. The parent class is called CachedElement. One of the child is called Outcome. I want an other model, called Flow to belong to any child of CachedElement. Hence Flow has a polymorphic attributes...
I'm attempting to create a simple web application for some personal development, but I've run into an obstacle, which I'm hoping others will find trivial. I have working classes created, but I'm not sure how define their relationships, or whether their models are even appropriate. For the sake of argument, I have the following classes a...
