Is this a legitimate use of Rails' Single Table Inheritance?
I've just been reading Chad Fowler's blog post about 20 Rails Development No-Nos. On Single Table Inheritance he comments: The storage of a column called “type” which holds a class name is a pretty good indicator that something fishy is going on. It’s fishy but not always bad. I think, though, that any time you use it you should ask ...
ActiveScaffold - Specifying Conditions in Embedded Scaffold
Hi, I have a Project model and a TaskType model. Association between the two occurs through a ProjectTaskType model (backed by a link/join table in the DB with foreign keys to both Projects and TaskTypes). A Project has_many TaskTypes :through ProjectTaskType, and a TaskTypes has_many Projects :through ProjectTaskType. I have a...
testing helpers with 'haml_tag'
module FooHelper def foo haml_tag(:div) do haml_content("bar") end end end When I test this I get: NoMethodError: undefined method `haml_tag' This code is perfectly valid and works in a development/production environment.

Continuous Integration Advice?
I'm working on setting up a Continuous Integration server (using Integrity) for my Rails app, and I'd like advice: Do most folks set up CI to build and test their app on every push to their central SCM repository, or only when pushing to their staging branch? I'll use the CI server to automatically run flay, flog, reek, and rcov -- are...
Correctly storing dates with TimeZone in MySQL DB for a Rails application
I'm looking at converting our Rails 2.3 application to correctly handle time zones (at the moment everything is in UTC which isn't right, but is convenient!). I have these settings in environment.rb: config.active_record.default_timezone = :utc config.time_zone = "UTC" Going forward, on each request in our app I plan on making the fo...

named_scope is creating new objects if I use it with a :join
Disclaimer: My original exposure to Ruby on Rails was literally years ago, and a great many things are new to me now that I'm picking it back up. One of these things is named scopes. They seem great, but I'm not getting the result I expect. Here's a for-instance: class User has_many logs named_scope :logged_in, :joins => ['logs'...

Tables representing an enumerated list of codes in Rails?
I've looked through similar questions but I'm still a little perplexed about something that seems to be a simple case in Rails. Let's say I have a model class called Employee. One attribute of an employee is their security_clearance, which is a string that can be None, Some, or Full. No other values are valid. In other applications I'd ...

Rails: How do I save a string representation back into a model?
I have an Employee model that has a SecurityClearanceLevel. When you make a new employee, you're asked to set a SecurityClearanceLevel by choosing from a <select> list. The problem is that when I save the object, it's a string, not a SecurityClearanceLevel, so the save fails. Where do I take care of this kind of back-and-forth conversio...
Model Name Conflict
I have a model by the name Filter but due to the changes in reorganizing the filters from 2.0.3, it is conflicting with the ActionController::Filters::Filter (class) In my filters_controller.rb when I try to find the filter Filter.find(:id) as rails is infering the ActionController::Filters::Filter class rather than my model clas...

RadRails trial expired - any free options for Rails in Eclipse?

And is there any other - free - option for Eclipse? (I tried "Ruby RDT" but it doesn't offer any Rails support, just basic Ruby editing.) ...
Filtering ActiveRecord queries in rails
I'm used to Django where you can run multiple filter methods on querysets, ie Item.all.filter(foo="bar").filter(something="else"). The however this is not so easy to do in Rails. Item.find(:all, :conditions => ["foo = :foo", { :foo = bar }]) returns an array meaning this will not work: Item.find(:all, :conditions => ["foo = :foo", { :...
