I have a list of tasks (name, starts_at) and I'm trying to display them in a daily view (just like iCal). def todays_tasks(day) Task.find(:all, :conditions => ["starts_at between ? and ?", day.beginning, day.ending] end I can't figure out how to convert Time.now such as "2009-04-12 10:00:00" into the beginning (and end) of the da...
Rails Nested Object Form *_attributes problem
I'm using Rails 2.3.2, and trying to get a nested object form to work properly. I've narrowed my problem to the issue that Rails is not setting my nested form elements with the *_attributes required to initiate the accepts_nested_attributes_for processing. My model code is: class Person < Party has_one :name, :class_name => "PersonN...
Rails plugin to run migrations on startup?
Is there a plugin available to have Rails run through a db:migrate on startup? I'm looking for a solution that doesn't involve calling out to the Rake task via the shell; so, no "system('rake db:migrate')". I can readily write my own plugin to do this, but figured it would be better to use/improve an existing migrate-on-init plugin if ...
Rails Active Record find(:all, :order => ) issue.
I seem to be unable to use :order_by for more than one column at a time. For example, I have a "Show" model with date and attending columns. If I run the following code: @shows = Show.find(:all, :order => "date") I get the following results: [#<Show id: 7, date: "2009-04-18", attending: 2>, #<Show id: 1, date: "2009-04-18", atte...

Rails (or maybe SQL): Finding and deleting duplicate AR objects.
ActiveRecord objects of the class 'Location' (representing the db-table Locations) have the attributes 'url', 'lat' (latitude) and 'lng' (longitude). Lat-lng-combinations on this model should be unique. The problem is, that there are a lot of Location-objects in the database having duplicate lat-lng-combinations. I need help in doing ...
Rails' stale? method for sitemap always returns HTTP 200
My Ruby on Rails application uses the following controller code to generate a sitemap.xml file: class SitemapController < ApplicationController layout nil def index headers['Content-Type'] = 'application/xml' last_post = Post.last if stale?(:etag => last_post, :last_modified => last_post.updated_at.utc) respond_to...
Turning off auto-complete for text fields in Firefox
Am supposed to be learning French at the moment, but rather than learning any vocab, I've been mucking around with a rails app that tests vocab - so it displays a word, and I have to type its translation. Unfortunately, Firefox remembers everything I've already type there, so which diminishes its usefulness somewhat. Is it possible, th...
Dynamically construct RESTful route using Rails
I'm trying to write a helper method that accepts the name of a plural resource and returns a corresponding link. The essence of the method is: def get_link(resource) link_to "#{resource.capitalize}", resource_path end Clearly the resource_path part above doesn't work. What I'd like is to be able to pass foos to get foos_path and bar...
How can I improve this Rails code?
I'm writing a little browser game as a project to learn RoR with and I'm quite new to it. This is a little method that's called regularly by a cronjob. I'm guessing there should be some way of adding elements to the potions array and then doing a bulk save at the end, I'm also not liking hitting the db each time in the loop to get the ...

Gem Loading Error, installed from Github
Update: This gem DOES install with sudo rake gems:install. The problem is with loading. For instance, when I run script/console, it throws: no such file to load -- outoftime-noaa ...

Constants set in environment.rb disappear in development mode
Someone who understands how rails caching works can really help me out here. Here's the code, nested inside of the Rails::Initializer.run block: config.after_initialize do SomeClass.const_set 'SOME_CONST', 'SOME_VAL' end Now if I run script/server and make a request, everything is dandy. However, on the second request to my Rails ap...

The label form helper only takes a form field as a parameter, but in this case I have multiple radio buttons for a single form field. The o...
Rails validation and 'fieldWithErrors' wrapping select tags
Is it normal behaviour to not get the <div class="fieldWithErrors"> wrapped arround select tags that have validation errors? I personally see no reason why the select tags should be treated differently than other form tags (input, textarea). I do get the error in error_messages_for and error_message_on methods for that field. PS. I hav...
