Is there a shortcut for giving a limit and order when accessing a has_many relation in an ActiveRecord model? For example, here's what I'd like to express: @user.posts(:limit => 5, :order => "title") As opposed to the longer version: Post.find(:all, :limit => 5, :order => "title", :conditions => ['user_id = ?', @user.id]) I know y...
web2py to is a Python framework but shares the "convention over configuration" design that Ruby on Rails has. On the plus side it packages a lot more functionality with its s standard distribution and we claim it is faster and easier to use. Has any Rails user tried it? What is your impression? No rants please. Just technical comments...
Using Morph Labs' Appspace to deploy a site means no automated way to redirect 'myapp.com' to 'www.myapp.com' (and no access to .htacess). Is there an in-rails way to do this? Would I need a plugin like subdomain-fu? More specifically, I'm trying to do something like: 'myapp.com' => 'www.myapp.com' 'myapp.com/session/new' => 'www.mya...

Since we have a number of windows applications we have used samba in the past, but as we build pure linux apps I would like to do this the best possible way. We are expecting large amounts of data, so would need to sca...
What is the best way to set default value in ActiveRecord? I see a post from Pratik that describes an ugly, complicated chunk of code: http://m.onkey.org/2007/7/24/how-to-set-default-values-in-your-model class Item < ActiveRecord::Base def initialize_with_defaults(attrs = nil, &block) initialize_without_defaults(attrs) do ...

In my application, a user has_many tickets. Unfortunately, the tickets table does not have a user_id: it has a user_login (it is a legacy database). I am going to change that someday, but for now this change would have too many implications. So how can I build a "user has_many :tickets" association through the login column? I tried t...

Hi folks, I know this is probably on the Internet somewhere but I can't find the answer here on Stackoverflow so I thought I may boost up the knowledge base here a little. I'm a newbie to Ruby and Rails but my company is getting pretty invested in it so I'm trying to get to know it in a little more detail. It's been difficult for me t...
I may be barking up the wrong tree... However, what I have is a MySQL server that accepts connections only from a client with a valid SSL cert (see this link). This works great for example with Rails. I have my database on one server, and a Rails app that connects using the client certificate. Maybe not the fastest, but it works. The co...

I've been attempting to hook a Rails application up to ActiveDirectory. I'll be synchronizing data about users between AD and a database, currently MySQL (but may turn into SQL Server or PostgreSQL). I've checked out activedirectory-ruby, and it looks really buggy (for a 1.0 release!?). It wraps Net::LDAP, so I tried using that instead,...
