Need for multiple acts_as_list
I have a model "Childmodel" that belongs_to two other models "Parent1"
and "Parent2". "Parent1" "has_many :childmodels, :order => :positionp1"
and "Parent2" "has_many :childmodels, :order => :positionp2". i.e. The
child is independently positioned within each of its parents.

Read Only Error Since 1.1?
Since I upgraded to 1.1, I am getting ''ActiveRecord::ReadOnlyRecord''
exceptions when trying to save a specific record.
I read up on ActiveRecord::Base.readonly? but I don''t think the condition
there (objects pulled in from a certain JOIN type) applies.
Here''s my code that is throwing the exception:

acts_as_habtm_list plugin
I''d like to announce acts_as_habtm_list plugin for rails.
acts_as_habtm_list is a Ruby on Rails plugin, that can manage ordered
lists through a join-table. It is providing almost the same Api as
acts_as_list. The position column has to be defined in the join table.

Rspec Caveman questions.
Hello!
I''m just a caveman with some caveman questions.
I''ve been parsing Rspec for quite a while, and I''m writing my first series

Preloading results in Ajax App
Hello Rails lovers!
I have a few general discussions that I have yet to find terribly
active. Perhaps all of the people busy on this front are...uh...busy on
this front.
So!
Ajax-only apps.
No degration.
Yes! Forget about degradation for a moment. Not willing to? Ok,
well...this question is for those who are willing...
Imagine developing an app that is one page - all actions render partials

facebooker, respond_to and firefox 3 beta5/pre
Hi there,
I have a controller that responds to fbml and html, with html at the
top.
In all browsers, this works as expected - When I''m hitting the
controller from my normal app, I get html. When I hit it inside
facebook, I get fbml.
However, with Firefox 3 hitting the normal app, I''m getting fbml for
some odd reason.
Am I crazy?

Using facebooker AND Haml/Sass
For anyone using both and encountering trouble with stylesheets
(specifically, the paths being incorrect in production mode)...
Removing facebooker solves the issue.
But I bet you don''t want to do that, eh? So, simply setting
ActionController::Base.asset_host = ''''
also works like butter.
I''m not 100% clear on why asset_host has anything to do with

Simulating onmouseleave and onmouseenter with Prototype
Hello.
I spent an hour or three chasing down a desired effect that mootools
implements, namely the simulation of onmouseleave and onmouseenter
events.
Why?
Lets say you have a Menu. A ul element that contains many li elements.
If you want to have a function (maybe an effect) fire when the mouse
moves outside of the ul, you are out of luck. Observe the mouseout
function like so:

ActsAsList specs
Hi,
How are people specifying models which act_as_list?
I''m thinking that it would be possible to check that acts_as_list
instance methods have been added to a class using something like this:

it "should act as a list" do
Page.ancestors.should be_include(ActiveRecord::Acts::List::InstanceMethods)

acts_as_list and single table inheritance
in a single table inheritance model, rails will automatically set the
scope for acts_as_list to the ''type'' field as well as any other scope
conditions we provide.
Is there a way to disable this? i want to use STI but I want
acts_as_list to disregard the class type when getting/setting
positions.
thanks
