:include breaks has_many :order
It would appear that using :include on a model that has_many with an
:order on another model makes it so that the order is ignored. Is this
supposed to happen? Strikes me as odd behavior.
For example
class Farmer < ActiveRecord::Base
has_many :cows, :order => ''position''
end
class Cow < ActiveRecord::Base
acts_as_list :scope => :farmer
end

Single Table inheitance doesn''t show subclasses ?
Hi, I am a Rails noob.
Suppose you have:
---
class Animal < ActiveRecord::Base
end
class Mammal < Animal
end
class Cow < Mammal
end

I provide Animal,Mammal and Cow controllers with the scaffolding, just
to test and to fill up the Animal table. I can see the "type" column
getting it''s value set with the class name.
So far, soo good.
Now, since listing Animals

Letter Spacing
Hi All,
I've been trying to make some adjustments to the graphics in a paper I wrote some time ago, for which the comments have been
returned from the reviewers.
I always use R for publication graphics...I think it does the best job available, for the things I am interested in.
I could not get my graphics in R 181 to look the same as the old ones (completed 8 months ago),

polynomial predict with lme
Does lme prediction work correctly with poly() terms?
In the following simulated example, the predictions
are wildly off.
Or am I doing something daft?
Milk yield for five cows is measured weekly for 45 weeks.
Yield is simulated as cubic function of weekno + random
cow effect (on intercept) + residual error.
I want to recover an estimate of the fixed curve.

Nolinear mixed-effects models (nlme)
Hello,
I am trying to fit a nonlinear model of the form of:
A*x^b*exp(-c*x)
This represents a lactation curve. I have a bunch of cows, so I want
COW to be a random effect.
I have been trying the following code with very littel success:
> fm1 <- nlme(yield ~ A*(DIM^B)*(exp(-C*DIM)),
+ data = group,
+ fixed = A + B + C ~ 1,
+ start = c(A = 20, B =

Lattice graph help
Hi all
I hope you might help me with some aspects of producing a graph in lattice. There are three things I have struggling with and that is: 1. to separate the horizontal box rows from each other; 2. to change the colour of the horizontal and vertical strips to white; and 3. to place the axes labels on the left y axes and on the bottom x axes. I would really appreciate some help. I have put the

Isolating rails model specs from their implementation
I''m currently taking a Rails project management app I built when
learning Rails and adding specs to it. During the course of building
the app the requirement that project should be archiveable was added.
So a project is in one of two states active or archived.
This led to the creation of the following methods:
Project.active_projects
Project.archived_projects
@project.active?

mocking missing methods
Hi folks.
So I''m using mocha on a ruby project, and I really like it. One thing
I''ve noticed is that it can be a bit "surprising" when I''m mocking
methods that don''t exist on an object, and I think there''s an easyish fix.
At the moment, you use sheep = mock() to create a mock sheep. What I''d
like to do is something like sheep =

"they" synonym for "it"?
I''ve noticed that I phrase a lot of shared behaviours in plural, eg
describe "All payment_details views"
How about a "they" alias to "it" so you can write
describe "All payment_details views", :shared => true do
they "should have a card number field" do
# ...
end
end
WDYT?

ferret using UTF-8
Hey all,
I went through the docs in Ferret''s page, plus a quick search through
the email list (thread titles), and I couldn''t find any info on how to
have Ferret storing it''s data using UTF-8.
In the scenario I would use it, nothing''s being stored outside (like
external databases). So it''s just how Ferret would do it that I''m

AGI Delimiter in 1.6
Hi
I am currently using 1.2.x and 1.4.x behind OpenSER. One of the things
I do on INVITES is to re-authenticate the user from OpenSER. Then when
the INVITE gets passed to Asterisk I capture the AUTH to a variable in
the dialplan and pass to an AGI script. I am now trying to set the
same thing up in 1.6 However because the argument delimter in 1.6 has
changed from pipe to comma this breaks as the
