Suggestion for improving value_to_boolean column conversion
Hi fantastic rails core developers.
Speaking of version 2.3.5:
I find it rather error_prone that values such that "some text" is
silently converted to false when stored in a boolean DB field.
Among other things it means that assign "some text" to boolean fields
on a model will not generate any validation messages (it will silently
be converted to false).
I think it is like

Does ActiveRecord have support for "Boolean" columns?
Hey all --
I''ve been using enumerable char(1)''s with ''y'' and ''n'' values for my
Boolean columns in Rails, but it strikes me there should be a better
way.
How do you setup columns that represent true/false-ness in your
schemas on Rails?
Wondering what kind of standard approaches there are other than me

actionmailler corrupting emails
Hi All,
I have a problem with actionmailer corrupting my html emails. It is
adding the character ''3D'' before any quotes (single or double) in my
source and smattering ''='' characters throughout as well. Very
strange. Here''s an example from one of the emails:

Reference classes and memory consumption
Dear All,
It seems that reference classes consume a lot of memory which became a problem for my rather extensive simulation.
I prepared a small example. An instance of this minimal class uses about 20K on disk.
rm(list=ls(all=TRUE));
MySmallClass = setRefClass("MySmallClass",
fields = list(
myField = "numeric"
),
methods = list(

Debian vs Ubuntu for a postgresql database + rails
I''m going to be getting a VPS at rimuhosting.com, and it''ll only run
postgresql and an app that uses AR/ActionSupport. I always use
FreeBSD, but in this case my options are limited to RHEL4, FC5, Debian
and Ubuntu. I figure Debian and Ubuntu are probably preferable...so
which one should I go with? This will not run an email, ftp, or web
server - just postgresql 8.1 plus a Ruby

How to call subset in a for loop?
Dear all,
I have a data frame 'myDf', in which one of the fields 'myField' can have
several possible values. To extract the observations for which it has value
"A", I can do:
subset(myDf, myField="A")
However, when I try to do this within a loop, it doesn't work, it returns
everything, and not a subset

ActiveRecord::ConnectionAdapters::Column value_to_boolean(value) does not return a boolean value.

About normality tests...
Hi all,
I have two very large samples of data (10000+ data points) and would
like to perform normality tests on it. I know that p < .05 means that
a data set is considered as not normal with any of the two tests. I am
also aware that large samples tend to lead more likely to normal
results (Andy Field, 2005).
I have a few questions to ensure that I am using them right.

improving ts object
Dear all,
Currently, a ts object behaves like an array, and it would be very useful to have a similar object, which would behave like a data.frame, i.e. it could be indexed, named, etc. like a data.frame. What would be the most efficient way to construct such an object? I have tried to make one on my own following the directions of class design from "S Programming" (2000) as a

Overriding new or create for a model
I have a model where I need to calculate one of the fields when I create
a new instance. It seems to me that I should do this in the model code
and that I should override the new and/or create methods.
Is this the right approach and, if so, how can I execute the existing
method but add on my calculation?
I want something like:

NOOB: Numeric only input...can it be done on client?
I was wondering if there''s a way to limit what a user is typing on the
keyboard to only valid numeric input. Is there a simple plugin or something
which would allow this? I guess with AJAX it could also be one. Has anyone
already solved this requirement? Thanks in advance.
