Where to place custom classes?
Hi all,
I am writing a simple shopping cart which will consist of a single
class. There will be no DB table for carts so I do not want to make my
Cart a model. But where do I place my Cart class so that I can access
it in my controllers?
I want to be able do do things like this (for instance in a shop
controller):
def add_to_cart
@session[''cart''].add(article_id, amount)

Multilingual Validation Messages
Hi all,
I have a mutilingual app and want to customize the validation error
messasges. I cannot override them as I need them in more than one
language, so I have done the following:
validates_presence_of :some_attr, :message => _(''should not be blank'')
I am using gettext to translate the message.
This works in development mode, but not in production, even after a

Hallo,
gibt es da Jemanden der mir den folgenden Text vielleicht ein bischen besser

Re: VFS calls after disconnect
Hello,
Below is the sample code almost similar to the one in Samba Developers's
guide. I tested it with a win2k client for samba 3.0.2a on FreeBSD.
When the example_connect is called the second time by the same client
handle->data is null.
The test can be reproduced as follows-
1) search for the computer from windows explorer. Access the vfs share and
create directory or perform any other

RE: Prototype: correct useage of onCompletewithAjax.PeriodicalUpdater
The only call that PeriodicalUpdater will make periodically to you is
the insertion call.
I think of onComplete as being ''I''ve done everything I was going to do'',
which for Updater is right after it''s done a single update, but for
PeriodicalUpdater, it''s after it''s finished all of its updates, so
you''ll only get it once for any call

RE: Prototype: correct useage of onComplete withAjax.PeriodicalUpdater
>From a quick look at the source code, it looks like onComplete is only
called when the whole thing is done - in the case of Updater, right
after the update, in the case of PeriodicalUpdater, right after it has
been stopped.
It looks like you need to pass your callback method as an ''insertion''
method in the options. This takes two parameters, the first will
probably be the

Positioning of axis titles
Hi,
I have created a plot using filled.contour() and have the problem that
one of the axis titles and an axis label are overlapping. I have tried
changing par()$mgp (with, e.g. par(mgp=c(4,1,0)) ), but this just
makes the title go off the screen. I can't work out how to make the
plot take up less space in the window, so I can hopefully change mgp
and sort the problem. Is changing mgp the only

The RoR equivalent of out.write() in JSP?
All,
In JSP, I can output strings in the Web page by either
<%= foo %> //foo is a string or returns a string
or
<% out.write("test") %> //write directly to the output stream.
What is the method of "writing to the output stream" in RoR? Basically,
what is the equivalent of out.write()?
I have an if then statement that I want to put around a call to

Associating with different classes
Dear Railers,
I am toying with a new project and have a schema design question.
I have a tree-like node structure. Each of the nodes will be
associated with a single object. This associated object can be of a
variety of types.
I represent the tree through a Node class which acts_as_tree. Now
imagine three other classes--Animals, Fruits and Vegetables. Each
node will have an association

RE: Why class InstanceTag is defined at 4 different places inRails
In Ruby you can add and modify existing classes at will simply by
reopening it. The 4 files you mention add functionalities to the
InstanceTag class. This is not a redefinition. The best part is that you
can do the same ! An easy way to overwrite an existing method or to add
new ones is to create a file under you rails application lib directory
and put in it the replacement you want to make:

Session and flash now working in IE6
Hi all,
I noticed that my sessions and flashes are not working in IE6 (no
problem with safari or firefox). I did a <%= debug session %> and
indeed IE6 is showing session[:new_session] to be true all the time.
This means a new session is created for every request.
An old version of the same application is running on the same server
under a different subdomain. In this sessions are

Proposal for UTF8 vs performance tip.
Avoid UTF8 processing if you don't need it and have extra speed
Many often used utilities are much slower with UTF-8 processing.
If you want extra speed and do not need UTF-8 processing, disable it using
export LANG=C
export LC_ALL=C (not needed if LC_ALL was not set)
compare
time grep -i -c some_string some_large files
with
LANG=en_US.UTF-8
and same with
LANG=C

Problem getting "extract" from RDig
Hi All,
I have to have a site wide search for my current application. By search
I mean I have to search the static and the dynamic contents from the
database. I have been searching on this for a while on the net and RDig
seems to be a apt solution. While using it I have encountered a few
problems. I know these might be very basic issues but I have not been
able to figure out what is wrong with
