why validation on server side
hi,
i have noticed that the validations in RoR happen at server side
mostly what sites do is using javascript they validate user information
there...
whats the point of doing it at the server side
is it that loading of javascript file in a browser makes a response to
client slow
and validation at server side offsets that....?????
any sugeestions????
is it that i am missing something as

Struts vs RoR
hi,
I recently attended one of the ruby meetings that we have in my city.

but still the performance of RoR is not at par with J2EE others....
he meant that though google,amazon working o it they will not bring it as
front applications only parts
the reason ruby is slow in comparison to other languages....

Decimal datatype and trailing zeros
Hello
I''ve encountered a little problem with zeros using the decimal data
type
Specifying a scale of 3 and inserting a number with 3 zeros after the
point (for example 12345.000) it gets correctly stored in the
database, but rails insists to show me the number only with the first
zero after the point (12345.0)
There is a way to tell rails to not truncate at the first zero?

send_file - PDF
Hi-
I''d like to load a PDF file into a page, in my controller:
send_file "/path to/my.pdf", :disposition => "inline"
However, instead of rendering inline, it asks to download the file.
How can I display the contents without downloading?
Thanks!

number_to_currency not working since 2.1.1
Back in 2.1.1 everything was sweet:
Loading development environment (Rails 2.3.3)
>> include ActionView::Helpers::NumberHelper
=> Object
>> number_to_currency(12.3)
>> "$12.30"
Then I upgraded to 2.3.2 and:

Difference between nginx and mongrel
Hi,
I could never find out what''s the difference between nginx and
mongrel. All my searches say "nginx is a HTTP server ..." and "Mongrel
is a fast HTTP library and server for Ruby....". For me they both mean
"...HTTP server...".
I kept up with this question for some time till I came across this

file_field doesnt work inside form_remote_for
When I do file_field within a form_for things are fine... but within a
form_remote_for, with nothing else changed, I find that the params
does not even have the element document[uploaded_file] even though it
is definitely present in the HTML source in the form. Obviously the
file upload fails.
Am I missing something? Or has someone else faced this? Or is this a
known bug?

Factory_girl association with specific values
Hope this should be simple: I have a User model and a Role model. Factories
for each.
When I create a User using FG, I want to assign a specific role. Cant seem
to figure out how to do this, getting errors like: uninitialized constant
SysadminRole for doing things this way:
Factory.define :user do |u|
u.practice_id { |a| a.association(:practice).id }
u.password ''password1''

Updatable "datagrid" with ajax support? Is there any code/approach I can leverage?
Hi,
I want to have a page in my Ruby on Rails application that is like a
dynamic / updateable data grid. Like a matrix or spreadsheet segment
(x rows, y columns) which one can click in any of the cells and make
an update, which triggers some AJAX code to fire off the update, and
then the responses come back and update whatever else needs updating
based on this change.
Is there a prototype
