validation problems
Hi, there.
I have two validations in the model:
validates_numericality_of :value, :only_integer=>true,
:allow_blank=>true
validates_size_of :value, :is=>9, :message=>"must be 5-digit number",
:if=>Proc.new{|u| u.value.is_a?(Numeric)}
They work as expected except when the :value is character/string like
"a" "abc", the second validation will also output

Setter that converts a float attribute to integer
Hi,
I have some problems with an application where I''m using custom
accessors to do currency conversions. In my model, I have a price
attribute in the database that stores the value in cents, to avoid
future problems with float arithmetic and round. But at the views, I
would like to show the price in euros, with decimal for the cents. So
I defined a new attribute called price_in_euros,

newbie validation
hi there. Here is the simple scenario:
My active record connects to a table that contains an integer field.
My form contains a text box that allows me to enter a value to get
updated to the integer field.
If anything gets entered that is anything other than a POSITIVE INTEGER,
I want to display an error.
I have noticed that if I create a new active record like

FW: flow control
Hi all,
I need a little help with flow control in R. What I'd like to do is to
advance a for loop by changing its counter. However, what seems obvious
to me does not yield the proper results. An example of my problem is
for (i in seq(1, some_number, some_increment)){
<some stuff>
if (some_condition == T) i <- i + 2; #want to advance the loop
by 2
}

how do I validate currency format if I am storing in cents?
Hi all -
To avoid floating point issues, I''ve decided to store monetary values in
cents in the database. However, the user will enter these in dollars
and cents. Two questions:
1) How do I do the validation for the currency format? It looks like
ActiveRecord truncates the cents since it thinks the field type is a
Fixnum. Am I forced to do validation in the controller?
2) Where

ActiveRecord does not close database connections?
I have an application that creates quite a few threads. I keep getting
the "mysql too many connections" error.
ActiveRecord does not close the connection once a thread had died out.
To make things worse mysql has a wait_timeout variable that would
basically kill off these connections for me, but there is a bug and I
can not change the value of it. I have tried at least 10 different

validates_numericality_of, :allow_nil => true?
Is there a way to use validates_numericality_of and still allow null
values?
I have a model with some optional values that can be nil, but if they''re
present, they must be numbers. Will I need to construct a custom
valiation for this, or is there some method built in? Seems like it
would be a common enough need.

validates_numericality_of positive integer
Hi,
What is the simplest way to validate a positive integer?
validates_numericality_of :foo, :integer_only => true
how do I add the positive part? Do I need another validation statement
for pattern matching or do I have to write a validate() funciton for
my model?
Thanks,
