Hi all,

Rails 2.1 seems to converts the following parameters  
{‘birth(1i)’=‘1990’, ‘birth(2i)’=\>‘2’, ‘birth(3i)’=\>‘31’}  
into date ‘1990-03-02’ automatically.  
Is it able to inhibit this convertion?

Does anyone help me?  
The following is an example to be converted invalid  
date automatically (2008-02-31 -\> 2008-03-02).  
I want to stop this convertion.

$ ruby script/generate scaffold person name:string birth:date  
$ rake db:migrate  
$ ruby script/console

> > hash = {“name”=\>“Foo”, “birth(1i)”=\>“2008”, “birth(2i)”=\>“2”, “birth(3i)”=\>“31”}  
> > person = Person.new(hash)  
> > p person  
> > #\<Person id: nil, name: “Foo”, birth: “2008-03-02”, created\_at: nil,  
> > updated\_at: nil\>

There is no February 31, 2008 (2008-02-31). This year, 2008, is a leap  
year so there WAS a February 29, 2008. The next day would be March 1,  
2008 (February 30, 2008 by your calendar) and the day after March 2,  
2008 (2008-03-02) or February 31, 2008 on your calendar. So Rails/Ruby  
“fixed” it for you. If you don’t want that behaviour, use strings for  
you special two extra days in February. (What are you gong to do next  
year without February 29, 2009? 🙂
