Or have a look at my validates_date_time plugin

http://svn.viney.net.nz/things/rails/plugins/validates_date_time

You’d need to add an extra regex to match ddmmyyy.

irb(main):001:0> str = “ddmmyyyy”
=> “ddmmyyyy”
irb(main):002:0> str.sub(/(…)(…)(…)/) {“#{$3}-#{$2}-#{$1}”}

The situation is when i create a person, in the form the user enter his
date of birth in “ddmmyyyy” format and name, adress etc… Then i call
in my controler an action called “create_stagiaire”

which is :

def create_stagiaire
@stagiaire = Stagiaire.new(params[:stagiaire])
if @stagiaire.save
flash[:notice] = ‘Stagiaire was successfully created.’
redirect_to :action => ‘list’
else
render :action => ‘new’
end
end

By using ur code is the final code supposed to be something like that? (
the column name for the date of birth is : dob )

def create_person

string = params[:dob]
Ddn.new(*string.scan(/(\d{2})(\d{2})(\d{4})/).flatten.reverse.map(&:to_i))
@stagiaire = Stagiaire.new(params[:stagiaire],ddn)
if @stagiaire.save
  flash[:notice] = 'Stagiaire was successfully created.'
  redirect_to :action => 'list'
else
  render :action => 'new'
end

end

? sorry me soo noob in ror :(. I bought the book and done several tuto,
but never done such things.
