Hola a todos, me gustaria saber de que forma puedo ejecutar el codigo
que tengo en una accion de forma automatica.
Me explico mejor:
Yo tengo un codigo que actualiza tablas de una base de datos con datos
de otra, eso lo tengo hecho en Ruby on Rails con una accion de una vista
pero me gustaria saber
def test
yield
end
test do
p "a"
end
i don`t know how yield function does in detail. why did i write yield
and then the p 'a' works? i know that it is a Proc object , but i
don`t know how it works. Is Proc do as a parameter?
test do
p "a"
end
and is this code which makes the output?
thanks

I don't think you can use rails' standard 'valtidates' methods, like
validates_presence_of, but you can add your own custom validate method
to your model:
def validate
self.errors.add
if you name each of your (game)set input fields something like "set[]"
then rails will parse the parameters as an array. This way you will
give you a params hash like:
{ 'match' => { 'sets' => ['1','3','7']} }
This means in your model you can define a virtual attribute called
'sets' like:
