Hi, I want to know how I can pass the following parameters ...
I have
faculdade: id, name
curso : id, faculdade_id
and the following code
#view
<%= select(:curso, :faculdade_id , Faculdade.find(:all).collect {|c|
[c.nome, c.id] }) %> </p>
<th><a href="curso/lista_faculdade?teste="+:faculdade_id>
Preço
do Curso</a> </th>
controller
def lista_faculdade
teste = params[:teste]
@faculdade_teste = Curso.find(:all).select do |student|
student.faculdade_id = teste
end
if I try to do it manually (with /cursos/lista_faculdade?teste=3 for
example it works
all I need to know is how to pas the parameter from the select to the
href link
Thanks in advance! =*

Yes, look into observe_field in the API, and you could easily write a small RJS template which replaced the link with one with the appropriately inserted value. Julian. Learn Ruby on Rails!

Just also of interest, is this:> def lista_faculdade > teste = params[:teste] > @faculdade_teste = Curso.find(:all).select do |student| > student.faculdade_id = teste > endYou should probably be using Curso.find_by_faculdade_id(teste) as this will put the searching at the database level (this is what databases are good at), and not force Rails to load the entire dataset into memory to only then filter it back using Ruby''s select iterator.
