Action form_for -> show

URL : /evaluations

I have made a form to select a specific item (a period)

class EvaluationsController < ApplicationController
  def index
    @periods = Period.all
  end

My form :

<% form_for XXXXX do %>
  <%= collection_select(:period, :period_id, @periods, :id, :fullname) %>
  <%= submit_tag("Valider") %>
<% end %>

I would like the form to go to /evaluations/3 when submited (if the selected period is 3).

When I go manually to /evaluations/3 it works like a charm but I really don't know how to write the form_for to go the right url by submitting the form.

Simple way

Submit period ID to process data, and then redirect to action, which handles evaluations/:id with :id as parameters. 

redirect_to <youraction>(:period => @id)

This should do the trick.

Not so simple way

If you want to change something dynamically on your page after data was submitted - call method and respond with javascript

respond_to do |format|
  format.js 
end

In javascript response you can put whatever you want - simple redirects or script, which will change page dynamically. It's up to you.

Hope it helps.

you need to use some javascript to update the action of the form

$('#period_period_id').change(function() {
  $('form').attr('action', '/evaluations/' + this.value);
})
