rails - 2 buttoms on a FORM

then, in my FORM there are 2 buttoms :

first to select a file to upload buttom="Parcourir"
second to send the complete Form, buttom="ENVOYER"

"parcourir" is for to select a file to upload

but "ENVOYER" must validate the complete Form :
- file selected presence
- other fields validatation

if evrything is OK, i have to upload the file (and save it)
and update a Table

how can i do this ?

You could use javascript to change the target of your form when they click either button. This can get messy though. Each different form target can have it’s own validation.

I guess you want to diferenciate clicks to different submit buttons. I
did it like this:

<%= image_submit_tag('add_16.png', :name => "action_categories/new") %>

By specifiing name you can differenciate in controller which button was
selected.

params.each do |e|
  if e[0][0,7] == 'action_'
    ctrl, action = e[0][7,100].split('/')
    action ||= 'index'
    break
  end
end

The example shows which controller/action call when submit button is
pressed.

"parcourir" is for to select a file to upload

Isn't this button just going to come "for free" was part of the file
upload tag?
