Rails: Two separate create forms..how to keep them separate? - ruby-on-rails-3

Question

In Rails 3.0 I have the standard 'new' form that creates a new record, in this case a patient. It works fine and the validations / error showing also work fine.
The client now wants the form in Spanish.
So, I did this:
Created a new html doc called "newspanish" (Cut / paste code from "patients/new")
Created a new partial called "_form_newspanish" and referenced it where the "form" partial is in "newspanish" (Cut / paste code from view "patients/_form")
Created a controller action in "patients" called "newspanish" and cut/pasted exact code from the "new" action.
I left the "create" action untouched.
Added match "patients/newspanish" to routes.
Translated the english parts to spanish in views/newspanish and views/_form_newspanish. Just the stuff that users read on the page, of course...not the rails code.
And, it works, for perfect submissions.
For submissions that fail validation (like putting 3 digits in as a phone number), the page reverts to the view "patients/new" and shows the errors above the form... in English, of course, because patients/new is in English.
Of course, I want it to revert to "views/newspanish" and also show custom verbage in the validations errors (spanish).
Any thoughts on how I can get the patients/newspanish view to load when error validation it tripped?
Here's my code for "_form_newspanish"
<%= form_for(#patient) do |f| %>
<% if #patient.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#patient.errors.count, "error") %> prohibited this subscriber from being saved:</h2>
<ul>
<% #patient.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<p><label for="mobile">Número de teléfono celular o móvil*</label>: <%= f.text_field :mobile %></p>
<br />
<%= f.submit "Inscribirme" %>
</div>
<% end %>
And controller... patients/newspanish
def newspanish
#patient = Patient.new
respond_to do |format|
format.html # new.html.erb
format.xml { render :xml => #patient }
end
end

Answer 1

<%= form_for(#patient) do |f| %>
is creating a form whose url is submits to is "/patients" which matches to patients_controller, create action.
That create action probably has a line that says (in my pseudo code)
if #patient.save
redirect to somewhere
else
render :new
end
That line "render :new" is showing the "patients/new" view.
So what you have to figure out is to either
1) detect in patients_controller # create how to tell if its spanish, and render "newspanish"
OR
2) change <%= form_for(#patient) do |f| %> to submit to a new url that just handles the spanish version, and make a new controller or action that just handles the spanish form (and renders "newspanish" if the #patient doesn't save
For #2, you could manually change where the form submits to with
<%= form_for(#patient), :url => spanish_patients_path do |f| %>
and in your routes create
post "patients/spanish" => "patients#create_in_spanish"
and add def create_in_spanish to your patients controller
