using two controllers in one view - ruby-on-rails

Question

I'm making contact form on simple site using ruby on rails. Problem is following. I have main controller StaticPages that makes plain html with header and footer. Now i made controller Contacts that displays view with simple contact form on separate url. When i try to add this form to my contact page from StaticPages it doesn't work. i don't know how to tell rails that this form should find method not from StaticPages controller but from Contacts controller.
Here is my code:
Contacts controller
class ContactsController < ApplicationController
def new
#contact = Contact.new
end
def create
#contact = Contact.new(params[:contact])
#contact.request = request
if #contact.deliver
flash.now[:notice] = 'Thanks!'
else
flash.now[:error] = 'Error!'
render :new
end
end
end
StaticPages controller
class StaticPagesController < ApplicationController
def home
end
def about_us
end
def contact_us
end
end
and here is the form i need to work on StaticPage contact_us
<div align="center">
<h3>Send us message</h3>
<%= simple_form_for #contact, :html => {:class => 'form-horizontal' } do |f| %>
<%= f.input :name, :required => true %>
<%= f.input :email, :required => true %>
<%= f.input :message, :as => :text, :required => true %>
<div class= "hidden">
<%= f.input :nickname, :hint => 'Leave this field blank!' %>
</div>
<div>
</br>
<%= f.button :submit, 'Send', :class=> "btn btn-primary" %>
</div>
<% end %>
</div>
I guess I need to tell rails that this form should be looking for particular controller, but I don't know how.
Please help.

Answer 1

This isn't quite what you're looking for but it should work the way you want, you should have a contacts_helper.rb, that should look like this
module ContactsHelper
def contact_us
#contact = Contact.new
end
end
In your partial you'll want
<%= simple_form_for contact_us, :html => {:class => 'form-horizontal' } do |f| %>
And finally you need to include your helper, in application_controller.rb
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
...
include ContactsHelper
...
end

One easy option would be to have the StaticPages contact_us action redirect_to new_contact_url (assuming that form lives at app/views/contacts/new.html.erb)
Alternatively, you could put the form in app/views/shared/_new_contact.html.erb, then put in #contact = Contact.new in your contact_us action, and have the contact_us template render partial: "shared/new_contact", locals: { :contact => #contact }.
