由于表单，Rails 3'新'动作作为索引页面

Question

I have a small app where the index page is a form that instructs the user for their email, I have changed my route so that the root_path is the 'new' action which renders my form:

Oa::Application.routes.draw do
  resources :signups
  match "/confirm", :to => "pages#confirm"
  root :to => 'signups#new'
end

This is working fine, when I submit the form it is working fine. When I submit on the root page and I cause a validation error the address bar has the url localhost:3000/signups and shows me my validation errors, which is also good but if I were to manually visit http://localhost:3000/signups it gives me an error "The action 'index' could not be found for SignupsController". Would it be ok if I created the 'index' action and redirect_to root_path so that I don't receive the "The action 'index' could not be found for SignupsController" if I were to access http://localhost:3000/signups directly? Is this the proper way to do this?

class SignupsController < ApplicationController
  def index
    redirect_to root_path
  end

  def new
    @signup = Signup.new
  end

  def create
@signup = Signup.new(params[:signup])
if @signup.save
      UserMailer.registration_confirmation(@signup).deliver
  flash[:notice] = "Signup created successfully."
  redirect_to confirm_path
else
  render :action => "new"
    end
  end
end

Thanks!

Answer 1

Do something like this:

post '/' => 'signups#create'
root to: 'signups#new'

Do not use resources :signups

Answer 2

The reason that http://localhost:3000/signups gives me an error "The action 'index' could not be found for SignupsController" is because:

The first 'matched' routes is used.
So all of this:

match "/confirm", :to => "pages#confirm"
root :to => 'signups#new'

is ignored by the /signups URL because IT gets dealt with by

resources :signups

which creates all the routes - index, show, create, new, edit, update, destroy

and when 'signups' is used it implies the signups index action.

Try removing it and/or reading up on RESTful routes in rails and apply that.
