Question

Update:
Checking the console, a lot of the users are actually going into the database, even when this error message appears!

Even weirder, you will notice that I have a redirect to root_path on a successful save to the database. it never goes there. This is the log. If it saves, it sometimes goes to the show action but there’s actually a moment when the browser appears to get stuck, everything blanks it and I have to click in the address field to push it through to show.index.html.

Original Question:

I’m creating a form for users to sign up to win an ipad. It’s got two fields, email and name.
When I submit the form, I keep getting the same error message no matter what email i enter

1 error prohibited this from being saved:

There were problems with the following fields:

    Email has already been taken

Strangely, when I debug params, it shows whatever new email address I enter.

utf8: "\xE2\x9C\x93"
authenticity_token: UgkHFLBfKYM2tZ11u6ItWvPS5XeTIMhFuJDwvhgqe30=
ipad: !map:ActiveSupport::HashWithIndifferentAccess 
  name: Amy
  email: [e-mail]
commit: Sign up
action: create
controller: ipads

Anyone have any idea? I’m a bit of a noob…

I’m just adding this code to an Enki blog I’m making on Rails…

I have this validation on my ipad.rb model (note, I had a column for a Twitter address in the migration that I’m just ignoring in the form)

attr_accessible :name, :email, :twitter

validates :name, :presence => true,
         :length   => { :maximum => 50 }
validates :email, :presence => true,
                  :uniqueness => true

This is my ipads_controller.rb

class IpadsController < ApplicationController

  def new
    @ipad = Ipad.new
    @title = "iPad Contest"
  end

  def create
    @ipad = Ipad.new(params[:ipad])
    if @ipad.save
      redirect_to 'root_path'
    else
      @title = "Poo"
      render 'new'
    end
  end


end

This is my new.html.erb

<h1>Win an iPad</h1>
<%= @title %>

<h1>Sign up for iPad</h1>

<%= form_for(@ipad) do |f| %>
<%= render 'shared/errror_messages' %>
  <div class="field">
    <%= f.label :name %><br />
    <%= f.text_field :name %>
  </div>
  <div class="field">
    <%= f.label :email %><br />
    <%= f.text_field :email %>
  </div>

  <div class="actions">
    <%= f.submit "Sign up" %>
  </div>
<% end %>


<%= debug params %> 

Answer 1

Using redirect_to root_path instead of redirect_to ‘root_path’ fixed it. Noob error.
