title: Template is missing for signup/create, application/create
body: <p>I'm currently trying to build a simple form that takes an email  address and puts it in the database as part of a landing page. The form is on <code>home.html.erb</code> and is controlled by the <code>pages</code> controller. </p>
  
  <p>I'm getting the following error:</p>
  
  <blockquote>
    <p>Missing template signup/create, application/create with
    {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder,
    :coffee]}. Searched in: *
    "/Users/me/rails_projects/this_project/app/views"</p>
  </blockquote>
  
  <p>Here's my code:</p>
  
  <p><code>home.html.erb</code> has:</p>
  
  <pre><code>    &lt;%= form_for(@signup) do |f| %&gt;
          &lt;div class="field"&gt;
              &lt;%= f.text_field :email %&gt;
          &lt;/div&gt;
  
          &lt;div class="actions"&gt;
              &lt;%= f.submit "Sign up" %&gt;
          &lt;/div&gt;
      &lt;% end %&gt;
  </code></pre>
  
  <p><code>Pages</code> controller has:</p>
  
  <pre><code>class PagesController &lt; ApplicationController
  
    def home
      @title = "Title of my site"
      @signup = Signup.new
    end
  
  end
  </code></pre>
  
  <p><code>Signups</code> controller has:</p>
  
  <pre><code>class SignupController &lt; ApplicationController
  
    def show
      @signup = Signup.new
    end
  
    def new
    end
  
    def create
      @signup = Signup.new(params[:signup])
      if @signup.save
      else
        render 'new'
      end
    end
  
  end
  </code></pre>
  
  <p><code>Signup</code> model has:</p>
  
  <pre><code>class Signup &lt; ActiveRecord::Base
  
    attr_accessible :email
  
    email_regex = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  
    validates(:email, :presence =&gt; true,
                      :length =&gt; {:maximum =&gt; 40},
                      :format =&gt; {:with =&gt; email_regex})
  
  end
  </code></pre>
  
  <p>I'm not sure what's wrong but when I enter a valid email address in the field, this is the error I receive. I've googled around to no avail. Your help would be hugely appreciated.</p>
