Question

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 home.html.erb and is controlled by the pages controller.

I’m getting the following error:

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”

Here’s my code:

home.html.erb has:

    <%= form_for(@signup) do |f| %>
        <div class="field">
            <%= f.text_field :email %>
        </div>

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

Pages controller has:

class PagesController < ApplicationController

  def home
    @title = "Title of my site"
    @signup = Signup.new
  end

end

Signups controller has:

class SignupController < 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

Signup model has:

class Signup < ActiveRecord::Base

  attr_accessible :email

  email_regex = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i

  validates(:email, :presence => true,
                    :length => {:maximum => 40},
                    :format => {:with => email_regex})

end

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.

Answer 1

It’s telling you that a template is missing.

Typically, by default (if you don’t call render() or redirect_to()) Rails renders the view associated with your action so in your case that would be: create.html.erb.

So you should redirect to something that makes more sense if you create a user successfully.

Like:

if @signup.save
   redirect_to :root
else
 #...
end

By the way I am assuming that you have configured the root path first, like this:

root :to => "something"

You’ll redirect the user where it makes sense to your application.
