I'm running into the same thing. I think I corrected everything as shown above, but still no go.
This is from the migration file:
class CreateSignups < ActiveRecord::Migration
create_table :signups do |t|
And this is from the new signups page:
<%= form_for(@signup) do |f| %>
<%= f.label :email %>
<%= f.text_area :email %>
<%= f.submit "Submit" %>
<% end %>
The error message I get is:
Showing /home/ccuser/workspace/learn-rails_innovation-cloud/innovation-cloud/app/views/signups/new.html.erb where line #41 raised:
undefined method `email' for #
Am I missing something?
