Question

I’m trying to show my errors (both flash and devise) in one of my layout files (_header.html.erb):

<div id="alerts">
<% flash.each do |name, msg| %>
  <%= content_tag :div, msg, :id => "flash_#{name}" if msg.is_a?(String) %>
<% end %>
  <%= devise_error_messages! %>
</div>

but I’m getting an error: undefined local variable or method `resource’, because the error message is no longer in the devise form. I tried the method suggested here: http://pupeno.com/2010/08/29/show-a-devise-log-in-form-in-another-page/ by pasting that code into the application_controller.rb file. No luck. Ideas?

oh. I forgot to mention… The pages work without error, but my tests are failing… Here’s a failing test:

it 'succeeds with a valid email and password' do
  user = Factory.create(:user)

  visit sign_in_path
  fill_in 'user_email', :with => user.email
  fill_in 'user_password', :with => user.password
  click_button 'Sign in'
  page.should have_content("hi #{user.username}")
end

This is Rails3, fyi.

turns out the code needed to be in the application_helper instead of the controller, but the code at pupeno.com works!
