How can I make f.error_messages work here, or should I use flashes?
If so, what should override in the sessions_controller?
<h2>Create an account</h2>
<% form_for resource_name, resource, :url => registration_path(resource_name) do |f| %>
<%= f.error_messages %>
<p>
<%= f.label :email %><br />
<%= f.text_field :email, :class => :big %>
</p>
<p>
<%= f.label :password %><br />
<%= f.password_field :password, :class => :big %>
</p>
<p>
<%= f.label :password_confirmation %><br />
<%= f.password_field :password_confirmation, :class => :big %>
</p>
<p><%= f.submit "Create", :class => :submit %></p>
<% end %>
PS. f.error_messages for Creating an account works totally fine.

try putting these in your layout:
<%= content_tag(:div, flash[:error], :id => "flash_error") if flash[:error] %>
<%= content_tag(:div, flash[:notice], :id => "flash_notice") if flash[:notice] %>
<%= content_tag(:div, flash[:alert], :id => "flash_alert") if flash[:alert] %>
Login action in Devise sets flash messages, not model Errors.

Admittedly, a bit hacky, but I'm using this helper (app/helpers/devise_helper.rb) to grab flashes and use those if set then default to resource.errors.
module DeviseHelper
def devise_error_messages!
flash_alerts = []
error_key = 'errors.messages.not_saved'
if !flash.empty?
flash_alerts.push(flash[:error]) if flash[:error]
flash_alerts.push(flash[:alert]) if flash[:alert]
flash_alerts.push(flash[:notice]) if flash[:notice]
error_key = 'devise.failure.invalid'
end
return "" if resource.errors.empty? && flash_alerts.empty?
errors = resource.errors.empty? ? flash_alerts : resource.errors.full_messages
messages = errors.map { |msg| content_tag(:li, msg) }.join
sentence = I18n.t(error_key, :count => errors.count,
:resource => resource.class.model_name.human.downcase)
html = <<-HTML
<div id="error_explanation">
<h2>#{sentence}</h2>
<ul>#{messages}</ul>
</div>
HTML
html.html_safe
end
end
Despite the age of this post I wanted to share a solution to help people such as myself who had trouble when they began using Devise. To keep things DRY I just ended up inserting this code in my application.html.erb file:
<body>
<% flash.each do |key, value| %>
<div class="flash <%= key %>"><%= value %></div>
<% end %>
<%= yield %>
</body>
This shall also do
<% flash.each do |name, msg| %>
<%= content_tag :div, msg, id: "flash_#{name}" %>
<% end %>
