Hello,

Because I want to change something on login I copied the standard
sessions
controller to /app/controllers.
Code :

class Devise::SessionsController < DeviseController
  prepend_before_filter :require_no_authentication, :only => [ :new,
:create ]
  prepend_before_filter :allow_params_authentication!, :only => :create
  prepend_before_filter { request.env["devise.skip_timeout"] = true }

  # GET /resource/sign_in
  def new
    self.resource = build_resource(nil, :unsafe => true)
    clean_up_passwords(resource)
    respond_with(resource, serialize_options(resource))
  end

  # POST /resource/sign_in
  def create
    self.resource = warden.authenticate!(auth_options)
    set_flash_message(:notice, :signed_in) if is_navigational_format?
    sign_in(resource_name, resource)
    respond_with resource, :location => after_sign_in_path_for(resource)
  end

  # DELETE /resource/sign_out
  def destroy
    redirect_path = after_sign_out_path_for(resource_name)
    signed_out = (Devise.sign_out_all_scopes ? sign_out :
sign_out(resource_name))
    set_flash_message :notice, :signed_out if signed_out &&
is_navigational_format?

    # We actually need to hardcode this as Rails default responder
doesn't
    # support returning empty response on GET request
    respond_to do |format|
      format.any(*navigational_formats) { redirect_to redirect_path }
      format.all do
        head :no_content
      end
    end
  end

  protected

  def serialize_options(resource)
    methods = resource_class.authentication_keys.dup
    methods = methods.keys if methods.is_a?(Hash)
    methods << :password if resource.respond_to?(:password)
    { :methods => methods, :only => [:password] }
  end

  def auth_options
    { :scope => resource_name, :recall => "#{controller_path}#new" }
  end
end

Also I changed this in routes.rb :

devise_for :users, :controllers => { :sessions => "sessions" }

but when  I want to log in I see this error message :

expected
/home/roelof/tamara_devise/app/controllers/sessions_controller.rb to

with this trace :

Maybe it's gritching about the difference between
Devise::SessionsController (which you've got there) and just plain
SessionsController (which it says it's expecting that file to define).
 Try removing the Devise:: part.
