• Rspec stubing view for anonymous controller

  - by Colin G

  I'm trying to test a method on the application controller that will be used as a before filter. To do this I have setup an anonymous controller in my test with the before filter applied to ensure that it functions correctly. The test currently looks like this: describe ApplicationController do controller do before_filter :authenticated def index end end describe "user authenticated" do let(:session_id){"session_id"} let(:user){OpenStruct.new(:email => "[email protected]", :name => "Colin Gemmell")} before do request.cookies[:session_id] = session_id UserSession.stub!(:find).with(session_id).and_return(user) get :index end it { should assign_to(:user){user} } end end And the application controller is like this: class ApplicationController < ActionController::Base protect_from_forgery def authenticated @user = nil end end My problem is when ever I run the test I'm getting the following error 1) ApplicationController user authenticated Failure/Error: get :index ActionView::MissingTemplate: Missing template stub_resources/index with {:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml, :haml], :formats=>[:html], :locale=>[:en, :en]} in view paths "#<RSpec::Rails::ViewRendering::PathSetDelegatorResolver:0x984f310>" According to the docs the view is not rendered when running controller tests however this points to no stub existing for this action (which is understandable as the view doesn't exist) Anyone have a clue how to solve this problem or stub the view out. Cheers Colin G

• Retactoring advanced has_many example

  - by atmorell

  Hello, My user model has three relations for the same message model, and is using raw SQL :/ Is there a better more rails way to achieve the same result? Could the foreign key be changed dynamically? e.g User.messages.sent (foreign key = author_id) and User.messages.received (foreign key = recipient ) I have been trying to move some of the logic into scopes in the message model, but the user.id is not available from the message model... Any thoughts? Table layout: create_table "messages", :force => true do |t| t.string "subject" t.text "body" t.datetime "created_at" t.datetime "updated_at" t.integer "author_id" t.integer "recipient_id" t.boolean "author_deleted", :default => false t.boolean "recipient_deleted", :default => false end This is my relations for my user model: has_many :messages_received, :foreign_key => "recipient_id", :class_name => "Message", :conditions => ['recipient_deleted = ?', false] has_many :messages_sent, :foreign_key => "author_id", :class_name => "Message", :conditions => ['author_deleted = ?', false] has_many :messages_deleted, :class_name => "Message", :finder_sql => 'SELECT * FROM Messages WHERE author_id = #{self.id} AND author_deleted = true OR recipient_id = #{self.id} AND recipient_deleted = true' Best regards.

• Omniauth/Devise/Facebook: Auth route is not recognized

  - by M. Cypher

  I've been working on this problem for 7 hours now, and I still have no idea. Maybe one of you can help me. I'm simply trying to integrate the OAuth feature of Devise 1.2rc, which uses Omniauth, into my Rails application. I've been using this tutorial by Devise: https://github.com/plataformatec/devise/wiki/OmniAuth%3A-Overview I have done everything they tell you to... Yes, I have added the following line to my devise.rb: config.omniauth :facebook, "APP ID", "APP SECRET" I have added :omniauthable to my user model, as well as the class function as described in the tutorial I have implemented the omniauth_callbacks controller, as well as the callback function, and I have specified the omniauth_callbacks controller in my routes.rb When I run "rake middleware" it does list the Omniauth middleware: use OmniAuth::Strategies::Facebook I have installed Devise directly from the Git repo, master branch, so it's up-to-date I have installed Omniauth 1.2.0.beta5, which is the latest version. In my Gemfile it says: gem 'oa-oauth', '0.2.0.beta5', :require = 'omniauth/oauth' I have restarted the server, obviously However, when I try to request this URL: http://localhost:3000/auth/facebook it simply says ActionController::RoutingError (No route matches "/auth/facebook"): /user/auth/facebook doesn't work either. Since I unfortunately don't have the time to take apart the entire Omniauth and Devise gems and understand every line of code in them, maybe one of you could tell me what the problem might be.

• UUIDs in Rails3

  - by Rob Wilkerson

  I'm trying to setup my first Rails3 project and, early on, I'm running into problems with either uuidtools, my UUIDHelper or perhaps callbacks. I'm obviously trying to use UUIDs and (I think) I've set things up as described in Ariejan de Vroom's article. I've tried using the UUID as a primary key and also as simply a supplemental field, but it seems like the UUIDHelper is never being called. I've read many mentions of callbacks and/or helpers changing in Rails3, but I can't find any specifics that would tell me how to adjust. Here's my setup as it stands at this moment (there have been a few iterations): # migration class CreateImages < ActiveRecord::Migration def self.up create_table :images do |t| t.string :uuid, :limit => 36 t.string :title t.text :description t.timestamps end end ... end # lib/uuid_helper.rb require 'rubygems' require 'uuidtools' module UUIDHelper def before_create() self.uuid = UUID.timestamp_create.to_s end end # models/image.rb class Image < ActiveRecord::Base include UUIDHelper ... end Any insight would be much appreciated. Thanks.

• What is the form_for syntax for nested resources?

  - by Kris

  I am trying to create a form for a nested resource. Here is my route: map.resources :websites do |website| website.resources :domains end Here are my attempts and the errors: <% form_for(@domain, :url => website_domains_path(@website)) do | form | %> <%= form.text_field :name %> # ArgumentError: wrong number of arguments (1 for 0) # form_helper.rb:290:in 'respond_to?' # form_helper.rb:290:in 'apply_form_for_options!' # form_helper.rb:277:in 'form_for' <% form_for([@website, @domain]) do | form | %> <%= form.text_field :name %> # ArgumentError: wrong number of arguments (1 for 0) # form_helper.rb:290:in 'respond_to?' # form_helper.rb:290:in 'apply_form_for_options!' # form_helper.rb:277:in 'form_for' <% form_for(:domain, @domain, :url => website_domains_path(@website)) do | form | %> <%= form.text_field :name %> # ArgumentError: wrong number of arguments (1 for 0) # wrapper.rb:14:in 'respond_to?' # wrapper.rb:14:in 'wrap' # active_record_helper.rb:174:in 'error_messages_for' <% form_for(:domain, [@website, @domain]) do | form | %> <%= form.text_field :name %> # UndefinedMethodError 'name' for #<Array:0x40fa498> I have confirmed both @website and @domain contain instances of the correct class.

• 'Stack level too deep' error in engine-like plugin with globalize

  - by nutsmuggler

  Hello folks. I have built an engine-like plugin thanks to the new features of Rails 2.3. It's a 'Product' module for a CMS, extrapolated from a previously existing (and working) model/controller. The plugin relies on easy_fckeditor and on globalize (description and title field are localised), and I suspect that globalized could be the culprit here... Everything works fine, except for the update action. I get the following error message: (posting just the first lines, all the message is about attribute_methods) stack level too deep /Library/Ruby/Gems/1.8/gems/activerecord-2.3.2/lib/active_record/attribute_methods.rb:64:in `generated_methods?' /Library/Ruby/Gems/1.8/gems/activerecord-2.3.2/lib/active_record/attribute_methods.rb:241:in `method_missing' /Library/Ruby/Gems/1.8/gems/activerecord-2.3.2/lib/active_record/attribute_methods.rb:249:in `method_missing' For referenze, the full error stack is here: http://pastie.org/596546 I've tried to debug eliminating all the input fields, one by one, but I keep getting the error. fckeditor doesn't seem the culprit (error even without fckeditor) This is the action: def update params[:product][:term_ids] ||= [] @product = Product.find(params[:id]) respond_to do |format| if @product.update_attributes(params[:product]) flash[:notice] = t(:Product_was_successfully_updated) format.html { redirect_to products_path } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @product.errors, :status => :unprocessable_entity } end end end As you see it's quite straightforward. Of course I am not hoping someone to solve this question straightaway, I'd just like to have a head up, a suggestion about where to look to solve this issue. Thanks in advance, Davide

• Seed has_many relation using mass assignment

  - by rnd

  Here are my two models: class Article < ActiveRecord::Base attr_accessible :content has_many :comments end class Comment < ActiveRecord::Base attr_accessible :content belongs_to :article end And I'm trying to seed the database in seed.rb using this code: Article.create( [{ content: "Hi! This is my first article!", comments: [{content: "It sucks"}, {content: "Best article ever!"}] }], without_protection: true) However rake db:seed gives me the following error message: rake aborted! Comment(#28467560) expected, got Hash(#13868840) Tasks: TOP => db:seed (See full trace by running task with --trace) It is possible to seed the database like this? If yes a follow-up question: I've searched some and it seems that to do this kind of (nested?) mass assignment I need to add 'accepts_nested_attributes_for' for the attributes I want to assign. (Possibly something like 'accepts_nested_attributes_for :article' for the Comment model) Is there a way to allow this similar to the 'without_protection: true'? Because I only want to accept this kind of mass assignment when seeding the database.

  I have two models: class Solution < ActiveRecord::Base belongs_to :owner, :class_name => "User", :foreign_key => :user_id end class User < ActiveRecord::Base has_many :solutions end with the following routing: map.resources :users, :has_many => :solutions and here is the SolutionsController: class SolutionsController < ApplicationController before_filter :load_user def index @solutions = @user.solutions end private def load_user @user = User.find(params[:user_id]) unless params[:user_id].nil? end end Can anybody help me with writing a test for the index action?

• hosting a high traffic facebook app (game)

  - by z3cko

  we are currently developing a high traffic facebook application. all the traffic will be within one month, where there are 500.000 to 1.000.000 expected users. after that month, the game is over and we have a winner - so the app will be archived. we are currently planning to develop the application with ruby on rails and searching for hosting options that can deal with the traffic. the problem is not so much the users, but the peak values: we will have around 500.000 requests coming daily within a short timeframe (lets say within 3 minutes in the worst case) we are expecting 500.000 to 1.000.000 users of the application, with peaks at 1:00pm (timezone GMT+1), where most (up to 80% of the users) will send most of the requests. the requests are from 11th of june to 11.july - after that, the app/game is closed/over. we are currently developing an aggressive caching mechanism - currently we are thinking about 2 or 3 small apps/webservices, that will handle the load. the load is distributed as follows: a) main application, cached data (11 screens, 200k each) b) voting: every day until 1:00pm (timezone GMT+1) - every user votes with about 10k data sent, high concurrent peak values! questions: is there any specific application setup that is recommendable? are there any hosting partners that can be recommended? thanks!

• Namespaced controller redirect urls

  - by bajki

  Hello, i have probably a simple question. I have created a namespace panel with categories controller. After creating or editing a category, rails redirects me to website.com/categories/:id instead of website.com/panel/categories/:id. I've noticed that in the _form view, the @panel_categories argument of form_for() function points to /categories nor /panel/categories and that's causing this behaviour. Offcourse i can add a :url => '/panel/categories' param but i feel that it's not the best solution... Can you provide me any better solution? Thanks in advance Files: routes.rb: Photowall::Application.routes.draw do resources :photos resources :categories resources :fields resources :users, :user_sessions match 'login' => 'user_sessions#new', :as => :login match 'logout' => 'user_sessions#destroy', :as => :logout namespace :panel do root :to => "photos#index" resources :users, :photos, :categories, :fields end namespace :admin do root :to => "users#index" resources :users, :photos, :categories, :fields end end categories_controller.rb: http://pastebin.com/rWJykCCF model is the default one form: http://pastebin.com/HGmkZZHM

• How do I use Haml in a view in my new plugin?

  - by Eric

  I'm creating a new plugin for a jruby on rails application that will eventually be turned into a gem. Inside my plugin I have controllers, helpers and views. For my views I'd like to use Haml. The problem is that I can't seem to get it to recognize that they are haml templates. Is it even possible to do this? Is there a way for a plugin to have Haml as a dependency for its view? And by that I mean, I intend for the plugin that I'm creating to have a view created by the plugin, that can be used by the application developer. for example: vendor/ plugins/ my_plugin/ lib/ app/ views/ my_plugin_demo/ index.haml.html controllers/ my_plugin_demo_controller.rb helpers/ In my plugin's init.rb, I tried: require 'my_plugin' require 'haml' #doesn't seem to make a difference :( but that didn't seem to make any difference. Has anybody had any experience with this? I can't seem to find any documentation on how to make this work. Are plugin views restricted to .erb templates?

• How to handle ids and polymorphic associations in views if compound keys are not supported?

  - by duncan

  I have a Movie plan table: movie_plans (id, description) Each plan has items, which describe a sequence of movies and the duration in minutes: movie_plan_items (id, movie_plan_id, movie_id, start_minutes, end_minutes) A specific instance of that plan happens in: movie_schedules (id, movie_plan_id, start_at) However the schedule items can be calculated from the movie_plan_items and the schedule start time by adding the minutes create view movie_schedule_items as select CONCAT(p.id, '-', s.id) as id, s.id as movie_schedule_id, p.id as movie_plan_item_id, p.movie_id, p.movie_plan_id, (s.start_at + INTERVAL p.start_minutes MINUTE) as start_at, (s.start_at + INTERVAL p.end_minutes MINUTE) as end_at from movie_plan_items p, movie_schedules s where s.movie_plan_id=p.movie_plan_id; I have a model over this view (readonly), it works ok, except that the id is right now a string. I now want to add a polymorphic property (like comments) to various of the previous tables. Therefore for movie_schedule_items I need a unique and persistent numeric id. I have the following dilemma: I could avoid the id and have movie_schedule_items just use the movie_plan_id and movie_schedule_id as a compound key, as it should. But Rails sucks in this regard. I could create an id using String#hash or a md5, thus making it slower or collision prone (and IIRC String#hash is no longer persistent across processes in Ruby 1.9) Any ideas on how to handle this situation?

• Why is my rspec test failing?

  - by Justin Meltzer

  Here's the test: describe "admin attribute" do before(:each) do @user = User.create!(@attr) end it "should respond to admin" do @user.should respond_to(:admin) end it "should not be an admin by default" do @user.should_not be_admin end it "should be convertible to an admin" do @user.toggle!(:admin) @user.should be_admin end end Here's the error: 1) User password encryption admin attribute should respond to admin Failure/Error: @user = User.create!(@attr) ActiveRecord::RecordInvalid: Validation failed: Email has already been taken # ./spec/models/user_spec.rb:128 I'm thinking the error might be somewhere in my data populator code: require 'faker' namespace :db do desc "Fill database with sample data" task :populate => :environment do Rake::Task['db:reset'].invoke admin = User.create!(:name => "Example User", :email => "[email protected]", :password => "foobar", :password_confirmation => "foobar") admin.toggle!(:admin) 99.times do |n| name = Faker::Name.name email = "example-#{n+1}@railstutorial.org" password = "password" User.create!(:name => name, :email => email, :password => password, :password_confirmation => password) end end end Please let me know if I should reproduce any more of my code. UPDATE: Here's where @attr is defined, at the top of the user_spec.rb file: require 'spec_helper' describe User do before(:each) do @attr = { :name => "Example User", :email => "[email protected]", :password => "foobar", :password_confirmation => "foobar" } end

• How to insert rows in a many-to-many relationship

  - by GSound

  Hello, I am having an issue trying to save into an intermediate table. I am new on Rails and I have spent a couple of hours on this but can't make it work, maybe I am doing wrong the whole thing. Any help will be appreciated. =) The app is a simple book store, where a logged-in user picks books and then create an order. This error is displayed: NameError in OrderController#create uninitialized constant Order::Orderlist These are my models: class Book < ActiveRecord::Base has_many :orderlists has_many :orders, :through => :orderlists end class Order < ActiveRecord::Base belongs_to :user has_many :orderlists has_many :books, :through => :orderlists end class OrderList < ActiveRecord::Base belongs_to :book belongs_to :order end This is my Order controller: class OrderController < ApplicationController def add if session[:user] book = Book.find(:first, :conditions => ["id = #{params[:id]}"]) if book session[:list].push(book) end redirect_to :controller => "book" else redirect_to :controller => "user" end end def create if session[:user] @order = Order.new if @order.save session[:list].each do |b| @order.orderlists.create(:book => b) # <-- here is my prob I cant make it work end end end redirect_to :controller => "book" end end Thnx in advance!

• Creating nested fields for column on assignment table?

  - by H O

  I have three models, that represent a many to many relationship - Product, Sale and Product_sale. I have a nested form that allows me to create new products from the sale form - so far, so good. I have, however, added some additional fields to the assignment table - price, for example. How can I set the price on the assignment table from the product form, when it is nested in the sale form? I currently have the code below: <%= sale.fields_for :products do |products_builder| %> <%= render :partial => "products/form", :locals => {:f => products_builder, :form_actions_visible => false} %> <% end -%> I could nest a Product_sale form within the product form, but this would create a new product_sale, which is not what I am looking for. I will most likely need to nest the price field within the product form, to ensure that it updates the correct assignment record (since there could be multiple products on one sale form). How can I use a fields_for loop on the product form to update the existing assignment record that is built when I do @sale.products.build? The assignment record will not yet be saved, so I can not access it using a where clause and edit it that way. Thanks!

• Please help rails problem with stringify_keys error

  - by richard moss

  I have been trying to solve this for ages and can't figure it out. I have a form like so (taking out a lot of other fields) <% form_for @machine_enquiry, machine_enquiry_path(@machine_enquiry) do|me_form| %> <% me_form.fields_for :messages_attributes do |f| %> <%= f.text_field :title -%> <% end %> <%= me_form.submit 'Send message' %> <% end %> And an update action like @machine_enquiry = MachineEnquiry.find(params[:id]) @machine_enquiry.update_attributes(params[:machine_enquiry] And a machine_enquiry class like so: class MachineEnquiry < ActiveRecord::Base has_many :messages, :as => :messagable, :dependent => :destroy accepts_nested_attributes_for :messages end I am getting an error like so: NoMethodError in Machine enquiriesController#update undefined method `stringify_keys' for "2":String RAILS_ROOT:

• Filter chain halted as [:login_required] rendered_or_redirected

  - by Magicked

  Hopefully I can explain this well enough, but please let me know if more information is needed! I'm building a form where a user can create an "incident". This incident has the following relationships: belongs_to: customer (customer has_many incidents) belongs_to: user (user has_many incidents) has_one: incident_status (incident_status belongs to incident) The form allows the user to assign the incident to a user (select form) and then select an incident status. The incident is nested in customer. However, I'm getting the following in the server logs: Processing IncidentsController#create (for 127.0.0.1 at 2010-04-26 10:41:33) [POST] Parameters: {"commit"=>"Create", "action"=>"create", "authenticity_token"=>"YhW++vd/dnLoNV/DSl1DULcaWq/RwP7jvLOVx9jQblA=", "customer_id"=>"4", "controller"=>"incidents", "incident"=>{"title"=>"Some Bad Incident", "incident_status_id"=>"1", "user_id"=>"2", "other_name"=>"SS01-042310-001"}} User Load (0.3ms) SELECT * FROM "users" WHERE ("users"."id" = 2) LIMIT 1 Redirected to http://localhost:3000/session/new Filter chain halted as [:login_required] rendered_or_redirected. Completed in 55ms (DB: 0) | 302 Found [http://localhost/customers/4/incidents] It looks to me like it's trying to gather information about the user, even though it already has the id (which is all it needs to create the incident), and the user may not have permission to do a select statement like that? I'm rather confused. Here is the relevant (I think) information in the Incident controller. before_filter :login_required, :get_customer def new @incident = @customer.incidents.build @users = @customer.users @statuses = IncidentStatus.find(:all) respond_to do |format| format.html # new.html.erb format.xml { render :xml => @incident } end end def create @incident = @customer.incidents.build(params[:incident]) respond_to do |format| if @incident.save flash[:notice] = 'Incident was successfully created.' format.html { redirect_to(@incident) } format.xml { render :xml => @incident, :status => :created, :location => @incident } else format.html { render :action => "new" } format.xml { render :xml => @incident.errors, :status => :unprocessable_entity } end end end Just as an FYI, I am using the restful_authentication plugin. So in summary, when I submit the incident creation form, it does not save the incident because it halts. I'm still very new to rails, so my skill at diagnosing problems like this is still very bad. I'm going in circles. :) Thanks in advance for any help. Please let me know if more information is needed and I'll edit it in!

• How to troubleshoot a Highcharts script that's not rendering data when date is added and hanging the JS engine with large datasets?

  - by ylluminate

  I have a Highchart JS graph that I'm building in Rails (although I don't think Ruby has real bearing on this problem unless it's the Date output format) to which I'm adding the timestamp of each datapoint. Presently the array of floats is rendering fine without timestamps, however when I add the timestamp to the series it fails to rend. What's worse is that when the series has hundreds of entries all sorts of problems arise, not the least of which is the browser entirely hanging and requiring a force quit / kill. I'm using the following to build the array of arrays data series: series1 = readings.map{|row| [(row.date.to_i * 1000), (row.data1.to_f if BigDecimal(row.data1) != BigDecimal("-1000.0"))] } This yields a result like this: series: [{"name":"Data 1","data":[[1326262980000,1.79e-09],[1326262920000,1.29e-09],[1326262860000,1.22e-09],[1326262800000,1.42e-09],[1326262740000,1.29e-09],[1326262680000,1.34e-09],[1326262620000,1.31e-09],[1326262560000,1.51e-09],[1326262500000,1.24e-09],[1326262440000,1.7e-09],[1326262380000,1.24e-09],[1326262320000,1.29e-09],[1326262260000,1.53e-09],[1326262200000,1.23e-09],[1326262140000,1.21e-09]],"color":"blue"}] Yet nothing appears on the graph as noted. Notwithstanding, when I compare the data series in one of their very similar examples here: http://www.highcharts.com/demo/spline-irregular-time It appears that really the data series are formatted identically (except in mine I use the timestamp vs date method). This leads me to think I've got a problem with the timestamp output, but I'm just not able to figure out where / how as I'm converting the date output to an integer multipled by 1000 to convert it to milliseconds as per explained in a similar Railscasts tutorial. I would very much appreciate it if someone could point me in the right direction here as to what I may be doing wrong. What could cause no data to appear on the graph in smaller sized sets (<100 points) and when into the hundreds causes an apparent hang in the javascript engine in this case? Perhaps ultimately the key lies here as this is the entire js that's being generated and not rendering: jQuery(function() { // 1. Define JSON options var options = { chart: {"defaultSeriesType":"spline","renderTo":"chart_name"}, title: {"text":"Title"}, legend: {"layout":"vertical","style":{}}, xAxis: {"title":{"text":"UTC Time"},"type":"datetime"}, yAxis: [{"title":{"text":"Left Title","margin":10}},{"title":{"text":"Right Groups Title"},"opposite":true}], tooltip: {"enabled":true}, credits: {"enabled":false}, plotOptions: {"areaspline":{}}, series: [{"name":"Data 1","data":[[1326262980000,1.79e-08],[1326262920000,1.69e-08],[1326262860000,1.62e-08],[1326262800000,1.42e-08],[1326262740000,1.29e-08],[1326262680000,1.34e-08],[1326262620000,1.31e-08],[1326262560000,1.51e-08],[1326262500000,1.64e-08],[1326262440000,1.7e-08],[1326262380000,1.64e-08],[1326262320000,1.69e-08],[1326262260000,1.53e-08],[1326262200000,1.23e-08],[1326262140000,1.21e-08]],"color":"blue"},{"name":"Data 2","data":[[1326262980000,9.79e-09],[1326262920000,9.78e-09],[1326262860000,9.8e-09],[1326262800000,9.82e-09],[1326262740000,9.88e-09],[1326262680000,9.89e-09],[1326262620000,1.3e-06],[1326262560000,1.32e-06],[1326262500000,1.33e-06],[1326262440000,1.33e-06],[1326262380000,1.34e-06],[1326262320000,1.33e-06],[1326262260000,1.32e-06],[1326262200000,1.32e-06],[1326262140000,1.32e-06]],"color":"red"}], subtitle: {} }; // 2.

• Do Django Models inherit managers? (Mine seem not to)

  - by Zach

  I have 2 models: class A(Model): #Some Fields objects = ClassAManager() class B(A): #Some B-specific fields I would expect B.objects to give me access to an instance of ClassAManager, but this is not the case.... >>> A.objects <app.managers.ClassAManager object at 0x103f8f290> >>> B.objects <django.db.models.manager.Manager object at 0x103f94790> Why doesn't B inherit the objects attribute from A?

• Custom Rails 3 Date Format

  - by Jack

  Hi, I am trying to format a date as follows using Rails 3; 3rd June 2003. This is not a standard way of showing the date, so I have looked into a custom way of doing it. Rails 3.0 documentation here suggests that I add a file at config/initializers/time_formats.rb containing the following code: Time::DATE_FORMATS[:custom_date] = lambda { |time| time.strftime("#{time.day.ordinalize} %B %Y") } And then call it using something like: <%= document.publish_date.to_formatted_s(:custom_date) %> However this isn't working and the date is being formatted as YYYY-MM-YY. Does anyone have any suggestions? Cheers
