I have a page that renders a series of about 20 checkboxes on the left hand side with content on the right. These checkboxes are created from a DB and that part is all working well. What I want to do is have a user click on a checkbox [genres] and have the content on the right be filtered based on the checkbox ticked. If a user clicks on more than one checkbox than only those stories

Hello, I'm thinking of ordering an OpenVox A400P01 (A400P + 1 PORT FXO Bundle) for use in a old IBM 8364 thin client: http://www.openvox.com.cn/products_detail.php?genre_id=9&id=28 http://silicon-verl.de/home/flo/software/netstation-8364/ Has someone already used this hardware with Asterisk, especially on a small piece of hardware like this, and could offer some feedback? Thank you.

Hello Has someone used the OpenVox A400P01 (ie. a supposedly Digium-compatible A400P board with a single FXO module www.openvox.com.cn/products_detail.php?genre_id=9&id=28) successfully? I've put it in an older PC with a Gigabyte GA-7ZX motherboard, then a more recent PC with an Asrock K8NF4G-SATA2: dmesg returns nothing :-/ Is there something specific that needs to be done in either

Is there any product that's a single port mini-PCI FXS card? I'm aware of the Openvox A400M <http://www.openvox.com.cn/products.php?genre_id=39>, but I really only wanted one port. How about a single or dual port PCI or PCI express FXS card? Basically I wanted to build a small linux router with one or two phone ports. Alternatively, is there already a router or single board

Hello Now that I received an OpenVox PCI card (www.openvox.com.cn/products_detail.php?genre_id=9&id=28), I'm ready to try and set up a voice server with Asterisk. We need the following features: 1. When customers call in, they should hear a voice menu asking them which software they're calling about 2. Next, they should be able to leave a voice message to explain what their problem

Hello everyone! Ive been on rails for the last month or so and really enjoyed this framework. However its very hard to find documentation on how to do things right! For example every beginner after a while realizes that having similar CRUD actions in every controller and views for them is not DRY at all! Few days ago I found http://dereksivers.com/rails-shared-controller.html I quite like his

I tend to write a fresh description block for every change in the parameters for that specific action, because I hate conditionals in the example describtion, e.g.: describe SomeController, "handling GET /path/with/param/3" do it "should do this" it "should not do this if" it "should still do that in both cases" end Seperate description blocks keep

I''ve got 8 scaffolds, each one can be considered an ''item'', such as a blog, photo, etc. Using login_engine and user_engine, I list all blogs belonging to a user by saying: @user=session[:user] @blogs=@user.blogs.find(:all) but then let''s say I want to create an option where I want to slice it differently: @user=session[:user] if @someOption ==1

Why select_date and select_date? I dont understand why having both (backward compat?). I also look that their source are different, one use the InstanceTag and others calls 3 select_(year, month, day) functions.

Given the case of validating the presence of an attribute and then performing other tests on said attribute, how do you go about not having to check for nil in the other tests? Example: validates_presence_of :start_date, :end_date validate :validate_start_date_before_end_date def validate_start_date_before_end_date # without this check an exception will be thrown on access to the

Sorry, search is down on the forum, so I don''t know if this has been posted elsewhere. I have some config variables that I want to have set in all environments, and overridden in production. What I want to do is put this in my config/environment.rb SOME_CONFIG = 555 And then override it in config/environments/production.rb as: SOME_CONFIG = 333 Problem is, using constants I

I have a heap of fill-out-form/send-website-operator-mail/send-user-confirmation types of forms. It''s daunting when you think about how many files it takes to do this. I''m not coming up with an obvious "Rails" way to pull it off, so I thought it''d be good to know if anyone else has worked through this (7 per form!). models/ my_form_data.rb

In an attempt to provide a gracefully degradable link_to_remote, I repeat myself every time: <%= link_to_remote(''Signup'', {:url => {:controller => ''user'', :action => ''signup''}}, {:href => url_for(:controller => ''user'', :action => ''signup'')}) %> Looked around the RDoc &
