Is there a way to tell if a user on my website has left (i.e. connection dropped, navigated away etc.) in real time? I am building a RoR website and want to initiate an event as soon as a user leaves my site for whatever reason (e.g. connection, navigating away from domain etc.) Thanks in advance for any help. ...
When attempting to write/read cookies that have brackets in the name, it seems like Rails can't handle this. For example: cookies["example[]"] = "value" This causes the cookie name to be "example%5B%5D" instead of "example[]". Similarly, if I already have a cookie set with the name "example[]", then it seems like Rails is unable to ...
I checked IRC for redmine and was unable to get help. I was conflicted on weather to stick this on Superuser, ServerFault or here, but as my problem is technically programming oriented I decided to look for help here. We have a Mercurial repository system with a layout based on projects that addresses our needs. I wrote some shell scrip...

I have a database that is shared among possible different Ruby on Rails processes. To keep consistency, I would like the record I operate on is up-to-date. I am hoping to solve this problem: process A reads a record, process B reads the same record, process A update the record, (now the instance of record in process B is stale). Since t...

I have a model called Aircraft, inflected as uncountable, and it's driving me nuts. What is the correct way to handle this in Rails 3 "beta 4"? resources :aircraft do member do get :flights end end # Of course these work for some actions and not others. match 'aircraft', :to => 'aircraft#index', :as => :aircraft match 'aircraft...

Posts belong to Users. Users have and belong to many roles (i.e., the tables we're dealing with here are posts, users, roles, and roles_users) How can I select all posts written by a user who has the "Editor" role? I.e., I want the database-driven version of Post.all.select{|p| p.user.roles.map(&:name).include?("Editor")}} ...

If you are not familiar, in your browser, you can click a button on the toolbar and it captures a pretty accurate copy of the webpage layout. For an example, go to http://www.evernote.com/pub/jssmith072/shared and click on the single note ...
Suppose you want to show a message to a user who has logged in for the first time like, "Thanks for signing up". Of course this is easy to achieve, but it seems a waste to check if it is their first visit (by any mechanism) every time thereafter. Is it possible to do it in any way that doesn't involve checking every time? I suppose th...

What's your preferred method of sanitizing embed code entered in a form? In other words, is there an easy way of ONLY allowing users to embed video from YouTube and Vimeo for example? Do you use the Sanitize helper? If there is a proven solution to this I'd prefer to use it rather than reinventing the wheel. Thank you for reading my ques...
