• How Does Rails 3's "data-method='delete'" Degrade Gracefully?

  - by viatropos

  Rails 3 does some cool stuff to make Javascript unobtrusive, so they've done things like this: = link_to "Logout", user_session_path, :method => :delete ..converts to <a href="/logout" data-method="delete" rel="nofollow">Logout</a> But it just occurred to me.. When I turn off javascript the method isn't DELETE anymore, it's GET as expected. So are there plans to, or is there some way to, allow these data- attributes to degrade gracefully, so that link still is a DELETE request?

• Why does FastCGI not work well with Ruby on Rails?

So if FastCGI is a viable solution, why is it not reliable with RoR? Does FastCGI work well with most any language / frameworks?

• Rails 3: How to validate that A < B where A and B are both model attributes ?

  - by Misha Moroshko

  I would like to validate that customer_price >= my_price. I tried the following: class Product < ActiveRecord::Base attr_accessor :my_price validates_numericality_of :customer_price, :greater_than_or_equal_to => my_price ... end (customer_price is a column in the Products table in the database, while my_price isn't.) Here is the result: NameError in ProductsController#index undefined local variable or method `my_price' for #<Class:0x313b648> What is the right way to do this in Rails 3 ?

• Rails: Best practice for displaying ActiveRecord validation error in XML Builder?

  - by randombits

  I'm building a RESTful API using Ruby on Rails. My models have a lot of validation happening in them.

  - by Brian Deterling

  I've got a standard Rails app with Nginx and Mongrel running at http://mydomain. I need to run a Wordpress blog at http://mydomain.com/blog. My preference would be to host the blog in Apache running on either the same server or a separate box but I don't want the user to see a different server in the URL. Is that possible and if not, what would you recommend to accomplish the goal?

• What's the best way to generate an API reference document using a Rails routes.rb file?

  - by RNHurt

  I am trying to document the API for my Rails application and I can't help but wonder if there is a better way to generate an XML file based on my routes.rb file. I'm envisioning something similar to the output of rake routes but in a more friendly, XML type format. Corey has some interesting ideas about using reflection/introspection on the routes file here but it's not quite what I need. Please tell me this is a solved problem and I'm not the first one to think of this. :)

• Does rails do a rollback if I use begin...rescue?

  - by codeman73

  I'd like to add a begin...rescue block to one of my controllers create method, in order to log better info and construct the correct error message to return to the client. Does the rescue in any way 'interrupt' the rollback process? I'm assuming rails automatically does a rollback. When does it happen? Has it already happened by the time I get in the rescue clause? I'm using mySQL on Dreamhost and I think they use innoDB.

• How to create picture slideshows in a rails project? Flash or otherwise

  - by Janak

  In a rails project how would I create a picture slideshow? It could be generated as flash or use prototype or something else. I just want a series of images (as a sub-part of a web page, not be the whole page) to fade into each other, and to advance manually if clicked. It would be nice if I could do things like slowly zoom into the images I imagine there must be a plugin or something to handle this?
