ruby-on-rails-3.1

I still don't quite get it, where to put images in rails 3.1, in these situation: Images are processed (f.e. by paperclip or by dragonfly ) and stored in folder (not with external service like s3, ..f.e. in develompent) when I have just images, that I'll use in stylesheet (f.e. backrounds) Icons (AppStore, Facebook ...) thanx Stylesheet images should be placed in app/assets, while files uploaded by paperclip in public/system. In case of assets , fingerprints will be created for every file, so they can be properly cached. If cached file changes, fingerprint changes too and in such way cache is

I have recently experienced an issue where I must add the following to my gemfile: gem 'execjs' gem 'therubyracer' I must do this to avoid a javascript runtime error that occurs when starting the rails server. I would like to have this modification added to all new gemfiles created with the rails new command. You're looking for application templates .

Given any valid HTTP/HTTPS string, I would like to parse/transform it such that the end result is exactly the root of the string. So given URLs: http://foo.example.com:8080/whatsit/foo.bar?x=y https://example.net/ I would like the results: http://foo.example.com:8080/ https://example.net/ I found the documentation for URI::Parser not super approachable. My initial, naïve solution would be a simple regex like: /\A(https?:\/\/[^\/]+\/)/ (That is: Match up to the first slash after the protocol.) Thoughts & solutions welcome. And apologies if this is a duplicate, but my search results weren't

I'm trying to do the following using Arel and according to the Arel doc it should work. u_t = Arel::Table::new :users l_t = Arel::Table::new :logs counts = l_t. group(l_t[:user_id]). project( l_t[:user_id].as("user_id"), l_t[:user_id].count.as("count_all") ) l_t.joins(counts).on(l_t[:id].eq(counts[:user_id])) When I do that I get the error TypeError: Cannot visit Arel::SelectManager However the author of Arel explicitly suggests that Arel can do this kind of thing. Please

My controller accesses the tempfile attribute of an uploaded file and passes it to another mocked component. My test code has @file = mock(Object) @file.stub_chain(:tempfile, :path).and_return('thefile.zip') # ... post :create, :file => @file and the controller code calls params[:file].tempfile.path . After upgrading from Rails 3.0 to 3.1, the above line started failing with undefined method `tempfile' for "#[RSpec::Mocks::Mock:0x2b0d9a0 @name=Object]":String That is, Rails 3.1 converted params[:file] to a string automatically. The code works properly when tested manually through a browser. I
